“…Extremely important is also the balance between the filler density and specific surface and the viscosity of fused polymer. It depends on this balance whether silica will accumulate near the surface of the polymer under combustion or will it be immersed in the fused mass of polymer [25].…”

This paper presents the results of testing the flammability of silicone rubber composites containing fillers, such as cenospheres, cenospheres covered with iron, attapulgite, wollastonite, aluminum hydroxide and silica. In order to increase the insulating character of boundary layer, boron trioxide was incorporated into the composites of silicone rubber as a ceramization additive. The flammability of the composites was tested with the use of a cone calorimeter. The composition of the gaseous products of thermal decomposition was determined quantitatively and qualitatively in the system with intensive stirring in the fluidal bed, under isothermal conditions at temperatures T = 550, 650 and 750°C. All the test results show that the fillers used, especially with ceramization additives considerably reduce the fire hazard of silicone rubber composites containing these fillers.

“…The band near to 1750 cm -1 was assigned to the C-O stretching of the COOH and acetyl groups of hemicellulose of jute fabric 23 . It was prominent in control jute fabric but shifted to 1700 cm -1 and intensity decreases with increasing the concentration of SMSN on the fabric.…”

“…In the case of 8% SMSN treated samples there was 6 and 15% loss in tensile strength in warp and weft direction of the fabric, respectively. This change in tensile property may be due to mild adverse effect of alkali (of SMSN) on lignin and hemicelluloses of the jute fabric 23 .…”

Flame retardant and antimicrobial functionalities were imparted in jute textile using sodium metasilicate nonahydrate (SMSN), commonly known as "water glass". Sodium metasilicate nonahydrate (SMSN) was applied in jute fabric in different concentration by padding method followed by drying. Flame retardancy of the fabric was evaluated by Limiting Oxygen Index (LOI) and burning behaviour under vertical fl ammability tester including the char length. Burning rate was found to decrease by almost 10 times after an application of 2% SMSN compared to the control sample. Thermogravimetry (TG) and differential scanning calorimetry (DSC) analysis of both the control and treated jute fabrics were utilized to understand the mechanism of developed fl ame retardance in jute fabric. It was observed that the SMSN treated samples showed excellent antimicrobial property against both gram positive and gram negative bacteria. Antimicrobial properties of both the control and treated jute fabrics were also measured quantitatively.
