Product application
1. Polyvinyl chloride (PVC):
- Whitening: Rigid and soft PVC can be significantly whitened by adding 0.01% to 0.05% (i.e. 10-50 g per 100 kg of material).
- Anti-reflection: To increase transparency, use 0.0001% to 0.001% (i.e. 0.1 to 1 gram per 100 kg of material).
2. Polystyrene (PS):
- Whitening: A dosage of 0.001% (i.e. 1 gram per 100 kg of material) can effectively whiten.
- Anti-reflection: Use levels of 0.0001% to 0.001% (i.e. 0.1g to 1g per 100kg of material) can improve transparency.
3. Acrylonitrile-butadiene-styrene (ABS):
- Whitening: Add 0.01% to 0.05% to eliminate yellowing and make the appearance brighter.
4. Polyolefin:
- Polyethylene (PE) and polypropylene (PP):
- Anti-reflection: The usage amount is 0.0005% to 0.001% (that is, 0.5 g to 1 g per 100 kg of material).
- Whitening: The whitening effect can be improved by using a dosage of 0.005% to 0.05% (i.e. 5g to 50g per 100kg of material).
