Traditionally, Carbon fiber tows were used in thermoset composite applications but are being incorporated into thermoplastics more and more.

We specialize in color and additive technologies, offering both standard and customized solutions across all silicone platforms: High Consistency Rubber (HCR), Liquid Silicone Rubber (LSR), Room Temperature Vulcanization (RTV), as well as many other thermoset carrier systems.

Now the benefits of thermoplastic materials are available also for the applications traditionally produced from ceramics or thermoset plastic materials. • Part weight reduction • Low loss tangent • RoHS & REACH compliant solution • Halogen- and heavy metal-free solution • Recyclable Copyright © 2022, Avient Corporation.
