Metal compounded rubber sheet (MCR) series
Compounding backing materials like Stainless steel, spring steel, mild steel plate, the surface of which has been processed chemically, and rubber, MCR utilizes the technology of liquid crystal polymer nanometer layer to modify rubber, reduces the permanent compression set rate of rubber at high temperatures, and improves the intensity and thermostability of rubber. Moreover, through the optimizing of processing and compounding techniques, it achieves the effect of high-efficiency, endurance and environmental friendliness, and is widely used in the sealing of automobile and motorcycle engine junk head and refrigeration compressor. |
