Abrasion Resistance

Natural Rubber is an abrasion resistant material used in areas where other material would wear out.

Heavy Equipment Industry

• Shock mounts
• Vibration isolators
• Gaskets
• Seals
• Rolls
• Hose and tubing

Broad Chemical Compatibility

Natural rubber has been used as a versatile material in engineering for many years. It combines high tensile and tear strength with an outstanding resistance to fatigue.

To achieve the properties required for a given products, raw natural rubber can be compounded.

• Adjustable hardness from very soft to very hard
• Appearance and color ranges from translucent (soft) to black (hard)
• Can be compounded to meet nearly any mechanical requirement
• Ability to be electrically insulating or fully conductive
• Protection, insulation and sealing properties
• Absorb vibration and silence noise
• Available in any surface roughness and shape

Properties Affected by Compounds
