Heating, Venting, and Air Conditioning

Desiccant Bags

These desiccants are best when relative humidity is at least 40%.

Indicating Desiccant Bags

Know when it's time to change these desiccants—they turn from blue to pink after absorbing 8% of their weight.

Indicating Bulk Desiccants

Know when it's time to reactivate these desiccants—they turn from blue to pink after absorbing 6% of their weight.

Bulk Desiccants

Reactivate these desiccants after use by heating them.

Rechargeable Small-Space Dehumidifiers

Place these dehumidifiers in small spaces to protect moisture-sensitive materials such as photo lenses or 3D printing filaments. While they don’t need a battery or power cord during use, you do plug them in to dry them out—unlike other desiccants, they don’t require an oven.

Desiccators

Protect material from moisture by storing them in these desiccators.

Acid-Resistant Silica Insulation Sheets for Furnaces

Commonly used in furnaces and engine compartments, these flexible silica fiber sheets resist corrosive acids.

Ultra-Thin Low-Temperature Aerogel Pipe Insulation

Able to withstand temperatures as low as -290° F, these super-thin, lightweight sheets are made of fiber-reinforced silica aerogel that can flex into tight spaces other insulation can't. Use in process piping and power-generating applications.

Ultra-Thin Aerogel Pipe Insulation

Lightweight and super thin, these fiber-reinforced silica aerogel sheets and strips flex into tight spaces other insulation can't. Use on process piping and in power-generating applications.

Raw Materials

Flexible Silica Fabric Sheets and Strips

More flexible than standard silica fabric, wrap these sheets and strips to insulate pipes, wires, and hose. This fabric also protects against welding spatter.

Silica Fabric Sheets

Commonly used as curtains, covers, insulation, and splash shields, these sheets protect against welding spatter.

Chemicals

From acid to xylene, these dry and liquid chemicals are useful in a wide range of industrial applications.

Tough Corning® Gorilla® Glass

Very thin yet extremely durable, this glass has been chemically strengthened to maximize toughness and scratch resistance. It's often used for mobile device screens.

Super-Flexible Corning® Willow® Glass

This glass bends like plastic but is eight times harder—it’s harder than tooth enamel but softer than quartz.

Silica High-Temperature Sleeving

With a temperature rating of 1800°F or higher, this sleeving can withstand hotter temperatures than fiberglass and most ceramic.

Ultra High-Temperature Rope Edge Seals

Square-Profile Ultra
High-Temperature Rope Edge Seals

The flat edges on these square-profile seals provide more sealing surface than round-profile seals. They’re made of 98% silica to resist temperatures up to 2300° F.

Round-Profile Ultra High-Temperature Rope Edge Seals

Made of 96% silica, these seals resist temperatures up to 1800° F.

High-Temperature Casting Compounds

Choose from compounds that withstand 2700°, 3000°, or 4000° F.

Grease

Moisture-Resistant Grease

Formulated to adhere to metal parts and stay in place in wet environments, this grease is commonly used in pulp and paper manufacturing and water management facilities.

Seal and O-Ring Grease

Apply directly to seals and O-rings to extend service life by preventing drying and cracking.

Moisture-Resistant Seal and O-Ring Grease

Thickened with silica, this heavy grease clings to parts so it won't wash off in wet environments.

Food Industry Grease

For use in food-processing and preparation areas, this grease is rated for incidental contact with food.

Vacuum Seal and O-Ring Grease

A firm consistency and resistance to evaporation make this grease ideal for vacuum applications, such as flow meters, vacuum and pressure systems, and laboratory equipment.

Food Industry Seal and O-Ring Grease

This grease meets NSF/ANSI Standard 51 and FDA 21 CFR 175.300 for direct contact with food and NSF/ANSI Standard 61 for use with components that come into contact with drinking water.
