Flame retardant performance of a carbon source containing
The combination of gas‐phase and condensed‐phase action will contribute to high quality flame retardant. A novel 9,10‐dihydro‐9‐oxa‐10‐phosphaphenanthrene‐10‐oxide (DOPO)‐based flame retardant (DOPO‐DOPC), which contains carbon source was synthesized in favor of conducting the effect of gas‐phase as well as promoting the char formation in condensed‐phase.
Flame retardant Plamtar-DOPO-HQ - Polymate Additives
Plamtar-DOPO-HQ is a new phosphine halogen-free Flame retardant, for high quality epoxy resin such as PCB, to replace TBBA, or adhesive for semiconductor, PCB, LED and so on. Intermediate for synthesis of reactive Flame retardant. Packing. 25kg/bag.
Novel DOPO-based flame retardants in high-performance carbon
Since the ester group in the ground body of the two flame retardants is highly susceptible to hydrolysis (Fig. 5 b), this is the first group of the flame retardants to decompose. A carbonylic acid functionality with the DOPO moiety is formed at the end of the chain, and a hydroxy group with the pentaerythritol or isocyanurate rest.

Intermediate for synthesis of reactive flame retardant. DOPO-ITA(DOPO-DDP) 63562-33-4: DDP is a new type of flame retardant. It can be used as a copolymerization combination.
- Why is Dopo a flame retardant?
- Thus 9,10-dihydro-9-oxa-10-phosphaphenanthrene-10-oxide (DOPO) has become one of the most important flame retardants in this field, now used in several modifications as a reactive or additive compound , , , , , , , . DOPO shows excellent flame-retarding properties in epoxy-based materials.
- Which flame retardant reduces PHRR and the?
- Both flame retardants reduced the PHRR and THE in the order RTM6-CF > RTM6-CF + DOPP = RTM6-CF + DOPI, indicating a flame-retarding action in the composites as well. The residue of RTM6 + DOPP and RTM6 + DOPI was increased in comparison to that of RTM6. This led to the shoulder in the HRR curve of RTM6 + DOPP and RTM6 + DOPI.
- Are phosphorus flame retardants halogen-free?
- Flame retardants containing phosphorus seem to offer a promising halogen-free way to render epoxy resins and their composites flame retardant in the future , .
- Do flame retardants decompose?
- Since the ester group in the ground body of the two flame retardants is highly susceptible to hydrolysis ( Fig. 5 b), this is the first group of the flame retardants to decompose. A carbonylic acid functionality with the DOPO moiety is formed at the end of the chain, and a hydroxy group with the pentaerythritol or isocyanurate rest.
- Does flame retardant improve Loi of rtm6?
- The LOI of RTM6 with flame retardant was improved by around 12% for RTM + DOPP and by 9% for RTM6 + DOPI. The flame-retarded composites showed an amelioration of the LOI of +12% for RTM6-CF + DOPP and + 14% for RTM6-CF + DOPI in comparison to RTM6-CF.
- Why do flame retardants have a higher flame inhibition than non-flame-retarded material?
- The lower the THE/ML in comparison to the non-flame-retarded material, the stronger the flame inhibition of the flame retardant. Furthermore flame inhibition goes along with incomplete combustion, which increases the smoke and the CO release in the gas phase.
