In a large, statistically significant, one-of-a-kind study, researchers at Los Alamos National Laboratory have confirmed that the explosive called PETN (Pentaerythritol tetranitrate), stabilized with a polysaccharide coating, is resistant to changes in particle shape, size, and structure that can degrade detonator performance over time. The benefits of polysaccharide coating have long been known and studied by Los Alamos energetic material scientists.
