The advantage of PTFE coatings (for example Teflon) will be the non-stick properties from the material, which means applications like commercial bakeware have excellent non-stick / release properties and they are quite simple to clean.

We now have created a selection of PTFE coating systems with many benefits to suit most applications. The part that the coating is to be employed for and also the operating conditions will define selecting the proper coating for the job.

On this blog, we explore many of the benefits in depth.

NON-STICK AND RELEASE
A PTFE coating put on an important part will offer excellent non-stick/release properties and is a breeze to clean. This sort of coating is also excellent at preventing both hot products from permanently sticking with the substrate and so is popular inside the cookware, confectionery, food processing and bakery industries. PTFE coatings may also be employed for non-stick within the packaging, heat sealing, moulding, automotive, aerospace, chemical and pharmaceutical industries.

NON-WETTING
PTFE surfaces are hydrophobic and oleophobic, will not readily wet. This permits the fabric to self-clean. For your semiconductor industry, this residence is vital since 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’re able to remain stable at advanced temperatures of +260°C as well as for short periods at +290°C. PTFE can be utilized 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 and can remain stable at -270°C.

LOW FRICTION AND ABRASION RESISTANCE
PTFE coated surfaces reduce friction and can achieve really 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 suitable 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 through combining using a metal sprayed first layer.

CORROSION AND CHEMICAL RESISTANCE
PTFE is inherently resistant against attack from most chemicals so when combined with other fluoropolymers including FEP and PFA greatly enhances the life of the component. PTFE applied being a surface coating will raise the corrosion resistance with the component and will 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 take advantage of these kind of coatings.

ELECTRICAL PROPERTIES
PTFE features a high dielectric strength, a low dissipation factor, insulating as well as surface resistivity, giving protection and uses in numerous electrical applications. Our coatings may also be created to become conductive and utilized as an antistatic coating. Light fittings, connectors, cable guides and portable electrical equipment all take advantage of PTFE.

ANTI-GALLING
PTFE coatings prevent galling and provides excellent bearing properties. Mating surfaces and rotating parts reap the benefits of this coating that assist provide minimal maintenance downtime.
