Ningbo Zhonggao Rubber & Plastic Manufacturing Co., Ltd. is one of the most reliable manufacturers and suppliers of hollow rubber tube in China. The company has world-leading production equipment and strong manufacturing capabilities. Welcome to wholesale custom made hollow rubber tube from our factory.
Material Properties
High temperature resistance and wide temperature adaptability
• Made of EPDM terpolymer rubber, it has excellent heat resistance and cold resistance;
• Can work stably for a long time at extreme temperatures from -40℃ to +150℃;
• Especially suitable for fluid transmission in high temperature hydraulic systems or low temperature environments.
Corrosion resistance and chemical stability
• EPDM rubber has a dense molecular structure and is highly resistant to ozone, ultraviolet rays, acid and alkali solutions, and most organic solvents;
• It can resist erosion by industrial chemicals, oils, and corrosive media, extending the service life of the pipeline.
High elasticity and resistance to distortion
• The material elastic modulus is optimized to ensure that the hollow tubular structure rebounds quickly when bent or compressed;
• It effectively prevents the pipeline from twisting, collapsing or displacement, ensuring the stability of fluid transmission.
Low friction and wear resistance
• The surface is treated with special technology, and the friction coefficient is reduced by 30%-40%;
• With the high wear resistance of EPDM rubber;
• The wear rate under dynamic conditions is only 1/3 of that of ordinary rubber;
• The service life is 2-3 times longer than that of solid hose.
Tear resistance and pressure bearing capacity
• The material tear resistance is increased by more than 50%, and can withstand high pressure conditions of 0-40MPa
Lightweight and customizable
• The hollow tubular design reduces weight by 40% and reduces system load;
• It supports color (black, white, gray, transparent), hardness and size customization to meet the interface requirements of different devices.
