Estane® RNW85 GP 52DT NAT055
Estane® RNW85 GP 52DT NAT055 is an aromatic polyether-based thermoplastic polyurethane (TPU) containing attributed renewable carbon. The material is designed for injection moulding applications and combines strong mechanical performance with improved sustainability through the use of bio-circular feedstock.
The grade offers a balanced combination of elasticity, abrasion resistance and mechanical strength, making it suitable for demanding technical components. With excellent elongation and tear resistance, Estane® RNW85 GP 52DT NAT055 performs reliably in applications where flexibility and durability are essential.
Key Features:
- Polyether-based TPU with renewable carbon content
- High elongation and tensile strength
- Excellent abrasion and tear resistance
- Good flexibility and mechanical durability
- Suitable for injection moulding processes
- ISCC Plus certified sustainable raw materials
Processing Form:
- Injection Molding
Processing Notes:
Prior to processing, the material should be dried at 100°C for 3–4 hours in a dehumidifying dryer to achieve a moisture level suitable for TPU processing. Typical injection moulding temperatures range from approximately 205°C to 220°C across the barrel zones.
Purpose:
Application:
Used for injection molded TPU components requiring flexibility, abrasion resistance and durable mechanical performance, including technical parts and industrial components.
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.
