Abstract
A thermal insulation product which effectively blocks the transmission of infrared radiation through the product is provided and includes, in combination, an insulating material and a chiral polymer adapted to block the passage of infrared radiation through the insulating material.
Claims9
A thermal insulation product comprising:
- an insulating fiber batt containing fibers selected from the group consisting of mineral fibers, synthetic polymer fibers, cellulose fibers, and mixtures thereof;
- and
- an infrared radiation blocking material consisting essentially of a chiral polymer selected from polyphosphazenes, wherein the chiral polymer has a chain length of from about 0.7 to about 300 microns and has from about 10,000 to about 500,000 molecules in a backbone chain, and wherein the thermal insulation product is capable of scattering, reflecting or absorbing infrared radiation with a wave number of 200 to 4500 and a wavelength of from about 0.7 to about 300 microns.
A thermal insulation product comprising:
- an insulating fiber batt containing fibers selected from the group consisting of mineral fibers, synthetic polymer fibers, cellulose fibers, and mixtures thereof;
- and
- an infrared radiation blocking material consisting essentially of poly(bis(methoxyethoxy)ethoxyphosphazene).
