Why do you need fluorescent whitening agent for extruded board?

Because of its special structure and high compressive strength, extruded board is widely used in decoration, decoration, thermal insulation and other fields. Extruded boards are generally used inside walls, although they are not exposed outdoors, but many manufacturers will produce a lot of extruded boards for stock-up. We all know that if too many goods are stocked, they can't be sold completely at one time, and after a long time, they will be yellowed, dull and old in color, which will also affect our sales. So how to avoid this problem? We suggest adding an additive-extruded board fluorescent whitening agent in the production process to solve it.

Which type of whitening agent is effective for extruded board?

As extruded boards are commonly used in industry, many manufacturers also produce lots of stocks for standby. Extruded boards are favored by many consumers because of their excellent characteristics such as no aging, no decomposition and no harmful substances after long-term use. However, there are many types of fluorescent whitening agents. Which one is special for extruded board? We suggest using fluorescent whitening agent OB for extruded board.

The appearance of fluorescent whitening agent OB is pale yellow powder, which is a general whitening agent in the field of plastics. The reason is that it has good light transmittance and weather resistance, and is suitable for all kinds of plastics. If the temperature is not particularly high in the production process, whitening agent OB can be selected, and its melting point is 196-203℃.  To produce extruded board, add 300-500g to a ton of old materials, or about 100g to a ton of new materials, so that the brightness and whiteness of the product can be obviously improved.

We suggest that the manufacturer must be selected when choosing the fluorescent whitening agent for extruded board. The market of fluorescent whitening agent is rather chaotic, and many suppliers dilute the whitening agent to reduce its purity and sell it at a low price, resulting in unsatisfactory use effect of the whitening agent, which makes the end customers lose confidence in the whitening agent and think that it has no effect.
