How to Achieve a UL 94 V-0 Rating with Brominated Flame Retardants
BT-93W (Ethylene Bis-Tetrabromophthalimide): Applications and Specifications
Requirements for cable
Cable insulation and jacketing must pass vertical flame tests while keeping electrical insulation, flexibility and long-term heat ageing. Brominated flame retardants with antimony trioxide are widely used in polyolefin and crosslinked PE cable.
Product choices
DBDPE is a strong choice for PP and PE cable compounds thanks to its thermal stability and low volatility. For higher-temperature or thinner wall constructions, finer grades and optimised ATO levels keep the compound processable.
Balancing properties
Over-loading flame retardant degrades elongation and dielectric strength. The goal is the minimum loading that passes the required flame test, using the synergist to reduce total additive.
Frequently Asked Questions
Which flame retardant is used in wire and cable?
Brominated flame retardants such as DBDPE, combined with antimony trioxide, are common in polyolefin wire and cable compounds.
Does flame retardant affect cable electrical properties?
Yes. Excess loading can lower elongation and dielectric strength, so the minimum effective loading with a synergist is preferred.
