DESCRIPTION
Dibasic Lead Phosphite (Diphos) is produced and supplied as a fine white powder. With a lead (Pb) content of 83.5% it confers excellent long term weather protection on both rigid and flexible PVC compounds. It has a high refractive index which imparts a higher opacity than other basic lead compounds. The product is packed in either 25kg multi-ply paper sacks or in 1000kg bulk bags.
TYPICAL APPLICATIONS
Diphos is particularly effective in inhibiting the degradation of PVC exposed to UV radiation, thus it may be used as the primary stabiliser in products intended for outdoor applications. It is effective in both rigid and flexible formulations for mouldings, extrusions and calendered products such as cable sheathing, rainwater fittings and window frame profiles. Diphos is very effective when used in conjunction with Tribasic Lead Sulphate.
