TPI 301 - Thermal and Acoustic
TPI 301 is used as thermal and acoustic insulation aboard military naval and commercial vessels as well as in rail applications. It's low off gassing properties also make it a superior choice for sensitive electronic, medical and analytical instruments.
TPI 301 Foam is utilised in marine, commercial and industrial markets as lightweight, fire resistant, thermal and acoustic insulation. Tons of topside weight can be saved by replacing fibrous glass insulation with Trelleborg Polyimide Foam. TPI 301 Thermal and Acoustic foam is used in a variety of applications including:-
- Marine hullboard
- Marine ceiling panels
- Hangar deck
- Beam and duct wrap
- Commercial HVAC duct liner
- Walls, roof and floor insulation in train carriages
- Joints and pipe shoes for cryogenic pipelines at olefin production and chemical facilities

- High temperature industrial
- Wind tunnels
- Electronic, medical and analytical instruments
- Extremely lightweight
- Superior fire resistance
- Outstanding thermal and acoustic properties
