Instructions for use:
- Rigid PVC: When whitening, use a concentration of 0.01-0.06% (that is, use 10-60 grams per 100 kilograms of material); when using anti-reflection, use a concentration of 0.0001-0.001% (that is, use 0.1-1 grams per 100 kilograms of material).
- Polystyrene (PS): When used for whitening, the concentration is 0.01-0.05% (i.e. 10-50 grams per 100 kg of material); when used for anti-reflection, the concentration is 0.0001-0.001% (i.e. 0.1-1 gram per 100 kg of material).
- Polyvinyl chloride (PVC): When whitening, use 10-50 grams per 100 kilograms of material; when anti-reflection, add 0.1-1 grams per 100 kilograms of material.
