Engineering plastic properties & list

Engineering plastics are a group of plastic materials that have better mechanical and/or thermal properties than the more widely used commodity plastics (such as polystyrene, PVC, polypropylene and polyethylene). Being more expensive, engineering plastics are produced in lower quantities and tend to be used for smaller objects or low-volume applications (such as mechanical parts), rather […]

7 fillers to enhance the performance of virgin PTFE sealing

PTFE (Polytetrafluoroethylene) has become a commonly used material in sealing applications where other materials do not meet temperature, chemical compatibility, friction, or wear requirements. Many users are unaware that “fillers” may be added to PTFE in order to enhance certain characteristics not found in virgin PTFE. Virgin PTFE possesses “creep” behavior that may reduce effectiveness […]


Extrusion Materials – Polymeric Materials

Polymeric materials are widely extruded into various products, using sophisticated extrusion machines such as extruder and others. The finished products are used for consumer as well as industrial applications. This extrusion process is an integrated one, in which extruder involves one of the components of the complete line. On the basis of the requirement of […]


PTFE Materials & Porous PTFE Plastic Polymer

Polytetrafluoroethylene (PTFE) is a versatile polymer used in a broad range of medical, industrial, and high technology applications. Porous PTFE is inert, making it unreactive to most chemicals, and, it can work in high processing and operating temperature environments (500°F / 260°C continuous). Porex porous PTFE offers excellent thermal, electrical, mechanical, and chemical properties as […]


The physical properties of PTFE

Polytetrafluoroethylene (PTFE) is very non-reactive and is often used in containers holding reactive and corrosive chemicals. According to DuPont, its melting point is 600 K (327 °C; 620 °F). It maintains high strength, toughness and self-lubrication at low temperatures down to 5 K (-268.15 °C; -450.67 °F), and good flexibility at temperatures above 194 K […]


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 […]

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 […]
