Estane® GP 92AT TPU
Estane GP 92AT is an aromatic polyether-based thermoplastic polyurethane (TPU) designed for injection molding applications. This grade combines high flexibility with excellent abrasion resistance and strong mechanical performance. Estane® GP 92AT TPU is well suited for molded technical components where elasticity, durability and reliable processing are required.
Key Features:
- Hardness: 92 Shore A
- High elongation and flexibility
- Excellent abrasion resistance
- Good tear strength
- Durable aromatic polyether-based TPU
- Supplied as translucent spherical pellets
Processing Form:
- Injection Molding
Processing Notes:
Prior to processing, Estane GP 92AT TPU should be dried at 100°C for 2–3 hours using a dehumidifying dryer. Recommended dew point should be below −30°C and moisture content should remain below 0.05%. Typical injection molding temperatures range from approximately 190°C to 215°C depending on machine setup and processing conditions.
Purpose:
Application:
Used for flexible injection molded components requiring elasticity, abrasion resistance and mechanical durability.
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.
