The day passed, Feiyang Optical was silent.

Two days have passed, but Feiyang Optical still has no movement.

A week has passed, and Feiyang Optical still has no movement.

Apart from the four affiliated companies, practitioners in the optical materials industry began to wonder what the Feiyang Optical Gour sells.

King of Materials, Tianfeng Chemical, Tianle Materials, and the initiator who jointly banned the three companies were also confused and didn't know what to do next.

They stuck the export of electronic-grade PI films, and Feiyang Optics did not purchase electronic-grade PI films anymore. It seems that their sanctions played a very effective role. However, the purpose of sanctioning Feiyang Optics does not allow it to obtain electronic-grade PI film raw materials is not the purpose, but the purpose is to directly kill Feiyang Optics.

But now, Feiyang Guangxue is not dead or speaks, as if he is completely unaware of the sanctions.

One punch hit the air, which was something that made them wonder and even depressed anyway.

In addition, whether it is Feiyang Optical, Zhongwei, Hualong, Diguang, and Qianjia, the confidentiality work is done quite well. They can't find out what Feiyang Optical is doing for a while.

It’s not that no one suspects that Feiyang Optics is working hard to develop electronic-grade PI films, but it is really unlikely that this idea will be left behind as soon as it was born.

Feiyang Optics, which has just been established not long ago, does not have the R&D capabilities.

Other domestic companies have not had the true mass production of electronic-grade PI films after development over the years.

"Have they given up?"

"No, I have reason to suspect that their country has made great efforts to help them develop."

"You can't take it lightly, you must continue to follow up and investigate!"

...

Tianfeng Chemical, Tianle Materials and King of Materials met and held a brief meeting and decided to continue to follow up, not giving Feiyang Optical a chance to breathe.

Nanjiang County, Feiyang New Materials.

"Boss, look at this report, it's amazing! The pi film has the best performance under the material ratio and process parameters. Look at its temperature range, from low temperatures of more than 100 degrees to high temperatures of more than 600 degrees, and the performance changes are not large. Moreover, the low temperatures of more than 100 degrees are still the result of our tests of experimental equipment. I believe that if there are lower temperatures of more than 100 degrees, its low temperatures of more than 100 degrees will be lower..."

During these days of peace in the industry, Jiang Xinyi, in accordance with Zhou Feiyu's instructions, prioritized the performance tests of various PI films produced, and the results far exceeded her imagination.

As soon as she got the test report, she was shocked, and then fell into great excitement. She rushed to the office and reported the good news to Zhou Feiyu.

"I'll take a look!"

Zhou Feiyu, who was busy studying, couldn't hear what Jiang Xinyi was breathless, but he heard it was good news, so he quickly stood up from his position, snatched the test report on Jiang Xinyi's hand and started reading it.

"The product performance does not change under low temperature liquid nitrogen at minus 196℃. The product performance does not change under high temperature test chamber 180℃."

"This is not the actual temperature range of product performance. There is no equipment test for low temperature tests. There is a test for high temperature tests to burn the product with alcohol lamp flames. The actual observation results show that the product performance does not change much. The flame temperature of alcohol lamp flames is about 600-700℃."

"The product elastic modulus reaches 15gpa, which is an extremely amazing data!"

"The expansion coefficient of the product is extremely low and it almost does not deform at high temperatures below 300℃."

"The product's dielectric performance constant is about 2.0, which is much lower than the imported electronic-grade pi films. "

...

"It's pretty good, this performance is more in line with my design."

Looking at the excellent performance results in the test report, Zhou Feiyu compared the performance parameters of excellent PI films in "Intermediate Film Technology". Although there are still some gaps, his goal is basically met.

In addition to excellent design, the performance of any product also lies in the two core cores of excellent raw materials and exquisite production technology.

At present, the raw materials and process level that Feiyang New Materials can obtain, and the pi film produced have achieved the current test results, which has already made Zhou Feiyu very satisfied.

At this stage, we cannot be overly demanding.

"Boss, I think this performance parameter is a striking foreign electronic-grade PI films. You are so amazing, really, the first time I have seen such a powerful material R&D personnel as you are."

After a long time, Jiang Xinyi still couldn't hide her excitement. She couldn't stop her shock and admiration for Zhou Feiyu's "strong material research and development capabilities."

If possible, she would like to say, "My admiration for you is like the endless river, and the Yellow River is flooding and out of control."

To be honest, the reason why she promised Zhou Feiyu to come to work was not for anything else, nor for seeing what raw materials for mobile phone glass in Zhou Feiyu could develop. She only has one real idea, that is, to go home with her husband Xiao Jianguo, work from home, and take care of the family.

Although she was surprised, she was not very concerned about the powerful performance of the fy-01 material developed by Zhou Feiyu, because she didn't know much about this.

It was not until Zhou Feiyu became a billionaire with the material of fy-01 that she was suddenly surprised that her husband's old classmate was so awesome!

Later, Zhou Feiyu took her and Zeng Taikun to develop PI films. Although she had some confidence in Zhou Feiyu because of the material FY-01, she was not very confident.

It was not until Zhou Feiyu did it himself, and she and Zeng Taikun developed it personally, that she believed in her profound material knowledge and strong craftsmanship skills.

Now that the PI film performance test report they developed by themselves came out, Jiang Xinyi was already impressed and looked at Zhou Feiyu with Jing Xing and Jing Zhi.

Listening to her words, Zhou Feiyu was also very happy, but only a faint smile appeared on his face, and waved his hand and said, "Low-key, low-key, where is it?"

Jiang Xinyi rolled her eyes and wanted to complain, but in the end she swallowed all the complaints.

As the boss, she is good at everything, but she is too modest, and even a little too much. She looks not as modest, but pretends to be x.

"Boss, I think we can promote this material."

Finally, Jiang Xinyi suggested.

Zhou Feiyu nodded and agreed: "You are right, then start with the mobile phone glass industry. My idea is that you will be responsible for the technical support of the application of fy-02 series materials in the mobile phone glass industry in the future."

Jiang Xinyi smiled and said, "Fe, I can do this."

Afterwards, Jiang Xinyi went out and couldn't wait to start the promotion work.
Chapter completed!
