Q1: What is Kaiyin TPE 201 primarily used for?
A: Kaiyin TPE 201 is a thermoplastic elastomer modifier designed to enhance flexibility, impact resistance, and melt processability in polyolefin-based compounds—commonly applied in soft-touch overmolding, automotive interior parts, and consumer product grips.
Q2: Is Kaiyin TPE 201 compatible with polypropylene (PP) and polyethylene (PE)?
A: Yes, it exhibits good compatibility with both homopolymer and copolymer PP, as well as HDPE and LDPE. Optimal dispersion is achieved through standard twin-screw extrusion under typical processing temperatures for polyolefins.
Q3: How should Kaiyin TPE 201 be incorporated into a formulation?
A: It is typically introduced during compounding via side-feeding or masterbatch dilution. Dosage depends on the desired balance of softness and mechanical integrity, generally ranging from 0.1% to 2% by weight in base polyolefin systems.
Q4: Does Kaiyin TPE 201 require drying before processing?
A: While not highly hygroscopic, it is recommended to store in sealed containers and condition at ambient humidity-controlled conditions. Pre-drying is generally unnecessary unless exposed to prolonged high-humidity environments.
