A review of the scientific technical literature in the field of modern research on silicone rubber compositions with high temperature resistance, including those with fire-resistant properties, is presented. The polymer bases and heat-stabilizing and flame-retardant additives used in the developments, as well as methods for preparing rubber mixes and rubbers are shown. Features of compounding materials with a combination of heat resistance and fire-resistance are noted. The relevance of research for the needs of aviation equipment is shown.

Abstract A series of experiments on the flammability of EPDM formulations which contained a minimum amount (30 phr) of aromatic organic flame retardant (DBDO) revealed that increasing the crosslink density increased the flame resistance. This was especially true when the formulations were cured by a combination of DCP, TAIC, and HVA-2. The best result was obtained in a formulation which was cured by DCP/TAIC/HVA-2 at 2.5/1.0/0.5 phr, respectively. This material had excellent physical properties that would be well suited for use in the wire and cable industry. It was also found that good dispersion of individual ingredients was needed to obtain optimum flame resistance.

Abstract This study examined effect of inclusion of expanded graphite (Exp-G) on morphology, thermal, mechanical and flame retardant properties of PS, nitro-substituted polystyrene (N-PS) and amino-functional polystyrene (A-PS). FESEM showed exfoliated sheet morphology due to intercalation of N-PS and A-PS in expanded galleries. Tensile strength of A-PS materials (31.5-56.9 MPa) was higher than PS and N-PS. 10 % weight loss of A-PS nanocomposites (482-518 °C) was higher relative to pristine polymer and other nanocomposites. Cone calorimetry results revealed that there was lowering in PHHR of A-PS nanocomposites with 0.5 wt.% filler (428 kW/m2), while PS nanocomposites showed PHHR of 443 kW/m2.

Ammonium polyphosphate (APP) has six crystalline forms, in which form II is commercially applied as flame retardant in engineering plastics such as PP and ABS, form V is extensively studied recently. In preparation of APP, the reaction atmosphere is significant to controllably obtain a certain crystalline forms. In this paper, the effect of wet ammonia is investigated. The results show that low concentration of wet ammonia is suitable for preparation of form II, while dry ammonia is suitable for preparation of form V. The results are informative for controllable preparation of APP in industrial production.
