ActivePlastics - Unsaturated-polyester resins (UP-R) - Part 1: Designation system
塑料 不饱和聚酯树脂（UP-R） 第1部分：命名系统
Application Summary AI generated
This standard establishes a designation system for unsaturated-polyester resins (UP-R) based on their key properties, such as reactivity, viscosity, and heat deflection temperature. It is applied by manufacturers and users in the plastics and composites industry to create uniform product codes for material selection, procurement, and quality control. The system ensures consistent identification of UP-R grades used in applications like fiber-reinforced plastics, coatings, and castings.
