PFA welding film TSF21 is a thermoplastic fluoropolymer film that melts on heating and joins PTFE fabric belts permanently. Available in 25 and 50 mm width on rolls of 90 metres.<\/p>\n

Why PFA and not adhesive<\/h2>\n

PTFE is practically impossible to bond with adhesive; the very non-stick property that distinguishes the material in service prevents an adhesive joint. PFA is chemically related but melts at a lower temperature. It therefore fuses with the PTFE and forms a material-to-material, heat-resistant joint.<\/p>\n

How an endless belt is made<\/h2>\n

The belt ends are placed together mitred or butted, the welding film is positioned between or over them, and the joint is welded under pressure and heat, usually with a welding press or a heated bar. Once cooled, the seam is load bearing.<\/p>\n

Width and ordering<\/h2>\n

25 mm suits narrow belts and repairs, 50 mm wide belts and more heavily loaded seams. Supplied in full rolls of 90 metres.<\/p>\n

Frequently asked questions<\/h3>\n

What temperature does welding require?<\/h4>\n

The exact temperature depends on the welding equipment; PFA melts well below the decomposition temperature of PTFE.<\/p>\n

Is the seam as strong as the belt?<\/h4>\n

Executed cleanly the seam achieves high strength but remains the load-limiting point.<\/p>\n

Why only complete rolls?<\/h4>\n

The film is converted into a sealed 90 metre roll.<\/p>\n","protected":false},"excerpt":{"rendered":"
