What is Natural rubber

Malaysian natural rubber is produced from plants and is classified as a chemical compound in the group of polymers that are made up of large, identical molecules. Malaysian natural Rubber is also known by other names such as natural rubber, Malaysian rubber, latex, Amazon Natural  rubber or rubber. It is composed of isoprene organic polymers with minor impurities and other organic compounds plus water. Thailand and Indonesia are the top two producers of natural rubber in the world. Polyisoprene types used as natural rubbers are classified as elastomers. Some of these polymers are naturally occurring and others are produced in laboratories and factories so natural rubber and synthetic rubber can be produced. More information in this regard will be provided in the following article in Panorama Global Trade Sdn Bhd. Malaysian natural rubber is one of the most important polymers in human society. Today, the first introduction to rubber begins with the seventh grade science course for teens. Natural rubber is an essential raw material used to create more than 40,000 products. It is used in medical devices, surgical gloves, aircraft and car tires, pacifiers, clothing, toys, and more. The world price of Malaysian natural rubber and synthetic rubber is a function of the daily price of oil in the world. Natural rubber is made from whitish milky liquid that contains proteins, starches, alkaloids, etc., which is made by many plants. About 20,000 species of plants produce latex, but only 2,500 species have rubber in their latex. The biological function of natural rubber for plants is unclear. However, it has been shown that it can help heal plants after they have been damaged by covering wounds and stopping the loss of fluid within the plant. This compound also prevents harmful bacteria and viruses from entering the plant. Natural rubber is composed of long isoprene polymer chains that are loosely bonded together. When detached, the chains reconnect on their own, giving the tire elasticity. Unlike synthetic rubbers made by petrochemical companies, natural rubbers are made from the latex sap of trees, and they supply up to 99% of the latex needed by the world.  Malaysia is the fifth largest manufacturer and exporter of natural rubber in the world. Malaysia is also the leader in the production and export of rubber products such as rubber gloves, pneumatic tires, inner tubes, catheters, condoms, footwear, rubber bands and rubber sheets. Rubber production in Malaysia is set to double by 2020, provided the Malaysian government’s ambitious development plans for the industry come to fruition.  In 2011 the country produced nearly 1 million tones of rubber, according to statistics from the Malaysian Rubber Board (MRB). Under the Economic Transformation Program (ETP), production is expected to reach 2 million tones per annum by the end of the decade, boosting the sector’s contribution to gross national income (GNI) to RM52.9bn ($17.06bn), up from RM18.5bn ($5.97bn) in 2020.  Panorama Global Trade Sdn Bhd is our subsidiary for the distribution and export of Standard Malaysian Rubber blocks. Our company also have  Standard Malaysian Rubber 20 (SMR20) license from Malaysian government under Panorama Global Trade Sdn Bhd (License number W/01/16896) . Panorama Global Trade have the capability to export Standard Malaysian rubber 20 to our clients throughout the world. 

Rubber features

Malaysian natural rubber has flexibility and strength, as well as impurities and vulnerability to environmental conditions and hydrocarbons. Compared to other tires, natural rubber is one of the most flexible types and is resistant to water and some chemicals. It is also resistant to cutting, tearing, abrasion, fatigue and abrasion and has a working range between -58 to 212 degrees Fahrenheit. In addition, it has high tensile strength and easily adheres to other materials. However, natural rubber is not as effective at resisting heat, light and ozone as other rubbers such as neoprene. It also varies depending on the type of tree from which it is produced and also contains natural impurities. While natural rubber is resistant to water and some chemicals, it is still vulnerable to oil and non-polar solvents. 

How Natural rubber is made

Natural rubber must first be collected from a rubber-producing tree, then processed with chemicals and heat to be used in production. In this process, the tree is cut down and its sap is poured into a container. One-third of the latex at this stage is rubber, which is held in a colloidal suspension, and the other third is water. To treat latex into rubber, latex is mixed with formic acid to coagulate the rubber, then washed and compressed into a block or sheet, and then smoked. Then, through machining, other changes are made in the rubber to make it more efficient, then it is mixed with chemicals to improve its properties. Eventually, it is extruded into desired shapes and then vulcanized, making it more durable and resilient. Vulcanization involves heating the rubber with some sulfur in a pressure cooker at about 320 degrees Fahrenheit, although it can be steamed, microwaved, or passed through a fluidized bed or molten metal salts to be boiled. Vulcanization binds polyisoprene molecular chains together to create physical and chemical resistance and to eliminate crude rubber adhesion. Although synthetic rubber was invented in the 1930s, natural rubber, or rubber, is still widely used, making up just under half of the market.

Applications of natural rubber

Standard Malaysian rubber is a revolutionary change in grading presentation of Malaysian rubber natural rubber in the struggle with synthetic rubber hence the Standard Malaysian rubber  scheme has crucial to to play in the process of securing the status quo which , Malaysian natural rubber had been enjoying before the establishment of the synthetic industry. Standard Malaysian rubber (SMR) is fast becoming a household word both among Malaysian natural rubber (NR) producers and consumers. It was first introduced as the result of a long-felt need to improve the system of quality grading and presentation of Malaysian NR. Natural rubber is used in applications that require high resistance to abrasion and heat. Thanks to its strength and compressibility, natural rubber is used in engineering applications such as anti-vibration bases, actuator couplings, springs, bearings, rubber bands and adhesives. But most of them – 50% natural rubber – are used in high-performance tires for racing cars, buses and airplanes because of their strength and heat resistance. These compounds are also used in hoses, auto parts, floor mats and battery boxes. However, thanks to the adhesive nature of natural rubber, it is even found in rubber cement and soil stabilizers used on new roads. Even raw rubber is sometimes used as an adhesive and as part of a shoe sole. In addition, about 10% of latex harvested from trees is simply reduced to 60% rubber solution for the production of products such as latex gloves or as a cover.  Formally launched by the minister for commerce and industry in 1965. The Standard Malaysian rubber  Scheme has, over the years, establishment full buyers confidence in the technical grading system adopted and consumers have unreservedly accepted the improvement’s in the presentation of SMR. Four existing grades (SMR CV70, Standard Malaysian rubber LV, Standard Malaysian rubber WF and Standard Malaysian rubber  50) with little market demand have been deleted , whilst 2 new constant viscosity field grades have been incorporated as Standard Malaysian rubber  10CV and Standard Malaysian rubber  20CV, other grades have been incorporated as SMR 10 CV and Standard Malaysian rubber  20 CV other grades (Standard Malaysian rubber CV 60, SMR CV 50 , Standard Malaysian rubber L , Standard Malaysian rubber 5 , Standard Malaysian rubber GP, Standard Malaysian rubber  10 , and Standard Malaysian rubber 20) have been retained because of their sustained or stable uptake consumer
