SILICONE COATED POLYESTER TIRE CORD
Tire cord fabric is a type of industrial fabric which is constructed using High Tenacity yarns in the warp direction and yarns of negligible resistance in weft direction which is used to hold warn yarns locked in their position. Tire cord coated fabrics provides fundamental properties such as controlled deformation, high strength, abrasion resistance, etc. Widely used by the tire industry, it is also employed for the rubber hose manufacture, air springs, expansion joints, among many other applications.
Polyester is a the synthetic fiber that detains the first place in terms of global production. It is a linear polymer whose mass comprises predominantly (at least 80%) of the ester functions and terephthalic acid. The polyester yarn is lightweight and flexible. It is resistant to ultraviolet radiation. Low flammability. It softens at 245 ° C and melts at 250 ° C. It keeps a good shape memory and can therefore be used into coated fabrics composition. Furthermore, a suitable weaving also allows good heat dissipation.
Silicone Rubbers 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
