Materials in Thermoforming

Resins and Blends

Our primary materials are HDPE, TPO and TPR resins. We have 5 large extruders, all with co-extrusion capability. Our main colors are Black, Grey, Tan, but we can process any color required. Our manufacturing capabilities for extrusion include thicknesses of 0.080” to 0.500”. 

Our material comes into the plant and all resins are tested by QA before being transferred into our silos. Resin blends are adjusted daily depending on the inventory in the plant.
