China’s Most Advanced Facilities: 

Equipped with the nation's most advanced liquid helium and helium filling production lines.

Certified under the ISO 9001:2008 Quality Management System.

Utilizes internationally recognized "filling island-style" production lines.

Gaseous helium from a reliable gases supply is ideal for semiconductor lithography, fiber-drawing, leak detection, carrier gas in GC, and balloon inflation. Liquid helium, sourced from a dedicated gases supply chain, is dedicated to MRI magnet cryo-cooling, superconducting magnet maintenance, and low-temperature physics research.

Ethylene, a colorless, slightly sweet-smelling hydrocarbon (C₂H₄), is the backbone of modern petrochemical industries. As the simplest alkene with a reactive carbon-carbon double bond, it exhibits high flammability (explosive range: 2.7–36% in air) and serves as a critical building block for synthetic chemistry. Used as feedstock for LLDPE/HDPE, epoxy ethane and ethanol production. Compatible with swing-reactor and high-pressure tubular processes. Our ethylene is supplied in high-purity grades (≥99.9% polymer-grade, ≥99.5% chemical-grade) via ISO-certified cylinders, backed by a reliable gases supply network to ensure consistent delivery to your operations.

Propane, a colorless, odorless, and highly flammable alkane (C₃H₈), is a cornerstone of liquefied petroleum gas (LPG) with a boiling point of -42°C, enabling efficient storage and transport as a liquid under moderate pressure. Propane is renowned for its high calorific value (50.33 MJ/kg) and clean combustion properties, making it an ideal choice for high-temperature brazing, metal cutting, forklift fuel, and LPG blending. Supplied in ISO-certified cylinders or bulk tanks through our dependable gases supply network.

Sulfur dioxide (SO₂), a colorless gas with a pungent odor and high water solubility, is a versatile inorganic compound widely used in chemical manufacturing, pulp and paper processing, and as a food desiccant and preservative. It is also commonly used in sulfuric acid production and in the desulfurization of natural gas and oil. With a boiling point of -10°C, it serves as both a reactive intermediate and a functional additive, though its environmental impact as a primary air pollutant requires stringent handling. Our SO₂ is supplied in ISO-certified cylinders.

Ethylene oxide (C₂H₄O), a colorless, flammable gas with a faintly sweet odor, is a highly reactive epoxide critical to modern industrial and medical applications. It is primarily used for the cryogenic sterilization of disposable syringes, endoscopes, and pacemakers. With a boiling point of 10.4°C, it transitions to a liquid below this temperature, exhibiting excellent miscibility with water, ethanol, and ether. Its explosive range (3–100% in air) and carcinogenicity (Class 1B per IARC) necessitate stringent handling under NFPA 704 protocols (Health 4, Flammability 3). Supplied in ISO-certified cylinders or nitrogen-diluted blends.

Methane (CH₄) is a colorless, odorless, and non-toxic organic compound with distinct physical characteristics. Under standard temperature and pressure (STP), methane exists as a gas with a density approximately 0.55 times that of air, making it lighter and minimally soluble in water. It transitions to liquid at -161.5°C (boiling point) and solidifies at -182.5°C (melting point), remaining gaseous under ambient conditions. Methane is commonly used as a fuel for heating, cooking, and power generation. Because it is an odorless hydrocarbon gas, it is often mixed with substances that have an odor to report leaks or spills in pipes and systems.
