A New Energetic Mixed Formal Plasticizer, Using Diformal as
This new plasticizer is expected to be cheaper than the existing mixed formal because only one compound of starting material, DNP-OH, is required, DNB-OH will not be used for this process, and the yield of formalization reaction was increased from 75 % to more than 90%. Furthermore, this plasticizer does not crystallize at-20.

BDNPF/A is a useful energetic plasticizer, but mixed formal, which consists of BDNPF, DNPBF, and BDNBF, is anticipated to be better than BDNPF/A in chemically, thermally and economically. Last year, we successfully synthesized and characterized the mixed formal that has minimum contents of diformal.

- Is bdnpef a good plasticizer?
- Compared to commercial nitro plasticizers, BDNPEF synthesized in this study showed good plasticization efficiency with a decrease in glass transition temperature ( Tg) and viscosity of uncured glycidyl azide polymer (GAP) blends, as well as substantial ability to plasticize the GAP-based polyurethanes (PUs).
- Is bdnpef an effective energetic plasticizer for energetic binders?
- The physical and thermal properties of BDNPEF itself were measured. In addition, the plasticization effect of BDNPEF on energetic GAP-based PU binders was investigated to evaluate its potential as an effective energetic plasticizer for energetic binders. 2. Experimental 2.1. Materials
- What are plasticizers used for?
- Plasticizers are additives used widely in the polymer industry , , , . Generally, plasticizers are used to reduce the modulus, tensile strength, hardness, density, melt viscosity, Tg, electrostatic chargeability and volume resistivity of a polymer, while at the same time increase the flexibility, elongation at break and toughness.
