TPS EP-12®

Expanded Perlite

TPS EP-12® is a high-temperature and durably hydrophobic expanded perlite pipe and block insulation manufactured by United Perlite Corporation, 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 C610.

High Temperature Protection

Engineered to protect industrial piping and equipment operating continuously at temperatures up to 1200℉ (650℃).

Well Documented CUI Protection

Two-pronged approach for superior corrosion under insulation (CUI) protection. Durably hydrophobic and contains integral inorganic silicate chemistry to inhibit CUI.

High Strength

The unique nature of perlite ore mined in the Philippines allows for very high compressive and flexural strength along with excellent abrasion resistance and reduced friability.
