3M™ Thinsulate™ SM600L

3M™ Thinsulate™ Acoustic Insulation SM600L

3M™ Thinsulate™ Acoustic Insulation SM600L is one of the thickest and most absorbent solutions in the Thinsulate range, engineered for superior noise damping in critical automotive and industrial applications. With a 42 mm thickness and 672 g/m² surface weight, SM600L delivers powerful acoustic energy absorption while remaining lightweight, hydrophobic, and flexible.

At EKO-TECH, we offer precision converting to adapt Thinsulate™ SM600L for your exact production needs. Whether you need custom-width rolls, sheeted formats, adhesive-backed panels, or die-cut pieces, we’re your one-stop partner for material processing and application design.

Where to Use SM600L

3M™ Thinsulate™ SM600L is ideal for:

  • Automotive interiors: door trim, dashboards, A/B/C pillars, headliners, package trays

  • Cargo compartments & trunk liners: floor and wall acoustic insulation

  • Wheel arch liners & bumpers: exterior noise absorption zones

  • Heavy-duty & specialty vehicles: agricultural equipment, buses, RVs, construction machinery

  • Moisture-prone environments: HVAC panels, appliance casings, where mold resistance is required

Why Choose 3M™ Thinsulate™ SM600L?

  • Exceptional sound absorption: thick construction absorbs high-energy noise efficiently

  • Lightweight with high performance: balances mass and acoustic efficiency
