Dynamat 11902 Dynacore 25mm Thermo-Acoustic Insulation One 813mm x 1372mm Sheet Dense Black Fibre Core Heat Resistant to 177°C UL94 MVSS 302 UL HF1 UL HBF Compliant 1.11sqm Coverage
The Dynamat 11902 Dynacore is one 813mm x 1372mm (32" x 54") sheet of 25mm thermo-acoustic insulation with a dense black fibre core. 1.11sqm (12 sq ft) of coverage. Absorbs low and mid-frequency sound, provides thermal insulation, and withstands temperatures up to 177°C (350°F). Lightweight, flexible, and compressible. UL94, MVSS 302, UL HF1, and UL HBF certified.
Product overview
The 11902 is the thicker version of Dynacore at 25mm (1"), providing greater acoustic absorption and thermal insulation than the 12mm 11901 in applications where panel clearance allows for the additional thickness. The dense black fibre core structure absorbs low and mid-frequency sound energy across vehicle interiors and other applications requiring noise and heat management. Dynacore is lightweight, flexible, and compressible for straightforward installation on curved and irregular surfaces. Heat resistance up to 177°C (350°F) confirms suitability for firewall, under-hood, and engine bay applications in addition to standard interior panels. Certified to UL94, MVSS 302, UL HF1, and UL HBF safety standards.

Frequently asked questions
What is the difference between the Dynacore 11902 and the 11901?
The 11902 is 25mm (1") thick. The 11901 is 12mm (1/2") thick. Both share the same 813mm x 1372mm sheet size and 1.11sqm coverage. The thicker 11902 provides greater acoustic absorption and thermal performance where panel clearance allows for it.
What is Dynacore and how does it work?
Dynacore uses a dense black fibre core that absorbs low and mid-frequency sound energy, converting it into negligible heat energy rather than reflecting or transmitting it. This makes it effective for reducing engine noise, road noise, and other low to mid-frequency sources entering the vehicle cabin.
Is the 11902 suitable for under-hood and firewall applications?
Yes. With heat resistance up to 177°C (350°F), the 11902 is suited to firewall, under-hood, and engine bay applications in addition to standard interior panels including floors, doors, and roofs.
Can Dynacore be used with Dynamat Xtreme?
Yes. For maximum performance, Dynamat Xtreme is applied to the bare metal panel first to damp vibration, and Dynacore is applied on top for acoustic absorption and thermal insulation.
What safety standards does the 11902 meet?
The 11902 is certified to UL94, MVSS 302, UL HF1, and UL HBF. MVSS 302 is the US federal motor vehicle safety standard for the flammability of interior materials, confirming Dynacore is suited for automotive interior use.
