Melamine cyanurate in combinatimi with magnesium hydroxide (Mg(OH)2 or MH) or even with talcum (Japanese patents), melamine polyphosphate (DSM, type Melapur 200), also suitable for PA 6.6 GF, are two examples of more recent developments. Zinc sulfide can replace antimony trioxide in some cases. [Pg.112]

A small amount of Melapur 200 (melamine polyphosphate) with a metal hydrate leads to a strong reduction in the rate of heat release. The combination allows a lowering of the loading to 50% instead of 65% and still retains the same peak rate of heat release as with 65% magnesium hydroxide in EVA. The effect of Firebrake ZB has been shown to further reduce the overall level of heat release and create a hard, cellular protective structure. In vertical bum tests like UL94, however, this stmcture is not created and leads to a loss of classification. Current work is endeavouring to improve vertical burning behaviour of these formulations.

DSM (now Ciba) offers the Melapur range of melamine flame retardants. [Pg.51]

The main advantage of melamine phosphate (Melapur MP) is its low water solubility compared with ammonium-based phosphates. Applications range from thermoplastics to thermosetting resins. [Pg.51]

Melapur 200 is expected to have a good share of the market for the protection of E E goods. [Pg.52]

Melapur P46 is a synergistic formulation of nitrogen and phosphorus-containing compounds, developed for polyolefins, particularly polypropylene. [Pg.52]

Melamine cyanurate, Melapur MC, is less successful in glass filled polyamide compounds than Melapur 200, but works well in uiu-einforced PA66 or a mineral-filled formulation, achieving V-0 at 6-10% loading for the former, and at 13-15% in the latter. [Pg.52]

Melapur MC can be used also in epoxy and polyester resin mixes as well as in PET, st5UTenic compounds and polyolefins. [Pg.52]

Melapur MC can provide cost-effectiveness, good electrical and mechanical properties, as well as offering advantages in health and safety and colour performance. [Pg.52]

Melapur MC is regarded as a workhorse for standard polyamide compounds, since it cannot achieve V-0 due to lack of heat resistance in reinforced PA66 formulations. One of the other problems facing all users of MC is the intrinsically low bulk density that follows the requirement for a low particle size distribution. The solution is a free-flowing version designated as Melapur MC XL. [Pg.53]

Melamine FRs are a small but growing market. In 1996, DSM merged the melamine FR activities of DSM Melamine and the fine chemicals operation of DSM Chemie Linz to form DSM s Melapur BV, which became the largest producer of such additives in Europe. [Pg.88]

Ciba Specialty Chemicals increased its flame retardants portfolio in May 2002 by purchasing DSM Melapur Flame Retardants, a leader in melamine-based technology, mainly utilised in engineering plastics for the automotive and electrical electronic sectors. This complements their Flamstab technology, used for polyolefins. Ciba will retain the Melapur trademark and the two companies are expected to work together to find new flame-retardant methods based on melamine chemistry. [Pg.88]

A more recent member of this family is melamine polyphosphate (MELAPUR 200, originally from DSM, now from Ciba), which has a thermal stability advantage for use in polyamide 6 and 66 (61) and in combination with char-assisting additives, in polyolefins such as those used for stadium seating.
