Hypophosphorous acid metal salts powders and non-flammable inorganic or organic aluminum salt of phosphorous are used as flame retardant agents in flame retarded compositions suitable for polymer materials.

Non-flammable hypophosphite metal salt based powders and their use as flame retardant ingredients

The present invention relates to halogen-free flame retardant compositions, comprising polyolefins polymers as active ingredient and a flame retardant system. The flame retardant system comprises at least an Hypophosphorous acid metal salt (preferred is Aluminium hypophosphite) as main flame retardant component, at least a sterically hindered N-alkoxyamine with a specific structure as first flame retardant synergic component, at least a silicon oxide or aluminium oxide or a mixture thereof with specific properties as second flame retardant synergic component.

Polyolefins halogen-free flame retardant moulding compositions comprising an inorganic hypophosphorous acid metal salt

The present invention relates to halogen-free flame retardant compositions essentially comprising polyamide polymers (preferred is polyamide 6), at least a hypophosporous acid metallic salt (preferred is aluminum hypophosphite), at least a nitrogen based flame retardant agent (preferably selected among melamine condensation products such as melam, melem, melon or their mixtures, and melamine cyanurate), at least an organic polyhydric compound and optionally further conventional components. Such compositions are highly flame retardant.

Halogen-free flame retardant polyamides composition

Object of the present invention is to provide halogen-free highly flame retardant styrene impact modified polymers able to perform V0 classification on thin items, according to international standard UL-94.

Environmental friendly flame retardant moulding compositions based on thermoplastic impact modified styrenic polymers

The present invention relates to halogen-free flame retardant compositions essentially comprising polyamide polymers (preferred is PA6), at least an Hypophosphorous acid metal salt (preferred is Aluminum hypophosphite), at least an organic phosphinate metal salt (preferred is Aluminum Di Ethyl Phosphinate), at least a Nitrogen based flame retardant agent (preferred is Melamine Cyanurate), at least an organic polyhydric polymer (preferred is EVOH) and optionally further conventional components. Such compositions are highly flame retarded at low thickness and have high Glow Wire temperature resistance.

Halogen-free flame retardant polyamide moulding compositions with increased glow wire and fire resistance

The invention disclose halogen free thermoplastic or cross linked polymers compositions comprising a polyolefin and/or a polyolefin containing polar co-monomers and a combination of metal hydroxides and inorganic hypophosphite as a synergic, and optionally other ingredients. These compositions show a superior balance of flame retardant properties compared to already known corresponding halogen free formulations. Molded items obtained using the polymer composition according to the present invention are useful in a wide range of injection molding and extrusion applications, especially cables.

Flame retardant polymeric composition

The invention relates to flame retarded extruded polystyrene foams with a very low halogen content in the final product, i.e. containing a very low content of hexabromocyclododecane or preferably hexabromocyclododecane free, and a process for their preparation. The invention also relates to their use in construction, as building thermal insulating materials, or in transportation.
