Estane® 54600 TPU
Estane 54600 is a 92A aromatic, polyester-based thermoplastic polyurethane (TPU) developed for high-performance film and sheet production. It combines very good physical properties with strong chemical resistance and a wide processing window, making it well-suited for calendering and melt coating operations as well as flat die/cast film extrusion. Estane 54600 delivers high tensile strength, excellent elongation and strong tear resistance, supporting durable end-products where toughness and flexibility are required.
Key Features:
- Aromatic polyester-based TPU
- Hardness: 92 ± 3 Shore A
- Very good physical properties and chemical resistance
- Wide processing window for calendering
- High tensile strength and elongation balance
- Excellent tear strength (Graves & Trouser)
- Low wear (Taber loss)
Processing Form:
- Melt Coating / Calendering
- Flat Die / Cast Film Extrusion
Processing Notes:
Drying is required prior to processing: 104°C (220°F) for 2–4 hours. A desiccant dryer is recommended with a target dew point of -40°C, and maximum moisture content should be 0.02%.
Recommended starting extrusion temperature profile: Zone 1: 171°C, Zone 2: 177°C, Zone 3: 182°C, Zone 4: 188°C, Adapter: 193°C, Die zones: 193°C. Suggested melt temperature mid-range: 191°C, with a screen pack recommendation of 20/40/80.
Purpose:
Tear Strength & Chemical Resistance
Application:
Developed for high-performance film and sheet production.
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.
