THERMAL, SWELLING AND MORPHOLOGICAL PROPERTIES OF PALE CREPE/SBR BLEND VULCANIZATE

Arum Yuniari

Abstract


Information thermal properties were needed in the manufacture rubber goods, because these properties are associated with the designation. Mixing between the two polymers to obtain superior properties of the individual polymers are currently being pursued to development. The purpose of this research was to study the effect of sulfur on the properties of pale crepe/SBR blend vulcanizate. Vulcanizate were prepared in varied ratio of pale crepe/SBR 80/20; 70/30; 60/40 and 50/50 phr and varied amount of sulfur 1 and 1,5 phr (per hundred resin). Blends of pale crepe and styrene butadiene rubber (SBR) are prepare using two-roll mixing. The effect of amount sulfur on thermal, swelling and morphological properties of the blends were studied. The amount of sulfur shows a significant effect on swelling properties. The thermal analyzes with TGA/DTA of the rubber vulcanizate indicated decomposition temperature at 520 ºC. Morphological of the rubber vulcanizate with sulphur 1,5 phr produced a homogenous mixture.

 

Keywords: pale crepe, SBR, thermal, swelling, morphological.
