Rubber thread, an indispensable material for numerous applications, has been in use for over two centuries since its initial discovery and continuous production. Because of its remarkable flexibility and waterproof qualities, it is highly sought-after and easy to get, and it has become a necessary part of our everyday life.
Commonly referred to as elastic thread, rubber thread is a fine filament, crafted from rubber. There are two primary types of rubber: synthetic, derived entirely from oil through extensive chemical processes, and natural, extracted from the sap of the white-colored rubber tree, predominantly found in tropical climates. Rubber threads, mostly derived from natural sources, are used to make a wide range of products, including sports equipment like gym mats, balloons, wheels, rubber straps, and medical devices including surgical gloves and catheters. Its unique properties set it apart from synthetic rubbers, as it cannot be replicated.
The sap of rubber trees contains a milky-colored substance called latex, which is crucial in the production process of making rubber threads. Latex is commonly found in certain types of rubber trees, such as Ficus Elastica, which predominantly thrive in the Southeast Asia region. Together with other Southeast Asian nations, Omnimax, a well-known rubber thread manufacturer under PT. Cilatexindo Graha Alam in Indonesia, is one of the main suppliers, accounting for roughly three quarters of the world market for natural rubber.
Hevea brasiliensis or Pará rubber tree found in South America, particularly the Amazon forest in Brazil, is another latex-yielding plant. Both types of trees produce highly elastic raw rubber materials capable of enduring repeated stretches without breaking. Beyond exceptional flexibility, their efficacy as electrical insulators and resistance to corrosive substances enhance their versatility, making them popular choices for textiles, medical, and industrial applications. The unique molecular structure, known as a polymer chain, further contributes to their ability to revert to the original shape after undergoing multiple stretches.
In conclusion, the enduring significance of rubber thread in various applications is rooted in the remarkable properties of natural rubber derived from trees like Ficus elastica and Hevea brasiliensis. Their unparalleled elasticity, electrical insulation capabilities, and resistance to corrosive elements have solidified rubber thread as a crucial material for centuries, meeting diverse needs across industries.
