* Flow Characteristics of KEPITAL

 

1. Basic principle

    Melt Index, Melt Flow Length and Viscosity are measurements of the flow characteristics of plastics.

    This article will clarify the flow characteristics of KEPITAL standard grades.

 

2. Flow characteristics

 (1) Melt Index (MI)

      1) KEPITAL Standard Grades are distinguished according to viscosity, and Melt Index is

            measured in accordance with ISO 1133.

      2) F10-03H has the lowest Melt Index among the standard grades, and we can conclude that

            F10-03H has high viscosity. (We call it the high-viscosity grade.)

      3) The number associated with the name of the KEPITAL grade(FXX) increases according to

             Melt Index. [F20-03(medium-viscosity grade) represents our standard grade.]

 (2) Melt Flow Length by injection pressure

      1) Melt Flow Length is one way to measure flow characteristics of resin and measures the length

            of melt resin pushed out by pure injection pressure without holding pressure at a fixed speed.

      2) As you can see in the above table, Melt Flow Length increases as injection pressure increases

            but the rate of change is different.

      3) As the viscosity of a grade lowers, the Melt Flow Length increases through injection pressure.
