Why Rubber Is Used As Vibration Absorbers

Why Is Rubber Used As Vibration Absorbers? Rubber is used as vibration absorbers, because rubber has a relatively high shear modulus compared to other materials. That means when a rubber material is shear stressed, i.e. stressed parallel to its cross-section, rubber can be stressed more before it becomes permanently deformed. In other words, when stress […]

Which Rubber is Fire Resistant

What Are the Fire Resistant Rubber? Neoprene, Viton, and silicone are all fire resistant rubber. Neoprene’s Fire Resistance Although Neoprene was designed for its various oil and chemical resistant properties, Neoprene can also withstand burning and high temperatures. Neoprene is rated for operating temperatures up to 200°F. When heated past 200°F, Neoprene may stiffen. Neoprene […]
