ASLONG NBR Foam Sheets — Premium Sound & Shock Insulation

ASLONG NBR foam sheets deliver reliable, closed-cell nitrile rubber foam solutions engineered for sound insulation, thermal buffering, and impact damping across automotive, construction, industrial, and residential applications. Backed by Welllink Guangdong New Material Co., Ltd.'s two decades of R&D and a modern 10,000+ m² production base, these sheets combine consistent quality, environmental compliance, and customizable formats to meet global performance and installation needs.

Explore Our High Quality NBR Foam Sheets Collection

NBR (nitrile butadiene rubber) foam from ASLONG is designed to solve practical acoustic and mechanical challenges without adding complexity to your projects. Our sheets are manufactured as closed-cell foam, which makes them inherently resistant to moisture, oils, and many solvents — an advantage when products must perform reliably in vehicles, factories, and damp building cavities. The result is a versatile material that reduces airborne noise, minimizes vibration, and provides thermal insulation while remaining lightweight and easy to install.

Key highlights of the collection:

Available in multiple thicknesses and densities to match acoustic or shock absorption requirements.
Consistent cell structure for predictable performance in sealing and gasketing applications.
Cut-to-size, rolls, and sheet formats to support prototypes, small runs, and high-volume production.

Why ASLONG NBR Foam Sheets Matter to Your Project

Choosing the right foam isn't just a materials decision — it influences comfort, compliance, and lifetime cost. ASLONG approaches NBR foam with a product philosophy that balances performance, environmental responsibility, and manufacturability. Closed-cell nitrile foam reduces sound transmission in walls, partitions, ducts, and vehicle panels, while its resilience softens mechanical shocks and prolongs the life of assemblies. For integrators and specifiers, this means fewer callbacks, easier installations, and reliable acoustic outcomes.

Practical benefits you will notice:

Acoustic improvement: dampens mid-to-high frequency noise and complements mass-loaded layers for low-frequency control.
Durability: resists compression set and retains shape under repeated loading.
Installation-friendly: lightweight sheets adhere well with common adhesives and can be die-cut, slit, or water-jet cut for precision parts.

Applications, Compliance & ASLONG Assurance

NBR foam sheets from ASLONG are engineered to suit a wide range of industries — from automotive door panels, engine bays and trunk liners to HVAC duct lining, building acoustics, electronic enclosures, and sporting or protective equipment. Our experience exporting to Europe, North America, Asia, and Africa informs how we meet international expectations for consistency, packaging, and logistics.

ASLONG’s manufacturing and quality practices reflect our commitment to E-E-A-T principles: founded in 2000, the company pairs long-standing technical expertise with a modern production base of more than 10,000 square meters. We maintain process controls and testing protocols to verify density, tensile properties, closed-cell integrity, and flame-retardant grades where required. Customers benefit from engineering guidance, material datasheets, and the option to request samples or bespoke formulations.

Typical specifications and services available:

Thickness range: thin gasketing sheets to several centimeters for vibration isolation.
Density and hardness customization to balance acoustic and mechanical needs.
Adhesive-backed options, laminated assemblies, and coordinated supply with other ASLONG products (butyl damping mats, mass-loaded vinyl, sound cotton).

FAQ

What are the main properties of ASLONG NBR foam sheets?

ASLONG NBR foam sheets are closed-cell nitrile butadiene rubber foams known for moisture resistance, oil and solvent tolerance, good compressive recovery, and predictable acoustic damping in mid-to-high frequencies. They are available in a range of densities and thicknesses, and can be supplied in sheets, rolls, or die-cut parts to meet specific sealing, gasketing, or insulation needs.

Which industries and applications are best suited for these foam sheets?

NBR foam sheets are widely used in automotive (door panels, engine compartments, trunk liners), HVAC and building acoustics (duct lining, partition seals), industrial machinery (vibration isolation, gaskets), electronics enclosures (seal and cushion), and consumer products requiring lightweight shock absorption. Their moisture and oil resistance make them particularly suitable where exposure to fuels, lubricants, or humid conditions is expected.

How do I choose the right thickness and density for my project?

Select thickness based on the required gap fill and acoustic or mechanical isolation. Thinner sheets (1–5 mm) work well for gasketing and airtight seals; medium thickness (5–20 mm) suits general acoustic damping and cushioning; thicker sections are used for significant vibration isolation. Density affects stiffness and damping: lower density is softer and better for sealing, while higher density improves structural support and low-frequency damping. ASLONG can provide datasheets and sample panels to validate performance in your application.

Are ASLONG NBR foam sheets environmentally safe and compliant with standards?

ASLONG manufactures NBR foam with an emphasis on environmental compliance and consistent quality control. While specific regulatory certifications depend on the foam grade (e.g., flame retardancy, RoHS), we can provide relevant test reports and material declarations upon request. For projects with strict environmental or fire-safety requirements, consult our technical team to identify the appropriate formulation and documentation.

Can you supply custom sizes, adhesive backings, or cut-to-shape parts?

Yes. ASLONG supports customization including adhesive-backed sheets, laminated assemblies, precision die-cut parts, and bespoke thickness/density combinations. Our 10,000+ m² facility and production capabilities allow economical small-batch prototyping as well as high-volume manufacturing.
