Relying on the domestic market, Letone products are advertised in offices all over the country and on the Internet to expand service areas. Every year, the company invests heavily in the development of new projects such as industrial pipes, rubber and plastic pipes, etc., and continuously improves the quality of products. With its own strength and the achievements of college cooperation, it has established a cooperative relationship with Qingdao University in terms of R&D technology. In addition to close cooperation with many scientific research institutions, it also cooperates with many companies in Germany and the United States to improve products and expand applications.

Luohe Letone Technology Co., Ltd. processes 15,000 tons of rubber annually, produces 40 million meters of hydraulic hoses, petrochemical and other industrial hoses, and 20 million rubber seals and related products. It is expected that after the project is fully put into operation in 2024, the production and sales volume of various pipes will reach 120 million meters, the production and sales volume of compound rubber will reach 35,000 tons, and the number of gaskets and related products produced and sold will increase to 10 million pieces. 

The output of the device will reach 50 million pieces, and the output value is expected to exceed 2.5 billion yuan. LT1306 UPE super wear-resistant concrete conveying hose is suitable for conveying concrete, gypsum, grouting, sand and gypsum. The inner rubber layer is made of ultra-high molecular polyethylene (UPE) and styrene-butadiene rubber (SBR) & natural rubber (NR) synthesis The rubber and UPE material are imported from Germany, the molecular weight is 5 million times that of the domestic one, and has ultra-high wear resistance; the reinforcing layer is made of multi-layer spiral steel wire, which can well protect the pipe body; the outer layer of the pipe is also made of ultra-resistant Grinding UPE material can greatly improve the service life of the pipe. If the carbon-free insulating rubber hose requires equipment with a high insulation coefficient, if the wrong pipe is used, a safety accident will occur, and the electrical breakdown will be serious. In particular, there are thick copper wires and copper rods in the pipeline. Generally, the carbon-free insulating hose for small furnaces in steel mills requires a low insulation coefficient.

Letone has 15 years of experience in producing carbon-free insulating hoses, which are not only insulated but also have a high degree of heat resistance, heat-resistant water and hot air aging. The lifespan of the carbon-free insulating hose is 3.4 times longer than that of the ordinary hose. Greatly reduce the cost of the enterprise and reduce the secondary pollution to the environment.Protective wax is a mixture of saturated linear hydrocarbon refined wax and saturated isomerized hydrocarbon microcrystalline wax. When the amount in the rubber compound exceeds its solubility in rubber, it migrates to the surface of rubber products after vulcanization. A physical protective film that effectively prevents ozone cracking.

Chemical antioxidants are often used in acid and alkali resistant hoses. Among them, the solubility of chemical antiozonants in wax is higher than that in rubber, and the migration speed of wax in rubber is faster than that of chemical antiozonants. Diffusion, improve the ozone crack resistance of acid and alkali resistant hoses under dynamic and static conditions. High-pressure hoses are widely used in 1. Textile, chemical fiber, printing and dyeing, petroleum, chemical industry, steel, gas, air conditioning, automobile, fire protection, urban water supply, construction, metallurgy and petrochemical fields; 2. Transporting high-temperature gas, hot oil and other high-temperature media. (For example: hot steam, heat transfer oil, etc.); 3. Transport low temperature or ultra-low temperature medium. (For example: liquid atmosphere) 4. Transport water, steam, oil and other media in high temperature environment. (For example: water vapor system and hydraulic system in coking, steelmaking, continuous casting equipment).
