The main benefit of PTFE coatings (such as Teflon) will be the non-stick properties of the material, which means applications for example commercial bakeware have excellent non-stick / release properties and are super easy to clean.
We’ve created a range of PTFE coating systems with many different advantages of suit most applications. The part that the coating is to be employed for along with the operating conditions will define picking a the right coating to do the job.
Within this blog, we explore some of the benefits in greater detail.
NON-STICK AND RELEASE
A PTFE coating used on an element will offer excellent non-stick/release properties and is also very easy to clean. Such a coating is additionally excellent at preventing both cold and warm products from permanently sticking to the substrate and for that reason is trusted inside the cookware, confectionery, food processing and bakery industries. PTFE coatings will also be useful for non-stick in the packaging, heat sealing, moulding, automotive, aerospace, chemical and pharmaceutical industries.
NON-WETTING
PTFE surfaces are hydrophobic and oleophobic, and does not readily wet. This allows the information to self-clean. For that semiconductor industry, this residence is vital since 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 as well as for short periods at +290°C. PTFE can be used on extrusion dies and sealing of plastic/elastomers where anything else may degrade or cause clogging of molten material. These coatings also can perform at cryogenic temperatures and will remain stable at -270°C.
LOW FRICTION AND ABRASION RESISTANCE
PTFE coated surfaces reduce friction and will 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 also therefore ideal for shafts, bearing surfaces, moving mechanisms, stud bolts and fasteners. For added abrasion resistance and increased wear life, this sort of coating could be reinforced with the help of fillers and also by combining having a metal sprayed first layer.
CORROSION AND CHEMICAL RESISTANCE
PTFE is inherently resistant to attack from most chemicals so when joined with other fluoropolymers like FEP and PFA greatly improves the duration of the component. PTFE applied as a surface coating will increase the corrosion resistance of the component which enable it to even be enhanced with the use of primers, other pre-treatments such as plating and phosphating. Stud bolts and fasteners, valves, pumps, pipe clamps and connectors all make use of these kinds of coatings.
ELECTRICAL PROPERTIES
PTFE features a high dielectric strength, a decreased dissipation factor, insulating and surface resistivity, giving protection and uses in many electrical applications. Our coatings can also be made to become conductive and used as an antistatic coating. Light fittings, connectors, cable guides and portable electrical equipment all benefit from PTFE.
ANTI-GALLING
PTFE coatings prevent galling and present excellent bearing properties. Mating surfaces and rotating parts take advantage of this coating that assist provide minimal maintenance downtime.
