Natural rubber is extremely durable, stretchy, wear-resistant and has very good tensile strength. Natural, or NR rubber, is ideal for use in anti-vibration products and in places where wear resistance is important. Natural rubber is waterproof, resistant to most salts, weak acids and many other chemicals. Not suitable for use in environments containing ozone, strong acids, animal fats, oils and lubricants, does not tolerate many hydrocarbons. Natural rubber is non-greasy and non-toxic. Used, for example, as a vibration damper under machine feet. Color: red, beige
