Q1: What is the primary function of Kraiburg HTC8715/55 TPE in thermoplastic elastomer formulations?
A: HTC8715/55 TPE is a high-performance processing aid and compatibilizer designed to improve melt flow, reduce viscosity, and enhance dispersion of fillers or additives in TPE compounds—particularly in SEBS- and TPE-S-based systems.
Q2: Is HTC8715/55 TPE suitable for applications requiring food contact compliance?
A: While HTC8715/55 TPE is formulated with non-toxic, FDA-acknowledged base components, final regulatory compliance depends on the complete formulation, processing conditions, and end-use requirements. Users must conduct full regulatory evaluation and testing for their specific application.
Q3: How does HTC8715/55 TPE affect surface appearance and gloss in finished TPE parts?
A: It typically promotes improved surface smoothness and consistent gloss by facilitating better polymer chain mobility during processing and reducing surface defects caused by poor filler wetting or phase separation.
Q4: Can HTC8715/55 TPE be used in overmolding applications involving polypropylene or polyethylene substrates?
A: Yes—it is commonly employed to improve adhesion between TPE layers and semi-crystalline polyolefin substrates, especially when optimized through thermal and rheological matching during two-shot or multi-material injection molding.
