Garlock: ABRA-SHIELD Expansion Joint Liner Material

Garlock ABRA SHIELDGarlock 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 be an option for use with a number of expansion joint products that Garlock offers – including styles 204, 206, 7250, 8400 and 9394. These uniquely constructed 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. For temperatures outside of this range, other materials in Garlock's family of abrasion resistant expansion joints would be suggested.

ABRA-SHIELD is available as a liner material option on Garlock's expansion joint products, available immediately.
