Frequently Asked Questions
Q: What screw design works best with TPU 3392A?
A: We recommend barrier screws with L/D ratios between 24:1 and 32:1, featuring gradual compression zones.
Q: Can this material be co-extruded with other polymers?
A: Yes, 3392A demonstrates excellent adhesion to various substrates including PVC, PET, and polycarbonate with proper tie-layer design.
Q: What drying conditions are required?
A: Pre-dry at 80-90°C for 3-4 hours with dew point maintained below -30°C to prevent hydrolytic degradation.
Q: Are custom color formulations available?
A: We offer standard color concentrates and can develop custom color-matched compounds upon request.
Q: What is the typical lead time for orders?
A: Standard grades ship within 10-14 days; custom formulations require 4-6 weeks for development and production.
Q: Do you provide technical data sheets?
A: Comprehensive TDS and MSDS documentation is available through our technical support portal or upon direct request.
