Professional R&D and excellent quality plasticizer chemicals

EDA-DOPO, the environmentally friendly flame retardant developed at Empa, is going into serial production. The newly developed, particularly economic and ecological synthesis method, which also simplifies the production of other DOPO derivatives, is a crucial part of this success story.

The flame retardant epoxy resins include DOPO–DGEBA and ODOPB–DGEBA are two kinds of typical DOPO series resins which have been widely researched till now. For comparing the flame retardant behaviors of HAP–DOPO, DOPO and ODOPB on themosets, we prepared DOPO–DGEBA/DDS (sample F6) and ODOPB–DGEBA/DDS (sample F7) thermosets containing 1

Two types of DOPO (9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide)-based halogen-free flame retardants, ODOPB (2-(6-oxid-6H-dibenzo[c,e][1,2]oxaphosphorin-6-yl)-1,4-benzenediol) and DOPO-PhOH (1,10-bis(4-hydroxyphenyl)-methylene-bispheny-1-oxophosphine oxide), were synthesized and incorporated into polyisocyanurate–polyurethane foams to investigate their effects on the thermal stability
