Genflam® XLMC‐H1 moisture cure compound is a 2 part system, the addition of 5 parts catalyst to 95 parts graft/FR will result in a jacket with excellent thermo‐oxidative stability, good fluid resistance and excellent physical properties. The material processes easily on standard extruders used in the production of wire and cable products; it will perform best on a mixing screw, with a low shear distributive mixing section.

PROCESSING TECHNIQUES

Genflam® XLMC‐H1 moisture cure compound is a 2 part system, the addition of 5 parts catalyst to 95 parts graft/FR will result in a jacket with excellent thermo‐oxidative stability, good fluid resistance and excellent physical properties. The material will process easily on standard extruders used in the production of wire and cable products. It will perform best on a mixing screw, with a low shear distributive mixing section. Melt temperatures higher than 375ºF (190ºC) should be avoided.

It is supplied as free flowing pellets, packaged in sealed foil lined boxes and has a shelf life of 1 year when stored between 50‐85ºF (10‐30ºC) in its unopened, original packaging. Pre‐drying for 4 hours at 140ºF (60ºC) immediately prior to extrusion is recommended. The foil lined bags must be properly resealed between uses, as even short periods of storage in humid conditions may cause scorch during extrusion.

CROSSLINKING CONDITIONS

Genflam® XLMC‐H1 can be crosslinked by exposed to low pressure steam at temperatures up to 175ºF (80ºC). The time period may vary due to thickness of insulation, reel size and temperature.
