Humidity-Resistant Paper Insulation Sheets
- Temperature Range: 0° to 265° F
- Heat Flow Rate: See Table
- Density: See Table
- Color: Off-White
- Specifications Met: UL 94 V-0, UL 94 5VA
Often used in high-humidity applications for its low moisture absorption, this flexible paper insulation is made of inorganic materials. It’s typically used in appliances and electrical devices. Insulation meets UL 94 V-0 and UL 94 5VA for flame resistance.
Thermally Stable Composite Paper Insulation Sheets
- Max. Temperature: 1100° F
- Heat Flow Rate: 0.22 Btu @ 75° F
- Density: 8.7 lbs./cu. ft.
- Color: White
- Specifications Met: UL 94 V-0
Made of flexible composite paper, these sheets won't shrink or lose shape in the high temperatures of air furnaces and hot water tanks.
Electrically Insulating Hard Fiber
- Color: Gray
- Max. Temperature: 235° F
- Tensile Strength: See Table
- Impact Strength: 2.5 ft.-lbs./in. (Good)
- Hardness: Rockwell R70 (Hard)
- For Use Outdoors: No
- Specifications Met: MIL-I-695, UL 94 HB
Widely known as fishpaper and vulcanized fiber, these thin sheets offer better electrical insulation than standard hard fiber sheets. They are constructed from lightweight cotton fabric that's been chemically treated to make it hard and dense.
