Everflon FEP Aqueous Dispersion Everflon FEP D50 is an off-white aqueous fluorinated ethylene propylene (FEP) dispersion stabilized with a non-ionic surfactant. It is a general-purpose dispersion that can be used to impart some the unique properties of FEP to end products that would be difficult to make using traditional melt extrusion processes. It can be used to coat or impregnate porous structures, or to make thin films. It can be coated and melt bonded to polytetrafluoroethylene (PTFE) resin or used as a hot melt adhesive. The FEP resin in Everflon FEP D50 is a melt flowable thermoplastic, providing superior properties typical of fluoroplastic resins: retention of properties after service at 204 °C (400 °F) and useful properties at 240 °C (400 °F). Everflon FEP D50 aqueous dispersion provides: Inertness to nearly all industrial chemicals and solvents Stability at high temperatures Excellent dielectric properties Excellent weatherability Application Heat-sealable top coatings for PTFE-coated fabrics for belting, circuit boards, architectural fabrics, and electrical insulation Cast film for capacitor dielectrics or chemical barriers Hot melt adhesive for PTFE, PFA, and FEP parts 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.
What is the Difference Between a Wet Cooling Tower and a Dry Cooling Tower? 1. The volume and price distinction of wet cooling tower and dry cooling tower Generally speaking, wet cooling towers are small in size, high in efficiency, and inexpensive. In contrast, dry cooling towers are bulky, low in efficiency, and expensive. 2. The heat exchange method of wet cooling tower and dry cooling tower is distinguished (1) The heat is taken out by the cooling liquid and dissipated in the air through conduction and evaporation, which is called a wet cooling tower. The cooling gas or air takes heat out and transfers it into the air through conduction, which is called a dry cooling tower. The cooling tower that completes the wet cooling method is a wet cooling tower, and the cooling tower that implements the dry cooling method is a dry cooling tower. While the wet and dry cooling tower is actually a combination of a closed cooling tower, cooler and wet cooling tower. (2) One of the heat exchange methods between water and air in the cooling tower is that the air flowing through the surface of the water is in direct contact with the water, and the heat in the water is transferred to the air through contact heat transfer and evaporation. It is called a wet cooling tower. (3) The heat exchange efficiency of the wet cooling tower is high, and the limit temperature at which the water is cooled is the wet bulb temperature of the air. However, water is lost due to evaporation; evaporation also increases with the salinity of the circulating cooling water. In order to stabilize the water quality, part of the water with higher salinity must be drained; wind blowing can also cause water loss. These water losses must be continuously replenished with enough new water. Therefore, the wet tower must have a source of make-up water. (4) In water-deficient areas, when it is difficult to replenish water, only dry cooling towers can be used. The heat exchange between air and water in the dry tower is to transfer heat through the surface of the radiator composed of metal pipes, and transfer the heat of the water or steam in the pipe to the air flowing outside the radiator. The heat exchange efficiency of the dry tower is lower than that of the wet tower, and the limit temperature of cooling is the dry bulb temperature of the air.
