Q1: What is the primary function of SK 1040DB/DN TPE in thermoplastic elastomer formulations?
A: SK 1040DB/DN TPE functions as a high-performance processing aid and compatibilizer, enhancing melt flow, reducing extrusion pressure, and improving dispersion of fillers or additives in TPE compounds—particularly in styrenic (TPE-S) and thermoplastic polyolefin (TPO) systems.
Q2: Is SK 1040DB/DN TPE compatible with common polymer matrices used in soft-touch applications?
A: Yes—it demonstrates broad compatibility with SEBS, SEPS, PP, PE, and EVA-based TPE blends. It supports consistent surface aesthetics and tactile performance in overmolding and co-extrusion applications without compromising elasticity or thermal stability.
Q3: How should SK 1040DB/DN TPE be incorporated into a compound during processing?
A: It is typically added directly to the base polymer during twin-screw extrusion or internal mixing. Pre-blending with masterbatch carriers is also effective. Dosage depends on formulation requirements but generally ranges from 0.1% to 2% by weight for optimal processing benefits without affecting final mechanical properties.
Q4: Does SK 1040DB/DN TPE impact the recyclability of TPE products?
A: No—SK 1040DB/DN TPE is designed to remain stable through multiple thermal cycles and does not introduce crosslinking or degradation pathways that hinder mechanical recycling of TPEs. It maintains compatibility within standard reprocessing streams for post-industrial and post-consumer TPE scrap.
