GLS soft TPEs can be overmolded onto rigid plastic, metal, or other substrates using a variety of techniques, including: Overmolded parts will take longer to cool because the TPE is only cooled from one side as the plastic substrate has poor thermal conductivity.

The plastic mass is then shaped into filaments, spun, and texturized into an already-dyed yarn. Avient is certified ACC Responsible Care®, a founding member of the Alliance to End Plastic Waste and certified Great Place to Work®.
