Neoprene rubber is formed by polymerization of neoprene monomer. It is a polar rubber between saturation and unsaturated. The vulcanized rubber has relatively good ozone resistance (better than NR, SBR, NBR, worse than EPDM, IIR), weather resistance, chemical corrosion resistance and aging resistance. At the same time, it also has good mechanical properties, flame retardant and good wear resistance, low temperature elasticity, good resistance to distortion, resistance to dichlorodifluoromethyl methane and ammonia refrigerant, dilute acid resistance, resistance to silicone ester lubricating oil, but not resistant to phosphate ester hydraulic oil, easy crystallization at low temperature, hardening, poor storage stability, in the mineral oil with low aniline point expansion.
Temperature range: -40℃ ~ 100℃, short time up to 125℃
Advantages:
· Good elasticity and good compressive property
· The recipe contains no sulfur and is very easy to make
· Resist animal and vegetable oils
Physical properties are not affected by fat, fat, multiple oils and solvents
