Q1: What is the primary application domain for WRT-155/40 TPEE?
A: WRT-155/40 TPEE is primarily used in high-performance thermoplastic elastomer applications requiring a balance of toughness, elasticity, and thermal stability — especially in automotive components, industrial hoses, and flexible connectors where dynamic mechanical performance is critical.
Q2: How does WRT-155/40 differ from standard polyester-based TPEEs?
A: WRT-155/40 is formulated to deliver enhanced melt processability and improved low-temperature flexibility compared to conventional TPEEs, while maintaining strong hydrolytic resistance — making it particularly suitable for applications exposed to variable thermal and humid conditions.
Q3: Is WRT-155/40 compatible with common engineering thermoplastics for blending or co-processing?
A: Yes, WRT-155/40 demonstrates good compatibility with polyesters (e.g., PET, PBT) and certain polyolefins when properly compounded, enabling use in alloy systems for tailored hardness, impact resistance, and processing behavior.
Q4: What processing methods are recommended for WRT-155/40?
A: WRT-155/40 is optimized for standard thermoplastic processing techniques including injection molding, extrusion, and blow molding. Pre-drying at 80–100 °C for 2–4 hours is strongly recommended prior to processing to ensure optimal mechanical properties and surface quality.
