Sun Plastech is launching its new UF2 purging compound, which is said to be ideal for blown and cast film extrusion, as well as injection molding. Like other Asaclean grades, UF2 is said to enable faster changeovers, resulting in increased productivity and cost savings. It can be purged through a die, effectively removing gels and color and carbon contamination that is not carbonized. Providing excellent compatibility with PE, the product is recommended for color changes, hot runner cleaning and shutdown/sealing. As it does not work by chemical reaction, there is no soak time or hold-up time.

Asaclean is also showcasing its N-Series of chemical purging compounds from its 2015 acquisition of Novachem: NCR Grade (formerly Supernova Regular), a versatile, high performance chemical purging compound well suited for color and material changes in thermoplastic injection molding and extrusion machines. NCT Grade (formerly Supernova HT), is a chemical purging compound for high-temperature resins such as Ultem, PEEK and LCPs that can process at temperatures as high as 750 F. NCF Grade (formerly Supernova FD), is a high-performance chemical purging compound well suited for color and material changes for thermoplastic film systems, including both flexible and rigid PVCs. NCH Grade (formerly Hybrid 400), is a high-performance compound said to offer the benefits of both mechanical and chemical purging agents and be suited for color and material changes in thermoplastic extrusion and extrusion blow molding machines.
