3M™ Thinsulate™ Acoustic Insulation SM200L

Q: How does SM200L compare to other Thinsulate products?

SM200L is optimized for automotive and industrial noise reduction where weight and compressibility are critical. It balances strength, durability, and acoustic control.

Q: Can I request custom shapes for my assembly line?

Absolutely. We offer die-cut and kiss-cut formats , designed to streamline installation.

Q: Is the material water-resistant?

Yes. The hydrophobic polypropylene fibers prevent water absorption, minimizing odor and mildew risk.

Q: What is the maximum operating temperature for SM200L?

It is suitable up to 120°C continuous exposure and tested to 462°C for 2000 hours .
