Briefing
It is a cross-linked rigid structural PVC foam material. as a close cell foam, based on vinyl polymer, modified with the throughout Aramids link. It is the compounding chemical material based on PVCand PUR. It is said as the cross-linked PVC foam core, in the international practice
Properties
closed cell cross linked regid PVC foam, with excellent specific modulus and strength.
have outstanding fatigue properties, inpact resistance and low water absorption. It also has good insulation properties.
have both the good size stability and machinability, compatible with various sandwich structure processing methods, compatible with various resin systems. It is the ideal core material for te light weight high strength sandwich composite core material. The processing temperture ranges from -240ºC to +100ºC, the long term operation temperature ranges from -240ºC to +80ºC
have good water resistance and not rotten. have good fire resistance.
can widely be used in wind energy, marine, sports, railway and aerospace industries.
