Q1: What are the key processing methods suitable for Elastollan 500?
A: Elastollan 500 is a thermoplastic polyurethane (TPU) elastomer designed for melt-processing techniques including injection molding, extrusion, and blow molding. Its balanced melt viscosity and thermal stability support consistent processing across standard equipment, with recommended drying prior to processing to maintain optimal mechanical performance.
Q2: How does Elastollan 500 compare to other TPU grades in terms of hardness and elasticity?
A: Elastollan 500 is formulated as a medium-hardness TPU, offering a favorable balance between rigidity and elastic recovery. It delivers higher tensile strength and better abrasion resistance than softer TPU grades, while maintaining greater flexibility and impact resilience compared to rigid thermoplastics such as rigid PVC or certain polycarbonates.
Q3: Is Elastollan 500 suitable for applications requiring good low-temperature flexibility?
A: Yes — Elastollan 500 retains useful elasticity and impact resistance at sub-zero temperatures, making it appropriate for outdoor, automotive, and industrial components exposed to cold environments. Performance in extreme cold depends on part geometry and stress conditions, and real-world validation under intended service conditions is recommended.
Q4: Can Elastollan 500 be overmolded onto other thermoplastics?
A: Elastollan 500 is commonly used in two-shot or multi-material injection molding processes, especially over substrates like PP, ABS, PC, and PA. Adhesion quality depends on substrate surface preparation, mold temperature, and process parameters; bonding agents or mechanical anchoring features may be employed to enhance interfacial strength where required.
