Lide powder not only has a great role in the coatings industry, but also has a wide use space in the plastics industry. Let's take a look at what role Lide powder plays in the plastics industry.
Lithopone is one of the most commonly used white pigments. Its position is second only to titanium dioxide. As a multifunctional white pigment, its blue phase has a white phase and has a toning effect. It can be used in combination with fluorescent whitening agents. The qualities and advantages that plastic products cannot impart to other white pigments.
First, glass fiber reinforced plastic
Because Lide powder has a Mohs hardness of only 3, studies have proven that it is very suitable as a white pigment for glass reinforced plastics. The advantage is that it does not destroy the reinforcing glass fiber like TiO2 in the process of forming, so that the bending strength or impact strength of the finished product does not have a negative impact.
Second, the flexibility is good
Since lithopone is very soft and has no photocatalytic activity of TiO2, it is well suited for coloring and opacifying natural and synthetic elastomers. Therefore, the wearability is small, and the sole produced using the white elastomer of Lide powder as the pigment has a much longer service life than the TiO2.
Third, thermoplastics
As a stabilizer, lithopone is also inventively applied to some thermoplastics, especially PP and PBT, to improve the thermal stability of the polymer. There is no conclusive explanation for the mechanism among them. However, we believe that it is because Lide powder can react with most catalytic metal ions to form an immobile complex, which avoids the catalytic degradation caused by these ions entering the polymer lattice. The "fixed effect".

Flap discs are made by Aluminum oxide,calcined aluminum, SIC or zirconia coated cloth, also call as power flex discs. Flap discs have the advantages of grinding discs and fiber discs, making it easier for grinding and polishing disposable, reducing the work process and lower the grinding cost.
Abrasive grains include: Aluminum oxide, calcined aluminum, silicon carbide and zirconia.
Flap discs are widely used in grinding and polishing of wood, glass, stainless steel, futniture, mold, metal casting, weld seams and so on. Especially, zirconia power-flex discs fit in sanding seld seam of stainless steel. Flap discs have the features of quick speed, high efficiency, synchronous consumption, strong grinding force, fast heat disspation and good performance.
