Q1: What is the primary application domain for Shanghai Taixiang 2100-90N TPE?
A: This thermoplastic elastomer is primarily engineered for soft-touch overmolding applications—especially on rigid substrates such as PP, PS, ABS, and PC—where excellent adhesion, flexibility, and tactile comfort are required. It is widely used in consumer electronics housings, automotive interior trim, and hand-held tool grips.
Q2: Is 2100-90N compatible with standard injection molding equipment?
A: Yes, it processes reliably on conventional injection molding machines without requiring specialized hardware. Typical melt temperatures range between 170–210 °C, and mold temperatures are generally maintained at 20–40 °C. Drying is recommended prior to processing to minimize surface defects.
Q3: How does 2100-90N perform in terms of adhesion to common engineering plastics?
A: It demonstrates strong inherent adhesion to polypropylene (PP) and polystyrene (PS), and good bonding to ABS and PC—particularly when optimized for temperature and residence time. Surface treatment or primers are typically unnecessary for most overmolding configurations.
Q4: Can this TPE be colored or compounded with additives?
A: Yes, 2100-90N is fully compatible with standard pigment masterbatches and functional additives such as UV stabilizers, flame retardants, and antimicrobial agents—provided they are thermally stable within its processing window. Coloration is typically achieved using low-loading masterbatches to preserve mechanical performance.
