Product Description

good comprehensive mechanical properties

Tensile strength, high tear strength, elasticity, wear resistance of medium.

Wide adjustable hardness range, commonly used 50-90 Shore A.

Excellent weather resistance, ozone resistance

Ozone resistance, sunlight resistance, aging resistance is far better than natural rubber, styrene butadiene rubber.

Outdoor long-term use is not easy to crack.

Excellent oil and solvent resistance

Resistance to non-polar oil (gasoline, mineral oil), resistance to aliphatic hydrocarbon solvents.

耐油性能优于 NR/SBR,略逊于 NBR(丁腈橡胶)。

Good flame retardancy (self-contained flame retardant)

含氯结构,离火自熄,不用大量阻燃剂即可阻燃。

常用于电缆、电线护套。

耐热、耐化学腐蚀

Long-term use temperature:-40 ℃ ~ 100 ℃, short-term up to 120 ℃.

Weak acid, alkali, animal and vegetable oil resistance.

粘接性强

Good adhesion with metal, fabric and rubber, suitable for rubber roller, conveyor belt and adhesive tape.
