FEATURES AND BENEFITS of UL 94 Flame Classifications UL 94-5VA Surface Burn; Burning stops within 60 seconds, test specimens MAY NOT have a burn-through (no hole). This is the highest (most flame retardant) UL94 rating.
The role of silicon-containing species as possible synergists with APP and similar flame retardants is further demonstrated by the observation that silicotungistic acid (SiO 2 ·12WO 3 ·26H 2 O) may be used as a catalyst or synergist in polypropylene (PP) flame-retarded by the intumescent flame-retardants.
Flame retardant applications for polypropylene are proportionately much less important than for other resins such as styrenics and engineering thermoplastics. This is due mainly to the difficulty in reaching the high standards of flame retardancy required in the electronics and building industries with polypropylene compounds (PP).
A novel flame retardant with the high flame-retardant effect, namely 1-(4-hydroxyphenyl)-3-(10-oxido-5H-phenophosphazine-10-yl) pyrrolidine-2,5-dione (DPPA-HPM), was synthesized to solve the problem. The nuclear magnetic resonance and high-resolution electrospray ionization mass spectrometry verified the successful synthesis of DPPA-HPM.

The term flame retardants subsumes a diverse group of chemicals which are added to manufactured materials, such as plastics and textiles, and surface finishes and coatings. Flame retardants are activated by the presence of an ignition source and are intended to prevent or slow the further development of ignition by a variety of different physical and chemical methods. They may be added as a copolymer during the polymerisation process, or later added to the polymer …
