A flame retardant sugar-derived molecule, a process for forming a flame retardant sugar-derived molecule, and an article of manufacture comprising a flame retardant sugar-derived molecule are disclosed. The flame retardant sugar-derived molecule can be synthesized from arabitol, xylitol, arabic acid, or xylonic acid obtained from a bio-based source, and can have at least one phosphoryl or phosphonyl moiety. The process for forming the flame retardant sugar-derived molecule can include reacting arabitol, xylitol, arabic acid, or xylonic acid and a flame retardant phosphorus-based molecule to form the flame retardant sugar-derived molecule.

A flame-retardant aconitic acid-derived small molecule, a process for forming a flame-retardant polymer, and an article of manufacture comprising a material that contains a flame-retardant aconitic acid-derived small molecule are disclosed. The flame-retardant aconitic acid-derived small molecule can be synthesized from aconitic acid obtained from a bio-based source, and can have at least one phosphoryl or phosphonyl moiety with phenyl, allyl, or thioether substituents. The process for forming the flame-retardant polymer can include reacting an aconitic acid derivative with a flame-retardant phosphorus-based molecule to form a flame-retardant aconitic acid-derived small molecule, and combining the flame-retardant aconitic acid-derived small molecule with a polymer. The material in the article of manufacture can be a resin, adhesive, polymer, etc.

The present invention relates to a non-halogen flame retardant resin composition. More particularly, the present invention provides a non-halogen flame retardant resin composition capable of simultaneously exhibiting superior flame retardancy, whiteness, and gloss by addressing problems of a flame retardant resin such as difficulties in realizing V-1 grade or higher flame retardancy when a non-halogen flame retardant is used and poor colorability due to low gloss and whiteness.

A polyisocyanurate foam insulation product includes polyisocyanurate foam produced from reacting an isocyanate and a polyol blend having a functionality of at least 2.2. The isocyanate and the polyol blend are reacted so that the polyisocyanurate foam has an isocyanate index equivalent with or greater than 300. The polyisocyanurate foam includes a fire retardant and includes between 0.02 and 0.45 weight percent of a zinc salt compound. The foam insulation board exhibits a flame spread of no greater than 25 and a smoke index of no greater than 50 when exposed to flame conditions in accordance with an ASTM E-84 test.
