Environmental protection damping plate is made of special butyl rubber and thermoplastic elastomer as the main material, with high-efficiency environmental protection flame retardant, high-efficiency heat-resistant, barrier and sound-absorbing materials, so that it has both sound-absorbing and barrier functions and high loss factor. 

This product does not contain pollution packing and other components. It is green, non combustible, excellent aging resistance, oil resistance, acid resistance, alkali resistance, seawater resistance, and mildew resistance. High strength, excellent toughness, especially suitable for damping noise reduction of warships, ships, submarines, high-speed locomotives, large buses and so on. The greater the mass area density of the high-density and high-efficiency damping sound insulation pad is, the better the sound insulation effect is, especially for the noise in the middle and high frequency range. However, because any material has resonance effect and coincidence effect, the sound insulation trough appears in some frequency bands, reducing the overall sound insulation effect. Therefore, increasing the damping and density can greatly improve the sound insulation effect of the material.

Puzmai high efficiency and high density damping pad is a new type of sound insulation material developed by German advanced technology. The material is refined with butyl rubber as the base material. It has excellent wide-band sound insulation performance and high damping performance. It is an excellent multi-purpose sound insulation and damping material. Pcmape high density and high efficiency damping sound insulation board is characterized by making full use of the quality law and damping principle of building acoustic materials, with sound insulation capacity of more than 24 decibels; 

pasted on the surface of steel plate and other materials, with sound insulation capacity of more than 5 decibels; compared with similar materials produced in Japan, Spain and other countries, pcmape has better fire resistance, elasticity, flexibility and tensile strength; green and environmental protection, no It contains formaldehyde, benzene, asbestos, radioactive substances and other harmful ingredients to human body; one side is provided with a layer of binding sound-absorbing cloth, which improves the sound-absorbing function of the material; it can be cut with wallpaper knife, scissors and other tools, which is convenient for construction. Pcmape is widely used to composite with metal plate and other materials to improve the sound insulation effect;

it is applied to the sound insulation treatment of building ceiling to improve the sound insulation effect between floors; it is used in combination with the floor sound insulation pad to increase the floor impact sound and air sound double isolation sound effect;

 it is applied to the sound insulation transformation of homes, hotels, restaurants, KTV, recording studio, studio and other places It is applied to noise control products such as sound insulation door, sound insulation barrier, sound insulation cover, etc.; it is applied to the development of low-noise products such as computer, household appliances, etc. it is applied to the sound insulation, vibration suppression, damping, etc. of machine tools, locomotives, car doors, trunk, engine compartment, etc.
