A method of making fibrous mats, webs, and/or blankets containing one or more low volatile de-dusting agents, and the fibrous products so produced, the method eliminating or substantially reducing condensation of volatiles in the drying oven, oven recirculating ducts and oven exhaust ducts and eliminating or substantially reducing oven and duct fires while producing fibrous products having effective dust suppression properties.

[Object] Provided are inorganic fibers or inorganic flakes having excellent neutron shielding properties.

[Solution] When a formulation including: a base component containing SiO.sub.2 and Al.sub.2O.sub.3 as main components (provided that the mass ratio occupied by the sum total of SiO.sub.2 and Al.sub.2O.sub.3 in the base component is 0.60 or more); and a neutron shielding component composed of at least one of gadolinium, gadolinium oxide, samarium, samarium oxide, cadmium, or cadmium oxide, are blended at the proportions of 50 to 90 parts by mass of the base component and 10 to 50 parts by mass of the neutron shielding component and melted, satisfactory amorphous inorganic fibers and inorganic flakes were obtained.

A loosefill insulation product is disclosed. The loosefill insulation product can include a plurality of insulation fibers and a coating on the plurality of insulation fibers. The coating can include a silicone, and an oil. The loosefill insulation product leaches less than detectable amounts of alkali or alkaline-earth metals based on the total weight of the loosefill insulation product when analyzed with SEM/EDS analysis. The loosefill insulation product has an improved corrosion inhibition effect on aging, and passes the corrosion test as per ASTM C764.

A method for dedusting a fibrous insulation product using an epoxidized vegetable oil, such as epoxidized soybean oil, having a iodine value less than 10 cg I.sub.2 per gram and an oxidation exotherm by pressure differential scanning calorimeter of less than 500 joules/gram at an oven temperature of 130 C. and an oxygen inlet pressure of 500 PSIG. The fibrous insulation product typically is made with a binder composition that is applied to mineral fibers in addition to the epoxidized vegetable oil prior to the binder composition being cured.
