Burning or heat-sensitive materials

Cause:

Resins such as PVC HDPE PS LDPE PP and others might burn during processing.

For example, PVC is an extremely sensitive resin, so it is usually processed at a heat of less than 190 degrees, using a screw with a low L/D (usually 20) in order to reduce the heat delay time to a minimum, while achieving a satisfactory process within a short amount of time.

Solution:

We recommend processing PVC and similar sensitive materials in a dual screw system, in order to get a low process/delay ratio that will prevent its burning.

Prevent stopping the machine during the PVC processing. If forced to stop, start by removing it and cleaning with a suitable RAMCLEAN® product (RAMCLEAN® 500/600).

Determining the correct RAMCLEAN® solution will be performed by completing the TEG questionnaire or through a Chat conversation with the RAMCLEAN® experts.
