Description

The Best Offer Of Halogen-Free Reactive Flame Retardants From Us!

Halogen-containing flame retardants are highly beneficial and effective for flame retardancy, but they are not environmentally friendly as they release toxic and corrosive gases into the atmosphere. So, we are here with the best solution for you, providing you Dopo Flame Retardant, the best suitable alternatives because of their excellent flame retardancy.

How our Dopo Flame Retardant is different?

For epoxy resins, we offer the best Halogen-free reactive flame retardants, which are highly beneficial for the use of PCB and semiconductor encapsulation. Also, they are highly suitable for yellow resistant additive for the synthesis process for PS, ABS, PP, Epoxy resin, and many other chemicals and intermediate flame retardant.

As novel phosphorus-containing flame retardants, DOPO and its derivatives exhibit flame extinguishing behavior and excellent thermal stability concerning other flame retardants.

Moreover, our product is a phosphorous organic whose chemical combination is are linked to resin

matrix and shows much better performance than other phosphate esters in flame retarding because of the P-C bond.

Furthermore, we have test-proved products and ensure to provide you Dopo Flame Retardant with less smoke density and no formation of corrosive gases for molders or extruders. Also, it is highly suitable for high TG applications for resin and thermoplastic
