Plastic additives Antistatic agent classification
Antistatic agent is a plastic additive. Because the volume resistivity of the polymer is generally as high as 1010 ~ 1020Ω /cm2, easy to accumulate static electricity and dangerous, and antistatic agents multi-system surfactants, can make the plastic surface close to water, ionic surfactants and conductive effect, so you can make electrostatic leakage in time. What kinds of plastic additives antistatic agent?
Non-ionic antistatic agent
Non-ionic antistatic agent has the advantages of good processing and thermal stability, mainly polyethylene glycol ester or ether, polyol fatty acid ester, fatty acid alkolamide, fatty amine ethoxy ether and other products.Cationic antistatic agent
Cationic antistatic agent mainly includes amine salt, quaternary ammonium salt, alkyl amino acid salt, among which quaternary ammonium salt is the most important.
Anionic antistatic agent
Anionic antistatic agent is not much, the common anionic antistatic agent in China is ABPS(sodium nonyl phenoxy propane sulfonate) and DPE(potassium p-nonyl diphenyl ether sulfonate). Atmer190(alkyl sulfate) developed by foreign U-niqema company [4] can be widely used in PS, pvc, PE, PC(polycarbonate), POM(polyformaldehyde resin), PA(polyamide), TPU(thermoplastic elastomer rubber) and other fields.
Mixed antistatic agent
Mixed antistatic agent refers to two or more types of surfactants combined with the use of new antistatic agent, which often has a better antistatic effect.
