Abstract
A process and product thereof for densifying guayule shrubs by compression and forming a densified pellet. The densified pellet substantially maintains its molecular weight during storage over a period of weeks without the aid of any inert gas blanket or the like.
Claims17
A process for prolonged storage of guayule by densification, comprising the steps of:
- shear free compressing ground guayule material, and forming in a cavity of densified brittle pellet having about a 50% to about a 325% increase in density so that said pellet retains at least 70% of its molecular weight during a two week period of time.
A densified guayule pellet comprising:
- the pellet, said pellet being brittle and having a density of from about 3 pounds to about 8.5 pounds per gallon, said pellet having approximately a 70% weight average molecular weight retention based upon the original molecular weight over a two-week period of time.
