Metal coatings
Processing
Conventional dip or flow techniques can be used for coating or impregnating high temperature fabrics, fibers, and other products with Everflon FEP D50.
A FEP resin coating on woven fabrics made of fiberglass, fiber, or other high-temperature resistant fibers, can be made by dip coating. Successive passes may be necessary to build the desired thickness to produce a smooth, crack-free coating. Each coating layer is usually dried to remove water (typically at 120 °C [250°F]), baked to remove the wetting agent (typically at 270 °C [518 °F]), and then heated above the crystalline melting point of the resin particles (approximately 265 °C [509 °F]). If the Everflon FEP D50 is being used as a top coat over a PTFE-coated fabric or other parts, the coating must be heated to melt the PTFE (approximately 337 °C [639 °F]) to maximize adhesion. Other solid or liquid ingredients can be added to Everflon FEP D50 to provide specific processing or finished product behavior

EverFlon fluorinated lubricant powder is a soft material of low molecular weight that is applied to form a dry lubricating film under light contact pressure. When this contact pressure continues between the two mating surfaces, either of which contains EverFlon powder, the transfer of the fluoropolymer lubricant to the opposite surface occurs. This results in the formation of a micro-thin lubricating film, which has excellent anti-friction properties.
EverFlon MV1 is a fragile PTFE powder that can be broken down into submicron particles by high shear mixing in a liquid medium. The degree of particle size reduction depends largely on the degree of shear.
For example, mixing MV1 with a medium viscosity lubricant and then passing the mixture twice through a three-roll grinder yields a sub-micron size range, with many particles measuring 0.3 microns in size.
MV1 is particularly suitable for inks added to can coatings as well as oils, greases and elastomers Medium.

In the semiconductor and pharmaceutical industries, PFA HP (High purity) tubing is used in fluid handling applications that require very low levels of chemically extractable matter.
ETFE is a fluoropolymer that is chemically and structurally similar to polyolefins (such as polyethylene) and therefore has higher wear resistance, impact resistance and crushing resistance than its perfluorinated (perfluoropolymer) counterparts -PTFE, FEP and PFA.
ETFE tubes are commonly used in wire harnesses, outer film applications that require weather resistance, and tank linings that require special chemical and wear resistance. Its high tensile strength at 25 ° C also leads to higher operating pressures at that temperature.
If your temperature requirements are up to 260�°C (500�°F), PTFE tubes (polytetrafluoroethylene) are recommended. When terminated, it can be prevented from "melting" by soldering iron. Due to its excellent dielectric properties, it is widely used in electronic and electrical services. Another major advantage of PTFE tubes is their non-stick properties, allowing the material to be transported with minimal fluid resistance. Note, however, that PTFE reacts with fluorine, molten sodium hydroxide, and molten alkali metals.
We have a full range of PTFE extrusion tubes for protecting wiring or transporting fluids in critical applications.
PTFE tubes are available in a variety of configurations and custom designs. PTFE tubes have inherently excellent chemical resistivity and low coefficient of friction, and their performance is superior to that of glass and graphite, making them ideal materials for fluid transport.
PTFE tubes can be used with almost all industrial solvents, chemicals and corrosive materials, and can be used in high-temperature processes. It can be steam sterilized without affecting its physical properties, such as surface hardness, elongation, deflection life or load deformation.
PTFE tubes are usually translucent white, however, the whiteness varies depending on batch and wall thickness size. Colored PTFE tubes are also available and are often used to simplify tube wiring during system installation.
