FAQ

Q:What's the difference between TPE compounding and TPU processing?
A:TPE compounding: Blends TPE with additives/fillers via mixing/extrusion to customize properties (e.g., hardness, elasticity). Focuses on formulating unique material blends. TPU processing: Shapes TPU raw materials (with inherent high strength/wear resistance) into products (e.g., belts, soles) via injection molding/extrusion. Focuses on controlling parameters (temp, pressure) to form products.

Q:How to ensure quality of TPR for toys?
A:Raw material check: Verify TPR composition (no harmful heavy metals/plasticizers) and test basic properties (melt flow rate). Production monitoring: Control mixing/extrusion temp, screw speed to ensure uniform ingredient dispersion. Final product tests: Check mechanical properties (tensile strength, tear resistance), safety (harmful substance release), and appearance (no bubbles/impurities).

Q:What are key traits of TPV automotive sealing strip production?
A:Process: Select TPV (with additives for weather resistance), extrude (control temp ~180-220°C), then cool, cut, and surface - treat (or embed metal strips). Advantages: TPV's thermoplastic nature enables efficient continuous extrusion. Its aging resistance and compression set performance suit long - term automotive dynamic sealing needs.
