Why use cryogenic grinding: Some polymers require the use of cryogenic grinding in order to reduce the particle size. Given certain polymer properties, some materials do not behave in a way that is necessary to achieve desired particle size reduction results without being chilled. For example, crystalline materials would melt from the friction of the grinding process if they were not cooled ...
