Driven by the key materials application demonstration policy, the bio-based Eucommia gum industry accelerates development

Bio-based Eucommia Gum (EUG) is an excellent natural polymer material with dual properties of rubber and plastic produced from the Eucommia tree. It is the only natural high-quality rubber resource in the world with good development prospects besides hevea. In recent years, my country has continuously increased its strategic deployment in the field of bio-based Eucommia gum and promoted the research and development of extraction technology and application in the field of bio-based Eucommia gum, making my country’s bio-based Eucommia gum have made significant progress in industrial production and commercial application.

According to the “In-depth Market Research and Investment Strategy Suggestions Report on Bio-based Eucommia Gum Industry 2021-2025” released by the Industrial Research Center, On the one hand, my country’s first 100-ton industrial equipment was completed and put into operation at Hunan Xiangxi Laodie Biological Co., Ltd., which can produce bio-based Eucommia gum with a purity of greater than 94%. At the same time, my country’s fully enzymatic bio-based Eucommia gum trial production was successful, and A comprehensive extraction experimental device has been built in Tongren, Guizhou, and a second enzymatic extraction device has been built in Lishui, Zhejiang, and can produce products in batches.

On the other hand, my country has successfully developed Eucommia rubber aviation tires, new anti-puncture and bulletproof compositions, Eucommia rubber all-steel radial tires, bio-based reinforced plasticizer Eucommia resin, and high-strength Eucommia rubber modifications using bio-based Eucommia gum. Bio-based epoxy resin adhesives and other products; and bio-based Eucommia gum has been included in the draft of the “Guidance Catalog for the First Batch Application Demonstration of Key New Materials” (2021 Edition), so that it can be used in aerospace, marine engineering, and advanced rail transit Applications in other fields are accelerated.

From the perspective of the development prospects of bio-based Eucommia gum, first of all, Eucommia gum has the characteristics of water and moisture resistance, acid and alkali resistance, strong insulation, excellent shape memory, good thermoplasticity, wear resistance, fatigue resistance, strong tear resistance, etc., and has a wide range of uses. , there is broad room for development in aerospace, national defense, shipbuilding, medical, chemical and other fields, such as manufacturing green car tires, aviation tires, high-strength adhesives, shock-absorbing rubber products, self-healing functional elastomer materials, etc.

Secondly, our country is rich in existing Eucommia forest resources. The high-yielding Eucommia rubber varieties cultivated can yield up to 400-600kg of Eucommia rubber per hectare. Once the Eucommia planting area expands to more than 3 million hectares, the annual Eucommia rubber output can reach at least 120 tons, which can provide The bio-based Eucommia gum industry provides sufficient development resources. Furthermore, bio-based Eucommia gum is a new material that the country focuses on developing and has important strategic value. The support of national policies also brings benefits to the bio-based Eucommia gum industry.

Industrial analysts said that bio-based Eucommia gum can adapt to the application needs of different products and produce a variety of products with excellent comprehensive performance and long service life. Long-lasting, high-safety special rubber products are conducive to promoting the green and sustainable development of my country’s rubber industry. In the future, with the strong support and encouragement of national policies, the development speed of the bio-based Eucommia gum industry will gradually accelerate, and the number of industry-related enterprises will also gradually increase.
