Are usually low-melting solids or high-boiling organic liquids which, when added to hard plastics, impart flexibility. They have varying degrees of softening action and solvating ability resulting from a reduction of intermolecular forces in the polymer....

The characteristics of being easy to mold without rupturing or developing flaws due to movement of the polymer during gelation....

A lubricant used to coat a mold cavity to prevent adhesion of the molded piece when removed....

Rate of extrusion of molten resin through a die of specified length and diameter. The conditions of the test (e.g. temperature and load) should be given. Frequently, however, the manufacturer’s data lists only the value, not the condition as well....

A concentration of a substance (an additive, pigment, filler, etc.) in a base polymer....

Internal lubricants, without affecting the fusion properties of a compound, promotes resin flow. External lubricants promote release from metals which aids in the smooth flow of melt over die surfaces. ...

The process that involves an integrated system for proportioning, mixing, and dispensing two component liquid resin formulations and directly injecting the resultant mix into a mold which is clamped under pressure....

The difference between the size of the part and the size of the mold cavity. Values given are often the average of a range....
