Q1: What is the primary processing method for Merrell TPUH870?
A: Merrell TPUH870 is designed for melt-processing techniques including extrusion, injection molding, and calendering. It exhibits good thermal stability and melt homogeneity under standard TPU processing conditions.
Q2: Is Merrell TPUH870 suitable for applications requiring flexibility and abrasion resistance?
A: Yes — as a thermoplastic polyurethane elastomer, TPUH870 offers excellent elasticity, tear strength, and surface durability, making it well-suited for demanding dynamic applications such as footwear components, industrial hoses, and protective coatings.
Q3: How does moisture affect processing of Merrell TPUH870?
A: Like most TPU grades, Merrell TPUH870 is hygroscopic and requires thorough drying prior to processing — typically at 80–90 °C for 2–4 hours — to prevent surface defects, reduced mechanical performance, or hydrolytic degradation during melt processing.
Q4: Can Merrell TPUH870 be blended with other polymers?
A: Yes — TPUH870 demonstrates compatibility with certain engineering thermoplastics and elastomers, particularly other TPU grades and some polyesters. Compatibility should be confirmed through rheological and morphological evaluation in the intended blend system.
Q5: Does Merrell TPUH870 contain plasticizers or halogenated additives?
A: No — Merrell TPUH870 is a non-plasticized, halogen-free thermoplastic polyurethane elastomer formulated without intentionally added phthalates, heavy metals, or halogenated flame retardants.
