The main benefit of PTFE coatings (like Teflon) could be the non-stick properties in the material, meaning applications for example commercial bakeware have excellent non-stick / release properties and are very easy to scrub.

We’ve created variety of PTFE coating systems with lots of advantages of suit most applications. The function that the coating will be utilized for and also the operating conditions will define the selection of the correct coating to do the job.

On this blog, we explore many of the benefits in great detail.

NON-STICK AND RELEASE
A PTFE coating used on an important part will give excellent non-stick/release properties and is also very easy to scrub. Such a coating can be excellent at preventing both cold and hot products from permanently staying with the substrate and therefore is widely used within the cookware, confectionery, food processing and bakery industries. PTFE coatings are also used for non-stick inside the packaging, heat sealing, moulding, automotive, aerospace, chemical and pharmaceutical industries.

NON-WETTING
PTFE surfaces are hydrophobic and oleophobic, will not readily wet. This gives the fabric to self-clean. For the semiconductor industry, this property owner vital because it allows all chemical media to run off and turn into 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 may 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 will remain stable at -270°C.

LOW FRICTION AND ABRASION RESISTANCE
PTFE coated surfaces reduce friction which enable it to 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 ideal for shafts, bearing surfaces, moving mechanisms, stud bolts and fasteners. For additional abrasion resistance and increased wear life, this sort of coating can be reinforced by building fillers through combining which has a metal sprayed lower layer.

CORROSION AND CHEMICAL RESISTANCE
PTFE is inherently proof against attack from most chemicals then when coupled with other fluoropolymers like FEP and PFA greatly raises the lifetime of the component. PTFE applied like a surface coating will heighten the corrosion resistance of the component which enable it to even be enhanced with the aid of primers, other pre-treatments for example plating and phosphating. Stud bolts and fasteners, valves, pumps, pipe clamps and connectors all take advantage of these kinds of coatings.

ELECTRICAL PROPERTIES
PTFE includes a high dielectric strength, a minimal dissipation factor, insulating and surface resistivity, giving protection and uses in lots of electrical applications. Our coatings can even be built 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 provide excellent bearing properties. Mating surfaces and rotating parts make use of this coating which help provide minimal maintenance downtime.
