Uliflex's employees responsible for customer relations often encounter many inquiries from customers in their daily work about the differences between domestic PU and foreign PU. After all, customers cannot distinguish between domestic PU and foreign PU just by naked eye. Many customers may have a misconception that the performance and quality of industrial belts made from domestic PU raw materials are almost the same as those made from foreign PU raw materials, and they want to reduce production costs by purchasing industrial belts made entirely from domestic materials.
It must be noted that although industrial belts made of domestic materials may appear similar to those made of foreign materials to the naked eye, there are significant differences in performance and quality. It can be said that the performance and quality of industrial belts made entirely of foreign materials are superior to those made entirely of domestic materials.
The reason for this conclusion is that polyurethane (PU) industrial belts, as key components in modern industrial transmission and conveying systems, have performance differences mainly due to differences in material formulations, production processes, and quality standards.
The following are the main differences between PU industrial belt materials at home and abroad：
1.Differences in raw materials and formulas
Domestic PU: Domestic PU belts mainly use domestically produced polyurethane raw materials.
Foreign PU: most international brands use imported raw materials that have been specially treated. Foreign high-end PU materials are usually added with anti-aging agent and reinforcement fiber with patent formula, so that the products have better wear resistance and tear resistance.
Although domestic PU has gradually narrowed the gap in material formulation through technology introduction and independent research and development in recent years, overall, the performance of foreign PU is still ahead of domestic PU.
Domestic PU: Some leading domestic enterprises have introduced technologies similar to foreign ones, but there is still a gap in the overall industry level, especially in high-precision application fields such as high-speed transmission (80 meters/second).
Foreign PU: The production process of PU belts in foreign countries is more precise, such as the hot press molding technology adopted by German and Japanese companies, which can ensure the consistency of belt thickness and length with smaller tolerances.
Foreign products are more mature in steel core reinforcement technology and the combination process of polyurethane and skeleton materials.
3.PU Comparison of performance indicators
· Wear resistance: The wear resistance of international brand PU belts can reach 8 times that of domestic ordinary products.
· Chemical resistance: Imported PU has stronger resistance to acid, alkali, and oil, especially suitable for special environments such as food and medicine.
· Temperature range: High end imported PU has a wider working temperature range (-25 ° C to+80 ° C, and can reach up to 110 ° C instantly).
· Hygiene standards: Both domestic and international food grade PU belts have met FDA standards, but imported products have better stability in long-term use.
Domestic PU: Domestic PU belts are more commonly used in mid-range manufacturing industries, such as ordinary conveyor belts, packaging machinery, etc.
Foreign PU: Imported products dominate the high-end market, such as precision instrument drives, medical equipment, high-speed automated production lines, etc.
In the new energy industry (such as lithium batteries and photovoltaic equipment), domestic PU elastic bands have gained certain competitiveness and can meet special needs such as silicon wafer testing and coating equipment.
5.Market Status and Development Trends
China is the world's largest producer of PU belts, with a market size of approximately 320 million US dollars in 2023, accounting for 37.6% of the global market. Domestic enterprises have continued to grow in exports due to their cost-effectiveness advantage (with a year-on-year increase of 12% in export value in 2023).
It is expected that by 2030, the Chinese PU belt market will maintain an annual growth rate of over 6%, gradually penetrating into high-end fields through technological innovation. International brands maintain a leading position in the research and development of environmentally friendly and bio based polyurethane materials.
The production process of Uliflex industrial belts is consistent with the production process of internationally renowned industrial belts,
The material is indeed high-quality imported from abroad, with a much higher cost-effectiveness than some internationally renowned industrial belts.
The key is that Uliflex has always been a partner of the most well-known international industrial belt company, and they purchase industrial belts from Uliflex every year. The quality and performance of Uliflex industrial belts are recognized by international major brand industrial belt companies (our competitors).
No matter how the market environment changes, Uliflex has always adhered to the path of independent branding, producing high-quality products and providing customers with the best solutions for industrial belt use.
We refuse to use inferior materials to reduce costs, do not produce products that harm customer interests, and do not engage in behavior that harms the Uliflex brand. Uliflex is a scholarly professional enterprise with its own values and over 20 years of deep cultivation in the field of industrial belts.
