Liquid rubber generally refers to a class of oligomers with a relative molecular weight of about 2000 10000, a viscous liquid at room temperature, and a chemical cross-linking reaction can occur further under certain conditions. There are many varieties of liquid rubber, which is widely used, and is mainly used as a modifier in the rubber and adhesive industry, playing the role of plasticizing and viscosity. The liquid rubber used in the rubber products and adhesive industry is mainly liquid polybutadiene rubber, liquid nitrile butadiene rubber and liquid isoprene rubber. 
Liquid polybutadiene rubber has the advantages of very low glass transition temperature, excellent hydrolysis resistance and electrical insulation, and generally has non-functional structure and modified structure, and common modification methods such as maleic anhydride grafting and hydroxyl termination. Polybutadiene liquid rubber with different chemical structures is widely used in structural adhesives, electronics, and automotive sealants.

Development opportunities for liquid polybutadiene industry
Technological advancement: With the continuous advancement of technology, the production efficiency and quality of liquid polybutadiene are also improving, which further drives the growth of its market demand.
National Strategic Security Reserve: Terminal hydroxyl polybutadiene (butadiene hydroxyl rubber) is a very important liquid rubber variety, due to its special chemical structure, butadiene hydroxyl rubber has excellent physical and chemical properties, can maintain stability and reliability in extreme environments, plays a key role in solid propellants, cladding, lining, space vehicle escape towers and other applications, is widely used in aerospace and defense fields. With the development of the national military industry and the improvement of the demand for strategic reserves, the continuous installation of new equipment models, and the rapid development of commercial aerospace, the demand for butadiene hydroxyl rubber from downstream customers will rise rapidly.
Downstream applications: Liquid polybutadiene is widely used in the formulation of paint and coating intermediates. Liquid polybutadiene is used in the formulation of coatings to reduce the total solvent content of the final coating formulation. Growth in the paints and coatings industry is expected to boost demand for liquid polybutadiene.
Due to the hydrophobic nature of liquid polybutadiene, the demand for liquid polybutadiene in the electronics industry is also on the rise. Due to its superior properties with high wear resistance, the compound is also ideal for tire manufacturing. Apart from tire manufacturing, it is also used in the manufacture of several products such as bumpers, rim pads, tire sidewalls, and bead fillers, which will drive the market growth.

Development risks of liquid polybutadiene industry
*Expensive: At present, the market of high-end liquid rubber remains high, compared to the traditional rubber and elastomer market, liquid rubber only occupies a small part.
Technical requirements, high production costs: the production process and preparation equipment of liquid polybutadiene are high, coupled with its significant economies of scale, resulting in a large investment in R&D funds in the early stage of the enterprise. Although high-end products are much more expensive than ordinary products, in terms of yield, it is not a proportional increase.
The global environment is unstable: high-end liquid rubber is frequent, and if there is no relatively safe environment, then the difficulty and cost will increase greatly.
Substitutes appear: With the progress of science and technology, more and more substitutes appear, if the product performance of substitutes meets the requirements of the current product, and the best is more favorable, then the current product will be hindered.
