The advantage of PTFE coatings (such as Teflon) may be the non-stick properties from the material, which means applications for example commercial bakeware have excellent non-stick / release properties and they are very easy to wash.
We have created array of PTFE coating systems with many different good things about suit most applications. The function how the coating will be employed for and also the operating conditions will define selecting the proper coating to do the job.
In this blog, we explore a few of the benefits in great detail.
NON-STICK AND RELEASE
A PTFE coating applied to an element will give excellent non-stick/release properties which is quite simple to completely clean. Such a coating is also excellent at preventing both cold and hot products from permanently staying with 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 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 gives the information to self-clean. For your semiconductor industry, this property owner vital since it allows all chemical media to own off and stay collected.
TEMPERATURE RESISTANCE
PTFE coatings can service arduous application conditions involving extremes of temperature. They can 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 other treatments 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 minimal coefficients of friction, typically from about 0.04 to 0.15. Where oils and grease evaporate at elevated temperatures PTFE remains which is therefore perfect for shafts, bearing surfaces, moving mechanisms, stud bolts and fasteners. For additional abrasion resistance and increased wear life, this type of coating may be reinforced with the help of fillers and also combining having a metal sprayed lower layer.
CORROSION AND CHEMICAL RESISTANCE
PTFE is inherently resistant against attack from most chemicals and when combined with other fluoropolymers like FEP and PFA greatly raises the duration of the component. PTFE applied as being a surface coating will raise the corrosion resistance of the component and may be also enhanced if you use primers, other pre-treatments such as plating and phosphating. Stud bolts and fasteners, valves, pumps, pipe clamps and connectors all reap the benefits of most of these coatings.
ELECTRICAL PROPERTIES
PTFE features a high dielectric strength, the lowest dissipation factor, insulating and high surface resistivity, giving protection and uses in numerous electrical applications. Our coatings can also be made 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 present excellent bearing properties. Mating surfaces and rotating parts make use of this coating and help provide minimal maintenance downtime.
