  • Halogen-free, flame retardant composition for wire and cable applications
    Patent number: 9336927
    Abstract: A halogen-free, flame retardant composition comprises: A. A polymer blend comprising: 1. Polypropylene, and 2. Thermoplastic elastomer (TPE) other than the polypropylene of (A)(1), and B. An intumescent flame retardant comprising at least one of: 1. A compound of Formula 1 where M is at least one of melamine, morpholine, piperazine, piperidine, alkyl hydroxyl and a triazine polymer of Formula 2 where D is a heterocyclic or polyamine moiety, and m and n are independently integers the sum (m+n) of which is less than 1000, and 2. A piperazine phosphate.

  • Thermoplastic polymer and novolac composition and method
    Patent number: 8283406
    Abstract: Compositions comprising a novolac polymer, an olefin-based polymer with an epoxy group, a filler and optionally a thermoplastic polymer are provided. The compositions may be halogen-free. The present compositions exhibit excellent compatibility between the novolac polymer and the olefin-based polymer with an epoxy group resulting in compositions with superior mechanical properties.
