XPE made in korea
For improvement of foaming and heat insulation of resin which melting viscosity is low or best viscosity range is limited, you can make foaming upon Crosslinking and the other is Crosslinking first and foaming by decomposition of blowing agent. There are two ways for Crosslinking. Physical method is to make resin mixing and foaming with gas by decomposition of blowing agent with heating over decomposition temperature of them. For example, Non-Crosslinked foaming is by physical method, Chemically/Physically Crosslinked foaming by chemical blowing agent.
