LeatherTECH Pro™

Our LeatherTECH Pro™ comes with a 2.5mm thick profile as standard and is also available in a plus size of 2.9mm thick. For more demanding applications we also provide a Heavy option which comes in varying thickness, dependant on the width, as seen below. The finish can be matt, semi-gloss and high gloss. We can also supply, to order, grooved and beaded profiles or profiles of greater thickness. Typically our grooved profile has a square groove but could produce a round or V groove if required. Get in touch with us to tell us your requirements, we have our own on-site workshop where we can very quickly create extrusion dies for any profile we don't currently have.

StrapTECH™ comes in all the same options as LeatherTECH Pro™ and will be made to order. Without the internal webbing holding everything in place, StrapTECH™ will shrink in width after extrusion, so please note that the widths won't exactly match the LeatherTECH Pro™ widths.

Our current policy is to manufacture to order and do not typically carry stock. We may carry stock in the future for any size/colour/finish combination that we can determine from order patterns as being a common item.

When we first started the business we initially bought in our webbing, but we found that the quality of the product varied considerably from batch to batch. Looking at the better webbing manufacturers, who could give us a consistent, high quality webbing, we found that the cost of this would not allow us to make our premium synthetic leather strapping at a competitive price. We therefore took the decision to buy our own, state of the art, narrow fabric weaving looms, which allows us to maintain a very high quality webbing and retain a very attractive price for our customers.

We use a polyester 1000 denier multi filament yarn and produce a high density, tight weave that gives us a large amount of yarn packed in to a relatively thin webbing strip. This allows to provide the strength of strap only normally found in the ‘heavyweight’ options in all of our products, including the standard 2.5mm thick products. We believe we are the only company that offers over 1000Kg/inch tensile breaking strength in a standard 2.5mm thick strap.

Yarn is delivered directly from our creel to our loom through a tension equaliser so that the finished weave is straight and each warp is of equal tension. This is very important as it ensures that any load applied to the weave is distributed equally among all warp yarn threads. This ensures that no individual filament gets overloaded, which could cause that filament to break prematurely, compromising the ultimate strength of the webbing.

Since the development of our HiBOND+™ technology, we now get such a strong bond that we no longer need our webbing to have such a large surface area to bond to. This has allowed us to minimise the thickness of the webbing  without reducing number of warp filaments. We have produced a weave pattern which produces a tighter, flatter, thinner weave, yet maximises the surface texture to provide the greatest surface area without compromising the thinness. This thin, tight weave has allowed us to maintain the same breaking strength, whilst also giving enough surface area to work in conjunction with our HiBOND+™ technology to give an unparalleled bond strength.

Having a thinner weave allows us to maximise he covering of our BioMER™ coating, for the same overall thickness of the finished product, ensuring maximum protection for the underlying webbing core. At standard weight products we therefore offer far stronger webbing straps yet provide a generous protective coating. At heavy weight products, we offer the same high strength as everyone else, yet are able to give a much more generous protective coating.

With standard manufacturing processes it is not possible to have a very strong, thin webbing core, with a thick protective outer coating and have both of these strongly bonded to each other. One of these components will need to be compromised. Typically, keeping the thick outer coating on a flatter, thinner, strong webbing core, there will not be enough available webbing surface for the coating to get a good bond to. We have seen examples from other manufacturers where a brand new sample literally came apart in our hands the first time we handled it, the bond was so weak. Bulking out the webbing weave for a strong 'heavyweight' strap can increase the core webbing thickness by about 0.7mm, which means there is 0.35mm less protective coating top and bottom. In a 3.5mm thick strap this a significant percentage loss of protection.

The webbing we produce allows us to provide a product which does not compromise strength at the standard sizes and does not compromise protection at the ‘heavyweight’ sizes.

Only LeatherTECH Pro™ gives you a product that comes with zero compromises, including the price you pay.

• We have a very strong inner webbing core available as standard even in the standard thickness
• A good thick protective coating of our BioMER™ polymer
• All bonded together with industry leading bond strength
• All at an attractively competitive price

BioMER™ is our own polymer, developed to provide a superior look and feel, have a high UV stability and, most importantly, be amongst the safest polymer coatings in use. In production we can manipulate the polymer to produce outstanding looking high gloss and deep matt finishes.

BioMER™, like many other synthetic leather coatings, contains a blend of plastic compounds and plasticisers. The plasticisers are used to provide a softer, more flexible polymer and there are hundreds of different chemicals that can be used to do this job. There have been, historically, a couple of unfortunate major problems with plasticisers, both of which increase production costs in order to overcome them. The first problem is that, in the early days of plastics technology the most common and cheapest plasticisers have now been proven to be linked to a number health conditions, including increased risks of some cancers and increased infertility in men. The second major problem is the tendency of plasticisers to slowly migrate out of the compound, this is why old plastics become both less flexible and more brittle over time. Inevitably, by the time you have developed a blend of plasticisers that give the required physical properties to the final product and which are both safe and have low migration, you will find that these come with a significant increase in cost over the unsafe options.

