Q1: What is the primary application profile of BASF C78A TPU Elastomer?
A: BASF C78A is a thermoplastic polyurethane elastomer designed for extrusion and injection molding processes, commonly used in demanding applications requiring excellent abrasion resistance, flexibility at low temperatures, and good melt processability—such as technical hoses, industrial belts, and soft-touch overmolding components.
Q2: Is BASF C78A suitable for food-contact or medical applications?
A: BASF C78A is not pre-qualified for direct food-contact or medical device applications. Its suitability for such uses depends on full regulatory assessment by the end-product manufacturer, including compatibility with intended processing conditions and final-use requirements. Customers should consult BASF’s regulatory documentation and perform appropriate validation testing.
Q3: How does C78A compare to other TPU grades in terms of hardness and processing behavior?
A: C78A is a medium-hardness TPU grade offering a balanced combination of mechanical strength and melt flow—typically easier to process than higher-hardness TPUs while maintaining better dimensional stability than softer, more flexible grades. It exhibits good thermal stability during extrusion and responds well to standard drying and molding protocols for aromatic TPUs.
Q4: Can C78A be blended or alloyed with other polymers?
A: C78A demonstrates reasonable compatibility with certain engineering thermoplastics and other TPUs, particularly those with similar polarity and thermal profiles. However, blend performance—including morphology, phase adhesion, and mechanical retention—must be evaluated case by case. Compatibility testing and rheological screening are recommended before commercial implementation.
