About Dayin PET Panels

A factory line for PET, from the same producer as Dayin Acoustics
This website is a dedicated product site for PET acoustic panels. It does not replace the broader Dayin Acoustics site. The company describes itself as a producer of sound-absorbing and sound-insulating materials, covering research, manufacturing, and supply for interior projects.
The 2026 catalog About page states that the company’s products are exported to more than 20 countries and are used in stadiums, theaters, classrooms, meeting rooms, recording and broadcasting rooms, hotels, and entertainment venues. Earlier company literature also notes more than 50 acoustic professionals, more than 30 acoustic patented technologies, annual output of various acoustic materials above 500,000 square metres, and that about 40% of products are exported.
The same 2026 About page lists a factory area of more than 10,000 m² and more than 11 years of production experience, which aligns with a 2014 founding date.
Testing and marks shown in the catalogs
The PET brochure includes SGS report thumbnails for E0 / formaldehyde, acoustic absorption (NRC described as reaching more than 0.8), and flame-retardant testing (Grade B1 on that overview). The product table on the same brochure lists fire resistance as Class B. CE, SGS, and GTS logos appear on the brochure back cover and on the 2026 catalog. We will supply the available reports that match a quoted specification; we do not attach grades here that are not written in those documents.
