History and Properties of Rubber

BASF has significantly shaped the history of plastics and continues to shape its future BASF plastics help to increase energy efficiency and save resources in almost all industries Go to Performance Polymers Plastic Additives Our additives improve the processing and product properties of plastics and are therefore a problem solver for complex tasks in almost all areas of plastics processing Dispersion of reduced graphene oxide (RG-O) into natural rubber (NR) was found to dramatically enhance the mechanical electrical and thermal properties of NR However property improvements were strongly dependent upon the processing history and nanocomposite morphology Co-coagulating a stable RG-O suspension with NR latex afforded a weblike morphology consisting of platelet networks

History of Rubber Rubber was first discovered by the Indians living in Central and South America at around 1000 CE The native people of the Americas used latex from the rubber trees (which they called it the cahuchu tree) and learned how to make waterproof clothes and footwears 1 They also used the latex to make bouncing balls for ball games 1 In 1736 a French explorer named Charles Marie

Rubber definition is - one that rubs 1: an elastic substance that is obtained by coagulating the milky juice of any of various tropical plants (as of the genera Hevea and Ficus) is essentially a polymer of isoprene and is prepared as sheets and then dried — called also caoutchouc russia rubber

Natural rubber also called by other names of India rubber latex Amazonian rubber caucho or caoutchouc as initially produced consists of polymers of the organic compound isoprene with minor impurities of other organic compounds plus water Thailand and Indonesia are two of the leading rubber producers Types of polyisoprene that are used as natural rubbers are classified as elastomers

Rubber Mill In Others Applications Sudan 2020-6-1Phoenix dactylifera commonly known as date or date palm is a flowering plant species in the palm family Arecaceae cultivated for its edible sweet fruit Although its exact place of origin is uncertain because of long cultivation it probably originated from the Fertile Crescent region straddling between Egypt and Mesopotamia

Polymer concrete was introduced in the late 1950s and became well known in the 1970s for its use in repair thin overlays and floors and precast components Because of its properties like high compressive strength fast curing high specific strength and resistance to chemical attacks polymer concrete has found application in very specialized domains

What Are the Properties of Rubber?

28 01 2016In the early 1940s the US started researching and testing the properties of silicones to help with the war effort The first silicone product was a paste that protected electrical sparking equipment in airplanes Silicone Elastomer History Silicone rubbers are a modern category of elastomers and can be distinguished from organic polymers such as rubber latex and polyurethane among others

„Rubber" is a general term for all natural and synthetical caoutchoucs The rubber or elastomer consists of polymers which are connected through vulcanization and adopt elastic characteristics at room temperature There are a great number of these elastomers and they all can differ in their polymer structure polarity and surface properties This makes elastomers and rubber so difficult

This classification system tabulates the properties of vulcanized rubber materials (natural rubber reclaimed rubber synthetic rubbers alone or in combination) that are intended for but not limited to use in rubber products for automotive applications NOTE 1: The SAE Committe on Automotive Rubb
