Description

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 PVC and PUR.  It can be used as the core material in the sandwich structure.

Properties:

It is closed cell cross linked regid PVC foam, with excellent specific modulus and strength.
It have outstanding fatigue properties, inpact resistance and low water absorption. It also has good insulation properties.
It has 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
It has good water resistance and not rotten. It has good fire resistance.
It can widely be used in wind energy, marine, sports, railway and aerospace industries. 
The density ranges 45-250 kg/m3

Applications:

Wind energy:rotor blades, nacelles
Marine:hulls, decks, bulkheads, superstructures, interiors
