Estane® 58236 NAT 019 TPU
Estane 58236 NAT 019 is an anti-block masterbatch developed for the blown film market and designed for use with thermoplastic polyurethane (TPU). This additive improves film handling by reducing the coefficient of friction and preventing tackiness in finished TPU films. Even at a low concentration of approximately 5%, the masterbatch provides effective anti-blocking performance.
The masterbatch is fully compatible with both polyester- and polyether-based TPU materials. In addition to film applications, it can also be used in cable, hose and profile extrusion to produce smoother surfaces and reduce gloss in the final article. Estane 58236 NAT 019 is FDA approved, making it suitable for regulated applications where compliance is required.

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.
