Crusher Enterprises Form Core Competence to High-end Technology Development
Phthalic Anhydride Polyester Polyol
Polyester Polyol is a type of polyol that is derived from the reaction between a polyol (such as glycerol or ethylene glycol) and a dicarboxylic acid (such as adipic acid or phthalic anhydride). It is commonly used as a raw material in the production of polyurethane foams, coatings, adhesives, and elastomers.
Polyester polyols have several advantages over other types of polyols. They have good chemical resistance, mechanical properties, and thermal stability. They also have low toxicity and are environmentally friendly. Additionally, polyester polyols can be easily modified to achieve desired properties, such as increased flexibility or flame retardancy.
Polyester polyols are typically liquid at room temperature and have a high molecular weight. They can be further reacted with isocyanates to form polyurethane materials, which have a wide range of applications in various industries, including automotive, construction, and furniture.
Polyurethane packaging foam is a type of foam material that is commonly used for packaging and cushioning products during shipping and transportation. It is made from polyurethane, a polymer that is created through a chemical reaction between polyols and diisocyanates.
Polyurethane packaging foam is known for its excellent shock absorption and cushioning properties. It is lightweight and can be easily molded into various shapes and sizes to fit the specific needs of the product being packaged. The foam is also resistant to moisture, chemicals, and oil, making it suitable for protecting products in various environments.
There are two main types of polyurethane packaging foam: flexible foam and rigid foam. Flexible foam is soft and pliable, providing cushioning and protection for fragile items. Rigid foam, on the other hand, is more dense and firm, providing structural support and protection for heavier items.
Polyurethane packaging foam can be custom-made to meet specific requirements, such as density, firmness, and compression strength. It is widely used in industries such as electronics, automotive, furniture, and medical equipment, where protection and safety during transportation are crucial.
Overall, polyurethane packaging foam is a versatile and effective material for protecting products during shipping and transportation, ensuring that they arrive at their destination in good condition.

Green crusher equipment has also become the design concept of current production companies in accordance with the requirements of the times. Environmental protection and energy conservation have been the topic of current stereotypes. Under the influence of the “whoever pollutes and who govern†mechanism, the selection of efficient, high-productivity equipment has saved companies a lot of pollution control costs, thus contributing to the nation’s green building. Since the 1980s, China’s economic construction has gradually started to develop rapidly. No matter which industry, including China’s railway construction, highway construction, and real estate development, mining and water conservancy industries are developing rapidly, and these industries The development led to an economic industrial chain. For example, repairing highways, repairing railways, and building uses cement, gravel, sandstone, etc., which ushered in the peak period of rapid development of mines and gravel industries, and the mines The crushing equipment is used in the production of sand and gravel, so the development of the crushing machinery industry has gradually entered a peak period. This ring-and-loop mechanism has led to the development of infrastructure and the development of the sand and crusher industry.
At present, the domestic leading enterprises are still relatively weak compared with the strength of transnational corporations, and those expert firms that concentrate their efforts on forming core competitiveness in some products and markets and are led by gross profit are more likely to survive fierce competition. Down. Veken is working hard to break the leader in the industry and will not be afraid of the hardships ahead, and will strive to leave a footprint in the history of the crusher! In the 21st century, China has become a major country in mining machinery manufacturing and has attracted worldwide attention. However, we are not a strong country in mining machinery manufacturing. There are not many high-end products manufactured by our country with independent intellectual property rights. Veken Heavy Industries will, through independent innovation, develop digital, intelligent, ecological, and humane mining machinery, achieve major equipment, high-end packages, and make greater contributions to China's economic and social development.
