Plastic Welding Type
Plastic welding is welding for semi-finished plastic materials, and is described in ISO 472 as a process of uniting softened surfaces of materials, generally with the aid of heat (except solvent welding). Welding of thermoplastics is accomplished in three sequential stages, namely surface prepara...Read More -
Four Most Popular Rotary Shaft Seals Material Options and How They Compare
Evolution of Seal Materials The evolution of seal materials evolved as seals faced more rugged demands. Early needs could be met using packed hemp or leather, but as the demands became more and more rigorous new materials were sought. This led to the introduction of natural rubber sea...Read More -
Polymer PTFE – Fine Powder Lubricated Extrusion Resin
PTFE is a very useful material because it has a unique combination of properties. PTFE is chemically inert, weatherable, excellent electrical insulation, high temperature resistance, a low coefficient of friction and non-adhesive properties. Shrinkable tubing is also used as roll covers and to pr...Read More -
Fluoropolymer (PTFE) Hose Industrial Applications
Fluoropolymer hoses are widely used in chemical processing, chemical transfer, chemical filling, and compressed gas transfer/filling applications. Hoses are lined with PTFE, FEP or PFA and can be reinforced with a range of materials such as rubber … All of the Fluoropolymer hoses consist of...Read More -
Common thermoplastic materials – thermosoftening plastic
A thermoplastic, or thermosoftening plastic, is a plastic material, a polymer, that becomes pliable or moldable above a specific temperature and solidifies upon cooling. Most thermoplastics have a high molecular weight. The polymer chains associate through intermolecular forces, which weaken rapi...Read More -
Fluorinated ethylene propylene VS PTFE
Fluorinated ethylene propylene or FEP is a copolymer of hexafluoropropylene and tetrafluoroethylene. It differs from the PTFE (polytetrafluoroethylene) resins in that it is melt-processable using conventional injection molding and screw extrusion techniques. Fluorinated ethylene propylene was inv...Read More
