Nonstick coatings are providing a service that is continuing to expand globally. Today, finishing companies providing nonstick coating services offer numerous options. The three most common ones are:
- Polytetrafluoroethylene or PTFE coatings
- Silicone coatings
- Sol-gel or ceramic coatings
However, the most popular, and the basis for the trade-marked Teflon, are those coatings using PTFE. In the United States, consumption of this coating accounts for approximately 15.5% of the global market.
Applications
The non-toxic, nonstick, plastic polymers comprising PTFE are in high demand among certain industries. As to be expected, they feature prominently as a protective, transparent, and highly functional coating of various cookware and baking utensils e.g., pots, frying pans, cookies sheets. However, PTFE is offered by companies to provide nonstick coating services for other industries and their products including:
- Cables
- Carburetor parts
- Curling irons and flat irons
- Medical devices
- Pet toys and dishes
- Semiconductors
- Windshield wipers
Properties
Further increasing the attraction of PTFE are its properties. By coating the surface of a component, they enhance and provide the following:
- Durability
- Exceptional corrosion resistance
- Remarkable abrasion, electrical and chemical resistance
- Friction reduction
- Low surface tension
- Resistance to galling
- High and low-temperature tolerance
- Versatile – can be applied to diverse metals, some plastics, and even certain rubbers
Components coated with certain types of PTFE also may offer weather-resistant and water-repellent qualities.
Nonstick Coating Services: Choosing PTFE
Fluoropolymer coatings have long been recognized as providing nonstick coating services to the cooking and baking utensils’ industries. However, its utility does not end there. It has become a favorite tool for providing the essential qualities required for products in many industries – including aerospace, automotive, marine, medical, pharmaceutical, and heavy industrial equipment and machinery. Its durability, superior corrosion resistance, longevity, and high-temperature tolerance are good enough reasons to make it popular now and into the future.
