FEP, PFA and PTFE are some of the most inert materials known to man, and they also have a very high temperature resistance for polymeric materials. This means that they are ideal materials for the protection of components in applications where highly corrosive or solvent conditions exist.
Using combinations of our custom manufacturing techniques in conjunction with our thermoforming processes, we can offer a fluoroplastic encapsulation service and we can encapsulate almost any item in FEP, PFA and PTFE.
Once applied all FEP, PFA & PTFE coatings are fully inspected and spark tested to ensure the integrity of the seal.
Our FEP heat shrink is widely used in the encapsulation process and we can offer closed end heat shrinkable covers, with solid or hemispherical tips. We can accurately control the thickness and the tip profile.
FEP coatings are generally used on temperature and level detection sensors and glass protection applications.
PFA has a higher working temperature than FEP at +260°C.
The raw polymer is available in an ultra higher purity rating for extremely sensitive applications, such as semi-conductors and microelectronic devices, food and beverage processing, and pharmaceutical and biotechnology systems.
Spray coating is an alternative solution for metal components and complex profiles. PTFE is applied to the component, and any areas that do not require coating can be masked off. The nominal coating thickness is 35-40 micron.
PTFE Teflon® spray coating offers corrosion resistance, a non-stick surface and high working temperature for use in fasters in off-shore applications, plastic mould tools and commercial bake ware.
