Thermoplastic powder coatings are derived from four major subtypes i.e. Polyethylene, Polypropylene, Nylon, Polyvinyl powders:

• Polyehylene powders were the first thermoplastic powder coating offered to the industry. Polyethylene powders provide coatings of excellent chemical resistance & toughness with outstanding electrical insulation properties.
• Polypropylene powders offer many of the useful properties it has as a plastic material. Because natural polypropylene is so inert it shows little tendency to adhere to metal or other substrates. This characteristic make it necessary to chemically modify the natural polypropylene when it is used as a surface coating powder, so that adhesion of the coating to the substrate can be obtained.
• Nylon powders are superior in performance with excellent abrasion resistance & Impact resistance. Most interesting use of nylon powder coating is in the field of mechanical design.
• Polyvinyl powders are powders with superior exterior durability. They bond well to most metal substrates when applied over a suitable primer. They are also FDA approved for food contact & can be used for a number of similar applications. This powder is also a great electrical insulator.
