Such as natural rubber, due to having good mechanical properties and processing performance, are widely used applications, but its heat oxygen aging, ozone resistance, oil resistance and chemical resistance poor. Most synthetic rubber poor processability, mechanical properties are not satisfactory, often difficult to produce, these synthetic rubber and natural rubber blend used, complementary performance, especially improved synthetic rubber products z workability. Each part of the tire rubber is widely used NR, SBR, BR, etc. and use, and if using 90/10 CR. / NR blends manufacture V-shaped tape, NR only improved the CR during kneading and rolling the sticky roll phenomenon also improved low temperature performance of the tape. Blended with each other between the synthetic rubber used, the same effect of improved performance. IIR manufactured as a single tire inner tubes, although tightness good, but there will be a long time to use the carcass soft, sticky tire and tube defects such as size increases, if IIR EPDM blended with a small amount of use, is able to effectively overcome these deficiencies, thanks to the structural changes occurring after crosslinking based EPDM rubber thermal aging. A small amount of EPDM rubber because it can increase the amount of carbon black and softening oil, but also to improve the surface smoothness and shrinkage of the extruded semi-finished tube. Special synthetic rubber and synthetic rubber blends common or special use, can effectively keep the rubber makes M performance, but also effectively reduce the cost of production of products, improve the utilization of special rubber. The blend fluorine rubber and acrylic rubber, silicone rubber blended with EPDM rubber, fluorine rubber and nitrile rubber ^ mixtures and the like.
