The main benefit of PTFE coatings (like Teflon) may be the non-stick properties of the material, meaning applications for example commercial bakeware have excellent non-stick / release properties and so are very easy to clean.
We’ve created a selection of PTFE coating systems with many different benefits to suit most applications. The function that the coating will be utilized for along with the operating conditions will define the selection of the best coating for the position.
On this blog, we explore some of the benefits in greater detail.
NON-STICK AND RELEASE
A PTFE coating put on a factor can give excellent non-stick/release properties and is also super easy to scrub. This sort of coating is also excellent at preventing both cold and hot products from permanently sticking to the substrate and for that reason is widely used from the cookware, confectionery, food processing and bakery industries. PTFE coatings will also be useful for non-stick inside the packaging, heat sealing, moulding, automotive, aerospace, chemical and pharmaceutical industries.
NON-WETTING
PTFE surfaces are hydrophobic and oleophobic, and won’t readily wet. This permits the pad to self-clean. To the semiconductor industry, this property owner vital because it allows all chemical media to run off and become collected.
TEMPERATURE RESISTANCE
PTFE coatings can service arduous application conditions involving extremes of temperature. They are able to remain stable at advanced temperatures of +260°C and for short periods at +290°C. PTFE may be used on extrusion dies and sealing of plastic/elastomers where other treatments may degrade or cause clogging of molten material. These coatings can also perform at cryogenic temperatures which enable it to 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 and it is therefore perfect for shafts, bearing surfaces, moving mechanisms, stud bolts and fasteners. For added abrasion resistance and increased wear life, such a coating can be reinforced with the addition of fillers and through combining with a metal sprayed base layer.
CORROSION AND CHEMICAL RESISTANCE
PTFE is inherently resistant against attack from most chemicals when combined with other fluoropolymers like FEP and PFA greatly increases the time of the component. PTFE applied as being a surface coating will increase the corrosion resistance with the component and can also be enhanced with the use of primers, other pre-treatments for example plating and phosphating. Stud bolts and fasteners, valves, pumps, pipe clamps and connectors all benefit from these kind of coatings.
ELECTRICAL PROPERTIES
PTFE includes a high dielectric strength, a low dissipation factor, insulating and surface resistivity, giving protection and uses in several 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 make use of PTFE.
ANTI-GALLING
PTFE coatings prevent galling and present excellent bearing properties. Mating surfaces and rotating parts take advantage of this coating which help provide minimal maintenance downtime.
