We convert a comprehensive range of elastomer and polymer sheet materials into precision-engineered components for a wide variety of industries. Our range spans multiple material types, each selected to perform reliably in demanding environments — from extreme temperatures and aggressive chemicals to potable water systems and food-contact applications.

 

Below you will find details on each material type, the products we can produce from it, and how we process these materials in our facility.

 

 

High Friction Polymer (HFPM)

​

Our High Friction Polymer (HFPM) is a 0.8mm flexible sheet material manufactured from a blend of specialty polymers encapsulating a viscose non-woven core. It is designed specifically to deliver a high coefficient of friction on both surfaces, providing reliable grip between mating components without the need for adhesive or fixings. The material is available in blue, black, red, yellow, green, and white, which aids colour-coding and product identification. It is available as both sheet and roll stock.

​

​

EPDM (Ethylene Propylene Diene Monomer)

​

EPDM is a synthetic rubber known for its outstanding resistance to weathering, ozone, and UV exposure, making it one of the most widely used sealing materials for outdoor and exposed applications. Our EPDM range is available in several grades spanning 60 to 70 Shore A hardness, with a working temperature range of -30°C to +130°C (down to -40°C in selected grades). All grades are 100% EPDM polymer compound and offer excellent resistance to dilute and concentrated acids and alkalis. EPDM maintains a reliable compression set over time, ensuring gaskets and seals remain effective in service.

Specialist grades within the range extend the material's capabilities further:

• WRAS Approved Grade — approved for contact with potable (drinking) water, making it suitable for plumbing and water treatment applications.

• Metal Detectable Blue FDA Grade — formulated with FDA 21 CFR 177.2600 and EU 1935/2004 food-contact compliance, with metal detectability built in — an essential safety requirement in food and pharmaceutical manufacturing environments.

• UL94 V-0 Flame Retardant Grade — meets the UL94 V-0 flammability classification and carries anti-static characteristics, suitable for electrical, rail, and other fire-critical applications.

​

Neoprene (Polychloroprene)

​

Neoprene is a versatile synthetic rubber offering a good balance of mechanical performance, chemical resistance, and weather durability. Our Neoprene range covers hardness grades from 50 to 80 Shore A, providing flexibility to match the precise stiffness required for any application. The working temperature range is -30°C to +120°C, with good low-temperature performance confirmed at -40°C in harder grades.

Neoprene demonstrates good resistance to ozone and UV, and performs well in contact with mineral oils (paraffinic and naphthenic), animal and vegetable oils, dilute acids, and alkalis. It also resists fuel (up to defined swell limits), making it appropriate for many automotive and marine environments. Neoprene’s strong tensile strength and tear resistance allow it to handle demanding mechanical duty.

Our UL94 V-0 Flame Retardant Neoprene grade extends the range into fire-critical applications. This grade passes the UL94 V-0 flammability test and meets the French NF F16-101 M2 fire classification with F3 smoke density and toxicity ratings — relevant to rail and public transport sectors.

​​​​

Nitrile Rubber (NBR)

​

Nitrile rubber is one of the most widely specified elastomers where resistance to mineral oils, petroleum, and hydraulic fluids is required. Our range covers five hardness grades from 40 to 80 Shore A, giving considerable scope to match the mechanical requirements of each application. Softer grades (40–50 Shore) offer higher elongation and compliance; harder grades (70–80 Shore) provide greater tear resistance and dimensional stability under load.

The working temperature range is -30°C to +120°C across most of the range, with harder grades rated from -20°C or -15°C at the low end. Volume swell in standard ASTM reference oils is very low — nitrile tends to show minimal or slightly negative swell in lighter oils, demonstrating strong oil resistance. All grades are 100% nitrile polymer compound and are tested to BS 903 standards. Good resistance to dilute acids and alkalis is a further benefit; concentrated acids and solvents are not recommended.

​​​

Butyl Rubber (IIR)

​

Butyl rubber is characterised by its exceptional resistance to ozone, oxidising acids, and alkalis — both dilute and concentrated. It has a very low gas permeability compared to most elastomers, making it valuable wherever an airtight or chemical-resistant barrier is required. Our grade is 65 Shore A hardness with a working temperature range of -40°C to +125°C, offering reliable performance in both low-temperature and elevated-temperature environments. Heat ageing stability is good, with minimal change in hardness, tensile strength, or elongation after exposure to elevated temperature.

