Q1: What is Lubrizol TPU D12T85 primarily used for?
A: Lubrizol TPU D12T85 is a high-performance thermoplastic polyurethane (TPU) designed for demanding extrusion and injection molding applications, especially where excellent melt stability, clarity, and abrasion resistance are required—such as in medical tubing, specialty films, and premium consumer goods.
Q2: Is TPU D12T85 suitable for medical or food-contact applications?
A: While TPU D12T85 is formulated with high-purity raw materials and exhibits low extractables, formal regulatory compliance (e.g., USP Class VI, ISO 10993, or FDA food-contact status) must be verified on a case-by-case basis through final formulation testing and regulatory review. Lubrizol provides supporting documentation to aid qualification efforts.
Q3: How does TPU D12T85 differ from standard polyester- or polyether-based TPUs?
A: TPU D12T85 features a proprietary soft-segment architecture that balances hydrolytic stability with enhanced thermal processability and optical clarity—offering improved resistance to moisture-induced degradation compared to many conventional polyester TPUs, while maintaining better mechanical resilience than typical polyether grades.
Q4: What drying conditions are recommended before processing?
A: To ensure optimal melt quality and physical properties, TPU D12T85 should be dried using desiccant-assisted equipment at 70–80 °C for 3–4 hours prior to processing. Residual moisture content should be maintained below 0.02% for best results.
