By adding extra fillers to the mix, such as carbon, graphite, anti-static and ceramic, it is possible to boost these exceptional properties even further! Find out more about our Fluoroplastic Tubes.
Typically, fluoroplastics do not melt, so they need to be processed using special tooling and techniques. But once this is done, there are many different industries that PTFE, FEP and PFA can be used into great effect.
Being able to function in extremely high temperatures and non-corrosive to all acids, fluoropolymers are often used to make gaskets, vessel linings, pump interiors, washers, rings, seals, spacers, dip tubes and well-drilling components.
Fluoroplastic Films are well used in heated processes within manufacturing and laboratory test environments. In electrics, they are used as excellent insulators for wire and cable wrapping. Being inert, they can be used for chip manufacturing and encapsulating heaters.
Their non-toxic, completely smooth surface means that they are also often used in the medical and pharmaceutical, food and drink, and cosmetics industries, as microbes just cannot gain a foothold.
Silicone Rubber comes in a variety of forms, adhesives, sealants, moulding rubbers for reproduction, encapsulants and potting compounds for electronics and coatings.
Silicone polymers are usually flowable liquids which are cured to form a flexible silicone elastomer or rubber. Additives provide additional characteristics such as adhesion, colour, thermal conductivity to mention a few. Silicone rubber is especially resistant to high temperatures and attack from moisture or chemicals.
As silicone sealants they are widely used in the construction industry with excellent adhesion to glass and ceramics and plastics.
In electronics they are used as adhesives, encapsulants and coatings providing high temperature resistance and being increasingly used for thermal transfer in high power or heat generating applications.
What is Viton?
Viton Rubber is a brand name of DuPont for its synthetic rubber and fluoropolymer elastomer, commonly used in O-rings and other molded or extruded products. This family of elastomers comprises copolymers of terpolymers of tetrafluoroethylene (TFE), hexafluoropropylene (HFP) and vinylidene fluoride (VDF or VF2), vinylidene fluoride (VDF) and hexafluoropropylene (HFP) as well as perfluoromethylvinylether (PMVE) containing specialty polymers. DuPont were the first to really market this family of materials, so Viton has become the most commonly associated name with this fluoropolymer family. There are four families of Viton polymers, and the fluorine content of these most popular Viton grades varies between 66 and 70%. The main grades are A (Dipolymers of VF2/HFP), which has a fluorine content of 66%; B (Terpolymers of VF2/HFP/TFE), which commonly used for seals or gaskets and contains 68% fluorine; F (Terpolymers of VF2/HFP/TFE), which is used in oxygenated automotive fuels and has 70% fluorine content; and finally specialty types (such as GLT, GBLT, GFLT & Viton Extreme), which are used in automotive and oil exploration applications.
