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.
