Garlock introduces ABRA-SHIELD™

Garlock has launched ABRA-SHIELD™, a proprietary expansion joint liner material designed for abrasion resistance and sustainability in demanding high temperature operating conditions.

ABRA-SHIELD™ will join ABRA-LINE® and natural rubber to provide a variety of liners that cater to increased abrasion protection. ABRA-SHIELD™ will be an option for use with a number of expansion joint products that Garlock offers,including styles 204, 206, 7250, 8400 and 9394. These joints also provide high levels of protection from stress, misalignment, vibration, noise, shock and corrosion.

Media type and temperature play a significant role in the selection process of an expansion joint liner material. The specialty formulated hydrogenated nitrile butadiene rubber used in ABRA-SHIELD™ performs significantly better than common abrasion resistant solutions, with an operating temperature range up to 300°F.

In abrasion resistance testing – which provides data to compare materials and predict the lifetime of a material or coating – ABRA-SHIELD™ provided 50% higher abrasion resistance than standard EPDM (ethylene propylene diene monomer rubber). ABRA-SHIELD™ will be the recommended solution in abrasive applications (such as slurry, ash and brine) with sustained or spiked temperatures between 180°F and 300°F.
