ZINC OXIDE - 台灣堺股份有限公司

BARIUM AND STRONTIUM PRODUCTS

We are supplying superior quality products backed by our wealth of accumulated expertise and technologies.

We have been manufacturing zinc oxide since the company was founded. Zinc oxide is made from high purity electrolytic zinc, so it can be used in a wide range of applications from rubber and paints to plastics, electronic materials and cosmetics. In addition, our products have a great reputation for performance, such as
ultrafine products used as UV shielding agents in sun care cosmetics and large particle products used as heat-dissipation fillers in electronic parts.

Sakai Chemical Group’s Strengths

We offer a broad product lineup from nanosize particles to large particles.
Our technology of surface treatments provides higher dispersivity and other special functions.

■Optical characteristics of FINEX Series

Characteristics vary based on the particle size.FINEX-25 has high UVA shielding performance,and FINEX-50 has high transparency.

【FINEX-52W-LP2 TEM image】

Zinc oxide is densely coated by a sillica layer.

【Total light transmittance】

■High-Density Silica Coating (Inactive Grade)

Higher silica processing volume provides stronger suppression of photocatalytic activity.

high-density sillica coating

Different silica processing offers different activities (Vaseline discoloration test)

■Pressure resistance test

2MPa particles keep their shape even after pressing at 2MPa.

《Measurement conditions》

2g of test samples were placed in a 35mm diameter ring and compacted.

《Mesurement method》

Artitical sebum was mixed with test samples in centrifuge tubes,in the ratios shown above.
After being left to stand for 30 minutes,the mixtures were centrifugally separated,and the separated solvents were collected.
The solvents were measured using FT-IR to enable calculation of the peak area of 2045-2875 cm-1(C-H symmetric stretch vibration) derived form sebum.
Calibration curves were formulated in order to calculate the sebum absorption rate.The artificial sebum was produced by mixing oleic acid,squalene,and olive oil in a ratio of 1:2:2
