The development history of rubber and plastics industry and the transformation of silicone products.silicone baby pacifier clip wholesale

　　Rubber and plastics have been discovered as early as the eleventh century, but they have been neglected. In 1819, Scottish chemist Mackintosh discovered that rubber can be dissolved by coal tar. Since then, people have begun to dissolve rubber with coal tar, turpentine, etc. Manufacture of tarps. Since then, the world's first rubber factory was established in GLASGOW, England in 1820. In order to facilitate the processing of rubber products, in 1826 Hancock (Hancock) invented a method of mechanically making natural rubber plastic. In 1839, American Goodyear invented the vulcanization method of rubber, which solved the problem of raw rubber becoming sticky and brittle, and made the rubber have high elasticity and toughness. Only then did the rubber really enter the industrial practical stage. Therefore, natural rubber has become an important industrial raw material for silicone products, and the demand for rubber has also risen sharply.

　　As early as the 11th century, the people of South America used rubber balls for games and sacrifices. In 1493, when the Italian navigator Columbus made his second voyage to the Americas, he saw the Indians playing with a black ball in his hand. Since then, Spain and Portugal have brought rubber knowledge to Europe one after another in the process of conquering Mexico and South America.

　　In the 18th century, France continuously sent scientific expeditions to South America. In 1736, the French scientist Charles de Condamine participated in the South American scientific expedition, and brought back some rubber products and related information about rubber trees from Peru to France, and published "Travel Notes on the Inland of South America". The book detailed the origin of rubber trees, the method of collecting latex, and the process of using rubber to make pots and shoes, which attracted people's attention.

　　In 1768, the Frenchman P. J. Macquer discovered that rubber could be softened with solvents to make medical supplies and hoses. In 1828, the Englishman C. Mackintosh used latex to make rainproof cloth, but the product was sticky in hot weather, brittle in cold weather and poor in quality.

　　During the second industrial revolution in Western countries in the 1880s, the British doctor Dunlop invented the pneumatic tire in 1888. In 1876, the Englishman H. A. Wickham transported the seeds and seedlings of rubber trees from Brazil to Kew Garden in the Royal Botanical Garden in London for propagation, and then transported the cultivated rubber seedlings to Ceylon (now Sri Lanka), Malaya, Planting in Indonesia and other places has been successful. Now silicone rubber is also widely used in automotive rubber parts.

　　In 1887, Malaysia, Sri Lanka, and Indonesia expanded and established rubber plantations. H. N. Ridley, director of the Singapore Botanical Garden, invented the continuous rubber tapping method of repeated cutting on the original incision without damaging the cambium of rubber trees, and corrected the origin of rubber trees. The old method of cutting down trees to get rubber and thus hurting the tree and unable to produce rubber for a long time enables rubber trees to tap continuously for decades.

　　With the development of silicone products, in the 19th century, silica gel has been applied to life and the medical industry has gradually opened up in the domestic market. In recent years, the sales of silica gel products have achieved remarkable results in life medical products. With the leap-forward growth of consumption, the silicone rubber industry has begun to transform from high-performance special rubber to synthetic rubber, becoming one of the largest types of rubber. It is reported that from the perspective of consumption of rubber, natural rubber accounts for 41.8%, and styrene-butadiene rubber and butadiene rubber together account for 28.4%. Therefore, as silicone rubber products replace other types of rubber in some non-tire segments, their consumption will increase exponentially, and the market space will be further opened.

　　In this regard, industry insiders also agree with the above point of view. It is estimated that by 2017, silicone rubber products will account for 10% to 15% of the total domestic rubber consumption, that is, the consumption of silicone rubber is expected to reach 1 million to 1.5 million tons, and by 2020, silicone rubber will account for the total rubber consumption. The proportion of silicone rubber is expected to reach 20% to 33%, that is, the consumption of silicone rubber is expected to reach 3 million to 5 million tons. In other words, the development potential and long-term development of the silicone rubber industry are very attractive, and its rapid development will also have a profound impact on the upstream and downstream industries. In fact, the linkage effect of the upstream and downstream industries of the silicone rubber industry has begun to gradually emerge.

　　According to statistics, if the proportion of silicone rubber in my country's rubber product consumption is increased from the current 6.5% to 33% by 2020, then the overall domestic self-sufficiency rate of my country's rubber can be increased from the current about 50% to more than 80%, which will greatly alleviate the The tight rubber supply situation reduces the production cost of the rubber processing industry. It can be seen that the development of the silicone rubber industry is not only a single development of a single industry, but involves the common development of multiple industries, which has far-reaching significance for enhancing the profitability of the rubber processing industry and improving the quality level of rubber products.
