What is the function and performance of polyurethane coated bearings

In today's building materials industry, more and more polyurethanes can be seen. Polyurethane is a very versatile material, but many people do not understand what polyurethane is and what effect it has. In response to this situation, let me briefly introduce to us below. What are the functions and performances of polyurethane coated bearings?

The full name of polyurethane is polyurethane, which is a general term for macromolecular structural compounds that contain a large number of repetitive amino groups on the main chain to generate formate groups. It has a wide range of uses. It can be used in hotels, building materials, automobile factories, coal plants, cement plants, apartments, villas, landscape design and beautification, colorful stone art, parks, etc., by replacing traditional rubber, plastic, nylon, etc. Rubber-coated bearing rollers

The effect of polyurethane:

It can be used in the manufacture of plastics, rubber, fibers, rigid and soft foams, adhesives and coatings, and it is also widely used in the day.

1. Polyurethane foam materials: divided into rigid polyurethane foam, semi-rigid polyurethane foam and soft polyurethane foam metal materials. It can be mainly used for building structural thermal insulation materials, thermal insulation engineering materials, daily school supplies, and corporate transportation management tools.

2. Polyurethane elastomer: Polyurethane elastomer has the advantages of good tensile strength, tear resistance, impact resistance, abrasion resistance, water resistance and oil resistance. Mainly used as a coating material.

3. Polyurethane waterproof material: It is very convenient to use and can be mixed on site. After coating, it is moisture-cured at room temperature and can be seamless. The thermodynamic theory of polymer elasticity and a waterproof layer with good functions. It is easy to fix it after damage. Generally used as paving materials, runways, park ground materials, etc.

4. Polyurethane coating: a coating film with strong adhesion, excellent wear resistance, water resistance and chemical resistance. Mainly used in furniture coatings, industrial coatings, etc.

5. Polyurethane adhesive: It can be analyzed to adjust the function of the cured product by adjusting the ratio of active isocyanate and polyol together, so that it can achieve a high degree of adhesion to the substrate, excellent water resistance, and oil resistance. And chemical resistance. Mainly used in product packaging, construction, wood and other industries.
