Non-bromine and non-antimony compositions for low flame and low smoke polyvinyl chloride compounds and constructions

Abstract

Materials for making bromine- and antimony-free polyvinyl chloride (PVC) compounds and constructions that have low flame and smoke properties as well as low brittleness properties. The compositions are especially useful for making cable jackets, particularly riser and plenum cables. The compositions contain PVC resins, plasticizers, non-brominated flame retardants, fillers and stabilizers, and optionally smoke suppressants.
