The company has world-leading production equipment and strong manufacturing capabilities. Welcome to wholesale custom made hollow rubber hose from our factory.
Material Properties
High temperature resistance and wide temperature adaptability
• Using EPDM ethylene propylene rubber material, it has excellent heat resistance and cold resistance;
• It can work stably for a long time in extreme temperatures from -40℃ to +150℃, especially suitable for high temperature hydraulic systems or fluid transmission in 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 the erosion of 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 shifting, and ensures 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's tear resistance is increased by more than 50%, and combined with the mechanical distribution of the hollow structure, it can withstand high pressure conditions (0-40MPa) while avoiding the risk of rupture due to local stress concentration.
Lightweight and customizable
• The hollow tubular design reduces weight by 40%, reducing system load;
• Supports color (black, white, gray, transparent), hardness and size customization to meet the interface requirements of different devices.
Customized Services
Materials
