Using Polyvel’s CR5 or CR5P peroxide masterbatches is a cost efficient way to increase the melt flow of polypropylene. These masterbatches will shorten injection molding cycle times resulting in cost savings.

The following chart shows how lowering the processing temperature during molding reduces the cycle time from 38 to 26 seconds. Productivity increased 50% from 95 to 140 parts per hour.

Aside from exceptional dispersion of peroxide throughout a polypropylene processing environment, Polyvel peroxide masterbatches offer the following major benefits:

1)      Safety in handling

2)      Safety in storage

3)      Easy uniform addition of peroxide to the compound or process

4)      Improved stability of the peroxide (increased shelf life)

5)      A very cost effective way to increase the melt flow rate of polypropylene

6)      Available at 5%, 10%, and 20% loadings, or tailored to your application
