Linagard ® OZ Technical Specifications Excellent resistance to abrasion, UV light and ozone attack 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 sunligh\ t and high ozone concentrations. Design Features • Excellent weathering and ozone, sliding abrasion and el ectrical resistance, and resistant to most inorganic chemicals • Produced with the addition of antiozonant agents • High resilience • Remark able cut and tear strength • Good sound absorption and vibration dampening properties Applications • Linings for hydrocyclones and hoses handling dry powder • Where static electricity build-up may cause increased ozone levels • Fabricated or moulded components that are frequently exposed to sunlight Siz e/Availability • Standard sheet size: 9.25 m x 1 .23 m nominal (approx. 30ft x 4ft) • Standard thickness range: 1.5 mm to 30.0 mm (approx. 1?16” to 1 3?16”) 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.
