PVC & PTFE Material Comparison

Polytetrafluoroethylene (PTFE) is a synthetic material accidentally invented in the late 1930s while a chemist was endeavoring to develop a new type of perfluorethylene-based refrigerant. Rather than achieving a chlorofluorocarbon, the scientist was surprised to find that the perfluorethylene used in the process reacted with the iron content of its container and polymerized under pressure. […]

Tube Extrusion

Single Screw Extruder

Single screw extrusion is one of the core operations in polymer processing and is also a key component in many other processing operations. The foremost goal of a single screw extrusion process is to build pressure in a polymer melt so that it can be extruded through a die or injected into a mold. Most […]

Fluoric polymers (PTFE/PVDF)

Fluoropolymers have excellent, almost universal chemical resistance. They can be used both at high and very low temperatures (-260 to +260°C). They also possess outstanding resistance to weathering (UV-stability). Due to the low coefficient of friction, they are often used as sliding materials or as corresponding additives in other high-performance plastics. TECAFLON PVDF (PVDF) Polyvinylidenefluoride […]

Rod Extrusion Machine

Twin screw extrusion technology

How does extrusion work? Extrusion processing aims to physico-chemically transform continuously viscous polymeric media and produce high quality structured products thanks to the accurate control of processing conditions. Twin screw extruders consist of two intermeshing, co-rotating screws mounted on splined shafts in a closed barrel. Due to a wide range of screw and barrel designs, […]

Fluoropolymers Properties

Fluoropolymers Properties

Properties Fluoropolymers are produced from alkenes in which one or more hydrogen atoms have been replaced by fluorine. The most important members are polytetrafluoroethylene (PTFE), polychlorotrifluoroethylene (PCTFE), poly(vinyl fluoride) (PVF) and poly(vinylidene fluoride) (PVDF) Due to the weak van der Waals forces, polyfluoroolefins have a very low coefficient of friction and very low surface tension […]

Properties of PTFE and Some Other Insulating Materials

PTFE (Polytetrafluoroethylene) Teflon ® The combination of chemical and physical properties of PTFE is a consequence of its true fluorocarbon structure. This unusual structure leads to a material which has an almost universal chemical inertness; complete insolubility in all known solvents below 300°C; excellent thermal stability; and unsurpassed electrical properties, including low dielectric loss, low […]

Polymer Compounding

Polymer Compounding

In a majority of instances, the polymer formed in the reaction is modified to fabricate a particular product, or to suit the needs of a customer who will use the product for a very specific application. As mentioned earlier, compounding is often a multi-step operation that can occur partially or wholly once the resin has […]

Polymer Productction

Thermosets. Facilities that produce/formulate thermoset polymers typically describe the initial reaction phase as “condensation” polymerization. During the reaction, a condensate is formed when unreacted and partially reacted monomers and additives, in combination with water molecules released in the reaction, vaporize, cool, and then collect in a condenser or series of condensers. This condensate, if not […]
