Moulds Plus International has introduced in the market two developed grades of Ultra Purge that are designed to purge clear PC and PMMA applications. The two grades have evolved from the Ultra Purge 5060 grade. Ultra Purge will be at Plastec West in Anaheim at booth 4127.
Molding clear and transparent automotive lenses as well as medical devices is a particularly difficult application because the slightest imperfection shows up on these types of parts, the company stated. As a result, Moulds Plus International has designed grades specific for PMMA and PC. The Ultra Purge PMMA (designed for Acrylic) and the Ultra Purge PC (designed for PC) are low residue grades that are effective for color changes, carbon removal and material changes.
