Explore our foundational range of liquid rubber compounds, metallic alloy powders, and specialty chemical materials engineered to meet stringent global application standards.
Yanxatech System Industries Limited (hereinafter referred to as YANXA) stands as a highly progressive and technologically integrated supplier in the specialty chemical and mechanical material landscape in China. Originally founded in 2008 as a highly focused small business unit, YANXA has been propelled by a steady commitment to internationalizing advanced Chinese specialty materials. Over the last decade and a half, our enterprise has matured into a trusted partner, bridging scientific research institutes, state-of-the-art production facilities, and global industrial procurement hubs.
Our core operating philosophy is built upon the pillars of safety, quality assurance, and dynamic operational efficiency. We recognize that industrial procurement, particularly in the domain of specialty elastomers and liquid rubber formulations, demands more than off-the-shelf catalog fulfillment. It demands customized viscosity profiles, precise active functional terminal group percentages, and unmatched batch-to-batch structural uniformity. Cooperating closely with the nation’s leading national research institutes and advanced factories, YANXA supplies high-grade liquid rubbers, specialized nitrate formulations, and atomized metallic alloy powders designed to withstand critical industrial stress limits.
Liquid rubbers serve as structural modifiers, thermal barriers, and performance enhancers. Below we analyze the chemistry, polymerization pathways, and application advantages of our key liquid elastomers.
CTBN represents a liquid copolymer of butadiene and acrylonitrile characterized by active carboxyl functional groups located at the polymer chain terminals. When blended with epoxy resins, it undergoes controlled phase separation during curing, generating microscopic elastomeric domains (sea-island structure) that absorb impact energy and restrict crack propagation without compromising heat distortion temperatures.
HTBS is a hydroxyl-terminated random copolymer synthesized from butadiene and styrene monomers. Featuring hydroxyl terminals, it exhibits high reactivity toward polyisocyanates, allowing for the formation of polyurethane-elastomer hybrids. Styrene incorporation elevates the polymer backbone's rigidity, leading to superior shear strength, thermal stability, and low-temperature flexibility.
MLPB is formed by grafting polar maleic anhydride groups onto a polybutadiene backbone. This structure combines hydrophobic polybutadiene flexibility with highly reactive anhydride sites. It is extensively applied as a coupling agent for glass fiber/rubber composites, a compatibilizer in polymer blending, and an adhesion promoter for structural metal coatings.
HTBN is an advanced liquid copolymer that utilizes hydroxyl end groups to achieve reactive crosslinking. Primarily applied in extreme engineering scenarios, HTBN offers a balance of nitrile polar resistance against oil, fuel, and chemical solvents, combined with the flexible backbone of polybutadiene. It is a critical matrix binder in complex polyurethane coatings, solid rocket propellant formulations, and potting compounds designed for high-vibration automotive or aerospace environments.

For specialized defense, pyrotechnic, aerospace, and electronics applications, we maintain active supply lines for high-grade alloy powders and gas materials:
How YANXA combines digital manufacturing, ISO controls, and logistical advantages to build a highly stable B2B supply link.
Liquid rubber synthesis requires extremely high control over polymerization parameters. A slight shift in reaction temperature can affect the molecular weight distribution, terminal group conversion rates, and the viscosity of the final polymer, which can impact the curing process for clients.
Our partner manufacturing units utilize digital control systems (DCS) to monitor the entire polymerization process in real-time. By implementing automated monomer feeding systems and continuous feedback loops, we ensure that every batch of CTBN or HTPB conforms to narrow tolerance specifications. Our laboratories utilize gas chromatography (GC), gel permeation chromatography (GPC), and Fourier-transform infrared spectroscopy (FTIR) to verify functional group values before packaging and shipping.
Quality and reliability form the foundation of our business. Our manufacturing facilities operate under certified ISO 9001 quality management structures. Under these guidelines, we enforce a strict quality control loop:
Our specialty elastomeric compounds and material solutions are engineered to address performance demands in modern industrial sectors.
In aerospace applications, HTBN and HTPB serve as high-performance elastomeric binders in solid propellant compositions, offering structural integrity and low-temperature elasticity. Additionally, our atomized aluminum-magnesium powders are utilized as high-energy combustion additives in advanced defense systems.
Modern vehicles rely on structural adhesives modified with CTBN to handle mechanical impacts, vibration, and thermal expansion cycles. These modifiers enhance peel strength and shatter resistance in hem-flange bonding, structural pillars, and crash-box structures without increasing vehicle weight.
For high-frequency printed circuit boards (PCBs) and sensitive electrical components, HTBS-modified polyurethanes provide moisture protection, vibration damping, and electrical insulation. Their low dielectric constant and low moisture absorption maintain signal integrity in high-frequency applications.
As polymer engineering evolves, YANXA is aligning its R&D efforts to address key technical trends shape the future of liquid rubber chemistry.
Traditional liquid rubbers are derived from petroleum-based butadiene and nitrile feedstocks. To support global sustainability targets, we are researching bio-derived butadiene monomers produced from agricultural ethanol. The resulting elastomers will offer equivalent technical performance with a lower carbon footprint.
We are investigating pre-dispersed nano-silica and graphene in CTBN and HTBN matrices. These pre-dispersions allow customers to incorporate nano-reinforcements directly into epoxy formulations without requiring high-shear dispersion equipment, improving thermal conductivity, flame retardancy, and tensile modulus.
Handling highly viscous liquid rubbers like CTBN can be challenging in solvent-free systems. We are developing low-viscosity, multi-functional liquid rubbers that act as reactive diluents, reducing formulation viscosity without compromising the crosslinking density or mechanical properties of the cured thermoset resin.
For space and vacuum applications, we are refining our purification processes to eliminate volatile low-molecular-weight oligomers. The resulting low-outgassing liquid rubbers will help prevent sensor contamination in space exploration and satellite systems.
