The important structure of V-belts---Polyester Cable Cord A. Cover Fabric: Wear Resistant bias cut Neoprene Rubberized Fabric; B.Tensile Member: Treated Polyester Cable Cord with high Tenacity, low Stretch for higher power carrying capacity of belt; C. Cushion Member: Heat Resistant Cord embedding Cushion Rubber Compound for Static and Dynamic Adhesion to the Cord and  gives Higher Flex Life; D. Compression Rubber: Specially Compounded High Modulus Compression Rubber for support to  the Cord and better Wedging Action to  the belt. Polyester Filament Yarn is used in manufacturing of polyester tire cord fabric and seat belts, hoses, Polyester Cable Cord etc. V-Belt reinforcing fibers should be high in strength with low elongation maintained against the load, and have high fatigue resistance capable of withstanding repeated extensions. Polyester cable cord , RFL dipped ,have Excellent adhesiveness with rubber. With changes trending to small-size, high-speed operation, reinforcing fibers with high durability for the conditions of flexing and compression are required. The polyester reinforcing fibers maintained high strength and are capable of meeting all the conditions required of the V- Belt, such as high modulus and high thermal resistance. Shijiazhuang Persen Import&Export Co.,Ltd. is ISO 9001 certificated manufacturer of fiber framework materials for rubber . owns great technical power, advanced equipment and about 20 years production experience ,also Special Specification is available on request.
