Q1: What is Kaiyin TPE 1XX primarily used for?
A: Kaiyin TPE 1XX is a thermoplastic elastomer modifier designed to enhance flexibility, impact resistance, and soft-touch feel in rigid polypropylene (PP) and polyethylene (PE) compounds—commonly applied in automotive interior trim, consumer appliance housings, and durable packaging components.
Q2: Is Kaiyin TPE 1XX compatible with common processing methods?
A: Yes—it is fully compatible with standard melt-processing techniques including injection molding, extrusion, and blow molding. Its thermal stability supports typical PP/PE processing temperatures without significant degradation or volatilization.
Q3: How is Kaiyin TPE 1XX typically incorporated into formulations?
A: It is generally added as a masterbatch or dry-blended directly into the base polymer. Dosage depends on formulation requirements but typically ranges from 0.1% to 2% by weight to achieve targeted softness and toughness improvements without compromising stiffness.
Q4: Does Kaiyin TPE 1XX require special drying before processing?
A: While not highly hygroscopic, it is recommended to store in sealed containers and condition at ambient temperature prior to use. Extended exposure to high humidity may affect surface appearance in sensitive applications, so standard drying practices for TPEs are advised.
