CaCO3 powder 

It is white or light yellow hexagonal crystal powder, odorless, insoluble in water and ethanol, soluble in acid, and releases carbon dioxide. We specialize in super fine calcium carbonate which which is mainly used in high-grade plastic products.

Advantage: 

It can improve the rheology of plastic masterbatches and improve their formability.

Used to strengthen and strengthen the plastic, improve the flexural strength and flexural elasticity modulus, heat deflection temperature and dimensional stability of the plastic, and also give the plastic heat retardation.

Used in ink products to show excellent dispersion, transparency, excellent gloss, excellent ink absorption and high drying.

Used as an ink filler in resin ink, which has good stability and high gloss, and does not affect the drying performance of printing ink. Adaptability and other advantages.

Application:

rubber, plastics, paper making, chemical building materials, inks, coatings, sealants and adhesives and other industries.

• Precision-engineered particles
• Consistent quality standards
• Versatile applications

Flame retardant

Flame retardant, a functional additive that gives flammable polymers flame retardancy, is mainly designed for flame retardant polymers. Flame retardants are invisible patrons that can prolong the escape time in a fire

Aluminium Hydroxide：Aluminum hydroxide is the largest and most widely used inorganic flame retardant additive. As a flame retardant, aluminum hydroxide can not only be flame retardant, but also prevent fumes, do not produce droplets, and do not produce toxic gases, so it has been widely used and its use is increasing year by year.

Application:  thermosetting plastics, thermoplastics, synthetic rubber, coatings and building materials industries. At the same time, aluminum hydroxide is also the basic raw material of aluminum fluoride necessary for the electrolytic aluminum industry, and aluminum hydroxide is also widely used in this industry.

DBDPE: Organic flame retardant has a good affinity, and in plastics, brominated flame retardants occupy an absolute advantage in organic flame retardant systems. Less dosage and best Fr performance. Widely used in UL94-V0 required products.

Antimony trioxide: Inorganic halogen free additive flame retardant.  White powder at super thin particle size, and good performance. It can perform great when collaborate with other suitable flame retardant.

Zinc borate:  an environmentally friendly non-halogenated flame retardant, which is non-toxic, low water solubility, high thermal stability, small particle size, small specific gravity, good dispersion, etc., and is widely used as a high-efficiency flame retardant in plastics, rubber, coatings and other fields as a partial or completely environmentally friendly alternative to halogen-containing flame retardants,

Application:

widely used directly in the processing of plastics and rubber, such as PVC, PE, PP, reinforced polyamide, polychloride, polystyrene, epoxy resin, polyvinyl polyester resin and natural rubber, styrene butadiene rubber, neoprene, etc.

It can be used in the production of paper, fabrics, decorative panels, floor leather, wallpaper, carpets, ceramic glazes, fungicides, and coatings to improve flame retardant properties.

 It can also be used for anti-corrosion, far-infrared absorption, insect-proof and antibacterial treatment of wood, etc.
