- Capacity to endure a broader spectrum of temperatures and chemicals
- Commendable tensile strength and flexibility
These qualities make reinforced EPDM material a dependable option ideal for industrial use. They are typically constructed using extrusion, a method that involves forcing the EPDM rubber compound through a die with the desired cross-section to create the hose.
EPDM material are commonly reinforced with materials such as polyester or aramid fibers, which contribute to the hoses’ strength and durability. The reinforcement process enhances the hose’s flexibility by mitigating the risk of collapsing under vacuum or bursting under high pressure. Reinforced EPDM hoses are most suitable for applications that necessitate resistance to elevated temperatures, chemicals, and weathering. They are frequently utilized in industries such as automotive, HVAC, agriculture, and construction.
Specialty EPDM Hoses
For specific industry needs and requirements, specialty EPDM material are the way to go. These hoses are meticulously engineered to withstand:
