- High elongation (500%)
- Good tensile strength (22 MPa)
- Excellent tear strength (72 kN/m)
- Abrasion resistance (45 mm³)
- LOI: 23% and UL94 V2 rating (2.0 mm)
- UL temperature rating: 90°C
Processing Form:
- Extrusion
Processing Notes:
Prior to processing, Estane ZHF 90AT2 NAT 055 must be dried at 100°C for 4 hours using a vacuum or dehumidifying dryer. Recommended dew point is -40°C with a maximum moisture content of 0.02%. Typical extrusion temperatures range from approximately 160°C to 190°C with a target melt temperature of 165–175°C.
Purpose:
Flame Retardant
Application:
Used for extruded components such as strips requiring flame retardancy, flexibility and strong mechanical performance.
Delivery Form:
Pellets
Key Sustainability Features of Estane TPU
Bio-Based Content
The Estane ECO TPU series incorporates renewable materials, with bio-based content ranging from 20% to 69%, certified according to ASTM D6866.
Biomass Balance Approach
The Estane RNW TPU line utilizes mass-balanced biomass feedstocks, reducing reliance on fossil-based sources while maintaining the quality and performance of standard petroleum-based resins.
Reduced Carbon Footprint
Implementing sustainable feedstocks in Estane RNW TPU products has achieved up to a 59% reduction in product carbon footprint, contributing to lower greenhouse gas emissions.
Performance Consistency
TPUs deliver the same high-quality performance as traditional TPUs, ensuring that sustainability enhancements do not compromise material integrity.
