Accuracy and Mold Direction of PTFE Products
Introduction：In general, the accuracy of PTFE product is not easy to control because its coefficient of linear expansion is higher than that of metals, and its one of volume transition temperature is around room temperature causes volume changes approximately 1 to 2%. Moreover, thin-walled PTFE ...Read more -
Production Process of PTFE
Tetrafluoroethylene was first prepared in 1933. The current commercial synthesis are based on fluorspar, sulphuric acid and chloroform. Basic Production Process of PTFE Polymer: The Manufacturing of PTFE Polymer/ Resin is basically carried out in two stages. First, TFE Monomer is generally manuf...Read more -
Extrusion of polymers
Extrusion is a process of manufacturing long products of constant cross-section (rods, sheets, pipes, films, wire insulation coating) forcing soften polymer through a die with an opening. Polymer material in form of pellets is fed into an extruder through a hopper. The material is ...Read more -
Polymer adsorption
Adsorption is the adhesion of ions or molecules onto the surface of another phase.Adsorption may occur via physisorption and chemisorption. Ions and molecules can adsorb to many types of surfaces including polymer surfaces. A polymer is a large molecule composed of repeating subunits bound togeth...Read more -
Polycarbonates (PC) vs Polymer PTFE/FEP Machining
Polycarbonates (PC) are a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonates used in engineering are strong, tough materials, and some grades are optically transparent. They are easily worked, molded, and thermoformed. Because of these propert...Read more -
Processing and machining of PTFE parts
PTFE is known for it’s stability and resistance to many chemicals. … This makes it a very versatile material, and we mould, form and machine parts in this material. Generally, PTFE is processed into semi-finished shapes with compression or iso-static moulding techniques. The PTFE resi...Read more
