Pebax
Thermoplastic Elastomer
Description
Pebax resin is a thermoplastic elastomer made of flexible polyether and rigid polyamide.
Pebax Elastomers - A family of lightweight polymers that offer unmatched energy return and cold temperature durability for dynamic applications.Pebax thermoplastic elastomers consist of polyamide and polyether backbone blocks. These specialty elastomers offer very low material density, a wide range of shore hardness values, extremely efficient energy return (over a wide temperature range) and are optionally biobased.
Main applications:
Flexible injected parts.
High performance power trasmission belts.
Silent gears.
Injection molding
Processing conditions:
Typical melt temperature (Min / Recommended / Max) : 200°C / 240°C / 270°C.
Typical mold temperature : 10 - 30°C.
Drying time and temperature : 4-6 hours at 60-70°C.
For many years, Pebax elastomers have become famous for their outstanding combination of lightweight (typically 20% lighter than competitive polymers) and tremendously efficient energy return. Their "hysteresis loss" (intrinsic energy loss during flexural cycling) are among the lowest in the world. Further, Pebax elastomers tend to maintain this flexural efficiency advantage over a wide temperature range - in other words, they tend not to stiffen/embrittle at lower temperature, and they tend not to soften or lose elasticity at higher temperatures.The inherent combination of lightness, toughness, flexibility and outstanding energy return has helped establish Pebax resins as the reference polymers in several sports applications.
Pebax elastomers are also recommended for a wide range of industrial film applications where the traditional durability and toughness of polyamides resin (nylon) is required, but also the ability to bend, draw, and repeatedly flex.
Pebax Elastomers are block copolymers made up of rigid polyamide blocks and soft polyether blocks. Manipulating these blocks and their relative ratio allows for the creation of a large range that spans the flexibility spectrum from very hard and rigid to very soft and flexible, without the need for plasticizers. These unique polymers maintain the highly desirable combination of the toughness traditionally associated with polyamides and the flexibility/elasticity more often seen with polyethers/polyesters.
