Q1: What is the primary function of Kraiburg HTC0459/70 TPE in thermoplastic elastomer formulations?
A: HTC0459/70 TPE is a high-performance processing aid and compatibilizer designed to improve melt flow, reduce extrusion pressure, and enhance surface finish in TPE compounds—particularly in SEBS- and TPE-S-based systems.
Q2: Is HTC0459/70 TPE compatible with common TPE base polymers such as SEBS, TPE-V, and TPE-E?
A: Yes—it exhibits broad compatibility with styrenic block copolymers (SEBS, SBS), thermoplastic vulcanizates (TPE-V), and certain polyester-based TPEs (TPE-E), though optimal performance is typically observed in SEBS-rich formulations.
Q3: How should HTC0459/70 TPE be incorporated into a TPE compound during processing?
A: It is typically added directly to the base polymer during compounding—either via side-feeding or pre-blending—and disperses readily under standard twin-screw extrusion conditions. No pre-drying is required.
Q4: Does HTC0459/70 TPE affect the mechanical properties or thermal stability of the final TPE product?
A: When used within recommended dosage ranges, it does not significantly compromise tensile strength, elongation, or thermal resistance; instead, it often supports more consistent rheological behavior and improved processability without sacrificing end-use performance.
