The main benefit of PTFE coatings (such as Teflon) will be the non-stick properties with the material, which means applications including commercial bakeware have excellent non-stick / release properties and therefore are very easy to completely clean.
We have created a range of PTFE coating systems with many different advantages to suit most applications. The part that this coating shall be useful for and also the operating conditions will define the selection of the correct coating for the task.
On this blog, we explore a number of the benefits in great detail.
NON-STICK AND RELEASE
A PTFE coating applied to a factor gives excellent non-stick/release properties and it is super easy to scrub. Such a coating can also be excellent at preventing both hot and cold products from permanently sticking with the substrate and so is traditionally used from the cookware, confectionery, food processing and bakery industries. PTFE coatings may also be useful for non-stick from the packaging, heat sealing, moulding, automotive, aerospace, chemical and pharmaceutical industries.
NON-WETTING
PTFE surfaces are hydrophobic and oleophobic, and will not readily wet. This enables the fabric to self-clean. To the semiconductor industry, this property owner vital mainly because it allows all chemical media to perform off and become collected.
TEMPERATURE RESISTANCE
PTFE coatings can service arduous application conditions involving extremes of temperature. They are able to remain stable at advanced temperatures of +260°C as well as 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 could 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 is therefore well suited for shafts, bearing surfaces, moving mechanisms, stud bolts and fasteners. For added abrasion resistance and increased wear life, this kind of coating can be reinforced by having fillers and also by combining which has a metal sprayed lower layer.
CORROSION AND CHEMICAL RESISTANCE
PTFE is inherently resistant against attack from most chemicals when along with other fluoropolymers for example FEP and PFA greatly raises the duration of the component. PTFE applied being a surface coating will increase the corrosion resistance from the component and can also be enhanced by using primers, other pre-treatments including plating and phosphating. Stud bolts and fasteners, valves, pumps, pipe clamps and connectors all make use of most of these coatings.
ELECTRICAL PROPERTIES
PTFE includes a high dielectric strength, a low dissipation factor, insulating and also surface resistivity, giving protection and uses in many 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 reap the benefits of PTFE.
ANTI-GALLING
PTFE coatings prevent galling and provides excellent bearing properties. Mating surfaces and rotating parts reap the benefits of this coating that assist provide minimal maintenance downtime.
