Estane® 58300 TPU
Estane 58300 is an 82A aromatic polyether-based thermoplastic polyurethane (TPU) designed for extrusion and molding applications. This grade offers good mechanical performance combined with hydrolysis resistance, excellent low-temperature flexibility and strong abrasion resistance. Estane 58300 provides reliable durability together with a wide processing window for extrusion processes.
Key Features:
- Polyether-based TPU
- Hardness: 82 Shore A
- Hydrolysis resistant
- Good low-temperature performance
- High elongation (650%)
- Good tensile strength (37.9 MPa)
- Strong abrasion resistance
- Wide processing window for extrusion
Processing Form:
- Blown Film Extrusion
- Flat Die / Cast Film Extrusion
- Injection Molding
- Blow Molding
- Cable Jacketing
Processing Notes:
Prior to processing, Estane 58300 TPU should be dried at 104°C (220°F) for 2–4 hours in a desiccant dryer to reach a moisture level below 0.02%.
Typical extrusion melt temperatures are around 179°C, depending on processing conditions.
Purpose:
Application:
Used for blown and cast film extrusion, cable jacketing and molded flexible components requiring hydrolysis resistance and low-temperature performance.
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.
