Polyethylene powders are commonly used in epoxy resins, varnishes and paints.
The exact powder micron size will be determined by the end use.
A lower micron size product such as HMPE35A can be used in varnishes.
A mid range micron product such as HMPE75A is used in epoxy resins.
Higher micron sizes such as HMPE301A and HPME125A are used in paints.
