Getting To Know Materials: Urethane (Polyurethane)

Durability

Urethane is one of the strongest elastomers and can withstand plenty of abuse. This material has tensile strength and is abrasion-resistant. It boasts many advantages and being able to withstand ozone, weathering, chemicals, and high pressure sealing situations.

Hydraulic Fluids & Oils

Urethane has the ability to be used in many places however, it has one of the best resistances in hydraulic fluids, oils, fuels, and many different hydrocarbons. This material is a must when it comes to sealing high-pressure hydraulic systems.

Strong Acids

Despite urethane having great properties, there are certain applications urethane isn’t preferred for. Due to its chemical makeup, urethane has a low resistance to most strong chemicals such as Acetic Acid and Acrylic Acid. If you are looking to seal acids, EDPM (Ethylene Propylene) would be one of the best materials to use. 

Get To Know Materials: Ethylene Propylene

EPR is a great material to be used in many different fields, especially when it comes to commercial aircraft. It offers great ozone, water, steam, acid, and base resistance. However, it lacks in petroleum sealing. Temperature...

Get To Know Backup Rings 

Backup rings are commonly installed with O-Rings to improve their performance. Backup rings are useful for many different reasons but the main reason is by blocking or reducing the extrusion gap. This prevents the O-Ring inside to be damaged or extruded causing...
