China fluorescent whitening agent FP-127 for PVC foam board
Jinan tonex chemical, factory of all kinds of optical brightener agent, such as optical brightener FP-127, optical brightener CBS-127 , fluorescent whiteningagent FP-127 for PVC foam board has the following characteristics andadvantages:
Basic characteristics:
Appearance: Usually light yellow or milky white crystalline powder with blue-violet light color.
Chemical properties: The chemical name is 4,4-bis(2-dimethoxystyryl)biphenyl. The molecular formula is C30H26O2 and the molecular weight is 418. It is insoluble in water, odorless and has stable performance.
Technical indicators: The melting point is between 216-222°C. The purity is relatively high, generally ≥99.00%. The maximum absorption peak is 368nm and the maximum fluorescence reflection is 436nm. The specific gravity is 1.23g/m3.
Whitening effect:
Highly efficient whitening: It has a very good whitening effect on PVC foam boards and can significantly increase the whiteness and brightness value of the boards, making the foam boards look white and beautiful. It stands out among many fluorescent whitening agents.
Low dosage: Only a small amount of FP-127 is needed to achieve the ideal whitening effect. The addition amount is generally 0.01%-0.05% (by weight ratio to plastic raw materials).
Compatibility with PVC materials:
High affinity: It has a higher affinity with PVC materials and can be evenly dispersed in PVC foam boards without easy agglomeration or precipitation, ensuring the uniformity of the whitening effect.
Good stability: It solves the problems of traditional whitening agents being prone to precipitation and yellowing. It has good stability in PVC foam boards and can maintain a good whitening effect even after long-term use.
Other properties:
Better weather resistance: It has certain sun resistance and weather resistance, and can resist the influence of external factors such as ultraviolet rays to a certain extent, maintaining the color stability of the foam board and making the product not easy to fade.
Strong acid and alkali resistance: It has strong acid and alkali resistance and can adapt to different production processes and environmental conditions during the production of PVC foam boards.
When using the specialfluorescent whitening agent FP-127 for PVC foam boards, it needs to be addedand stirred evenly with the raw materials during the foaming process. In termsof packaging, it is generally packaged in 10 kilograms/25 kilograms cardboarddrums and stored in a cool, dry and ventilated place.
