- As we delve into the realm of factories specializing in lithopone production, we encounter a plethora of challenges and innovations. These facilities are designed to operate efficiently, minimizing waste while maximizing output. State-of-the-art technologies facilitate precise control over the pigment's consistency and purity, attributes that are paramount in maintaining the high standards expected by consumers.

lithopone supplier is a white pigment (PW5) co-precipitated from solutions of zinc and barium salts according to the following reaction:


Durabo White, 24.5 per cent zinc sulphide, 51 per cent barium sulphate, 18 per cent white clay, 5.5 per cent infusorial earth.



“Unlike some other chemicals used in food, titanium dioxide has no nutritive, preservative, or food safety function—its use is purely cosmetic,” said CSPI principal scientist for additives and supplements, Thomas Galligan. “The prospect of titanium dioxide nanoparticles damaging DNA is concerning enough for us to recommend consumers avoid foods that have it.”
Polyvinyl butyral (PVB) is dissolved into 12 ~ 14% solution with ethanol and made into film. It is used for printing paper film of ceramic (or enamel) products. The fired ceramic (or enamel) patterns have bright color and smooth texture. The flower paper is characterized by convenient use, low cost, smaller than the original glue, greatly reducing the decal process and high color burning rate. At present, most porcelain factories in China have formed relatively formal production lines for standardized production. Therefore, the demand for PVB in the ceramic (or enamel) flower paper industry is increasing.
Application field of polyvinyl butyral -- electronic adhesive
Polyvinyl butyral contains hydroxyl, vinyl acetate and butyraldehyde, which has high bonding properties. Phenolic Resin was added into PVB ethanol solution to make adhesive, which can be used for a long time at 120 ℃. The product has strong adhesion to metal, wood, leather, glass, fiber and ceramics; FRP can be manufactured to replace non-ferrous metals such as steel, aluminum and copper; The adhesive made by adding this product and curing agent into epoxy resin is often used for bonding and assembly of electronic instrument components, bonding between metal and porous materials, emergency repair, etc. it can also be used in the field of electronic ceramics. In the development of ceramic integrated electronic circuits, this product with medium viscosity and low hydroxyl is used as ceramic powder adhesive to increase the primary strength of ceramics.
Application field of polyvinyl butyral -- copper foil adhesive
Polyvinyl butyral (PVB) and phenolic resin cooperate to produce copper foil adhesive, which is used in the production of copper clad laminate. It has good peel strength and tin welding temperature resistance, and is widely used in various fields.
Application field of polyvinyl butyral - self adhesive enamelled wire paint
Polyvinyl butyral is the main raw material of self-adhesive enamelled wire paint. After the enameled wire is wound and formed in the electrodes of motors, electrical appliances and instruments, as long as it is heated for several minutes at a certain temperature or treated with appropriate solvent, the coils can be bonded together by themselves without impregnation and drying.
FDA’s response
Studies of titanium dioxide as a food additive suggest health dangers
Above 10%, 1 kg of TiO2 should be replaced by 1.3 kg of lithopone supplier 30%, reducing the amount of polymer accordingly.
Titanium Dioxide/TiO2/Titanium Oxide Free Sample
On the other hand, Westerhoff said, there are hundreds of studies showing no adverse effects from the substance.
