Estane® ZHF 85AT8 NAT 01
Estane ZHF 85AT8 NAT 01 is a non-halogen flame retardant thermoplastic polyurethane based on an aromatic polyether TPU structure. The material is developed for extrusion applications where flame resistance and mechanical durability are required.
This TPU grade combines high tensile strength, excellent elongation and strong abrasion resistance with reliable flexibility. The non-halogen flame retardant formulation enables improved fire safety performance while maintaining the processing benefits typical for thermoplastic polyurethane materials.
Key Features:
- Non-halogen flame retardant TPU
- Aromatic polyether-based thermoplastic polyurethane
- Excellent abrasion resistance and tear strength
- High tensile strength and elongation
- UL94 V-2 flame rating
- Designed for extrusion processing
Processing Form:
- Extrusion
Processing Notes:
Prior to processing, the material should be dried at approximately 80°C for 3–4 hours in a dehumidifying dryer with a target dew point of -40°C to ensure optimal processing performance and moisture control.
Purpose:
Flame Retardant
Application:
Used for extruded TPU components requiring flame retardancy and mechanical durability such as cable jackets, industrial tubing, technical profiles and flexible structural parts.
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.