Many of the worst chemicals used as plasticisers are now heavily regulated around the world. The largest and most well known body of regulation in effect currently is the EU's REACH regulations. This is a very large body of regulations that deals with the manufacture, use, import and export of all chemicals within the EU. So comprehensive are these regulations that many other countries are looking to adopt the these regulations themselves and to develop them into a global set of harmonised regulations. Part of these regulations are concerned with restrictions of the use of Substances of Very High Concern (SVHCs). This is relatively small list of dangerous chemicals, known to have adverse impacts on human health, of which numerous plasticisers are included. Unfortunately REACH regulations do not completely restrict the use of SVHCs. Any finished product that contains an SVHC chemical, whose quantity makes up less than 0.1% of the finished product, by mass, can be manufactured, used, imported or exported without any restriction. What's more the 0.1% limit is per chemical, so it is possible for a product to contain multiple SVHCs each going up to the 0.1% limit and still be unrestricted.

When developing our BioMER™ polymer we have used only 100% virgin materials, ensuring that it contains zero amount of SVHC chemicals and has a very low migration level. In fact the compound we've developed with our supplier is bio-compatible, this means that it is so safe we could use it to manufacture medical grade products that could be certified as safe to implant in humans.

Only the best synthetic leather strapping will have an outer coating where the manufacturer has spent the time, effort and money to develop something that is as safe as it can be, whilst also having a premium look and feel. Although we do not claim to be the only manufacturer to do this, we are part of a very exclusive club.

When you are looking for a supplier of synthetic leather strapping you will come across some very cheap options. If you are considering these cheap options, ask yourself why are they so cheap? The only answer is that it will have an industrial grade plastic coating. When it comes to plastic compounds, they can be split into 3 broad categories

• Medical grade - this is the safest grade of plastic and requires no dangerous chemicals and an extremely low level of migration.
• Food grade - this is still a very safe grade of plastic, with the main difference over medical grade being that it allows for a very slightly higher migration level.
• Industrial grade - due to the impact of REACH regulations these are very likely to be harmless, however it is still likely that they could contain some SVHC chemicals, up to the 0.1% limit. At the cheap end of the spectrum, it wouldn't be unusual to find multiple SVHCs, meaning that you could end up with something that has 1% or more SVHC content.

If you are still considering the cheap options, thinking that if the EU believe 0.1% is safe, then that is good enough for me, here is another, true, cautionary tale. There have been reported instances of European importers of cheap plastic goods having entire shipments refused entry into the EU. To try and reduce costs to the limit, these manufacturers are using the maximum amount of cheaper SVHCs that they can get away with. Unfortunately, due to poor quality control, they occasionally creep over the 0.1% limit. Unfortunately for the importer, when the shipment arrives in the EU, is subject to testing and then found that the product contains more than the permitted 0.1%, the entire shipment gets refused entry. Although we're not aware this has happened specifically with synthetic leather strapping, it's still very much relevant as the potential is always there.

HiBOND+™ is the technology we have pioneered, taking 5 years of continual development, evaluation and refinement, that delivers the industry-leading polymer to webbing bond strength. We have managed to achieved this without sacrificing any of the products light weight and flexibility, whilst also retaining a super easy to sew matrix.

Our woven webbing that is integral to LeatherTECH Pro™ provides supreme strength while the encapsulating BioMER™ polymer provides support and protection to the webbing core. Our HiBOND+™ technology ensures that the BioMER™ coating remains firmly attached to the webbing core throughout the life of the product. In use, synthetic leather strapping will typically be subjected to being bent, twisted, pushed, pulled and any combination of these forces. Due to the different physical properties of the webbing core and the polymer coating, when subject to these daily forces, they will both want to move in different ways and by different degrees, causing continual stress on the bonds between the webbing and the outer coating. Our HiBOND+™ technology is designed to easily cope with these continual daily forces to ensure the webbing core and BioMER™ coating remain firmly attached, giving full strength and performance, throughout the life of the product.

Ordinarily, when woven polyester webbing is cut or punched it is necessary to heat seal the cut surface, in order to bond the cut yarn ends to each other to prevent the webbing from fraying, and ultimately unravelling. With synthetic leather strapping, the outer coating will provide support to the cut ends of the webbing, helping to prevent fraying. However the webbing core will have a greater freedom to move within the coating at any cut surface, causing the strain on the bond between webbing and coating to greatly increase, leading them to eventually separate at the cut and fraying to occur. It is therefore still necessary to heat seal cut ends of ordinary synthetic leather strapping. When LeatherTECH Pro™ is cut, the bond is so strong that the loose, cut end, webbing fibres will remain resolutely attached to the BioMER™ coating, preventing any possibility of the webbing core to start unravelling.

Although we would still recommend heat sealing any cut ends and punched holes of LeatherTECH Pro™, let’s be honest, not everybody takes the time to do this. If this is the case, the HiBOND+™ technology in LeatherTECH Pro™ can make all the difference.
