ActivePlastics polyester resin - Determination of partial acid value and total acid value
塑料 聚酯树脂 部分酸值和总酸值的测定
Application Summary AI generated
This standard specifies the titration method for determining the partial and total acid values of polyester resins used in plastics. It is applied in quality control and formulation testing within the rubber and plastics industry, particularly for unsaturated polyester resins in composite materials, coatings, and adhesives. The method helps assess resin reactivity, curing behavior, and storage stability by measuring free and combined acid content.
