Optical Brightener FP-127 is mainly to white PVC products,such as pvc foam board,pvc sheets,pvc pipe,pvc profile,PVC cast film etc. Optical Brightener FP-127 whitness is better than Optical Brightener OB,but weather resistance Optical Brightener OB is better than Optical Brightener FP-127.


Optical brightener FP-127 Usage: This product has good whitening effect on all kinds of plastics and plastic products, especially for PVC, PP and other plastic products, especially for artificial leather products, and has the advantages of long-term storage without yellowing and fading.

Optical brightener FP-127 cas no.40470-68-6 for PVC foam plastics

According to the performance characteristics of PVC foamed plastics, it is recommended to use fluorescent whitening agent fp-127 for PVC foamed board. This Optical brightener FP-127 is light yellow powder in appearance, which solves the shortcomings of Optical brightener fp 127, such as weather resistance, fading and yellowing after long-term use. It has higher whiteness and brightness value, better stability, less dosage, only 0.01% - 0.05% addition, and good thermal stability, It almost meets the processing temperature of most PVC foamed plastics, and is highly praised by most PVC foamed plastics manufacturers.

Optical brightener FP-127 cas no.40470-68-6 for PVC pipes

PVC pipes can be divided into rigid pipes and flexible pipes. For rigid PVC pipes, we suggest that you apply optical brightener fp-127, which can be used in a variety of PVC plastic products. With a very small amount of 200-300g per ton, the whiteness and brightness of the products will be greatly improved. For PVC hose, there are many hose is completely transparent, which requires that people's fluorescent brightener's light transmittance should be better. Here, we propose to use optical brightness ob, which has good reliability, light transmittance and aging resistance. At present, it is highly praised by many PVC hose manufacturers.

Optical brightener FP-127 cas no.40470-68-6 for PVC profiles

You use fluorescent whitening agent not only to increase the color of PVC profile white and bright, but also to keep the later in the process of use does not fade, not yellowing. To solve this problem, we suggest to use optical brightener fp-127.

Optical brightener fp-127 is suitable for all kinds of PVC plastic products, especially for special effects in profiles. 0.02% - 0.03% will be added in one ton, and the white value of the product will be improved a lot. The most important thing is that there will be no yellowing and fading in the later period. As far as the cost is concerned, it will not increase much. At present, it is also highly praised by many PVC plastic manufacturers.

Optical brightener FP-127 cas no.40470-68-6 for insulation board

Most of our common insulation board is made of EPS material, which has excellent fire performance. It belongs to A-pole non combustible material, which can meet the requirements of external wall insulation and fire insulation with high fire resistance; The thermal insulation effect is good, the thermal conductivity of magnesite foam exterior insulation board is low, and the thermal insulation effect is outstanding; Light texture, saving transportation cost; It has good frost resistance and can keep its physical and chemical properties stable in complex weather changes; Good aging resistance, with the same life as the building; Sound insulation performance is good, magnesite foam insulation board contains a large number of independent bubbles, sound absorption capacity is 5-7 times of ordinary concrete. It is because the insulation board has so many excellent properties that more and more manufacturers produce insulation board. If there are more manufacturers, the competition will be fierce. We see the insulation board is usually white, many manufacturers in order to make the product whiteness and brightness, improve sales, will add insulation board fluorescent whitening agent, but fluorescent whitening agent model so many, which is suitable for insulation board use?

According to the performance of the insulation board, we recommend that you use Optical brightener fp-127. The addition amount of optical brightener fp-127 is very small, only 0.02% - 0.05% is added in one ton. The whiteness and brightness of the product have been greatly improved, and there will be no yellowing in the later stage.
