Estane® 58271 TPU
Estane 58271 is an 85A polyester-based thermoplastic polyurethane (TPU) designed for extrusion and molding applications. This grade offers good mechanical strength, chemical resistance and adhesive properties combined with a wide processing window. Estane 58271 provides high tensile strength, good elasticity and reliable abrasion resistance, making it suitable for technical film and molded TPU components.
Key Features:
- Polyester-based TPU
- Hardness: 85 Shore A
- High tensile strength (51.7 MPa)
- Good chemical resistance
- Good adhesion properties
- Wide processing window for extrusion
- Good tear strength and abrasion resistance
- High elongation (540%)
Processing Form:
- Blown Film Extrusion
- Flat Die / Cast Film Extrusion
- Injection Molding
- Blow Molding
Processing Notes:
Prior to processing, the material should be dried at 104°C (220°F) for 2–4 hours using a desiccant dryer to achieve a moisture level below 0.02%.
Typical extrusion temperatures range from approximately 177–193°C depending on the zone configuration.
Purpose:
Application:
Used for blown and cast TPU film extrusion as well as injection and blow molding of durable flexible 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.
