Polymers cost 1/3 less than metals and outperforms metals in many aggressive environments. They weigh much less than metals and have same strengths as metals. These new Polymers are stable up to 300 C. They can be used to make all common processing equipment like silos, hammer mills, mixers, conditioners, coaters, dryers, conveyors, elevators, coolers, etc. They are insulators so it is more useful in making dryers as separate insulation is not required. Even metallic bearings, seals, blades, etc can be built of polymer as it has excellent wear resistance without lubrication. Even have chemical resistance to many solvents.
One of the polymers on the market today is VICTREX PEEK conforms to FDA requirements and may be safely used for food contact. Because of its ultimate combination of properties, it is a cost-effective solution to large stainless steel surfaces, acetal and nylon in food processing applications. Due to its ability to eliminate problems such as frequent maintenance of components metal contamination and flaking deterioration due to steam and harsh chemicals lubrication contamination and staining, this polymer is an ideal choice.
* Offers excellent wear resistance coupled with a low coefficient of friction
* Compliant with the requirements of FDA regulation for use in food contact applications
* Ideal for wide ranging temperatures found in food and beverage processing and cleaning equipment
* Insoluble in all common solvents and has excellent resistance to acids, bases, salts and steam
* Substantially lower moisture absorption than nylons and other polymers
* Outperforms metals in many aggressive environments
* Non-galling nature allows for use in aggressive wear applications
* Coatings made offer scratch-resistance and long-life durability.
