Airblock Closures


Issue: Copper cables installed along the telecommunications network are subject to constant environmental loading, which ultimately results in network faults and disruption to customer service. To address this issue – Dexgreen has developed a cable airblocking solution (Dexblock), which can be used in all cable types (i.e. grease-filled, air-core, etc)

Solution: Dexblock can be installed with low skill levels through a nozzle dispenser. To facilitate ease of installation – it is a low viscosity polyurethane compound, which allows it to quickly spread and form a seal around the substrate it needs to form a seal over (i.e. copper cables in the telecommunications network). Its primary purpose is to form a block from environmental conditions such as air, moisture and all environmental contaminants which cause faults if the cable is exposed to them for prolonged time periods.
