Application of talc masterbatch in polyethylene blown film and ABS resin
Application in polyethylene blow molding film
With ultrafine talc (1250 mesh, 2500 mesh) masterbatch filled with injection molding grade high-density polyethylene composites, in addition to the above performance has improved significantly, the tensile strength of this kind of composite material increases, add 10% increased to the maximum value, add 30% can still maintain the original strength, impact strength increased slightly.
For polyethylene blow molding film, filled with ultrafine talc masterbatch is better than other fillers, easy to mold, good processability. Moreover, this kind of film can make the oxygen transmission rate reduced by 80%, especially suitable for packaging oil-containing food, such as peanut rice, fava beans, etc., and keep out of oil for a long time, no deterioration; this kind of film can make the water vapor transmission rate reduced by 70%, and it has a very good moisture-proof, very suitable for the underground geotechnical moisture-proof cloth, and it is also suitable for packaging of food such as ham, meat sausage, cheese and so on.
Application in ABS resin
Ultrafine talc masterbatch, manufactured by special method, is added to plastics with good dispersion and uniformity.
ABS resin is an amorphous polymer, with polystyrene as good as the molding processability; it has good impact strength, good low temperature resistance, high tensile strength, good creep resistance, to withstand the 7Mpa load and the size of the unchanged, and therefore more than it is used for injection molding of a variety of instruments, televisions, recorders, cell phones, etc., of the shell, of course, in other areas, such as: textile equipment, electrical parts, automotive parts, aircraft parts, etc., the application is also very good. Of course, in other areas such as: textiles, electrical parts, automotive parts, aircraft parts, etc. are also very widely used. However, people are not satisfied with the existing performance of ABS, ABS modification of the research is being widely carried out, published information is not a few.
