CRYSTAF-TREF

CRSTAF and TREF techniques are intended to measure the Chemical Composition Distribution in Polyolefins; CRYSTAF analyses it in the crystallization cycle and TREF in the dissolution cycle. 

The analysis of complex PP-PE combination has been shown to require both TREF and CRYSTAF to unequivocally characterize unknown samples due to the differences in the undercooling between both resins. Such a case is the analysis of samples containing both HDPE and Ethylene-Propylene copolymer (EP) for instance.
