Estane® 58280 TPU
Estane 58280 is a polyether-type thermoplastic polyurethane (TPU) compound designed for extrusion and injection molding applications. This grade offers high resiliency and unique physical properties including low tensile set, low compression set and high rebound resilience. Estane 58280 combines flexibility, durability and low specific gravity, making it suitable for applications requiring strong rebound performance and elastic recovery.
Key Features:
- Polyether-based TPU
- Hardness: 79 Shore A
- High rebound resilience (72%)
- Low tensile set and compression set
- High elasticity and flexibility
- Good abrasion resistance
- Low specific gravity
- Good hysteresis behavior
Processing Form:
- Extrusion
- Injection Molding
Processing Notes:
Prior to processing, the material should be dried for approximately 2 hours at 104°C (220°F) in a dehumidifying hopper dryer to remove absorbed moisture.
Typical extrusion temperatures range from approximately 177–210°C depending on processing equipment and conditions.
Purpose:
Application:
Used for cable jackets, hose and tubing as well as resilient molded parts such as wheel tires and rebound balls.
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.
