The main benefit of PTFE coatings (including Teflon) could be the non-stick properties from the material, this means applications for example commercial bakeware have excellent non-stick / release properties and are very easy to clean.
We’ve created range of PTFE coating systems with many different good things about suit most applications. The function that the coating is to be utilized for and also the operating conditions will define selecting the correct coating for the task.
In this blog, we explore a few of the benefits in great detail.
NON-STICK AND RELEASE
A PTFE coating used on a factor can give excellent non-stick/release properties and is also super easy to wash. Such a coating is additionally excellent at preventing both cold and hot products from permanently staying with the substrate and for that reason is trusted within the cookware, confectionery, food processing and bakery industries. PTFE coatings can 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 allows the pad to self-clean. For your semiconductor industry, this property is vital since it allows all chemical media to run off and stay 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 other remedies may degrade or cause clogging of molten material. These coatings can also perform at cryogenic temperatures and will remain stable at -270°C.
LOW FRICTION AND ABRASION RESISTANCE
PTFE coated surfaces reduce friction and will 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 is therefore perfect for shafts, bearing surfaces, moving mechanisms, stud bolts and fasteners. For really abrasion resistance and increased wear life, this sort of coating may be reinforced with the help of fillers through combining having a metal sprayed first layer.
CORROSION AND CHEMICAL RESISTANCE
PTFE is inherently resistant to attack from most chemicals then when joined with other fluoropolymers such as FEP and PFA greatly increases the life of the component. PTFE applied as being a surface coating will heighten the corrosion resistance in the component and will be enhanced with the aid 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 carries a high dielectric strength, a low dissipation factor, insulating and surface resistivity, giving protection and uses in several electrical applications. Our coatings can 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 provide excellent bearing properties. Mating surfaces and rotating parts benefit from this coating and help provide minimal maintenance downtime.
