The main benefit of PTFE coatings (including Teflon) is the non-stick properties in the material, which suggests applications like commercial bakeware have excellent non-stick / release properties and are a breeze to wash.
We’ve designed a array of PTFE coating systems with lots of advantages to suit most applications. The function that the coating is usually to be employed for and also the operating conditions will define selecting the correct coating to do the job.
On this blog, we explore many of the benefits in greater detail.
NON-STICK AND RELEASE
A PTFE coating put on a factor will offer excellent non-stick/release properties and is also quite simple to completely clean. This kind of coating can also be excellent at preventing both hot and cold products from permanently staying with the substrate and thus is traditionally used within 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 does not readily wet. This gives the fabric to self-clean. To the semiconductor industry, this residence is vital as it allows all chemical media to perform 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 and 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 can also perform at cryogenic temperatures and may remain stable at -270°C.
LOW FRICTION AND ABRASION RESISTANCE
PTFE coated surfaces reduce friction and can achieve very 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 perfect for shafts, bearing surfaces, moving mechanisms, stud bolts and fasteners. With regard to added abrasion resistance and increased wear life, this sort of coating can be reinforced by having fillers and also combining using a metal sprayed lower layer.
CORROSION AND CHEMICAL RESISTANCE
PTFE is inherently resistance against attack from most chemicals then when along with other fluoropolymers such as FEP and PFA greatly enhances the duration of the component. PTFE applied as being a surface coating will heighten the corrosion resistance from the component and will be also enhanced by using primers, other pre-treatments including plating and phosphating. Stud bolts and fasteners, valves, pumps, pipe clamps and connectors all reap the benefits of these kind of coatings.
ELECTRICAL PROPERTIES
PTFE includes a high dielectric strength, a decreased dissipation factor, insulating and high surface resistivity, giving protection and uses in lots of electrical applications. Our coatings can even be designed 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 provides excellent bearing properties. Mating surfaces and rotating parts reap the benefits of this coating and help provide minimal maintenance downtime.
