Estane® GP 52DT TPU
Estane® GP 52DT is an aromatic polyether-based thermoplastic polyurethane (TPU) designed for injection molding applications. This grade offers excellent mechanical strength, good elasticity and durable abrasion resistance. Estane® GP 52DT TPU provides reliable performance for molded technical components where toughness and flexibility are required.
Key Features:
- Hardness: 53 Shore D
- High tensile strength and elongation
- Excellent tear strength
- Good abrasion resistance
- Durable aromatic polyether-based TPU
- Supplied as translucent spherical pellets
Processing Form:
- Injection Molding
Processing Notes:
Prior to processing, Estane® GP 52DT TPU should be dried at 100°C for 2–3 hours using a dehumidifying dryer. The recommended dew point should be below −30°C and moisture content should remain below 0.05%. Typical injection molding temperatures range from approximately 195°C to 220°C depending on machine setup and processing conditions.
Purpose:
Application:
Used for injection molded parts such as durable technical components and animal identification tags.
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.
