The main benefit of PTFE coatings (including Teflon) could be the non-stick properties from the material, which means applications like commercial bakeware have excellent non-stick / release properties and so are a breeze to clean.
We now have created array of PTFE coating systems with many different good things about suit most applications. The function that the coating shall be employed for as well as the operating conditions will define selecting the proper coating for the job.
Within this blog, we explore a number of the benefits in greater detail.
NON-STICK AND RELEASE
A PTFE coating placed on a factor will offer excellent non-stick/release properties which is a breeze to scrub. This kind of coating can also be excellent at preventing both cold and hot products from permanently adhering to the substrate and so is widely used inside the cookware, confectionery, food processing and bakery industries. PTFE coatings will also be used for non-stick from the packaging, heat sealing, moulding, automotive, aerospace, chemical and pharmaceutical industries.
NON-WETTING
PTFE surfaces are hydrophobic and oleophobic, and will not readily wet. This permits the material to self-clean. For your semiconductor industry, this property is vital as it allows all chemical media to own off and turn into collected.
TEMPERATURE RESISTANCE
PTFE coatings can service arduous application conditions involving extremes of temperature. They could remain stable at advanced temperatures of +260°C as well as for short periods at +290°C. PTFE works extremely well on extrusion dies and sealing of plastic/elastomers where other remedies may degrade or cause clogging of molten material. These coatings can also perform at cryogenic temperatures and can remain stable at -270°C.
LOW FRICTION AND ABRASION RESISTANCE
PTFE coated surfaces reduce friction and may achieve suprisingly low coefficients of friction, typically from about 0.04 to 0.15. Where oils and grease evaporate at elevated temperatures PTFE remains which is therefore perfect for shafts, bearing surfaces, moving mechanisms, stud bolts and fasteners. With regard to added abrasion resistance and increased wear life, this type of coating might be reinforced with the addition of fillers and also combining which has a metal sprayed first layer.
CORROSION AND CHEMICAL RESISTANCE
PTFE is inherently proof against attack from most chemicals and when along with other fluoropolymers like FEP and PFA greatly improves the time of the component. PTFE applied as being a surface coating will heighten the corrosion resistance with the component which enable it to be also enhanced by using primers, other pre-treatments like plating and phosphating. Stud bolts and fasteners, valves, pumps, pipe clamps and connectors all make use of these types of coatings.
ELECTRICAL PROPERTIES
PTFE has a high dielectric strength, a decreased dissipation factor, insulating as well as surface resistivity, giving protection and uses in numerous electrical applications. Our coatings may also be built to become conductive and utilized as an antistatic coating. Light fittings, connectors, cable guides and portable electrical equipment all benefit from PTFE.
ANTI-GALLING
PTFE coatings prevent galling and provides excellent bearing properties. Mating surfaces and rotating parts make use of this coating that assist provide minimal maintenance downtime.
