Low Smoke Performance Materials

Low Smoke Cables (LSF)
The Deciding Factor in Cable Performance

Chemically pure materials are often ideal for use as insulation. Low Smoke materials such as PTFE and  HFI 90 provide high insulation resistance and low dielectric loss. Some insulation materials like HFI 120 can be used for inner sheaths, but do not have the rugged properties necessary for use as an outer sheath.

Our fluoropolymers are halogenated high temperature materials that are highly flame retardant. They do not generate much smoke and are exceptional in oils and fuels. Due to their thin wall nature they are not ideal as jacketing materials, but are often used in this way on smaller sized cables.

What is available?
There are a number of different groups of materials. Each has its own distinct properties, benefits and uses.

Fluoropolymers for High Performance - ETFE, FEP, PTFE, PFA, LSI 155

Fluoropolymers are halogenated high temperature materials that are highly flame retardant. They do not generate much smoke and are exceptional in oils and fuels. Due to their thin wall nature they are not ideal as jacketing materials, but are often used in this way on smaller sized cables.

Polyesters such as TPS 100 are generally higher temperature materials than polyolefins and can be used thinner due to their tougher nature.
