International Classification:

C08K 5/103
C08K 5/12

Abstract:

A process for preparing densified cellulose ester pellets with reduced clumping or taking comprises mixing a cellulose ester flake or powder and plasticizer to form a blend and directing the blend to a pellet mill. The densified pellets retain the mechanical properties of the cellulose ester flake or powder. An additive may be introduced to the blend or to the pellet mill to reduce downstream compounding steps. The pellets may be stored without clumping, thus reducing processing steps and increasing yield.

Abstract:

Systems and methods for forming fiber reinforced polymer tapes are disclosed. A method may include, for example, traversing a polymer impregnated roving through a system comprising an inlet and an outlet, applying a consolidation pressure within the system to the polymer impregnated roving, and applying a smoothing pressure within the system to the polymer impregnated roving. The method may further include adjusting a temperature of the polymer impregnated roving with a heat transfer device between the inlet and the outlet, the heat transfer device having a temperature different from a temperature of the polymer impregnated roving at the inlet.
