Uvtec

Compounders in the US, such as UVTEC Inc., have brought out metal hydrate concentrates under the name Safe FR. These concentrates are loaded with in excess of 70% magnesium hydroxide and find uses in polyolefin systems for wire and cable, building products market and in the E E sector. 

These may present some problems in incorporation into compounds while maintaining the desired physical properties, but a zero-halogen magnesium hydroxide flame-retardant concentrate on a polyolefin base (by Uvtec under the name Safe FR 5000) can easily be dispersed into polyolefin products. It is predispersed to run on existing PVC production equipment and is non-corrosive and non-abrasive to processing equipment. It is halogen free, with low smoke and no acid combustion gas. There is no leaching of the flame-retardant component and it is recyclable and environmentally safe, available in UV-stabilized formulations.
