Every vehicle presents a unique acoustic and thermal challenge. Whether you manage a fleet, retrofit classic cars, or specify components for modern EVs, selecting the right material transforms perceived quality. ASLONG’s portfolio addresses the full spectrum of NVH (noise, vibration, harshness) and thermal control needs with products designed for real-world conditions.

Butyl Rubber Sound Damping Mat: High-density damping for doors, floors, trunks and roofs to reduce panel resonance and road noise.
Mass Loaded Vinyl (MLV): Thin, heavy barrier for blocking airborne noise and improving overall sound isolation where space is limited.
NBR Foam & Tire Silent Foam: Open- and closed-cell foams for thermal insulation, cushioning and targeted vibration absorption.
Sound White Cotton: Lightweight acoustic fill for cavities and headliners that balances reverberation without adding bulk.
Butyl Waterproof Tape & Electric Auxiliary Materials: Installation essentials that ensure long-lasting adhesion, moisture protection and electrical compatibility.

Each product is specified to work together: damping layers cut structural vibration, barrier layers block transmitted sound, and insulating foams manage heat flow and HVAC loading. The result is a quieter, more energy-efficient cabin and a measurable upgrade in perceived vehicle quality.

Performance, sustainability and application guidance

ASLONG’s approach blends practical application guidance with rigorous manufacturing standards. Founded in 2000, Welllink Guangdong New Material Co., Ltd. (ASLONG) has expanded from an R&D-led startup into a high-tech enterprise exporting to Europe, North America, Asia and Africa. Our manufacturing processes emphasize consistent quality control and environmentally mindful formulations—offering flame-retardant options and low-VOC products suitable for demanding automotive interiors.

When selecting materials, consider these practical criteria:

Application zone: floors and trunks need high-mass damping; headliners benefit from lightweight acoustic fills.
Thickness and density: higher density improves blocking; thickness affects fit and thermal resistance.
Adhesion and ease of installation: pre-backed butyl mats and waterproof tapes speed professional and DIY installs.
Environmental and safety specs: request datasheets for temperature range, flame class, and VOC performance for regulatory compliance.

For installers and specifiers, ASLONG provides technical datasheets, sample kits, and guidance to optimize product placement for measurable NVH improvements and reduced HVAC workload. We also support OEM and aftermarket channels: custom widths, roll lengths, and tailored formulations are available to meet specific vehicle requirements.

FAQ

What is automotive noise & heat insulation and how does it improve vehicle comfort?

Automotive noise & heat insulation combines damping layers, mass barriers and insulating foams to reduce structure-borne vibration, block airborne noise and slow heat transfer. Together these layers produce a quieter cabin, more stable interior temperatures, reduced HVAC load and improved audio clarity, which enhances perceived quality and passenger comfort.

Which ASLONG products are best for reducing road and engine noise?

For structure-borne road and engine noise, Butyl Rubber Sound Damping Mats are typically most effective because they reduce panel resonance. Mass Loaded Vinyl (MLV) is recommended where airborne noise blocking is needed in limited space. Combining damping mats on panels with acoustic fill (Sound White Cotton or NBR foam) in cavities yields the best overall NVH improvement.

Are ASLONG materials suitable for electric vehicles and extreme temperature ranges?

Yes. ASLONG formulates products for modern vehicle platforms including EVs; many offerings are rated for automotive temperature ranges and are available in flame-retardant and low-VOC versions for interior use. Specific temperature and safety ratings vary by product—request the technical datasheet for performance metrics and certification details relevant to your application.

Can I install ASLONG insulation products as a DIY project or should I use a professional installer?

Basic products like self-adhesive butyl mats and tapes can be installed by experienced DIYers with proper surface preparation, trimming and heat-assisted adhesion. For full-coverage projects, areas requiring seam sealing, or to achieve manufacturer-level results, professional installation is recommended to ensure correct placement, secure adhesion and long-term performance.

How can I order samples, request technical data, or become an ASLONG agent?
