Natural Rubber: Grades and Selection webinar announced

Bangkok, Thailand – Knowhow Webinars is presenting Natural Rubber: Grades and Selection on July 28; Time: 11 a.m. CST, led by Dr. Brendan Rodgers.
Natural rubber is among the most important elastomers used in the manufacturing of products such as tires and conveyor belts. The polymer imparts many unique properties such as high tensile strength, tear strength and resilience. This review will discuss natural rubber, beginning with its biosynthesis, through to production, classification and fundamental properties. Natural rubber is obtained by tapping the side of the tree, Hevae brasiliensis. It is then processed and classified according to the quality and form under which it is shipped. Natural rubber is the preferred polymer in tire applications were high tear strength, tensile strength and low hysteretic properties are required. It is used in wire coat or skim compounds, the shoulder wedge and bead filler, and in tread compounds for winter passenger, medium truck and off-the-road tires. In many tire applications, natural rubber is blended with other elastomers to achieve a required balance of properties. Sidewalls are typically blends of natural rubber and polybutadiene. Innerliner compounds, which are discussed in depth, can contain natural rubber in low amounts when blended with either chlorobutyl or bromobutyl rubber to achieve a balance of high impermeability, good adhesion, excellent flex-fatigue resistance and good durability. The review will also cover natural rubber grader selection by application, interchangeability of grades and quality.
