        1. sound absorption

          Product Details

          The various good points that our company has car sound insulation of  production, sound absorption, interior materials, other same kind products and cannot liken:

          1、The sound insulation characteristics grow well and the material of the warm sound insulation of normal 5cm satisfies sound insulation in case of the normal immediately and can require it.
          2、High sound absorption efficiency: Passing through inspection, the test result of the thick product of 5cm as NRC (the coefficient of cocoon cost that got impatient to fall to put together): The space where 0.90 is very big if then we raise density and thickness to be promoted to with its performance
          3、The incombustibility is strong: The PP (polypropylene) has excellent heat resistance and can have possibilities to be to be able to use it under temperature of 110 degrees for a long term. The fireproof-related (incombustibility) materials completely fit it for car interior and demand that an effect can raise the life and property safety. I equip it with inspecting a central experiment after national firefighting qualitatively, and inspecting it and reach it for a stage of building material combustion performance national standard-like GB8624B1
          4、The environmental protection performance is superior and: An environmental protective material of the high technology, avirulent dryness, it is any volatile gas very. Passing through inspection, the environmental protection characteristics reach for a stage of national standard GB18580-2001E1 and touch it when human body skin and how sensitive phenomenon cannot appear. 
          5、Against the seismic intensity decrease being good in spite of an effect and: Average the PP (polypropylene) materials, and is reliable, and, having elasticity, a lot of toughness, is strong in friction; and-resistant; tear it up, and the shock resistance degree is extremely strong potentially.
          6、One of dampproofing waterproofs it and: The insecticide of being corrupt that we endured does not have mold growing, and a certain unpleasant smell occur of the smell. The sound absorption coefficient is unchangeable, and, under humid environment, the quantity of water absorption is not beyond 1% of oneself weight and easy voidness of sentiment. A PP (polypropylene) water absorption rate: 0.01%.
          7.    The prevention of aging changes and: For environmental bottom of 120 degrees Celsius, consecutive 1,000 hours, we change in biding awhile before taking action of the food boiled in sugar syrup.
          8.    The plasticity are strong: The structure is close, and the form is stable and, And it compresses it but the deformability adapts to the space of different standards or the closeness, and the property is flexible, and the weight is arbitrary at all lightly, it could be cut and easy to attach. We can use rubber, pressure-sensitive tape, supersonic wave boil over and weld it and stick heat pasting or the pushpin.
          9. High insulation characteristics: The PP (polypropylene) has the insulation performance of the excellent high frequency, and, as for the water absorption, the late insulation performance is hardly thereby affected by the humidity.
