Radiation cross linked polyolefin foam (IXPE) fine pore structure to reduce the independence of the air flow caused by energy exchange with the sound barrier, shock caused by the transfer to achieve the quiet acoustic performance and thermal insulation effect of noise; independently by the strong stomatal have After pressure from the recovery (also known as memory) has the effect of damping shock; molecular structure of the polyolefin itself effectively prevent the penetration of water molecules to achieve the effect of blocking water impermeable; also has strong corrosion resistance. As a car roof and door panels of the material, a cushion to reduce noise effects, elegant indoor atmosphere, the internal space to create gentrification. http://www.ly-ixpe.com/
