Q1: What is the primary functional role of Weike TPU 89043D in thermoplastic polyurethane formulations?
A: Weike TPU 89043D functions as a high-performance processing aid and melt-flow modifier, designed to enhance extrudability, reduce melt viscosity, and improve surface finish in TPU-based compounds—particularly during film blowing, calendering, and injection molding.
Q2: Is Weike TPU 89043D compatible with both aromatic and aliphatic TPU base resins?
A: Yes, it demonstrates broad compatibility across common aromatic and aliphatic TPU grades, including polyester- and polyether-based systems. Compatibility should be verified under actual processing conditions due to formulation-specific variables such as molecular weight distribution and additive load.
Q3: How does Weike TPU 89043D affect the mechanical properties of the final TPU product?
A: At typical usage levels, it maintains key mechanical attributes—including tensile strength, elongation at break, and tear resistance—while significantly improving process stability. Over-addition may lead to slight reductions in modulus or hardness, so dosage should be optimized per application requirements.
Q4: What are the recommended storage and handling conditions for Weike TPU 89043D?
A: Store in original sealed packaging at temperatures between 5 °C and 30 °C, protected from moisture, direct sunlight, and contamination. Prior to use, ensure material is dry—especially if processing involves high-temperature operations where residual moisture could cause surface defects or hydrolysis.
