摘要： Disclosed are foam compositions and processes to form mixed tannin-phenolic foams. The foams comprises a continuous polymeric phase defining a plurality of cells, wherein the continuous polymeric phase comprises a mixed-resin derived from a phenol, a tannin, and a first monomer, and wherein the plurality of cells comprises a plurality of open-cells and a plurality of closed-cells with an open-cell content measured according to ASTM D6226-5, of less than 50%. The foam composition also comprises a discontinuous phase disposed in at least a portion of the plurality of closed-cells, the discontinuous phase comprising one or more blowing agents.

摘要： A nonwoven web of unmodified or cyanoethylated nanocellulose was found to have greater strength than kraft paper after immersion in oil at high temperature, making it useful as an insulation material for transformers. A mixture of nanocellulose and polymetaphenylene isophthalamide has further improved properties for use as an insulating material.
