Description PTFE is a synthetic fluropolymer of tetrafluoroethylene. It is a fluorocarbon solid, as it is a high molecular weight compound consisting wholly of carbon and fluorine. PTFE is hydrophobic in nature, it also has the lowest coefficient of friction against any solid.

Application Our hydrophobic polymers are used as coatings, adhesives, fibers, films and engineering plastics. Furthermore, they are widely used as biomedical polymers for vascular grafts, implants and ophthalmic applications.

Features And Benefits This product has good hydrophobicity to meet your specific application needs
