Coating rolls with plastic is a process used in the industry to provide machine rollers with a wear-resistant plastic coating. This coating enhances the performance of the rolls and extends their lifespan, making them more suitable for use in various applications, such as in the steel and paper industry, printing, textile production, and more.
Polyurethane (PU)
Polyurethane is a versatile plastic material that is popular for coating rollers due to its excellent wear resistance, tear resistance, and flexibility. It is resistant to oils, fats, and many chemicals, making it suitable for applications where contact with such substances may occur. The hardness of polyurethane coating can vary, from soft (for grip) to hard (for wear resistance), depending on the application.
Polyamide (Nylon)
Polyamide, also known as nylon, is another commonly used material for coating rollers. It is known for its wear resistance and low coefficient of friction. Nylon coating is suitable for applications where high loads and friction are involved, such as in the textile industry and on conveyor belts. It can also have good chemical resistance, depending on the specific type of nylon used.
Teflon (PTFE)
Teflon, also known as polytetrafluoroethylene (PTFE), is renowned for its excellent non-stick properties, low coefficient of friction, and high temperature resistance. It is often used in applications where high temperatures, such as in the food industry, and non-stick properties are important. PTFE coating is also valued for its chemical inertness, meaning it is resistant to most chemicals.
