What You'll Learn
Pebax is a thermoplastic elastomer (TPE)
Pebax elastomers are block copolymers, which means they are made up of different polymer blocks. Specifically, Pebax is composed of rigid polyamide blocks and soft polyether blocks. This combination gives Pebax its distinctive properties. One of the key advantages of Pebax is its low "hysteresis loss," which refers to the intrinsic energy loss during flexural cycling. Pebax elastomers exhibit exceptionally low hysteresis loss, resulting in high energy efficiency.
Additionally, Pebax elastomers maintain their flexibility and performance over a wide temperature range. They do not tend to stiffen or embrittle at lower temperatures, nor do they soften or lose elasticity at higher temperatures. This temperature stability further enhances the versatility of Pebax in various applications.
Pebax has found widespread use in the sports industry, particularly in sports shoes, cleats, and ski boots. Its lightweight and energy return properties have contributed to numerous world records and athletic achievements. Pebax is also used in medical devices such as angioplasty catheters, where its strength, flexibility, and manoeuvrability are crucial. Furthermore, Pebax is suitable for industrial film applications that require the durability and toughness of polyamide resin (nylon) coupled with the ability to bend, draw, and flex repeatedly.
The Pebax Rnew range is worth mentioning as it is partially bio-based, derived from castor oil, a renewable resource. This range offers the same performance characteristics as traditional Pebax while contributing to sustainability initiatives.
