Polyurethane Vibration & Sound Isolation Pads from China Suppliers | Factory for Acoustic Solutions

Introducing our high-performance acoustic panels, expertly designed for recording studios, KTV rooms, theaters, cinemas, and opera houses. These panels are ideal for both new and renovated independent spaces where control of impact and airborne noise is essential, Crafted with a unique acoustic principle, our panels incorporate elastic materials and open cells that effectively absorb and reflect sound energy, significantly weakening sound transmission. The optimized perforation rate and pore size ensure superior acoustic performance, Our noise reduction capabilities deliver impressive blocking of impact noise across all frequencies, providing sound insulation of ≥17 dB. The manufacturing process utilizes continuous casting forming, ensuring consistency and quality, These panels boast remarkable durability and environmental resistance, effectively resisting corrosion, acids, alkalis, and oils. Additionally, they are mold-proof, insect-proof, and age-resistant, with a service temperature range from -20°C to +90°C. Designed for longevity, they have a service life of over 60 years without the need for maintenance, Installation is simplified by the high flexibility of our panels, allowing tight bonding with concrete slabs and preventing hollow spots or deformation. They maintain uniform stress distribution under static and dynamic loads, with no thickness loss and a load capacity of up to 5 t/m², Available in a thickness range of 2–30 mm, our panels meet flame retardancy standards of ≥ BThey comply with GB50118-2010, HG/T5328-2018, as well as in-house enterprise standards and specific client requirements, As a trusted factory and supplier in China, we are committed to providing top-quality acoustic solutions that enhance sound environments in various applications

    Custmized Railway Ballast Vibration Reduction Mat EN Standard101

    Application

    Widely used across China’s rail network, the Elastic Ballast Mat delivers proven results. Installed under the ballast bed, it boosts track elasticity, cuts down ballast breakage, and improves load distribution—especially on curves and turnouts. Designed with a puncture-resistant top layer and an elastic damping layer, Ballast Mat performs reliably with or without retaining walls.

    Quality Assurance

    We have designed, manufactured, and exported ballast mats for over 20 years. Our products are installed on more than 40 metro lines across major Chinese cities like Beijing, Shenzhen, Wuxi. Customer satisfaction stands at 98%.
    number
    Before leaving our factory, the ballast mats will be tested strictly according to standard requirements . For customers who require more, we carry out type tests at our in-house testing centre. 

    Tests include:
    • Fatigue testing
    • Static and dynamic stiffness measurement
    • Tensile testing

    This process verifies Elastic Ballast Mat reliability under real working conditions.

    Production Capacity

    We handle Ballast Mat production in-house at our dedicated continuous foaming workshop. The facility runs on an automated German production line, giving us consistent quality and high output. Current annual capacity stands at 900,000 square metres of Railway ballast vibration reduction mat.

    Custom Mould Design & Manufacturing

    – In-House, Start to Finish
    Our Mould Engineering Department operates a full digital workshop equipped with more than 20 CNC machines, including machining centres, spark eroders, and wire cutters. This allows us to design and manufacture a wide range of moulds for the rail transit industry – injection moulding, rubber, SMC, and specialised types such as auto-core-pulling bush moulds.

    Annual output stands at 300 sets of moulds and tooling.

    If your project calls for a non-standard shape for Elastic Ballast Mat, a special material, or a unique production feature, we have the equipment and the experience to deliver.
