UpcomingPlastics—Determination of residual styrene monomer in polystyrene (PS), impact-resistant polystyrene (PS-I), acrylonitrile-butadiene-styrene (ABS) and styrene-acrylonitrile (SAN) resin—Gas chromatography
塑料 聚苯乙烯（PS）、抗冲击聚苯乙烯（PS-I）、丙烯腈-丁二烯-苯乙烯（ABS）及苯乙烯-丙烯腈（SAN）树脂中残留苯乙烯单体含量的测定 气相色谱法
Application Summary AI generated
This standard specifies a gas chromatography method for quantifying residual styrene monomer in polystyrene (PS), impact-resistant polystyrene (PS-I), ABS, and SAN resins. It is applied in quality control and regulatory compliance testing within the plastics manufacturing industry, particularly for food contact materials, toys, and consumer goods where styrene migration limits must be verified. The method ensures product safety by measuring unreacted monomer levels that could pose health risks during end-use.
