How much is a ton of natural rubber?
Hevea brasiliensis originated in the Amazon river basin and has been planted in more than 40 countries and regions. Natural rubber is an elastic solid made of natural latex collected from rubber trees through a series of processing procedures.
Thailand, Malaysia, Indonesia and some other countries supply natural rubber to the international market. However, the United States and Japan are big users of natural rubber and are totally dependent on imports. China is also the second largest importer of natural rubber in the world, which has a direct impact on international rubber prices.
Among them, the price of natural rubber in Malaysia, Indonesia, Thailand and Southeast Asian countries is about 7000~ 12000 yuan per ton. The price of rubber in Japan is about 20000 ~ 35000 a ton.
The price of China NR 20 15 is about 1200 yuan ton, and 20 16350 yuan a ton. The price of first-class natural rubber in Yunnan entered the "40,000 era" for the first time, with an average price of 40,097 yuan/ton, of which the most expensive gutta-percha is about 43,000 yuan/ton.
What are the advantages of rubber?
1. High and low temperature resistance: the creep and relaxation changes of products at high and low temperatures are one of the conditions to distinguish the quality. Rubber products are solid elastic materials, which will not change physically at room temperature. However, when the temperature exceeds 100℃, the products will creep except some metal rubber products, which will affect the use. Therefore, in the high-temperature or low-temperature working environment, the correct selection of rubber products can maintain its reasonable service life and work efficiently.
2. Safety requirements: According to food requirements, when selecting rubber products, we should pay attention to whether the products need to touch food or directly enter the mouth, such as pacifiers and milk bottles. In terms of medical requirements, due to the need to seal highly toxic chemicals, the safety requirements are higher. For volatile liquefied gas, it is required to have high acid and alkali resistance and flame retardancy. Such as medical rubber products and medicine containers. In the field of petrochemical industry, it is also necessary to meet the requirements of fire prevention and high temperature resistance of rubber products. For conveying equipment, not only high temperature resistance is required, but also high working pressure is required.
3. Economic benefit: Now many rubber products are made of all kinds of rubber, with low cost and meeting the requirements. However, when selecting rubber products, we should consider whether it will cause material losses, economic consequences and other losses caused by damage. Therefore, in addition to selecting products according to demand, we should also consider their cost performance comprehensively.
In addition to the above advantages, natural rubber also has excellent resilience, insulation, water resistance, plasticity and other characteristics, and after processing, it also has the advantages of oil resistance, acid resistance, alkali resistance and wear resistance, so natural rubber is widely used. Natural rubber is indispensable to high-tech products such as rain boots and warm water bags used in daily life, airplanes, tanks and even artificial earth satellites used in national defense.
