The finished thermoplastic polymer products containing the notified chemical will be distributed to numerous premises around Australia. Antioxidant stabiliser for thermoplastic polymers. It may be used in automotive applications such as bumper bars, interior trim, marine fittings and industrial applications such as building panels, roofing, construction, housing and crates. Masterbatch production The notified chemical (> 95% concentration) will be emptied into a feed hopper of the blending vessel local exhaust ventilation and blended with other ingredients in a closed vessel to concentration levels of up to 15% in the resulting powder blend. It will then likely be further processed into masterbatches, involving weighing of the powder containing the notified chemical and loading into mixers under local exhaust ventilation. The resulting masterbatch is expected to contain the notified chemical at concentrations of less than 0.1%. Moulding of plastic articles The masterbatches will then be transported to customer sites where they may be mixed with other ingredients (notified chemical present at less than 0.1%) and subsequently moulded into the shapes of the required plastic articles.
