A new flame-retardant for polypropylene, Reogard 1000, actually increases the heat distortion temperature of the formulated polymer. Reogard 1000 is a phosphorus-nitrogen based, intumescent flame retardant from Great Lakes Chemical.
It has unique properties allowing it to be melt blendable at polypropylene processing temperatures. It is more efficient than other commonly used flame retardants, which helps to reduce the specific gravity of the polymer. Reogard 1000 is also non-blooming, offers good electrical properties and has a reduced tendency to absorb water.
Reogard is recommended for use in V-0 polypropylene homopolymers and low polyethylene content co-polymers.

High-flow HDPE cuts molding time
A high-flow high-density polyethylene (HDPE) for thin-wall molding is available from Equistar. Alathon H 5656 is higher in stiffness and has a higher recrystallization temperature than most conventional high-flow HDPE resins. As a result, part set-up faster after molding and cycle times are reduced.
