Antichoc plaque of acoustic carout carout car-toe pure butyle carout PURCEUP 1PCS Acoustic insulation antichoc plaque Durable anti-shock protection Description: The acoustic insulation shock absorption butyle is made from rubber Butyl and other polymer materials as main raw materials, supplemented by special modified damping materials, with an appropriate quantity of charges, softeners and anti-aging agents. It is a kind of strong hardness, high amortization, covered with a layer of aluminum foil and a layer of butyl rubber, which can effectively obtain sound insulation and shock absorption, and has a great resistance to oxidation. The embossing can improve the vibration reduction effect and is specially designed to absorb noise. Name: antichoc plaque for sound insulation Color: Black and silver random Weight: about 0.34kg Material: Butyl rubber + aluminum plate + non -stick paper Specification: 400* 230mm Characteristics: * Basic environmental and safety protection material, butylic rubber protection of the ' High purity environment as a matrix, SGS environmental protection test, regardless of high temperature and normal temperature, no smell, environmental protection and non -toxic. * It has excellent insulation phonic and a shock absorption effect, effectively isolates the noise of vehicle tires, road noise and engine noise, and has a shock reduction effect and shock absorption. * texture Sweet, good weather resistance, not easy to age, long lifespan * Light and thin texture, large damping, online with the trend of car lightness, so as not to increase the load, reduce fuel consumption ; Large damping, high resistance to tensile, high extension to rupture, can improve the safety and operation of vehicles. * 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 waterproof to humidity, with excellent water vapor permeability, no water absorption, not mold, long lifespan Package included: 1 * antichoc sound insulation plate (black and random silver)
