Q1: What are the primary processing methods suitable for Shanghai Lianjing 195ASH TPU Elastomer?
A: 195ASH is specifically formulated for melt-processing techniques including extrusion, injection molding, and two-component (2K) thermoplastic polyurethane overmolding. Its balanced melt viscosity and thermal stability support consistent flow and good surface finish across these processes.
Q2: How does 195ASH differ from standard aromatic TPU grades in terms of performance?
A: As an aliphatic TPU elastomer, 195ASH offers significantly improved UV resistance and long-term color stability compared to aromatic TPUs. It maintains mechanical integrity and clarity under prolonged outdoor exposure, making it preferred for applications where yellowing or surface degradation must be minimized.
Q3: Is 195ASH compatible with common engineering thermoplastics for co-extrusion or multi-material assemblies?
A: Yes — 195ASH demonstrates good interfacial adhesion with substrates such as ABS, PC, and certain polyolefins when processed under optimized temperature and residence time conditions. Bond strength and compatibility may be further enhanced through surface pretreatment or use of functionalized tie layers.
Q4: What drying requirements should be followed prior to processing 195ASH?
A: Like most hygroscopic TPUs, 195ASH requires thorough drying before processing to prevent hydrolysis and surface defects. A typical recommendation is drying at 80–90 °C for 3–4 hours using a desiccant dryer, with moisture content maintained below 0.05% by weight.
