Product description:Condutive Polyethylene Terephthalate (PET)
Electrically Conductive Masterbatch For PET
ESD Protection
Separate feeding technology is used to add conductive carbon black (CB) to the polyethylene terephthalate (PET)/polyethylene (PE) blend, and it is melted, blended and extruded through a Buss reciprocating pulsating extruder. Through granulation, a fiber-grade PET/PE/CB conductive masterbatch with better comprehensive properties was prepared. The study found that using a PET/PE incompatible blend instead of PET as the matrix resin of the conductive masterbatch can achieve a lower CB dosage. Obtain better conductive properties; when the mass fraction of CB is 15%, the volume resistivity of the masterbatch first decreases and then increases as the amount of PET increases. When the mass ratio of PET to PE is 60:40, The masterbatch has the lowest volume resistivity.
The conductive concentrate is a PET conductive masterbatch polymerized using a specific process. The masterbatch is added to the slices of the corresponding PET grades. The resistance can reach 10E7-9Ω·cm, which can effectively achieve the anti-static or conductive effect. Compared with similar products on the market, this masterbatch has many advantages such as low resistance value, stable resistance value, less addition amount, and lower cost.
PET conductive masterbatch is made of CB or CNT as the main material and high-medium melt flow Index PET resin as the base material. It is made of pellets through twin-screw extrusion and complies with EU environmental standards (ROHS). This product can meet the application fields of different production processes such as injection molding grade, wire drawing grade, extrusion grade, blown film grade, and blow molding grade.

Introduction of conductive masterbatch manufacturing process
1.Put special conductive carbon black and carrier into a high mixer at a predetermined ratio and mix with additives such as dispersant, antioxidants and grafting agents. Then use twin-screw extrusion. This is called a primary conductive masterbatch and can be used in conventional pipes. The added amount is about 20%. The concentration of carbon black in the conductive masterbatch of ordinary carbon black is not very high, especially when nano grade carbon black is mixed with resin. Achieving large additions is difficult. If you add too much, you can easily see an open flame and cause the resin to break down.
2.The primary masterbatch is dried, and after installing the filter, perform secondary extrusion and granulation. During this process, it can be used as a packaged conductor by making it into a special/universal masterbatch or diluting it to the desired concentration. As a conductive masterbatch, sufficient concentration and its conductive resistance value are required. Since the masterbatch is the final product, be aware of the filtration thresholds of the various conductive carbon blacks used in the resin.
