Description: * Environmental protection and basic safety material, highly purity environmental protection rubber, SGS environmental protection test, no matter at high temperature And at normal temperature, no odor, environmental protection and non -toxic. * It has excellent acoustic insulation and an excellent shock absorption effect, effectively isolates the noise of the tires of the vehicle, the noise of the road and the noise of the engine, and has a effect of reduction of shocks and shock absorption. * Sweet texture, good resistance to weathering, not easy for aging, long lifespan * texture Light and fine, large damping, in accordance with the trend of the light automobile, do not increase the load, reduce fuel consumption; Large damping, strong resistance to tensile, high extension to rupture, can improve the safety and operability of vehicles. soft and elastic * There is a self-adhesive material on the back, which is Soft and elastic as a whole. It can be deformed in different forms of veneer, so that the construction is low. * waterproof and resistant to humidity, with excellent water vapor permeability, no water absorption, not mold, long lifespan Specifications: The butylic rubber sound insulation shock absorber is made of butyle rubber and other polymer materials as main raw materials, supplemented by some high special modified damping materials , with the appropriate quantity of fillers, softeners and anti-aging agents. It is a kind of strong tenacity, high amortization, covered with a layer of aluminum foil and a layer of butyl rubber, which can effectively reach sound insulation and shock absorption, and has Super resistance to oxidation. The embossing can improve the vibration reduction effect and is specially designed. The honeycomb shape can absorb a little noise. Name: antichoc noise insulation plate Color: black and random silver Weight: about 0.7kg Material: Liberation paper aluminum plaque in butyle rubber Specification: 400 * 230mm The package includes: 1 * Antichoc sound insulation plate (black and silver random) indefinite
