3M™ Thinsulate™ TC2303

3M™ Thinsulate™ Acoustic Insulation TC2303

The 3M™ Thinsulate™ Acoustic Insulation TC2303 is engineered to meet the automotive industry’s growing demand for lightweight noise reduction solutions. As one of the lightest NVH cavity-fillers in the 3M™ Thinsulate™ family, TC2303 combines exceptional acoustic absorption with versatile conformability, making it a go-to material for vehicle manufacturers focused on mass reduction and acoustic performance. TC2303 features a 27 mm thick web of PE and PP fibers, optimized to absorb mid- and high-frequency noise by converting sound energy into heat. The double-sided 100% polypropylene scrim ensures durability, while its embossing enhances abrasion resistance. From pillars to panels, this acoustic insulation is designed for seamless integration in modern vehicle interiors.

With precision converting services by Eko-Tech, we offer tailored formats of 3M™ Thinsulate™ TC2303 for every production need — from slitting and sheeting to die-cutting and lamination with advanced adhesives.

Benefits of 3M™ Thinsulate™ Acoustic Insulation TC2303

  • Ultra-Lightweight: With a density of just 7.7 kg/m³ and basis weight of 232 g/m², it offers outstanding mass reduction benefits.

  • Superior Acoustic Absorption: Optimized for NVH performance in mid to high frequencies.

  • Excellent Compressibility: Ideal for filling variable cavities with consistent performance.

  • Durable Scrim Protection: Reinforced on both sides with white polyolefin scrim for strength and fiber protection.

  • Moisture & Mold Resistant: No extra waterproofing layer needed, eliminating odor risks.

  • Effortless Installation: Supports ultrasonic welding, adhesives, or mechanical fastening.

  • Consistent Performance: Surface embossing ensures material integrity even in high-friction applications.

FAQ

Can Eko-Tech laminate TC2303 with adhesives?2025-07-07T12:27:11+02:00

Yes, we offer lamination with a wide range of 3M adhesives to meet your bonding and application needs.

How does TC2303 help reduce vehicle weight?2025-07-07T12:26:58+02:00

With its ultra-low density (7.7 kg/m³), TC2303 helps OEMs meet weight reduction targets without sacrificing acoustic performance.

Is the material moisture-resistant?2025-07-07T12:26:48+02:00

Absolutely. TC2303 is mold and moisture-resistant, so it doesn’t require an additional waterproofing layer.

Can TC2303 be die-cut into custom parts?2025-07-07T12:26:39+02:00

Yes, it is ideal for die-cutting, kiss-cutting, and sheeting — making it perfect for parts like door inserts, pillar trims, or headliner shapes.

What makes TC2303 better than traditional NVH materials?2025-07-07T12:26:29+02:00

It offers high acoustic absorption with minimal weight, better conformability for complex geometries, and is easier to install compared to fiberglass or felt.
