Teflon is a very popular coating for steel belts.
This is available in a variety of grades.
The most frequently specified is TFE which has the antistick properties generally associated with Teflon.
The FEP version also has important anticorrosion properties and is ideal for low temperature applications.
For food processing applications Silverstone is normally recommended.
Teflon S is a very hard coating with enhanced abrasion resistance.
Teflon coatings can be specified in a variety of colours.
Other standard coatings available include silicone, silicone rubber, polyurethane and neoprene.
Any other specific requirements can be discussed directly with Belt Technologies.
The thickness of a surface treatment can be as little as 0.025mm, depending on the coating to be applied and method of application.
With polyurethane and neoprene, the surface can be either uniform or provided with pockets to assist in the transportation of small components.
Vacuum holes can also be combined with pockets to ensure the positive orientation and retention of delicate parts.
Coatings are normally applied to the top, working surface of belts.
However they can also be applied to the ID of the steel belts or to complementary pulleys in order to change surface hardness, thus providing wear resistance or altering the coefficient of friction between belt and pulley.
