Pure Butyl Rubber Practical Car Supplies Sound Insulation Shockproof Plate Environmentally Friendly Self-adhesive Material Description: Butyl rubber sound insulation shock absorber is made of butyl rubber and other polymer materials as the main raw materials, supplemented by some modified special high damping materials, with appropriate amount of fillers, softeners and anti-aging agents. It is a kind of strong toughness, high damping, covered with aluminum foil layer and butyl rubber layer, which can effectively achieve sound insulation and shock absorption, and has super oxidation resistance. Embossing can enhance the vibration reduction effect, and is specially designed The honeycomb shape can absorb some noise. Name: sound insulation shockproof plate Color: random black and silver Weight: about 0.34kg Material: butyl rubber + aluminum plate + release paper Specification: 400 * 230mm Specifications: *Environmental protection and safety base material, high purity environmental protection butyl rubber as matrix, passed SGS environmental protection test, no matter in high temperature and normal temperature, no smell, environmental protection and non-toxic. *It has excellent sound insulation and shock absorption effect, effectively insulates vehicle tire noise, road noise and engine noise, and has shock reduction and shock absorption effect. *Soft texture, good weather resistance, not easy to aging, long service life *Light and thin texture, large damping, in line with the trend of automobile lightweight, not to increase the load, reduce fuel consumption; large damping, strong tensile strength, high elongation at break, can improve the safety and operability of vehicles. *There is self-adhesive material on the back, which is soft and elastic as a whole. It can be deformed according to different forms of veneer, so the construction is low. *Waterproof and moisture-proof, with excellent water vapor permeability, no water absorption, no mildew, long life Package Included: 1*sound insulation shockproof plate(random black and silver)
