Crosslinked polyethylene foam
Crosslinked polyethylene (XLPE) foams have various kinds of applications, such as thermal insulation, floatation, automotive trim, and sports goods.
The advantages of crosslinking, prior to foaming are that high quality closed cell structure can be achieved which gives the following benefits a) increased mechanical properties, b) increased resistance and recovery from deformation, c) increased thermal resistivity, d) reduced vapour and liquid transport, e) to improve elevated temperature and load bearing characteristics of the foam, f) to permit secondary moulding and foaming without collapse of the cell structure.
