Polyurethane Vibration & Sound Isolation Pad - China Suppliers & Factory for Noise Control in Recording Studios

,

Introducing our advanced acoustic solution, expertly designed for recording studios, KTV rooms, theaters, cinemas, and opera houses. Perfect for both new and renovated independent spaces, this product effectively controls both impact and airborne noise.
Our innovative acoustic principle incorporates elastic materials and open-cell structures, which absorb and reflect sound energy, significantly reducing sound transmission. The perforation rate and pore size have been meticulously engineered for optimal sound performance.
Achieve outstanding noise reduction with our product, which effectively blocks impact noise across the entire frequency range, offering sound insulation greater than or equal to 17 dB.
Our manufacturing process employs continuous casting, ensuring high-quality durability and environmental resistance. This material is resistant to corrosion, acids, alkalis, and oils while also being mold-proof, insect-proof, and age-resistant. It can withstand service temperatures ranging from -20°C to +90°C.
With an impressive service life exceeding 60 years and requiring no maintenance, our acoustic solution offers exceptional longevity. The high flexibility of our product allows for tight bonding with concrete slabs, preventing any hollow spots or deformation during installation.
The load performance is remarkable, providing uniform stress distribution under both static and dynamic loads without any loss of thickness, and boasts a load capacity up to 5 t/m².
Available in a thickness range of 2–30 mm, our product also meets flame retardancy standards of at least B1.
Complying with GB50118-2010, HG/T5328-2018, as well as in-house enterprise standards and client specifications, our acoustic solution is supplied by reliable China suppliers and manufactured in our state-of-the-art factory. Elevate your sound environment with our superior acoustic solutions today!

    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.
