Ecological car sound insulation antichoc plaque Ecological car and tasteless damping plaque in Rubber butyl pure Description: The Hi -COURCH COLD Insulation shock absorber is made of butyl rubber and others Polymers and main raw materials, supplemented by some high-special modified special depreciation materials, with the appropriate quantity of filler, softening 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: approximately 0.34kg Material: Liberation paper aluminum plaque in butyl rubber Specification: 400* 230mm Specifications: * Environmental protection and basic safety material, high purity environmental protection rubber as matrix as matrix , SGS environmental protection test passed, no matter at high temperature and at normal temperature, no smell, environmental protection and non -toxic. * It has excellent acoustic insulation and the effect of 'Shock absorption, effectively isolates the noise of the tires of the vehicle, the noise of the road and the noise of the engine, and has an effect of reduction of shocks and shock absorption. * Sweet texture, good resistance to Matters, not easy for aging, long lifespan * Light and fine texture, 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 vehicle safety and operability. * 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 The package includes: 1 * antichoc sound insulation plate (black random and silver)
