Flame retardant compositions that are halogen-free or substantially halogen-free are disclosed. In certain examples, the compositions comprise a halogen-free or substantially halogen-free epoxide and one or more phosphorated compounds. In some examples, the phosphorated compound comprises an average particle size less than 10 microns. In other examples, the phosphorated compound provides a surface area of 78.5 &#x3bc;mto about 1965 &#x3bc;m. Prepregs, laminates, molded articles and printed circuit boards using the compositions are also disclosed.

Flame retardant compositions with a phosphorated compound

An improved aerogel and a process for production of the same. The improved aerogel which has a significantly reduced dust (e.g., aerogel fines) and static charge, as compared with conventional aerogel products. The aerogel also has a 'sticky' or 'tacky' nature which can be used to attract any available dust, fines and/or particulate matter and also restrict flowability of aerogel granules, for example, out of a breached container and thereby minimize loss of the aerogel product through any breached opening.

Flame retardant compositions that are halogen-free or substantially halogen-free are disclosed. In certain examples, the compositions comprise a polyphenylene ether, a halogen-free or substantially halogen-free polyepoxide, and one or more phosphorated compounds. Prepregs, laminates, molded articles and printed circuit boards using the compositions are also disclosed.
