Product Description

Tourmaline powder is derived from mechanically pulverizing raw tourmaline ore after removing impurities. The processed and purified tourmaline powder has high far infrared emissivity. The general chemical formula of tourmaline is NaR3Al6Si6O18BO33(OH,F)4, and the crystal tourmaline belongs to the general term of a family of cyclic silicate minerals in the trigonal system. Usually the body of tourmaline crystal is triangular column with different crystal shapes at both ends. The columns have vertical stripes, often in columnar, needle-like, radial and massive aggregates. For referring to physical properties, tourmaline has the following ones: glass luster, fracture rosin luster, translucent to transparent, no cleavage, Mohs hardness 7-7.5, specific gravity 2.98-3.2 with piezoelectricity and pyro-electricity.




 

Product Application:
Functional masterbatch, PP polypropylene, Meltblown non-woven fabric, Paints&Coatings, Cosmetics, etc.

The most common usage of tourmaline powder is using as electret in the processing of the melt-blown nonwoven fabric. During the process, tourmaline powder and the carrier particles turn into electret under high voltage of 5-10kv by a static electricity generating device to improve the filtration efficiency and brings benefit of anti-bacteria. Electret refers to an electrolyte material that has the function of storing charges for a long period.
Tourmaline could be used as masterbatch by mixing with other materials such as pp capsules during the manufacturing of melt-blown fabric.

Tourmaline Powder is used in Paints and Coatings industries as well due to its physical properties such as whiteness, oil absorption and loss on ignition fit the needs of building materials industry. In this case the powder could release trace mineral elements.

Tourmaline powder is non-toxic, tasteless and containing rich mineral elements, it is used in cosmetics industry for filler purpose such as facial masks and skin care products nowadays.
