2 2 3 Masterbatch CERETAN micronized waxes for Colour Masterbatch Today all typical processes of the plastics industry use Masterbatches. They are to be found in processes of extrusion, injection moulding and blow moulding. Master batches consist of a polymer, pigments and waxes. Compared to traditionally used wax powders CERETAN waxes offer various advantages. This brochure helps to find the best suitable products and enables you to optimize your Masterbatch as well. High performance dispersing agents Reduction of wax usage Increased colour strength by 5 % 15 % Reduction of pigment costs Lower filter pressure Reduced clogging of filters Less mixing time necessary Less extrusions necessary Comparison of the particle size Wax powder (500 µm) Pigment (1 µm) Micronized waxes The spherical shape guarantees: Very good dispersibility Constant and consistant colour output No film tearing Reduced clogging of filters and centrifuges CERETAN micronized waxes (e.g. CERETAN MX 9820, D 50 < 8 µm) Pigment (1 µm) Level of addition The dosage level of our waxes depends on various factors, such as your individual Masterbatch formulation, the kind of application, the used pigments and plastics. According to your requirements, a dosage of 0,5 % 15 % of CERETAN waxes is advisable.

3 Reduction in wax usage MÜNZING a leading manufacturer of spray micronized waxes produces up to 100 times smaller particles than traditional powder waxes. Offering identical chemical properties CERETAN waxes are more effective due to their particle size and shape. Lower filter pressure By using CERETAN micronized waxes the flow capability of the processed material will be improved. Therefore, clogging of filters is reduced and mounting of the product can be eliminated (test results on page 4). Dispersing agent The excellent wetting properties of CERETAN waxes provide an improved dispersion of the components, especially in SPC (Single Pigment Concentrate). Increased colour strength by 5 15 % Improved pigment wetting properties of CERETAN waxes will result in an increased colour output. Reduction in wax usage The much finer particle size reduces the amount of waxes used. The expected results are achieved faster by incorporating CERETAN waxes instead of non micronized waxes. The amount of foreign substances (such as agglome rates) in the formulation and sedimentation in the processing tubes is reduced or even eliminated. Masterbatch production process Polymer 2..

5 CERETAN waxes for colour Masterbatch Micronized Products CERETAN MA 7050 This micronized amide wax (EBS) shows very good performances with all pigment and plastic applications, especially PS and ABS. CERETAN ME 0980 This micronized PE wax can be used for the production of SPC (Single Pigment Concentrate), as well as for mixed colours. Even in very high concentrated colour batches CERETAN ME 0980 is the best suitable dispersing agent. It can be used universally in many kinds of plastics and for the dispersion of all kinds of pigments. Generally speaking, PE waxes have excellent release properties. CERETAN ME 1430 Spray micronized PE wax for the production of SPC (Single Pigment Concentrate), as well as mixed colours. Even in very high concentrated colour batches CERETAN ME 1430 works as best suitable dispersing agent. It can be used universally in many kinds of plastics and for the dispersion of all kinds of pigments. Generally speaking PE waxes have excellent release properties. Due to its non polarity, it is not recommended in PVC. CERETAN MM 8120/ CERETAN MM 8220 Spray micronized Montan E and OP waxes, which are recommended for all kinds of inorganic and organic pigments. They can be used in more or less the whole range of plastics. CERETAN MO 4615 Spray micronized oxidized PE wax for PE batches and PVC applications. Suitable for all kinds of pigments. CERETAN MP 2150 This micronized Polypropylene is used for all polyolefin applications and some technical plastics. You can apply it for all kinds of pigments. CERETAN MP 2150 works more effective in your processes. Due to the fine particle size, the dispersibility is much better compared to the usage of a non micronized wax. CERETAN MV 0330 Compared to other products CERETAN MV 0330 shows the best results in reducing filter pressure. Ethylene- Vinyl- Acetate is suitable for all kinds of plastics, especially for Carbon Black and pigments that are difficult to disperse, but also for all other pigments. Due to the micro nized particles your processes will work more effectively. CERETAN MX 9820 This spray micronized blend of PE and FT can be used in all kinds of applications. Because of the combination of different chemistries it provides excellent dispersion and lubrication properties. Non-Micronized Products CERETAN A 70 If you require an amide wax (EBS) which is suitable for all pigment and plastic applications CERETAN A 70 is the right choice. We recommend it especially for PS and ABS. CERETAN A 71 This Erucamide wax has excellent flow properties in the extrusion process. It is recommended to be used for all kinds of plastics except for PET and ABS.
