began selling his materials for laboratory testing and as a super-fine filter media. With some US federal grant money and a new business plan focused on the plastic additives market, he was able to locate angel investors willing to move the company to the next level and create InPore Technologies.
Market-driven innovation Moves to reduce the amount of halogenated FR used in plastics are opening the doors to the global US$4.2 billion market for FR materials, with resin producers, compounders and OEMs evaluating new alternative formulations. This period of innovation creates an excellent environment for the introduction of a new inorganic platform material like Silapore particles. The phenomenal porosity and the resultant high surface

area are the most notable properties of Silapore particles. A specific surface area of 1,200 m2
of particles has the same area as five tennis courts. As produced, Silapore particles have low levels of
attraction to one another so that the resultant powder is made up of agglomerates in the 10 micron – 300 micron size range. Handling the powder is similar to other fine particulate mineral fillers requiring basic personal protection and dust control equipment typically found in processing fine additives. When used as a flame retardant, the particles act as
char formers in the polymer matrix, separating the polymer fuel source from oxygen and the hot gases of combustion. It is likely that they will deliver the best results in combination with other intumescent and gas- phase flame retardants.
