Discussion on transparent inorganic fillers
Since ancient times, people have a lot of love for transparent things, but due to the limitations of industrial processes, the production of transparent products in ancient times is a big problem, with the development of society, people for transparent, transparent things to pursue a higher level, such as transparent car paint, wood paint, transparent plastic products, lampshade board; But the more transparent products, the more stringent the demand for materials, the higher the cost, so reducing the impact of inorganic fillers on transparency in transparent products to reduce production costs is something that many manufacturers like to see.
The same as many resin raw materials, inorganic fillers are divided into transparency from the raw ore, and can also be divided into transparent, translucent and opaque three, and the transparency difference in addition to the naked eye observation, the most important is based on the transmittance (the ratio of the total amount of incident light to the total amount of light through the medium) as a reference.

The color of transparent inorganic filler ores is generally colorless and transparent, and some ores may show other colors, but the overall transparency is not as good as colorless ores, and after grinding into fine powder, the powder is white;
Compared with ordinary fillers, transparent inorganic fillers have better transparency in the product, and have better improvement in the overall surface beauty;
The permeability of different inorganic fillers in modified PP is different
In addition, in addition to the different mineral categories will affect its transparency in the product, the fineness of the mineral powder on the transparency of the impact is more obvious, generally speaking, the larger the mesh of the mineral powder, the finer the particle size, the greater the overall apparent structure damage, the lower the transparency, but the overall mechanical properties will be relatively good, so choose the appropriate mesh, It's the key to making a good product.

With the continuous improvement of the society for mining, impurity removal and production process, transparent inorganic fillers are now slowly entering the filler market, playing a significant role in coatings, modified plastics and other industries, such as your company's products in the transparency of certain needs, you can consult our company, we will be happy to serve you.
