Elastic rubber foam products with excellent acoustic performance. And play a role in the barrier of sound waves (transmission loss); its environmentally friendly non-fiber, no odor, no dust, antibacterial and mildew and easy to install features for the user to bring great convenience products to achieve the insulation performance and acoustic performance of the excellent integrated performance, to meet the relevant application areas of the norms and standards, not only for air conditioning ducts, but also for other vibration-induced noise to play a damping, damping effect. With other materials such as perforated panels, aluminum panels and other composite modules will have a better effect. 
Acoustic absorption: open pore structure combined with composite pore design to achieve effective absorption of airborne sound over a wide frequency band; unique combination of physical properties maximizes absorption at key noise frequencies (α ≥ 0.9 absorption coefficient at 1000 HZ or above);
Transmission loss: the relatively high density and high flow resistance provide an effective barrier to sound waves;
Damping characteristics (vibration damping effect): good viscoelastic properties can effectively reduce or eliminate the resonance of the metal plate structure (such as soundproof enclosure, pipe walls, etc.), as a way to reduce the structure of the radiated noise.
Convenient Installation: Directly glued, easy to fit with the inner wall of the duct, the corner position can also be completely fit, no need to use other fixing methods, simple cutting of materials.
Health and environmental protection: no fiber, no dust particles, no formaldehyde, low VOC S emissions.
Anti-mold and anti-bacterial: Anti-bacterial and anti-mold factor is added to prevent the growth of bacteria and mold.
With good sound absorption and vibration damping performance, APEX (APEX) mute adiabatic slow rebound rubber material than the density of the traditional fiber-based material weighted sound insulation is higher than 5db, fit the inner wall of the air duct can improve the sound insulation of the air duct.
There are two ways to test our physical properties, one is to commission a third party company to carry out testing, such as SGS, TUV, BV and other companies to carry out testing services; the second way is through our own laboratory testing, which is also our daily use of the most frequent testing methods. Since the establishment of the factory, we have continuously invested in professional production and testing equipment, including two automatic auxiliary machine rubber mixing centers, two precision rubber mixing centers, four large foam vulcanization production lines, large coating machines, servo precision punches, vertical cutting machines, die-cutting machines, slitting machines, pipe making machines, embossing and laminating machines, and other professional equipment; The laboratory has complete testing equipment, including hazardous substance tester, electronic tensile machine, horizontal and vertical combustion meter, glow wire tester, lamp aging test chamber, vulcanizer, constant temperature and humidity tester, initial viscosity tester, viscosity retention tester, thermostat, density balance, Analytical balance, etc.
We have a warehouse and processing center for foamed products in the Qingdao Economic Development Zone, 10 km from the port of Qingdao. In this processing center, we can realize gluing, die-cutting, slitting, roll-cutting, punching, rolling and packing. We have supplied a large number of foamed products to manufacturers of refrigerators, washing machines, air-conditioners, etc. We are also very familiar with the performance requirements of various industries and can provide advice and solutions to our customers.
The characteristics of foamed rubber products lead to a high proportion of the cost of packaging and transportation. Therefore, reasonable packing method and rich experience in loading container are the factors that purchasers need to focus on. For the sheet material, we carry out the packaging of recyclable plastic bag with full consideration of compression deformation; for the expensive silicone products, or irregular engineered foamed products, we use carton packing to avoid the damage during transportation.

Can I get samples of different densities?
Yes, we provide A4 size samples, the samples are free of charge, you just need to provide the courier account number to arrange the transportation. Samples of special colors will take longer to prepare and there will be a charge.
Can I buy small quantities?
There is no problem at all, we will account for all the costs incurred in production and transportation according to your size and quantity, and when we reach an agreement on the additional costs, we can produce small orders for you. We can reduce this extra cost if you can buy multiple models of foamed products at the same time.
Can you use carton box packaging?
Yes, we can customize your cartons, including logos and text printed on the cartons. According to the density of EPDM foam board, we will calculate the size of each carton to reduce the size of individual carton, of course, double corrugated design is a must.
Can you offer cutting or die-cutting services?
Of course, very happy to provide you with this service. Please provide us with drawings and dimensional requirements, as well as performance specifications, and we will price them. We can also sign an NDA if you require. For packaging, we will also customize the packaging solution according to the size and shape of the product.
