Chase & Sons A162A

Material supplier:

Chase Corporation

Industry:

Wire and cable

Application:

Moisture block primary cable coating.

Dispensing a hot-applied, butyl-based, inert compound such as Chase BlH2Ock® into a heated coating head where bare cable strands are pulled through during the stranding process. The coating fills the interstices between the wire strands, thus preventing ingress & migration of moisture into the cable. The coating can also facilitate adhesion of moisture swellable powder applied downstream, which further inhibits moisture penetration. The dispense temperature ranges from 300°F to 375°F (149°C to 191°C).

Material specs:

• Chase & Sons® A162A
• Chase BlH2Ock® strand fill

Chase & Sons® A162A is a unique, flexible, semi-conducting thermoplastic compound designed as a strand-filling, water-blocking agent for stranded conductor power cables. Pumped into the interstices of the stranded conductor core during the stranding operation, Chase BlH2Ock® is designed to prevent ingress and longitudinal migration of water within the conductor.

The highest throughput capacity in the industry

Graco Therm-O-Flow® bulk hot melt adhesive systems consistently outperform the competition and provide the best performing industrial bulk hot melt supply systems on the market. Therm-O-Flow provides a throughput capability more than 200% higher than the leading competitor when using PSA and butyl hot melt adhesives.

Therm-O-Flow’s advanced temperature control capability and melt-on-demand process virtually eliminates overheated material, resulting in a better adhesive quality and reduced rework due to degraded material. Learn more about the Therm-O-Flow 200.
