Why Choose Shandong Jingyun Rubber & Plastic Shear Spring
(1) The company has conducted in-depth research on the low temperature resistance performance of vibration damping rubber parts and seals. The low temperature resistant rubber vibration damping formula can achieve a stiffness change rate of less than 30% for rubber parts at -50 °C; low temperature resistant sealants can seal The product is used for a long time at -50 ºC, and there is no problem of low temperature sealing failure.
(2) The company has in-depth research on the flame retardant of the rubber compound, and can design the flame retardant formula according to the flame retardant grade of the customer's product to meet the requirements of high oxygen index, low smoke density and low toxicity.
(3) The formula of fatigue-resistant rubber vibration damping parts developed by the company can realize that the fatigue performance of rubber vibration damping products is more than 1.5 times higher than that of the existing formula.
