Q1: What is the primary application profile of Ningbo Sanbo N93950 TPE?
A: N93950 is a thermoplastic elastomer formulated for soft-touch overmolding and flexible component manufacturing, especially in consumer electronics, automotive interior trim, and hand-held device grips where resilience, tactile comfort, and adhesion to rigid substrates like PP or ABS are required.
Q2: Is N93950 compatible with common injection molding equipment and processing conditions?
A: Yes — N93950 is designed for standard injection molding and two-shot molding processes. It typically processes at melt temperatures between 170–210 °C, with mold temperatures ranging from 20–50 °C. Drying is recommended prior to processing to maintain optimal surface quality and mechanical performance.
Q3: How does N93950 perform in terms of adhesion to thermoplastics?
A: N93950 exhibits strong inherent adhesion to polypropylene (PP), polyethylene (PE), and ABS without requiring primers or surface treatments under optimized processing conditions. Bond strength may vary depending on substrate cleanliness, mold temperature, and interfacial residence time during co-molding.
Q4: What are the key handling and storage recommendations for this TPE?
A: Store N93950 in its original sealed packaging in a cool, dry environment away from direct sunlight and sources of heat or humidity. Prior to processing, condition the material at ambient temperature for at least 2 hours if removed from climate-controlled storage, and use desiccant drying when moisture sensitivity is a concern for final part appearance or physical properties.
