Recently, the ZZY2016 acoustic nonwoven (sound-absorbing paper)—a core product of Silence Tech Acoustics—successfully passed authoritative testing by SGS and fully complies with all specifications of the national environmental protection standard HJ 2546-2016, “Technical Requirements for Environmental Labeling Products—Textile Products.” Test results confirm that the product contains zero formaldehyde and exhibits zero heavy metal leaching. Its environmental performance far exceeds general industry standards, providing a robust safeguard for end-users’ safety while driving the upgrade of environmental quality in the acoustic noise-reduction materials industry and setting a new benchmark for green production in the sector.
It is reported that HJ 2546-2016 is a national-level mandatory environmental protection standard for textile products issued by China’s Ministry of Ecology and Environment. It replaces multiple previous industry standards and sets comprehensive and stringent standardized requirements for the control of hazardous substances, production processes, environmental performance, and safety indicators, covering the entire life cycle from raw material selection to production, processing, and finished product testing. It serves as the core authoritative standard for evaluating the sustainability, safety, and environmental friendliness of textile products, as well as a key certification basis for high-quality, eco-friendly products in the industry. The standard places particular emphasis on strictly controlling harmful components such as formaldehyde, heavy metals, carcinogenic dyes, and sensitizing substances. Passing this comprehensive testing indicates that a product’s environmental and safety performance has reached the highest domestic standards.
The SILENCE TECH ZZY2016 acoustic nonwoven submitted for testing is the brand’s flagship product, developed through its deep expertise in the field of acoustic noise reduction. Thanks to its excellent sound-absorption and noise-reduction properties, lightweight and convenient material characteristics, and wide range of applications, it is widely used in various fields, including interior decoration, noise reduction in household appliances, rail transport, and the optimisation of office spaces. To ensure product safety and quality, the brand consistently adheres to a rigorous production control system, implementing strict monitoring of hazardous substances at every stage—from raw material selection and production process optimisation to final product inspection. Following comprehensive testing and verification by the professional organisation SGS, no harmful substances such as formaldehyde, lead, mercury or cadmium were detected in this product model, which fully complies with the highest environmental protection requirements of the HJ 2546-2016 standard.
At present, the quality of products in the sound-absorbing and noise-reducing materials market varies considerably. Most similar products merely meet basic usage standards and fall short in terms of the control of harmful substances and environmental performance; some products pose potential risks due to trace amounts of formaldehyde and heavy metal residues, which, if used over the long term, may have adverse effects on the living environment and human health. Compared with standard products in the industry, Silence Tech acoustic nonwoven has achieved a significant leap forward in environmental performance thanks to this authoritative certification. It has completely eliminated the safety drawbacks associated with traditional noise-reduction materials, ensuring that it is truly non-toxic, harmless, eco-friendly, safe and healthy.
For end customers, this authoritative testing and certification provides robust assurance regarding the safe use of the product. Whether for domestic home improvements, commercial fit-outs or use in industrial equipment, the product can be safely integrated into any application, effectively addressing users’ key concerns regarding the environmental friendliness and safety of noise-reduction materials. This enables customers to purchase and use the product with complete peace of mind, significantly enhancing both the user experience and the product’s suitability for various applications.
At an industry level, the results of this certification represent a significant step forward in promoting the standardisation and green development of the acoustic noise-reduction materials sector. As a leading brand in the industry, SILENCE TECH has driven product upgrades by adhering to stringent national and international testing standards, thereby breaking through the sector’s long-standing tendency to prioritise noise-reduction performance over environmental protection and safety, and redefining the environmental quality standards for sound-absorbing non-woven fabrics. At the same time, it provides an excellent reference model for product research and development and quality control among industry enterprises, guiding the sector towards iterative upgrades characterised by high performance, zero pollution and full environmental sustainability, thereby helping the entire noise-reduction materials industry to improve quality, enhance efficiency and develop in a standardised manner.
Looking ahead, SILENCE TECH will continue to focus on the core field of acoustic noise reduction, adhering to its development philosophy of ‘quality first, green innovation’. The company will continue to dedicate itself to the research, development and innovation of environmentally friendly noise-reduction materials, constantly optimising production processes and enhancing product quality. By consistently relying on authoritative testing standards to refine high-quality products, SILENCE TECH aims to provide the market with more safe, environmentally friendly and efficient acoustic noise-reduction solutions, thereby contributing to the optimisation of living environments and promoting green, high-quality development within the industry.