​​​

Viton A Fluoroelastomer (FKM)

​

Viton A is a fluoroelastomer (FKM) offering the broadest chemical and thermal resistance in our rubber range. It maintains its properties across an operating temperature range of -20°C to +275°C — considerably higher than any other elastomer we stock — and retains performance in contact with oils, fuels, solvents, dilute and concentrated acids, and alkalis. Ozone resistance is excellent. The grade is 75 Shore A hardness and carries an anti-static characteristic. The high fluorine content of Viton gives it a high specific gravity (2.00 g/cm³) relative to other rubbers. It is specified in applications where other elastomers cannot withstand the chemical or thermal conditions required.

​​​​

Hypalon (CSM — Chlorosulfonated Polyethylene)

​

Hypalon is a high-performance synthetic rubber offering excellent resistance to ozone, UV, and weathering, combined with a notably higher upper temperature limit than EPDM or Neoprene. Our grade operates across a range of -30°C to +180°C, making it one of the most thermally capable rubbers in this range. It offers excellent resistance to dilute acids and alkalis, good resistance to concentrated acids and alkalis, and good performance against oils — a combination that makes Hypalon suitable for aggressive chemical service environments. The hardness is 65 Shore A.

​​​

Natural Rubber (NR)

​

Our natural rubber range is supplied to BS1154 Z50 and Z60 grades, offering 50 and 60 Shore A hardness respectively. Natural rubber is noted for its high tensile strength (up to 170 kg/cm²), excellent elongation at break (400–500%), good tear resistance, and good abrasion resistance — properties that make it well-suited to demanding mechanical and engineering applications. The working temperature range is -20°C to +70°C. Natural rubber does not perform well in contact with oils, solvents, or fuels, and is susceptible to ozone degradation over time, so it is best suited to indoor or enclosed environments where these exposures are not a concern.

​​​​

Silicone Rubber

​

Silicone rubber offers the widest thermal operating range of any material in our range, performing reliably from -60°C to +230°C in continuous service, with intermittent peaks to +250°C. This makes it the material of choice when temperature extremes — whether low or high — rule out other rubber types. Our general-purpose silicone range spans Shore A hardnesses from 20 to 80, covering applications from very soft, compliant seals through to firm engineering components.

Silicone is inherently resistant to ozone, UV, oxidation, weathering, cosmic radiation, and corona discharge — properties that make it suitable for long-term outdoor and electrical applications without degradation. It has excellent electrical insulation characteristics, including high dielectric strength and very high volume resistivity. The range carries multiple approvals and certifications including FDA 21 CFR 177.2600 (food contact), EU Directive 1935/2004, WRAS (for grades up to 85°C in potable water contact), aviation flammability standards FAR/JAR/CS 25, REACH, and RoHS.

Within our silicone range we also stock BISCO® HT-6240, a specialist transparent solid silicone at 40 Shore A. Available in thicknesses from 0.25mm to 3.18mm and supplied in roll form, it is optionally available with an acrylic or silicone pressure-sensitive adhesive pre-applied (from 0.79mm thickness). Its optical clarity makes it valuable in applications where visual inspection through the component is required.

​​​​

PVC (Polyvinyl Chloride)

​

Our PVC range comprises two flexible sheet grades suited to different application requirements. The standard black flexible PVC grade (77 Shore A) is a cost-effective material offering good flexibility, a light transmission above 80%, and useful airborne sound insulation of approximately 30 dB. It remains flexible down to -35°C and has a working temperature range of -15°C to +50°C. It is self-extinguishing and meets US MVSS 302 flammability requirements.

The clear flame retardant PVC grade is a 2mm transparent sheet classified to DIN 4102 B2 (self-extinguishing), with good tensile strength and elongation in both crosswise and lengthways directions. Its clarity makes it suitable where visibility through the component is needed, while the flame retardant formulation is appropriate for fire-sensitive environments. Both grades are supplied in sheet and roll form.
