Q1: What is the primary functional role of Absopulse 810/1998.1 CF TPE in thermoplastic elastomer formulations?
A: Absopulse 810/1998.1 CF TPE functions as a high-efficiency processing aid and melt flow enhancer, specifically designed to improve extrudability, reduce melt viscosity, and support uniform dispersion of fillers and additives in TPE compounds without compromising final mechanical integrity.
Q2: Is Absopulse 810/1998.1 CF TPE compatible with common TPE base polymers such as SEBS, TPE-S, and TPO blends?
A: Yes — it demonstrates broad compatibility with styrenic block copolymers (e.g., SEBS), thermoplastic vulcanizates (TPVs), and polyolefin-based TPEs. Compatibility is typically confirmed through standard melt blending trials under typical processing conditions.
Q3: How should Absopulse 810/1998.1 CF TPE be incorporated into a TPE compound during manufacturing?
A: It is recommended for direct addition during the compounding stage — either via side-feeding or pre-blending with polymer pellets — followed by thorough melt mixing at standard extrusion temperatures. Pre-drying is not required, but storage under dry, cool conditions is advised to maintain handling consistency.
Q4: Does this product affect the surface appearance or post-processing behavior of finished TPE parts?
A: When used within recommended dosage ranges, it generally supports improved surface smoothness and reduced die buildup, contributing to more consistent part aesthetics and enhanced compatibility with secondary operations such as printing, bonding, or overmolding.
