Crystallization of polymers is a process associated with partial alignment of their molecular chains. These chains fold together and form ordered regions called lamellae, which compose larger spheroidal structures named spherulites. Polymers can crystallize upon cooling from melting, mechanical stretching or solvent evaporation. Crystallization affects optical, mechanical, thermal and chemical properties of the polymer. The degree of crystallinity is estimated by different analy… WebMay 30, 2024 · 3.1 Thermal Properties. Bovine anhydrous milk fat (AMF), which is the fat isolated from butter, has a broad melting range from −40 to +40 °C (Fig. 9.2 ). AMF must be warmed at least to +40 °C to ensure complete melting of TAGs and is not completely solid until it reaches a temperature below −40 °C.
