For your case, you should contact the manufacturer of the plastic granulate material. The manufacturer will be able to add our entrainer additive BYK-P 4200 to their processes in order to reduce VOC or odor. The additive BYK-P 4200 only has an effect in combination with degassing, or even better, vacuum degassing, and is therefore not suitable for application in injection molding but must be applied in a previous processing stage. For polymers, the product is suitable for application in PP and ABS. We do not recommend using it in polyamides as the active ingredient is based on an aqueous emulsion and would destroy the polymer.
The inefficiency of the laser additive is most likely caused by an irregular distribution of the laser additive batch in the injection molding procedure. In this case, we recommend adjusting the process conditions in injection molding by increasing screw speed and dynamic pressure. If this does not solve your problem, you should discuss the matter with the manufacturer of your master batches. The manufacturer can achieve better distributive qualities of the laser additives in the master batch by adding dispersing additives such as BYK-P 4102. This should facilitate more even distribution of the laser additive during injection molding.
Such kind of product would have to be applicable to many different parts, and all of the physicals and thermal properties would come into play. HDT would be the biggest problem, because you will not be able to get it close to PP. We would recommend to use a polymeric processing additive such as BYK-P 4101. The additive brings down the surface tension of the filler or glass fibre to get it closer to the one of PE. The main benefit comes with the higher functionality of the BYK-P 4101 which provides better filler wetting and bonding into the polymer. By this, mechanical properties can be improved - especially the E modulus, impact strength and HDT.
