Applications
As printed circuit board PCB epoxy flame retardant resin：
Since GY-FR-DOP has more rigid structure and belong to the characteristics of the phosphorus system, thus produced phosphorus-containing epoxy resin has :
- better flame retardance
- higher glass transition temperature
- Excellent thermal stability
- compare to traditional halogen-containing epoxy resin, it produces less toxic smoke
- applied to the printed circuit board (PCB) and electronic sheet with excellent fire effects
flame retardant thermoplastic polyester:
good garbon ratio and flame retardant efficiency for PET. can give excellent thermal stability and flame resistance, produce less toxic fumes & corrosive gases, GY-FR-DOP ‘s phosphorus-containing groups located at molecular side chains into thermal cracking .
anti-discoloration agent for ABS resin:
- GY-FR-DOP for ABS resin in the molding process can provide a great anti-fade resistance.
- Dosage of GY-FR-DOP for ABS resin in added is 0.1 ~ 1 phr , GYC Technology recommends 0.1 ~ 0.5 phr, within the scope of this addition is better.
- GY-FR-DOP and in combination with a hindered phenolic stabilizer such as BHT, sulfur compounds such as adenosine triphosphate DLTDP or the like, can provide an excellent effect.
As polypropylene heat stabilizer:
When add GY-FR-DOP 0.1~ 0.2 phr to injection molding grade polypropylene, it can prevent thermal discoloration effectively.
Other flame retardant applications:
- GY-FR-DOP’s reaction product and itaconic acid can be used as a reactive polymer fire retardant; GY-FR-DOP’s reaction product with bis (hydroxymethyl) – benzoguanamine polymers can be used as add-fire agent.
Dosage
Recommended dosage: 12-15%
The dosage level is to be regarded as a general guideline that can be adjusted according to the type of material and the expected effect.
Packing
