PolyClear HR: Colour Changing for Injection Moulding
PolyClear HR is a hybrid purging compound (a mixture of granule, powder and liquid), that combines polymer flow modification, foaming melt fracture and surfactant-based deposit removal.
It can be fully melted and is not temperature- or time-sensitive. This has several benefits: no orifice is too small; no temperature changes are required to process; and no soak time is needed to aid cleaning.
Itís the best colour change product for injection moulding of polyolefins on the market today.
