The loss of adhesion between the propellant and insulator is one of the most important problems in solid propellant motors due to migration of plasticizer to interface of propellant and insulator. In this work, the polyurethane (PU) binder containing DOP plasticizer was used as a polymeric matrix and β-cyclodextrin (β-CD) was applied as inhibitor agent to prevent plasticizer migration from

flame retardants for fire proof plastics

Flame Retardants for Fire Proof Plastics

The use of fire retardant reduces the flame spread and so the rate at witch the smoke develops. Less smoke production gives an increase in the escape time available. 3. Minimize the Impact of Fire. Provide separation by tenant, occupancy, or maximum area. Maintain the structural integrity of property, Provide for continued operation of shared

The formation of dimer acid-derived plasticizer (DA-2n, Scheme 1) could be evidenced from the changes in NMR spectra, where cyclic dimer and trimer acids were chosen as representatives of DA to react with polyethylene glycol methyl ether. Figure 1b–e showed the appearance of new peaks at 4.2 ppm and 3.5–3.75 ppm were detected.
