This material is a patented technology of utility model. Is the product made of this material infringing?

Article 11 of the Patent Law After the patent right for inventions and utility models has been granted, unless otherwise provided for in this Law, no unit or individual may exploit the patent without the permission of the patentee, that is, may not manufacture, use, promise to sell, sell or import its patented products for production and business purposes. ...

If your materials are not purchased from the patentee or from a company or enterprise authorized by the patentee, it is strictly infringement for you to use the patented product for commercial purposes. If you can provide proof that your materials were purchased through formal channels, you can avoid compensation, and the responsibility lies with the merchants who illegally provide you with materials.
