Estane® D91T86 NAT 01 TPU
Estane D91T86 NAT 01 is an aliphatic polycaprolactone-based thermoplastic polyurethane (TPU) with a hardness of 88 Shore A. This grade is designed for injection molding applications requiring excellent colour stability under UV exposure together with strong mechanical performance. The translucent resin provides high elongation, good abrasion resistance and strong tear strength, making it suitable for durable outdoor components.
Key Features:
- Aliphatic polycaprolactone-based TPU
- Hardness: 88 Shore A
- Excellent colour stability under UV exposure
- Translucent resin
- High elongation and tensile strength
- Good abrasion and tear resistance
Processing Form:
- Injection Molding
Processing Notes:
Prior to processing, Estane D91T86 NAT 01 TPU should be dried at 90°C (194°F) for approximately 2 hours using a vacuum or dehumidifying dryer. The recommended dew point is -40°C and the moisture content should be below 0.02%. Typical injection molding temperatures range from approximately 170°C to 185°C depending on processing conditions.
Purpose:
Application:
Used for injection molded outdoor components requiring UV colour stability, durability and flexibility.
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.
