PTFE (Polytetrafluoroethylene) is a versatile, high performance fluoropolymer composed of carbon and fluorine atoms. While similar in structure to polyethylene (PE) and polypropylene (PP), PTFE carbon chain is shielded by fluorine atoms (Figure 1). This carbon-fluorine bond is known as 'one of the strongest bonds in organic chemistry' (dissociation energy: 460 KJ/mol) and as a result, gives PTFE exceptionally high chemical and thermal resistance.
Our expertise in sintering porous plastics enables us to produce high quality, PFOA/PFAS-free, sintered Vyon® PTFE with consistent pore size, permeability and pore size with no compromise on performance. Although PTFE is commonly associated with non-stick applications in the food industry, PTFE is widely used the life science, medical and pharmaceutical applications for its hydrophobic properties, high mechanical and chemical resistance.
