BYK introduces additives to enhance processing

BYK Chemie GmbH has developed a new type of stripping agent, BYK® P4200. The additive is used to control the small amounts of volatile components formed during the processing of thermoplastics. Odour and emissions of polyolefin compounds are often a concern, particularly for applications in automotive interiors. The company says that the additive is an easy-to-handle granulate material, which is added in the extruder. No further processing step is required and its effectiveness surpasses conventional solutions, such as adsorbents.

BYK P4101 is polymeric processing aid that interacts strongly at the particle-matrix interface. The company says that this particular interaction leads to overall improved processing conditions, such as better melt flow, while at the same time important physical properties including tensile strength, e-modulus, HDT and impact resistance are maintained or improved. This additive is designed for compounders who want to increase filler loads and/or improve mechanical strengths. The additive is a powder and is easy to incorporate, says the company.

Finally, Disperplast® 1018 is a high performance wetting and dispersing additive for colour masterbatches, which is specifically claimed to improve the dispersion of pigments. Masterbatchers will see enhanced colour strength, better filter pressure values and fewer agglomerates and black spots. The additive is wax-free – meaning no migration – and is compliant with FDA and European food contact regulations.
