RTP broadens halogen-free FR product range
RTP Company, a custom engineered thermoplastic compounder, has expanded its broad line of halogen-free flame retardant (FR) compounds to include nylon and polyester grades.
These new compounds provide plastics processors and OEMs with more options to meet popular green-initiative requirements driving today’s material selection processes.
Halogen-free FR products, which are fully compliant with RoHS Directive regulations, are for the first time available in nearly all resin systems – providing a viable alternative to using traditional halogenated FR additives for applications in electrical & electronics, building and transportation interior markets.
“Development of halogen-free FR materials by RTP Company has been driven by the global push for manufacturers to eliminate halogens from their products,” said Paul Killian, Technical Marketing Manager – FR Products at RTP Company.
“Our next generation halogen-free FR compounds do exactly that – while still providing the same physical property and UL94 V-0 FR performance as conventional halogenated grades.”
Recent additions to RTP Company halogen-free product line include nylons (PA 6/6, PA 6, HTN, & PPA) and polyesters (PBT, PET, & PTT) in addition to six previous resin systems.
“Increased availability of halogen-free FR plastics is a big benefit to engineers who now have a choice that doesn’t require them to compromise mechanical or FR performance when selecting a plastic material,” said Killian.
Halogen-free FR compounds from RTP Company have UL94 V-0 flammability ratings of either 1/32 or 1/16″ (0.8 or 1.5 mm). Other advantages of using halogen-free FR additives include lower smoke generation, making them ideal for enclosed space applications. They also have a significantly lower specific gravity – up to 20% less than halogenated FR grades – reducing the quantity of material used and thereby end part cost.
