A research has been carried out to develop natural rubber (NR) hybrid composites reinforced with marble sludge (MS)/Silica and MS/rice husk derived silica (RHS). The primary aim of this development is to scrutinize the cure characteristics, mechanical and swelling properties of such hybrid composite[r]
Tensile modulus, M100 and M300 and thermal stability improved with the addition of organoclay. In comparison with NR, ENR nanocomposites exhibited shorter scorch time and cure time, and higher maximum torque, which were related to the re[r]

The Government should create a national quality certification to ensure that only good quality rubber is exported from Vietnam. Vietnamese exporters will apply for this quality certification before export to increase the trust-worthiness of its goo[r]
This paper investigates the mechanical and thermal properties of styrene butadiene rubber (SBR) using dicumyl peroxide as curing agent. The results showed that the tear strength of SBR with 2 phr DCP as curing agent increased sharply from 31,7 N/mm to 73,2 N/mm compared to SBR cured with sulfur.
In this assessment, hybrid composites were prepared from the combination of industrial waste, as marble waste powder (MWP) with conventional fillers, carbon black (CB) as well as silica as reinforcing material, incorporated with natural rubber (NR). The properties studied were curing, mechanical and[r]
Finally, only Malaysia amongst natural rubber countries entered stage (5) of a late advanced economy, doing this in the mid-1980s (Table 1). Further rubber planting was not economic with very high wages (Table 3) and land prices, but estates contin[r]
Use stick matches to burn the string. The small ends of string left over from the knot acts as a fuse that permits the students to remove the match before the string burns through. Teachers may want to give student groups only a few matches at a tim[r]
The blends of epoxidized natural rubber/silica were prepared and characterized the properties which are necessary for the coating application. The epoxidized natural rubber was prepared by epoxidation of deproteinized natural rubber with fresh peracetic acid in latex stage.
