| Application | It is mainly used in the whitening of plastic and synthetic fibre products, and also has an obvious brightening effect on coloured plastic products. It is also used in large quantities in ethylene/vinyl acetate (EVA) copolymers and is a suitable fluorescent whitening agent for sports shoes. It is also widely used in PE, PP, PVC, PS, ABS, PMMA and other plastic films, molding materials, injection molding materials and polyester fibers. It also has a good effect on the whitening of paints and natural lacquers. |
Whitening masterbatches, foaming masterbatches, filling masterbatches, functional masterbatches, flame retardant masterbatches and other colour masterbatches.
1. For plastics or resins, the general dosage is 0.01-0.03%, i.e. about 10-30 grams of fluorescent whitening agent per 100 kg of plastic material. (Users can adjust the specific amount of whitening agent according to the whiteness requirements. If UV absorbers such as titanium dioxide are added to the plastic raw materials, the amount of whitening agent should be adjusted appropriately. )
2. PE material whitening agent reference dosage: 10-25g/100kg.
3. Plastic material PP material whitening agent reference dosage: 10-25g/100kg plastic material.
4. PS material whitening agent reference dosage: 10-20g/100kg plastic material.
5. PVC material whitening agent reference dosage: 10-30g/100kg plastic material.
6. ABS material whitening agent reference dosage: 10-30g/100kg plastic material.
7. EVA material whitening agent reference dosage: 10-30g/100kg of resin.
8. If used in transparent plastic film, the reference amount of whitening agent: 1-10 g/100 kg of plastic material.
