5mm Thick Black Polyurethane Sheet

The production process of 5mm thick black polyurethane sheet mainly involves the following steps:
1. Selection of raw materials: There are two basic types of raw materials used for polyurethane boards - MDI type and TDI type. High quality raw materials need to be selected during the production process to ensure the stability of product quality.
2. Preparation of mixture: Mix the raw materials together according to the required hardness, density, and other physical properties.
3. Molding: Inject the mixture into the molding mold and form the required plates through high-temperature and high-pressure molding.
4. Post processing: Clean, deburr, remove dust, heat and other subsequent processes on the formed plates to ensure that the product quality meets customer requirements.
The following points need to be noted during the production process:
1. Pay attention to the quality and ratio of raw materials, for example, inaccurate ratios can affect molding and properties;
2. Strictly comply with the requirements of national standards to ensure product quality;
3. The production workshop should be kept clean and hygienic, and equipment maintenance and upkeep should be carried out regularly to ensure the stability and production efficiency of the equipment.
5mm thick black polyurethane sheets are generally used in the following situations:
1. Making molds and mold gaskets;
2. Used for manufacturing clean room equipment and pressure filtration equipment;
3. It can be used to coat rubber or plastic parts during the manufacturing process to enhance their protective properties.
During use, the following points should be noted:
1. Before use, check to ensure that its quality is intact and undamaged;
2. Avoid using in environments with high temperatures, flames, or other conditions that may cause fires;
3. During use, attention should be paid to avoiding collisions and impacts to prevent damage to the polyurethane board;
4. If used in low ambient temperatures, it may cause polyurethane to harden and affect its properties, and protection should be taken into account.
We have been committed to the production and research and development of polyurethane sheets for nearly 20 years. Different specifications of polyurethane sheets will use different production processes, and different raw materials will be used in different usage scenarios. We use raw materials produced by well-known raw material manufacturers, with a professional technical team and production team as guarantees, and a comprehensive after-sales service as a backing. Moreover, as a manufacturer, we eliminate the need for intermediaries, allowing our products to have reasonable prices while ensuring quality. It has saved you a lot of costs.

These polyurethane sheets are manufactured from thermosetting material, and therefore they cannot be reformed or reheated but they can be machined. Polyurethane components from these bases outperform products manufactured from rubber and other traditional materials.

Is PU the same as polyester?

Because polyester has a much higher solid content than polyurethane, polyester's surface is stronger making it less vulnerable to scratching and chemical cleaning. However, polyurethane is more flexible than polyester making it suitable for applications where flexibility is important

Is PU better than rubber?

Unlike rubber, polyurethane offers higher load-bearing capacity, better compression set, and superior tolerance to greases, oils, oxygen, and ozone.
