Information It Is Advisable To Be Informed About PTFE Coating Advantages

The main benefit of PTFE coatings (such as Teflon) may be the non-stick properties with the material, which means applications like commercial bakeware have excellent non-stick / release properties and they are quite simple to scrub.

We’ve got created a variety of PTFE coating systems with many different advantages of suit most applications. The part that the coating is to be employed for as well as the operating conditions will define selecting the correct coating to do the job.

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

NON-STICK AND RELEASE
A PTFE coating placed on an important part gives excellent non-stick/release properties and is very easy to clean. This type of coating is additionally excellent at preventing both cold and hot products from permanently adhering to the substrate and so is widely used from the cookware, confectionery, food processing and bakery industries. PTFE coatings can also be used for non-stick within 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 enables the pad to self-clean. For your semiconductor industry, this property is vital since it allows all chemical media to own off and become 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 short periods at +290°C. PTFE works extremely well on extrusion dies and sealing of plastic/elastomers where anything else 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 which enable it to achieve minimal coefficients of friction, typically from about 0.04 to 0.15. Where oils and grease evaporate at elevated temperatures PTFE remains and is therefore well suited for shafts, bearing surfaces, moving mechanisms, stud bolts and fasteners. For really abrasion resistance and increased wear life, such a coating may be reinforced with the addition of fillers and also by combining having a metal sprayed base layer.

CORROSION AND CHEMICAL RESISTANCE
PTFE is inherently resistant against attack from most chemicals and when combined with other fluoropolymers including FEP and PFA greatly increases the lifetime of the component. PTFE applied as a surface coating will increase the corrosion resistance of the component which enable it to be also enhanced with the use of primers, other pre-treatments like plating and phosphating. Stud bolts and fasteners, valves, pumps, pipe clamps and connectors all take advantage of these types of coatings.

ELECTRICAL PROPERTIES
PTFE includes a high dielectric strength, the lowest dissipation factor, insulating and surface resistivity, giving protection and uses in lots of electrical applications. Our coatings can also be built to become conductive and used as an antistatic coating. Light fittings, connectors, cable guides and portable electrical equipment all reap the benefits of PTFE.

ANTI-GALLING
PTFE coatings prevent galling and provide excellent bearing properties. Mating surfaces and rotating parts take advantage of this coating and help provide minimal maintenance downtime.
