Abstract:
A halogenated phenyl ether flame retardant is described having the general formula (I): wherein each X is independently C1 or Br, n is an integer of from 0 to 12, and each p is independently an integer of 1 to 4, provided that, when each X is C1, the total amount halogen in the ether is from about 50 to about 65 wt% and when each X is Br, the total amount halogen in the ether is from at least 70 wt % to about 79 wt% and wherein from about 30% to about 80%, for example from about 35% to about 75% of the halogenated ethers are fully halogenated the remainder being partially halogenated. In many embodiments, mixtures of compounds of formula I with different values of n are present. The present flame retardant provides superior mechanical properties when incorporated into a polymer than similar flame retardants which contain a higher amount of fully halogenated species.

Abstract:
A positive temperature coefficient (PTC) composition that has improved thermal conductivity and that includes a thermoplastic polymer, carbon black and graphite. The compositions offer improved thermal conductivity and/or rheology of the PTC composition as compared to compositions that do not include graphite, or that use smaller graphite particles. The compositions may also include one or more additives. The PTC compositions of the present invention offer improved thermal conductivity at most any temperature and permit PTC materials to be designed that can be tailored to operate at different temperatures based upon the thermoplastic polymer used.
