Q1: What types of polymers is Atmer 122 compatible with?
A: Atmer 122 is widely used in thermoplastic polymers including polyolefins (e.g., PP and PE), ABS, PS, and engineering plastics such as PC and PA. Its compatibility stems from its non-ionic surfactant structure and balanced hydrophilic-lipophilic properties.
Q2: How does Atmer 122 reduce static charge in plastic articles?
A: Atmer 122 functions by migrating to the polymer surface during processing or storage, where its hydrophilic head groups attract atmospheric moisture to form a conductive layer. This facilitates dissipation of electrostatic charges without compromising bulk insulation properties.
Q3: Is Atmer 122 suitable for applications requiring low extractables or food-contact compliance?
A: Atmer 122 is formulated for low volatility and minimal migration under typical processing conditions. While it is not pre-approved for all food-contact regulations, it has been successfully incorporated into food packaging and medical device applications where regulatory assessment is conducted on a case-by-case basis by the end-user.
Q4: What is the typical dosage range for effective antistatic performance?
A: Effective performance is typically achieved at low concentrations, generally ranging from 0.1% to 2% by weight relative to the base polymer. Optimal dosage depends on resin type, processing conditions, required surface resistivity, and environmental humidity.
Q5: Can Atmer 122 be added during compounding, or is post-addition also viable?
A: Atmer 122 is most commonly incorporated during melt compounding for uniform dispersion. However, it can also be applied via masterbatch dilution or dry-blend techniques prior to extrusion or injection molding—provided adequate mixing energy is applied to ensure homogeneity.
