Colmant Coated Fabrics Butyl (IIR) Rubber Sheet is a synthetic rubber developed in the 1940’s. It has exceptionally low gas permeability making it ideal for inner tubes and high pressure/vacuum sealing applications. Its very low resilience makes it suitable for shock and vibration damping. Its chemical unsaturation gives it excellent resistance to heat, ozone, and weathering, and also to dilute acids and alkalis. It is not suitable for use in mineral or petroleum based fluids.

Hypalon® CSM Rubber Sheet is to be considered an improved chloroprene as it offers better chemical resistance, ozone and light resistance, heat aging. Their particular resistance to weathering conditions and the excellent low gas permeability presents CSM as the best option for the manufacture of premium quality inflatable boats and structures for all environments, but most of all in sea environment.

Colmant Coated Fabrics SBR Rubber Sheet is one of the best options when applied to general purposes. Compared to natural rubber, SBR shows better abrasion resistance and heat-aging properties. Though, the resilience and the physical properties tend to be lower than those of Natural Rubber.

Neoprene® CR Rubber Sheet was the best option to manufacture products that are to be in contact with oils and fuels in the past. Nowadays, Neoprene® is considered to have a moderate resistance to these components. However, Chloroprene Rubber can be considered a mix solution as it has better resistance to a diverse source of degrading agents (like oil, ozone, chemicals and heat) than Natural Rubber. Instead Neoprene® presents lower physical properties. In spite of the physical properties, Neoprene® has a perfect airtightness, therefore it is widely used in the manufacture of inflatable structures of all sort. Its resistance to fire is also excellent, and can be presented in self-extinguishing formulations if required.

Colmant Coated Fabrics Nitrile (NBR) Rubber Sheet was first developed in 1941 in a project meant to find an oil resistant rubber. However, NBR’s oil resistance depends on the grade of acrylonitrile. The higher the grade of acrylonitrile the better is resistance to oil and fuel. However, as the grade of acrylonitrile increases, the endurance to low temperatures decreases. NBR has good abrasion resistance nonetheless its physical properties are moderate in comparison with the Natural Rubber.

Colmant Coated Fabrics Silicone Sheet are ideal for high and low temperature applications. Electrical properties are excellent and resistance to weathering and ozone attack is outstanding. It is not resistant to super-heated steam. Physical properties are generally low but are at least retained at higher temperatures. Gas permeability is very poor as is resistance to petroleum based fluids. Silicone rubbers are expensive in comparison to most other rubbers. Food Quality/FDA compliant grades are available for use in the food and pharmaceutical industries.

Colmant Coated Fabrics Eco Rubber Sheet has properties similar to nitrile rubber but with better heat, oil and petrol resistance. It has a low gas permeability and better low temperature flexibility than NBR. Its resistance to acids, alkalis and ozone is excellent.

Colmant Coated Fabrics Epdm Rubber Sheet is a copolymer of ethylene and propylene and a smaller amount of a diene monomer which forms chemically unsaturated ethylene groups pendant from the main saturated chain. These facilitate cross-linking reactions which do not affect the integrity of the polymer backbone. This feature gives EPDM excellent heat, ozone and chemical resistance. Physical properties are very good and resistance to polar fluids is generally good. Low temperature resistance is very good and EPDM can be compounded to give excellent electrical resistance.

Viton® FKM Rubber Sheet is a fluorinated synthetic rubber. It has excellent chemical inertness, excellent resistance to high temperatures, chemicals, lubricants, solvents and aggressive fuels. FKM also detain a good mechanical properties.

Colmant Coated Fabrics NBR/PVC Rubber Sheet is blended with PVC aging resistance is improved. Likewise, flame, ozone and petrol resistance are largely improved.

Vamac® AEM Rubber Sheet is one of the most employed rubbers for the manufacture of products summited to high temperatures while maintaining good properties against oxygen, ozone and light.

Colmant Coated Fabrics Natural Rubber Sheet is to be considered as the sole non-synthetic rubber. This particular rubber can be recycled for the reutilization, mostly for the manufacturing of tires. New methods of recycling natural rubber are under development to diminish the ecological impact of used tires and other products.
