What types of coatings can be applied to industrial rollers?
Industrial rollers can be coated in various ways and the choice of coating depends on factors such as the roller's intended application, the materials it will come into contact with, and the desired properties (e.g., wear resistance, chemical resistance, non-stick properties), and environmental conditions.
Here are some common types of coatings used by Hannecard for industrial rollers:
Rubber Coatings:
Rubber coatings find use in a wide range of industries and applications due to their combination of properties, including flexibility, resilience and durability. The specific type of rubber and formulation can be tailored to meet the requirements of each application.
Types of rubber:
Nitrile Rubber: Provides good resistance to oil and grease, making it suitable for printing, laminating, and conveyor rollers.
Neoprene Rubber: Offers excellent resistance to weathering, abrasion, and chemicals, making it suitable for various industrial applications.
EPDM Rubber: Known for its excellent weather resistance, EPDM is often used for outdoor rollers.
Silicone Rubber: Has high-temperature resistance and is used in applications involving extreme heat or where non-stick properties are required.
Urethane Rubber: Provides exceptional abrasion resistance and load-bearing capabilities.
Polyurethane Coatings:
Polyurethane coatings are popular for their abrasion resistance and versatility. They can be customized in terms of hardness (from 10 Shore A to 70 shore D) and flexibility to suit different applications.
Metal Coatings:
Chrome Plating: Provides a hard, corrosion-resistant surface, commonly used in the printing and packaging industries.
Nickel Plating: Offers corrosion resistance and a smooth surface finish.
Tungsten Carbide Coating: Provides excellent wear resistance and is used in high-wear applications like mining and metal processing.
Ceramic Coatings:
Ceramic coatings are used in high-temperature and wear-resistant applications, such as rollers in glass and steel industries.
Teflon (PTFE) Coatings:
PTFE coatings are known for their non-stick properties and chemical resistance. They are commonly used in food processing, printing, and packaging applications.
The choice of coating depends on the function of the roll, the materials it will handle, the environmental conditions and of course the desired performance characteristics. It's important to consult with Hannecard's coating experts to select the most appropriate coating for your specific industrial roll application.
