PolymersCA-41 HF

CA-41 HF is a general-purpose grade polymer designed for injection molding applications. The typical applications are fish tank aquariums, key chains, sample holders etc. CA-41 HF is also used as a carrier resin for color concentrates (master batch). CA-41 HF has very high melt flow rate owing to the monomeric formulation design. It is suitable for making thin-wall molded parts or large size molded parts. This grade is ideally designed for difficult moldings that require very high flow.
