Technical Specifications

Minerals - Bonding Systems and Installation

Specifically designed two-part bonding systems are available from Weir Minerals. Please consult your local representative for advice on the most suitable bonding method.

Design Features

• Excellent resistance to abrasion, UV light, and ozone attack
• Excellent weathering and ozone resistance, and resistant to most inorganic chemicals
• Produced with the addition of antiozonant agents
• High resilience
• Remarkable cut and tear strength
• Good sound absorption and vibration dampening properties

Linagard® OZ rubber is a natural rubber vulcanisate formulated for excellent resistance to abrasion, UV light, and ozone attack. Linatex® premium rubber is well known for its properties of resilience, abrasion resistance, and vibration and noise absorption. In certain applications, however, where high levels of ozone or UV light are present, unprotected pure natural rubber may be subject to surface deterioration. Linagard® OZ overcomes this potential limitation. Linagard® OZ rubber offers excellent resistance to sliding or slurry abrasion in combination with resistance to prolonged exposure to sunlight and high ozone concentrations.
