Rigid Silica High-Efficiency Insulation Sheets for Furnaces
 |
Typically used in ovens and furnaces, these are the most efficient of our rigid high-temperature insulation sheets. Please note that they require special care when installing since the crumbly material is difficult to work with and will crack easily. Sheets lose strength over time and are intended to be installed behind another facing or insulation material. They resist damage from fire and moisture. Insulation performs best at temperatures above 1,000° F.

Square-Profile Ultra-High-Temperature Rope Seals
 |
The flat edges on these square-profile seals provide more sealing surface than round-profile seals. They’re made of 98% silica fiber for excellent temperature resistance. They’re flexible and will conform to uneven surfaces. Push them into the groove that’s commonly built into oven doors, furnaces, and tanks. They resist water, salts, and diluted acids.

Ultra-High-Temperature Flanged Rope Seals
 |
These seals have a strong Inconel core covered with woven silica fabric that’s been treated to withstand extremely high heat. They resist most refrigerants, salts, and grease. The flange on these seals slides into a slot that is commonly found on oven, furnace, and boiler doors; it can be positioned to cover large gaps.

Food and Beverage Electrically Insulating Grease
 |  |
Pail | Tube |
Use this grease in areas where there is the possibility of contact with food. Also known as dielectric grease, it lubricates and protects electrical systems. It resists water and corrosion. This grease can be used on most rubber and plastic.
Grease lubricates most efficiently below the maximum temperature.
1 NLGI Grade—NLGI 1 is about the consistency of tomato paste.
FDA Compliant 21 CFR 175.300—Grease that meets FDA Compliant 21 CFR 175.300 is rated for direct contact with food.
NSF Registered H1—Grease that is NSF Registered H1 is rated for incidental contact with food.
NSF/ANSI 51—Grease that meets NSF/ANSI 51 is rated for direct contact with food.
NSF/ANSI 61—Grease that meets NSF/ANSI 61 is certified for use with components that come into contact with drinking water.
Dielectric Strength—Dielectric strength measures the maximum voltage a grease can withstand without losing its insulating properties. The higher the dielectric strength, the better its quality as an insulator.
