(1) Avoid rain, moisture, and mechanical damage during transportation; (2) Store in a dry, well-ventilated indoor environment, away from fire sources; (3) Stack the panels flat and not too high to prevent deformation under pressure; (4) Avoid contact with chemical solvents, oil stains, etc.

The fire resistance test requires verification through both the oxygen index method and the vertical burning test. The testing agency will place the sample in an oxygen index tester, gradually reducing the oxygen concentration until the flame is extinguished, while recording the burning rate and smoke density values ​​to ensure that the product meets the fire resistance rating B1 requirements of GB 8624-2012.

They must meet the national standard GB 18580-2001, grade E1 requirement, with formaldehyde emissions ≤0.05mg/L. Some government procurement projects require compliance with national grade E1 or higher environmental standards.

Yes. As an interior decoration material, polyester fiber acoustic panels require a third-party testing report proving that their VOC emissions are below the LEED v4.1 standard limit to be included in the "low-emission materials" score. The product itself is made of environmentally friendly polyester fiber, which aligns with the development direction of green building materials.

Acoustic performance testing is typically conducted according to GB/T 20247-2006 "Acoustics—Measurement of Sound Absorption Properties of Materials by Reverberation Chamber Method," or alternatively according to international standards ISO 354 or ASTM C423. It is recommended to choose a third-party testing organization with CMA and CNAS accreditations to issue the test report.

Polyester fiber decorative sound-absorbing panels comply with the building materials industry standard JC/T 2704-2022. This standard was released on September 30, 2022, and came into effect on April 1, 2023. It specifies the product classification, specifications, technical requirements, test methods, and inspection rules. Based on sound absorption, they are divided into three levels: Level 1, Level 2, and Level 3.

Flame-retardant properties can be customized, enhancing safety while maintaining aesthetic appeal.

Full customization available for patterns, logos, edges and packaging.
