Why Choose High Elastic Durable Wear-Resistant Polyurethane PU Rubber to make Parts?

Ⅰ.Production of Polyurethane Rubber Roller Parts and PU Components

The production process of polyurethane rubber roller parts and PU components mainly includes raw material preparation, formula design, mixing, molding, vulcanization, trimming, and inspection.

1. Raw Material Preparation: The main raw materials for polyurethane rubber include organic diisocyanates or polyisocyanates and dihydroxy or polyhydroxy compounds. These raw materials need to undergo strict screening and inspection to ensure their quality meets production requirements.

2. Formula Design: Based on the operating environment and performance requirements of the roller, an appropriate polyurethane rubber formula is designed. Formula design needs to consider the hardness, abrasion resistance, solvent resistance, elasticity, and other performance indicators of the roller.

3. Mixing: The raw materials in the formula are mixed in a mixer or calender to ensure they are fully blended. Temperature and time need to be controlled during the mixing process to ensure effective blending.

4. PU Molding: The mixed polyurethane rubber material is shaped into the desired roller form through an extruder or injection molding machine. Temperature and pressure need to be controlled during the molding process to ensure precision in roller size and shape.

5. Vulcanization: The molded roller undergoes vulcanization treatment to stabilize its physical and chemical properties. Temperature and time need to be controlled during the vulcanization process to ensure effective treatment.

6. Trimming: The vulcanized roller is trimmed to remove burrs and flashes, leaving a smooth and flat surface.

7. Inspection: Quality inspection is performed on the trimmed roller, including checks on appearance quality, dimensional accuracy, and physical properties, to ensure it meets usage requirements.

Ⅱ.Application of Polyurethane Rubber Roller Parts and PU Components

Due to their excellent physical and chemical properties of PU Materials, polyurethane rubber roller parts and components are widely used in multiple fields.

1. Printing Industry: Polyurethane rubber rollers are essential components in printing presses, used to transfer ink and paper media. Their soft and elastic surfaces ensure the clarity and quality of printed materials. At the same time, polyurethane rubber rollers have good solvent resistance and abrasion resistance, maintaining stable printing effects over time.

2. Medical Field: In some medical equipment, such as hemodialysis machines and blood filters, pipeline systems that can transmit fluids are required. Polyurethane rubber tubing is an ideal choice for these applications due to its good fluid flow properties and resistance to disinfectants.

3. Food Industry: In food packaging and production processes, various seals and gaskets are used to prevent product leakage or contamination. Polyurethane rubber products, with their excellent corrosion resistance and elasticity, are ideal substitutes for these critical components.

4. Machinery Industry: Polyurethane rubber rollers also have a wide range of uses in the machinery industry, such as in tape transmission systems and seals. Their outstanding abrasion resistance and elasticity make polyurethane rubber excel in these applications, providing strong support for the stable operation of machinery and equipment.

5. Automotive Industry: Polyurethane rubber also plays an important role in the automotive industry, particularly in tire and seal manufacturing. Its unique physical properties make polyurethane rubber an indispensable material in automobile manufacturing, providing strong support for vehicle safety and performance.

In addition, polyurethane rubber roller parts and components are widely used in mining, metallurgy, textiles, clothing, and other fields. The continuous expansion and deepening of these application fields have further promoted the development and growth of the polyurethane rubber roller parts and components industry.

In summary, the production and application of polyurethane rubber roller parts and components involve multiple aspects. Their excellent physical and chemical properties make them widely used in various fields. With the continuous advancement of technology and the expansion of application fields, the development prospects of the polyurethane rubber roller parts and components industry will be broader.
