A) Polyolefins
For Polyolefins, the following concentrations of LIBSTAT — CDA display a thorough antistatic effect:
- PP - 0.5%-1.0%
- LDPE - 0.2%-0.5%
- HDPE - 0.5%-1.0%
The concentration required in each case depends upon the method of processing and use. For instance, a smaller concentration is required for polyethylene sheeting than blown bottles.
The decisive factor for good effectiveness is the homogeneous distribution in the polymer, which can be achieved, for example, by simply mixing it with the pwdery polyolefin. The resulting mixture is then fed into the processing machines directly or after it has been compressed into granules. The method of first producing granules With a high ANTISTAT concentration and then bringing it up during manufacture to the required antistatic agent content with additive-free granules has also been proved successful.SURFACE RESISTIVITY HDPE sheets LDPE sheets Without antistat

LIBSTAT — CDA is recommended for use as an antistatic agent for polystyrene with 0.5% to 1.5%. Since it is also compatible with polystyrene in higher concentrations, the desired content of this antistatic agent can be adjusted with such granules by processing them together with additive-free polystyrene. It should pointed out, however, that these products have a certain lubricating effect and that this can cause excess lubrication in the extruder with higher concentrations.
