Product Application:

1.Applied to Multi-layer Copper-clad Laminates:

①Improve Dimensional Stability:

Dimensional stability is crucial in the production and use of copper-clad laminates. The H series precipitated barium sulfate particles of Yunfu Hongzhi New Materials Co., Ltd. are uniform and fine, which can be uniformly dispersed in the resin matrix of the copper-clad board, reducing the size change rate of the board under different temperature and humidity conditions and improving the size stability of the copper-clad board.

②Enhance Heat Resistance:

Copper clad laminates are subject to certain heat effects in electronic devices and require good heat resistance. The H series precipitated barium sulfate from Yunfu Hongzhi New Materials Co., Ltd. has a high melting point and thermal stability, which can improve the heat resistance of copper-clad laminates to a certain extent, enabling them to maintain good performance in high-temperature environments.

③Improving Electrical Insulation Performance:

As an inorganic filler, the H series precipitated barium sulfate from Yunfu Hongzhi New Materials Co., Ltd. has excellent insulation properties. Adding it to the copper-clad laminate can fill the pores and defects in the resin matrix and reduce the conduction path of electrons in the board, thereby improving the electrical insulation performance of the copper-clad laminate and reducing the mutual interference and leakage risk between circuits.

④Improve Mechanical Strength:

The H series precipitated barium sulfate from Yunfu Hongzhi New Materials Co., Ltd. has a high hardness. Adding it to copper-clad laminates can enhance the mechanical strength of the board, allowing it to withstand greater external forces and pressures. For example, in the lamination process of multi-layer copper-clad laminates, H series precipitated barium sulfate can enhance the interlayer bonding force and overall strength of the board.

2.Application in Lithium Battery Separator Coating:

①Improve the uniformity of membrane pores, enhance the mechanical properties and thermal stability of polymer membranes, and improve their stability during use.

②Improve the electrolyte absorption rate and electrochemical stability of the diaphragm coating.

③X-rays can be used to detect product defects in the production process of diaphragms, improving automation efficiency.

④Reduce interface resistance.

3.Applied to Lead-Acid Batteries:

The H series precipitated barium sulfate from Yunfu Hongzhi New Materials Co., Ltd. is inert and used in lead-acid batteries, which can greatly delay the passivation of the battery cathode and improve the service life of the battery.

4.Applied in Coatings and Inks:

The H series precipitated barium sulfate from Yunfu Hongzhi New Materials Co., Ltd. is more easily dispersed in coatings and inks and can maintain quality stability (good dispersibility) even after long-term storage. It can be stirred and dispersed using a high-speed disperser with low equipment configuration requirements.
