Abstract
Insulation for high temperature applications includes glass fibers having an average diameter of between about 2.7 to about 3.8 microns. In one possible embodiment the insulation includes a polyacrylic acid binder. Such insulation has about 98 weight percent glass fibers and about 2 weight percent binder.
Claims23
An insulation for high temperature applications, comprising glass fibers having an average fiber diameter of between about 2.7 to about 3.8 microns, said insulation being substantially free of thermoplastic fibers and having an average density of between about 0.5 lb/ft3 and about 6.0 lb/ft3, wherein the thermal conductivity of said insulation at 500 degrees F. is less than the thermal conductivity of an insulation material having an average density substantially the same as said insulation and glass fibers with an average fiber diameter greater than said glass fibers of said insulation.
A high temperature appliance, comprising:
- a housing;
- a heating element carried by said housing;
- and
- an insulation element insulating at least a portion of said housing, said insulation element including glass fibers having an average fiber diameter of between about 2.7 and about 3.8 microns, said insulation element being substantially free of thermoplastic fibers and having an average density of between about 0.5 lb/ft3 and about 6.0 lb/ft3, wherein the thermal conductivity of said insulation element at 500 degrees F. is less than the thermal conductivity of an insulation material having an average density substantially the same as said insulation element and glass fibers with an average fiber diameter greater than said glass fibers of said insulation element.
An oven range, comprising:
- a housing;
- a heating element carried on said housing;
- and
- an insulation element insulating at least a portion of said housing, said insulation element including glass fibers having an average fiber diameter of between about 2.7 and about 3.8 microns, said insulation element being substantially free of thermoplastic fibers and having an average density of between about 0.5 lb/ft3 and about 6.0 lb/ft3, wherein the thermal conductivity of said insulation element at 500 degrees F. is less than the thermal conductivity of an insulation material having an average density substantially the same as said insulation element and glass fibers with an average fiber diameter greater than said glass fibers of said insulation element.
A water heater, comprising:
- an inner tank including a water inlet and a water outlet;
- an outer jacket received around said inner tank,
- a heating chamber adjacent said inner tank in said outer jacket;
- and
- an insulation element carried by one of said inner tank and said outer jacket, said insulation element comprising glass fibers having an average fiber diameter of between about 2.7 and about 3.8 microns, said insulation element being substantially free of thermoplastic fibers and having an average density of between about 0.5 lb/ft3 and about 6.0 lb/ft3, wherein the thermal conductivity of said insulation element at 500 degrees F. is less than the thermal conductivity of an insulation material having an average density substantially the same as said insulation element and glass fibers with an average fiber diameter greater than said glass fibers of said insulation element.
An insulation, comprising:
- glass fibers having an average fiber diameter of between about 2.7 and about 3.8 microns, wherein the insulation has an average density of between about 0.5 lb/ft3 and about 6.0 lb/ft3 and a thermal conductivity at 500 degrees F. less than the thermal conductivity of an insulation material having an average density substantially the same as the insulation and glass fibers with an average fiber diameter greater than the glass fibers of the insulation.
