TPS Phenolic Foam Pipe Insulation

Therma-Phen® Phenolic Foam Pipe Insulation

Therma-Phen® Phenolic Foam Pipe Insulation is a closed-cell, fire and moisture resistant thermoset foam plastic produced and fabricated by Fujian Tenlead Advanced Materials Co., LTD, imported exclusively by TPS and sold through their nationwide network of distribution partners.


Third party verified to meet or exceed all physical property requirements in accordance with ASTM C1126 Type III.

Excellent Thermal Protection

Engineered to protect piping in commercial and industrial facilities operating continuously at temperatures from -290℉ to 257℉. (Properly designed and installed vapor retarder components required for all below ambient systems)

Fire Resistant

Third-party tested per ASTM E84 and meets 25/50 flame spread/smoke developed code requirements for use within commercial building return air plenums (up to 2" wall thickness)

Moisture Protection

Closed-cell foam insulation with outboard vapor retarder provides excellent moisture resistance for below ambient systems operating in humid environments.

High Compressive Strength

Thermoset phenolic foam is available in several different densities and does not crush easily compared to products such as mineral fiber pipe insulations.

Quick Ship Fittings

TPS is now fabricating mitered fittings including 45-degree and 90-degree elbows and tees at both of our locations in Las Vegas, NV and Stanwood, WA. The ability to ship pipe cover and fittings on the same truck adds real value for our customers.
