The main benefit of PTFE coatings (such as Teflon) will be the non-stick properties of the material, meaning applications such as commercial bakeware have excellent non-stick / release properties and therefore are quite simple to clean.

We have designed a variety of PTFE coating systems with many different advantages to suit most applications. The part that the coating shall be employed for and also the operating conditions will define picking a the correct coating to do the job.

Within this blog, we explore a number of the benefits in more detail.

NON-STICK AND RELEASE
A PTFE coating put on a factor can give excellent non-stick/release properties and it is very easy to wash. This kind of coating can be excellent at preventing both cold and hot products from permanently adhering to the substrate and for that reason is popular from the cookware, confectionery, food processing and bakery industries. PTFE coatings are also useful for non-stick in the packaging, heat sealing, moulding, automotive, aerospace, chemical and pharmaceutical industries.

NON-WETTING
PTFE surfaces are hydrophobic and oleophobic, will not readily wet. This allows the material to self-clean. For your semiconductor industry, this rentals are vital mainly because it allows all chemical media to operate off and stay 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 and for short periods at +290°C. PTFE can be utilized on extrusion dies and sealing of plastic/elastomers where other remedies may degrade or cause clogging of molten material. These coatings also can perform at cryogenic temperatures and may remain stable at -270°C.

LOW FRICTION AND ABRASION RESISTANCE
PTFE coated surfaces reduce friction and will 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 well suited for shafts, bearing surfaces, moving mechanisms, stud bolts and fasteners. With regard to added abrasion resistance and increased wear life, this kind of coating could be reinforced by building fillers through combining which has a metal sprayed first layer.

CORROSION AND CHEMICAL RESISTANCE
PTFE is inherently resistant to attack from most chemicals then when combined with other fluoropolymers for example FEP and PFA greatly increases the duration of the component. PTFE applied like a surface coating will increase the corrosion resistance from the component and may be also enhanced with the aid 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 kinds of coatings.

ELECTRICAL PROPERTIES
PTFE features a high dielectric strength, a low dissipation factor, insulating and also surface resistivity, giving protection and uses in numerous electrical applications. Our coatings may also be made to become conductive and used 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 provides excellent bearing properties. Mating surfaces and rotating parts reap the benefits of this coating which help provide minimal maintenance downtime.
