Estane® 58311 TPU
Estane 58311 is an 85A polyether-based thermoplastic polyurethane (TPU) designed for extrusion applications requiring durability and flexibility. This grade provides very good mechanical properties together with hydrolysis resistance, excellent low-temperature performance and strong abrasion resistance. Estane 58311 offers a wide processing window for extrusion processes, making it suitable for technical film and profile production.
Key Features:
- Polyether-based TPU
- Hardness: 85 Shore A
- Hydrolysis resistant
- Good low-temperature performance
- High tensile strength (45.5 MPa)
- Good elongation (520%)
- Good tear resistance
- Wide processing window for extrusion
Processing Form:
- Flat Die / Cast Film Extrusion
- Profile Extrusion
Processing Notes:
Prior to processing, Estane 58311 TPU should be dried at 104°C (220°F) for 2–4 hours using a desiccant dryer to reach a moisture level below 0.02%.
Typical extrusion melt temperatures are around 185°C depending on processing conditions.
Purpose:
Application:
Used for flat die or cast film extrusion and profile extrusion requiring hydrolysis resistance and low-temperature 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.
