The R&D team of Letong Technology broke the industry convention and developed the King Hose among the chemical hoses--Letong Technology PTFE multifunctional hose. The hose uses PTFE as the inner material of the hose (PTFE, also known as polytetrafluoroethylene, is a high molecular polymer known as the "King of Plastics", with its excellent chemical stability, corrosion resistance, high Low temperature, electrical insulation, non-stick surface, etc. solve many problems in petroleum, chemical, electrical, pharmaceutical and other industries.)
The combination of PTFE and rubber hose makes it capable of transporting strong oxidants, reducing agents, strong acids and various organic solvents (except molten alkali metals, fluorinated media and sodium hydroxide above 220°C) under high temperature and high pressure. The hose is widely used in petroleum, chemical industry, energy, construction, steel, machinery, food, medicine and other fields, and is the well-deserved "King of Almighty".
Concrete delivery hoses are used for concrete transportation in construction machinery, such as concrete transportation hoses, pump trucks, mortar sprayers and other construction machinery, and their super wear resistance makes their service life several times longer than that of ordinary concrete transportation pipes . This product protects against acidic substances in concrete. The pipe body is made of UPE and SBR&NR synthetic rubber. The UPE material of ordinary pipes is made of domestic average molecular weight, and the UPE material used in this pipe body is imported from Germany. The molecular density is about 5 million higher than that of domestic UPE materials, so it has Great chemical stability and super high wear resistance.
