These materials are designed to withstand extreme temperatures, aggressive chemicals, and challenging environments, making them suitable for critical service seals in various industrial applications.

Product Specifications

THERMICULITE® 815 Tanged Sheet: Reinforced with a 316 stainless steel tanged core, available in various thicknesses and sizes. Suitable for temperatures from cryogenics to 1800°F (980°C) and pressure classes 150 to 300.
THERMICULITE® 835 Spiral Wound Filler: Used in spiral wound gaskets, compatible with a wide range of metals. Operates under the same temperature range as the 815 and supports pressure classes 150 to 2500.
THERMICULITE® 845 Flexpro™ Facing: Designed for kammprofile gaskets with various metallic core materials, supporting similar temperature and pressure ranges as the 835.

Thermiculite 715 Features
Thermiculite 715 is a coreless gasket material offering superior temperature and chemical resistance, fire safety, and non-contaminating properties. It is a cost-effective alternative to traditional materials like fiber, graphite, and PTFE.

Performance Comparison
Thermiculite 715 outperforms conventional gasket materials in chemical resistance, fire safety, oxidation resistance, purity, gasket integrity at temperatures above 500°F, and saturated steam compatibility.
