Thermal Transitions Temperatures in Polymers
Thermal transitions temperatures are where the polymers change their state from one form to another just as H2O (not a polymer) is solid below 0 deg C, liquid between 0 and 100 deg C and gas above 100 deg C. In polymers there are three main types of such transitions temperatures.
The Glass Transition Temperatures - Tg
Below this temperature polymers are hard and brittle and above this the polymers are soft and flexible. In injection molded parts, post mold shrinkage will depend upon where the Tg is in relative to the room temperature and/or service temperature. If the Tg is above the room temperature and/or service temperature, post mold shrinkage is minimal. If the Tg is below room temperature and/or service temperature then post mold shrinkage will continue to take place till equilibrium is reached (think annealing).
During molding, if you set the mold tempertures too low - below the Tg, then you will not let the moecules reach equilibrium and the molded part will have a lot of in-built stress causing failures when a load is applied. The part can also change dimensions resulting in warpage and/or failures in a final assembly. In crstalline materials (see below) the Tc is always higher than the Tg and the mold temperatures should be set close to the TC.

Polymer Viscosity
The study of the viscosity and flow of polymers is called Rheology.
Viscoelasticity
When liquids are subjected to a force, the deformation is permanent. This property is called viscosity. Viscosity also is an indicator of the resistance to flow. Liquids are said to be viscous. When solids, example: metals, are subjected to a certain limited force the deformation is not permanent. When the force is released the solid recovers to its original shape. This property is called elasticity. The word ‘limited’ is used because excessive force causes permanent deformation, another topic of discussion. Plastics exhibit both a viscous component and an elastic component in their solid form and in their molten form. They are said to be viscoelastic and the behavior is called visoelasticity. This can be visualized with the spring and dash pot model.
Newtonian Fluid
A fluid whose viscosity is not influenced by the shear rate that is being applied to it. The viscosity remains constant as the shear changes. Shear rate in injection molding is synonymous to injection speed.
Non-Newtonian Fluid
A fluid whose viscosity changes with the change in the shear rate that is being applied to it. The viscosity does not remain constant as the shear changes.
All plastics are a combination of non – Newtonian and Newtonian behavior. At lower shear rates, the plastic is non-Newtonian but as the shear rate increases, the plastic tends to exhibit a Newtonian behavior. This happens because with increasing shear rate, the polymer molecules start to untangle from each other and start to align themselves in the direction of flow. After a certain shear rate most of the molecules are aligned in the direction of the flow and increasing the injection speed does not further affect the viscosity.
