The advantage of PTFE coatings (for example Teflon) may be the non-stick properties of the material, which suggests applications for example commercial bakeware have excellent non-stick / release properties and so are a breeze to scrub.

We have created a variety of PTFE coating systems with lots of advantages of suit most applications. The function how the coating is to be used for along with the operating conditions will define picking a the right coating for the job.

On this blog, we explore a few of the benefits in more detail.

NON-STICK AND RELEASE
A PTFE coating used on a component will give excellent non-stick/release properties and is also quite simple to clean. This kind of coating is additionally excellent at preventing both hot and cold products from permanently sticking to the substrate and so is traditionally used in the cookware, confectionery, food processing and bakery industries. PTFE coatings are also utilized 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 rentals are vital since 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 could remain stable at advanced temperatures of +260°C as well as 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 minimal 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 ideal for shafts, bearing surfaces, moving mechanisms, stud bolts and fasteners. For really abrasion resistance and increased wear life, this type of coating can be reinforced with the help of fillers and also by combining having a metal sprayed base layer.

CORROSION AND CHEMICAL RESISTANCE
PTFE is inherently resistant against attack from most chemicals then when joined with other fluoropolymers for example FEP and PFA greatly increases the lifetime of the component. PTFE applied like a surface coating will heighten the corrosion resistance in the component and may be also enhanced with the use of primers, other pre-treatments such as plating and phosphating. Stud bolts and fasteners, valves, pumps, pipe clamps and connectors all make use of these kind of coatings.

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