3M™ Thinsulate™ Acoustic Insulation TF1800

Q: What differentiates TF1800 from other Thinsulate™ materials?

TF1800 provides an optimal balance between mass, performance, and processability , specifically suited for applications where both noise control and weight are key.

Q: Can I order TF1800 in pre-cut or laminated format?

Yes. We offer rewinding, slitting, sheeting, die-cutting, and lamination using compatible 3M adhesives.

Q: Does TF1800 meet flame resistance standards?

Yes. It complies with FMVSS 302 , making it safe for automotive interiors.

Q: What are the technical properties of TF1800?

TF1800 has a basis weight of 185 g/m² and a density of 8.810 kg/m³ , with excellent compressibility and acoustic absorption.

3M™ Thinsulate™ Acoustic Insulation TF1800 delivers a reliable solution for automotive NVH challenges. Designed for filling cavities and suppressing structure-borne noise, TF1800 is a high-performance non-woven insulation mat that is lightweight, compressible, and easy to process. It features a basis weight of 185 g/m² and density of 8.810 kg/m³, making it ideal for manufacturers who prioritize mass reduction without compromising acoustic performance.

The product incorporates a durable polyolefin scrim on one side, reinforced with surface embossing to increase abrasion resistance and bonding reliability. As part of the Thinsulate™ TF Series, it’s tailored for irregular and tight spaces behind vehicle panels.

EKO-TECH, as your 3M Select Converter, makes TF1800 available in production-ready formats: rewound, slit, sheeted, kiss- or die-cut, and optionally laminated with 3M adhesives.

Where TF1800 Performs Best

TF1800 is engineered for interior acoustic management in automotive applications:

Door trim panels
Instrument panels
Body side and pillar trim
Headliners and roof structures
Parcel trays and trunk compartments
Wheel arch liners
Interior cavities and voids needing consistent acoustic fill

Its shape-conforming flexibility allows full contact with uneven surfaces, maximizing sound absorption.
