Description

Intro

GO YEN CHEMICAL INDUSTRIAL CO., LTD. (GYC GROUP) is a leading manufacturer of specialty chemicals in Asia. We devote ourselves to supplying products and solutions to our customers worldwide to satisfy and expand the market needs.

GY-FR-DOPO is a phosphorus-based halogen-free flame retardant with excellent thermal stability and water resistance. It is used in the flame retardant of epoxy resin by the front-end reaction method. It is suitable for flame retardant of various thermosetting resins. It can be widely used in flame retardant applications of PCB circuit boards, electrical laminates, plastics for electronic equipment, and copper lining laminates.

Good heat resistance and oxidation resistance, adding it in the granulation or blending stage can prevent the polymer from discoloration or coloring caused by heat.
