Does the conference room sound insulation board contain formaldehyde?

With the improvement of quality of life, noise pollution has become an important factor affecting the comfort of living. As a widely used sound insulation material in decoration, sound insulation panels are favored by the market for their excellent sound insulation effect. However, while paying attention to sound insulation performance, the issue of formaldehyde emission has also caused widespread concern among consumers.

Does the sound insulation board used indoors contain formaldehyde?

The answer is yes. The formaldehyde in indoor soundproof panels mainly comes from two sources:

The material defects of synthetic boards: Some sound insulation boards use artificial boards (such as MDF and multi-layer boards) to increase thickness or reduce costs. These boards may be bonded with urea-formaldehyde resin with high formaldehyde content. The higher the density of the board, the greater the amount of glue, and the corresponding increase in the risk of formaldehyde release.

Formaldehyde residues in adhesives: The adhesives used in the synthesis process of sound insulation boards are the main carriers of formaldehyde. Formaldehyde in inferior adhesives will be slowly released during long-term use, and the release rate will accelerate especially in high-temperature and high-humidity environments.

How to deal with excessive formaldehyde in soundproof panels?

1. Control from the source: choose regular brands and environmentally friendly products

Priority is given to brands with professional qualifications, such as Earppie Sound Insulation, which has been deeply involved in the field of sound insulation materials for many years. As a benchmark enterprise focusing on environmentally friendly acoustic materials in the industry, Earppie Sound Insulation always regards formaldehyde control as the core standard of its products:

Material innovation: using E0-grade environmentally friendly substrates (such as glass magnesium plates without formaldehyde addition, aviation-grade damping materials) to reduce formaldehyde emission sources from the source;

Process upgrade: Abandoning traditional urea-formaldehyde resin adhesives, food-grade environmentally friendly hot melt adhesives or water-based adhesives are selected. According to the test by the National Building Materials Testing Center, the formaldehyde emission of the sound insulation board is as low as 0.02mg/m³, which is far lower than the national standard (0.124mg/m³ specified in GB 18580-2017 "Limit of Formaldehyde Emission from Wood-based Panels and Their Products for Interior Decoration and Renovation Materials");

Full-process control: From raw material procurement to finished product delivery, each batch of products undergoes testing in a CNAS-accredited laboratory and is accompanied by a formaldehyde emission test report, ensuring that consumers can trace the environmental performance of the products.

2. Professional treatment before and after installation

Pre-installation pretreatment: If conditions permit, the sound insulation boards can be placed in a well-ventilated environment to air out for 3-5 days to accelerate the volatilization of residual formaldehyde. For Earppie sound insulation boards, since their formaldehyde emission is extremely low, this step can further reduce the initial emission.

Targeted formaldehyde treatment: For high-density sound insulation boards, conventional agents are difficult to penetrate. It is recommended to use nano-scale photocatalyst formaldehyde removal reagents (such as Earppie's independently developed nano-titanium ion catalytic spray). Its particle size is less than 5nm, which can penetrate into the micropores of the boards to decompose formaldehyde, with a decomposition rate of over 92%, and it does not affect the performance of the sound insulation boards.

Whole-house ventilation and auxiliary measures: After installation, keep the indoor ventilation continuous, use air purifiers (choose models with formaldehyde decomposition function), or place adsorption materials such as Maya blue and activated carbon in the corners (need to be replaced regularly) to reduce formaldehyde concentration in multiple dimensions.

Part 3.Earppie Sound Insulation: Double Guarantee of Environmental Protection and Performance

As an integrated sound insulation material solution provider encompassing R&D, production, and sales, Earppie Sound Insulation not only strives for excellence in formaldehyde control but also maintains industry-leading product performance:
