In the calendering process, fabric and rubber material is passed through a series of rollers to flatten, smooth and commingle the two or more materials. Calendered sheets can have multiple layers of both the elastomeric and polymer "sandwiched" together.

These Rubber Sheets are also manufactured from over 15 polymers including: Nitrile / Buna-N (NBR), Fluorocarbon (Viton®, Fluorocarbon (FKM), Silicone (VMQ), Fluorosilicone (FVMQ), Polyurethane (AU/EU), Natural Rubber (NR), Ethylene Propylene (EPDM), Hydrogenated Nitrile Rubber (HNBR), Styrene Butadiene Rubber (SBR), Chloroprene (Neoprene®), etc.
