General properties of rubber Rubbers are high molecular weight materials whose average molecular weight is not constant and varies depending on the operations they perform before and during processing. For example, the molecular weight of hydrocarbon rubber in natural freshly collected latex is higher. Of 1,000,000 However, when exposed to air, its molecular weight decreases rapidly. Thus, for example, butyl […]
Recycling in the rubber industry is almost as old as the rubber industry Charles Macintosh in 1820, just one year after starting to produce rubber raincoats, needed so much rubber that he could not import it. His research colleague Thomas Hancock found a new solution for him. Hankook built a machine that ground the rubber waste generated during the sprinkling […]
Some tips for polybutadiene rubber One of the most important aspects of PBR that is dangerous to human health is that polybutadiene polymeric materials should not be exposed to oxidants at all when they are in their packaging. It should be noted that PBR does not pose a direct risk to the environment. But if it is in pure contact […]

Metal glass is better or rubber Are metal glasses better or rubber? This question is asked by many people with glasses or those who intend to make the first glasses. The answer to this question is that the weight of the good features of the metal frame is greater. However, it is good to know the advantages and disadvantages of […]
What are the ingredients of tyre and why does it rot? In the construction of rubber, various chemical, natural and mineral ores are used, each of which plays a special role in the performance of the tire as well as in its production. In the construction of rubber, various chemical, natural and mineral materials are used, each of which plays […]
The NR (STR5L) rubber was purchased in block form from Chana Latex Co., Ltd. (Songkhla, Thailand), whereas CB (N-330, particles size 30 nm) and china clay (CC, C-400, mesh size 400) were acquired from GSP Products Co., Ltd. (Bangkok, Thailand). The CB and CC are generally considered as reinforcement and non-reinforcement fillers, respectively. Paraffinic oil (PO, grade A no.15), added […]
Impact force remains the primary cause of foot injury and general discomfort with regard to footwear. The footwear industry traditionally relies on modified elastomers (including natural rubber) whose properties can be physically adjusted by varying the constituents in the rubber formulations. This work aims to investigate the effect of filler/plasticizer fractions on shock attenuation of natural rubber soles. The statistical […]
History of Natural rubber in Malaysia Surely, the name of natural rubber is very familiar to your ears, you have heard its name from this and that many times, or you have even bought products of this material. Also called Amazon rubber, it is a polymer from the family of organic compounds of isoprene, which includes impurities from other organic […]
