Q1: What is the primary functional role of BASF B98A 10 in TPU formulations?
A: BASF B98A 10 is a thermoplastic polyurethane (TPU) elastomer designed to enhance melt processability, improve surface finish, and provide balanced mechanical performance—particularly elasticity, abrasion resistance, and low-temperature flexibility—in extruded or injection-molded TPU parts.
Q2: Is BASF B98A 10 compatible with other TPU grades or polymer blends?
A: Yes, B98A 10 exhibits good compatibility with aromatic and aliphatic TPU resins, as well as certain engineering thermoplastics such as PC and ABS when used in alloy systems—though compatibility should be verified experimentally for each specific formulation and processing condition.
Q3: What are the recommended drying conditions prior to processing?
A: To ensure optimal melt stability and mechanical properties, B98A 10 should be dried thoroughly before processing—typically at 70–80 °C for 3–4 hours using a dehumidifying dryer, as residual moisture can lead to surface defects and molecular weight degradation during melt processing.
Q4: Can BASF B98A 10 be used in applications requiring regulatory compliance for food contact or medical devices?
A: B98A 10 is not pre-certified for food-contact or medical applications; its suitability for such uses depends on final formulation, processing history, and end-product testing against applicable regional requirements—customers must conduct full regulatory validation including extractables/leachables assessment where required.
