Single Layer Belts
Single layer belts are a combination of reinforcing plies and non-permeable laminates. These materials are vulcanized together to form a single rugged unit impervious to flue gases and very resistant to flue gas acids, oils, chemicals, and heat. Different belts will offer various degrees of abrasion resistance. Single layer belts are offered in either PTFE (Fluoroplastic), Elastomer or Fluoroelastomer varieties.

Elastomer and Fluoroelastomer: Reinforced EPDM, Silicone, and FKM (Fluoroelastomers). PAPCO Series 300SL, 400SL FSA/FKM, and Silflex.
Note: All Fluoroelastomers from PAPCO are guaranteed to meet FSA-DSJ-401-02
SERIES 300SL
PAPCO Series 300SL/EPDM (Ethylene Propylene) elastomer is recommended for service temperatures that do not exceed 300°F. PAPCO 1/8˝ EPDM consists of two plies of EPDM and one reinforcement ply. PAPCO 1/4˝ EPDM consists of three plies of EPDM and two reinforcement plies. In both cases, the plies are calendared and vulcanized together to form a single rugged unit impervious to flue gases and very resistant to flue gas acids, oils, chemicals, heat, and fly ash abrasion. Reinforcing plies are available in different materials such as fiberglass, Aramid/Kevlar®, special wire inserted cloths and other unique fabrics as needed to meet your specification and application.
SERIES 400SL
PAPCO’s 400SL Fluoroelastomer (FKM) is recommended for service temperatures that do not exceed 400°F. PAPCO’s 400SL Single Layer Flexible Elements consist of multiple plies of FKM with 70% Minimum Fluoroelastomer Content combined with high strength reinforcing plies. The plies are calendared and vulcanized together to form a single rugged unit impervious to flue gases, with excellent resistance to flue gas acids, oils, heat, and fly ash abrasion. This material is also highly flexible, with movement allowable in all directions.
Our standard 1/4˝ construction is guaranteed to meet FSA-DSJ-401-02 and ASTM D6909-03 and features a 0.070˝ Fluoroelastomer (FKM) Gas Side layer.
