Estane® ZHF 80AT3
Estane ZHF 80AT3 is a non-halogen flame retardant aromatic polyether-based thermoplastic polyurethane (TPU) developed for extrusion applications. This grade combines good flexibility with strong mechanical performance and flame-retardant properties, making it suitable for technical extrusion components where safety and durability are required.
Key Features:
- Hardness: 80 Shore A
- Non-halogen flame retardant TPU
- High elongation (520%)
- Good tensile strength (28 MPa)
- Good tear strength (63 kN/m)
- Abrasion resistance (45 mm³)
- UL94 V2 rating (2.0 mm)
- UL temperature rating: 90°C
Processing Form:
- Extrusion
Processing Notes:
Prior to processing, Estane ZHF 80AT3 should be dried at 100°C for approximately 4 hours using a vacuum or dehumidifying dryer. Recommended dew point should be −40°C with a maximum moisture content of 0.02%. Typical extrusion temperatures range from approximately 160°C to 190°C with a recommended melt temperature around 170°C.
Purpose:
Flame Retardant
Application:
Used for extruded components requiring flame retardancy, flexibility and reliable 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.
