3M™ Thinsulate™ Acoustic Insulation RS2400I

3M™ Thinsulate™ RS2400I is a non-woven, dual-scrim acoustic insulation designed specifically for harsh automotive environments, such as engine bays and wheel arch liners. This innovative material provides superior sound absorption, excellent fluid resistance, and durable thermal performance up to 120°C. Thanks to its dual black scrim and embossed surfaces, it offers both abrasion protection and secure adhesion points.

At EKO-TECH, we bring this premium insulation material closer to your specific needs. Through expert converting services such as rewinding, slitting, sheeting, die-cutting, and laminating with 3M adhesives, we transform RS2400I into application-ready formats – with fast turnaround and precision.

Where RS2400I Excels

3M™ Thinsulate™ RS2400I is ideal for a wide range of demanding automotive acoustic insulation applications, including:
