my country, Europe and the United States and other countries have specially formulated laws and regulations to limit the content of various toxic substances. Masterbatch produced by regular manufacturers is not harmful. Masterbatch is composed of pigment and carrier with additive. Pigments are divided into inorganic pigments and organic pigments. Inorganic pigments mainly include: chromate series (chrome yellow, yellow, zinc yellow, etc.), oxide series (iron red, white, chromium oxide, etc.), sulfide series (brocade red, chromium oxide, etc.) yellow, etc.), silicate series (ultramarine, etc.), ferricyanide series (Hualan, etc.), metallic pigments (copper powder, aluminum powder, etc.), natural pigments (terracotta clay, red ten, etc.), other pigments (diamond blue).
Most inorganic pigments are insoluble in oil and water and has a certain particle size, so it is non toxic. Only those with Inorganic pigments containing heavy metal salt components such as lead and chromium have harmful intermediates. During processing and application, lead chromium pigments enter the human body mainly through the respiratory tract, followed by the digestive tract, but cannot pass through undamaged skin. Therefore, it is very necessary to wear door locks during the production process.
The main organic pigments include: phthalocyanine series, reducing dyes, condensed couplet macromolecules, couplets, acritones, lakes, chelate series, isimidone, acid dyes and salt based dyes, etc. Generally, organic pigments are less soluble, so most organic pigments are less toxic. On the other hand, because pigments are insoluble in water and difficult to dissolve in some common solvents, the hazards caused by organic pigments are mainly caused by processors and manufacturers.
The carriers of masterbatch are mainly: general plastics (PE, PP, PVC, PS, ABS, etc. 5 categories) and engineering plastics (PA, PC, POM, PPO, PET, PBT, PPS, PEK, PKKT, PES, PSF. PAR, etc.), these plastics themselves are less toxic or non toxic.
Some masterbatches also add Wei Caixiang copper and gold powder, pearlescent powder, silver powder and other effect pigments. Those produced by regular factories can pass SGS environmental testing standards. It is safe for clients to use.
