1.Molecular weight and molecular weight distribution of rubber. Rubber is a highly elastic polymer compound (with a molecular weight generally above 100,000), and thus possesses high elasticity that other materials do not have. Therefore, it is also called an elastomer. Many properties of rubber change with the increase of molecular weight （1）Rubber containing a large amount of low-molecular-weight components has a relatively low softening point and high plasticity in the softened state. (2) Rubber with a majority of high-molecular-weight components has higher strength, toughness and elasticity, and a higher softening point, but its plasticity is relatively low. (3) Rubber with a high molecular weight and a narrow distribution, although it has higher strength and other properties, is difficult to process during rubber compounding and molding, and has high processing energy consu...

In every corner of industry and life, rubber products play a crucial role quietly with their outstanding performance. Rubber hoses, with their excellent corrosion resistance and high-pressure resistance, safely transport strong acid and alkali solutions in the chemical industry and stably transfer fuel in automotive engines. Rubber seals are like the "safety guards" of equipment. With excellent sealing and wear resistance, they are widely used in the mechanical and aerospace fields, effectively preventing the leakage of liquids and gases and extending the service life of equipment. Rubber pipe fittings, in building water supply and drainage and gas transmission projects, ensure the stable operation of pipeline systems with their seismic resistance and firm connection. ​In addition to standard products, we also offer customized services. Whether it is rubber or plastic products, f...

In the petrochemical industry, the safe and efficient transportation of oil products is a key link to ensure production and supply. And the oil transfer hose, as the "lifeline" of oil transportation, plays an indispensable role in it. Today, let's take a deep look at a brand-new upgraded oil transfer hose. What kind of transformation will it bring to oil transportation? ​During the use of traditional oil transfer hoses, problems such as insufficient oil resistance, limited pressure-bearing capacity and short service life are often encountered. This not only increases transportation costs but also may cause oil leakage, resulting in environmental pollution and safety hazards. The oil transfer hose we have launched directly addresses these pain points and brings all-round upgrades with innovative technology. ​In terms of material, it adopts a composite structure of high-performan...

Did you know that rubber hoses are everywhere in our daily life and industrial production? It has a delicate structure and is generally composed of an inner rubber layer, a steel wire braided layer and an outer rubber layer. ​From daily irrigation and car washing to the industrial transportation of hydraulic fluids, alcohols, fuel oil and lubricating oil, it can be found everywhere. It is even more indispensable in industries such as petrochemicals, shipbuilding, and food and beverage. For example, water delivery hoses are used for irrigation and fire protection. Hot water and steam hoses are used for equipment cooling and food processing. Beverage and food hoses are used to transport milk, juice, etc., and must meet strict food-grade standards. ​The industrial working environment is complex and has high requirements for it. There are standards for dimensions, pressure, chemic...

Deep in the Amazon rainforest, the Indians once discovered a kind of "weeping tree" - as long as the bark was cut, the milky white SAP would drip like tears. This magical liquid is precisely the source of natural rubber. In 1876, 22 rubber saplings crossed the ocean from Brazil to Southeast Asia. Under the hard work and sweat of Chinese laborers, this land now contributes 90% of the world's natural rubber.The transformation of rubber began in 1844 when the American Goodyear invented vulcanization technology, which turned rubber from the "strange tree SAP" that became sticky when heated into a tough and durable industrial material. Today, from car tires to space shuttle seals, from medical gloves to smart wearable devices, more than 70,000 kinds of products rely on this elastic material. Chinese scientists have further broken through the technological blockade and dev...

Rubber is a kind of high-elastic polymer material and plays an indispensable role in human life. In the early 19th century, people extracted natural rubber from Brazilian rubber trees, initiating the history of rubber applications. With the development of industry, synthetic rubber emerged, making up for the deficiencies of natural rubber in terms of output and performance. ​There are various types of rubber. Natural rubber has excellent elasticity and insulation properties and is widely used in the manufacture of tires, seals, etc. Synthetic rubber can adjust its performance according to demand. For instance, nitrile rubber is oil-resistant and silicone rubber is heat-resistant, making it highly effective in fields such as aerospace and medical care. ​From car tires to medical gloves, from shock-absorbing parts to sports goods, rubber, with its properties of wear resistance, ...

From high-precision metal wire weaving to precise rubber layer coating, every process undergoes precise forging by CNC equipment and meticulous calibration by technicians. It adopts a composite structure of 304 stainless steel woven mesh and nitrile rubber, and undergoes high-temperature vulcanization at 200℃ and a pressure resistance test of 15MPa. The finished product features flexibility, vibration resistance and corrosion resistance. The production line achieves full-process traceability in accordance with the standards of Industry 4.0, with 128 quality inspection indicators strictly controlled at each level, making every hose a reliable "industrial blood vessel" in the fluid transmission system. At this moment, it is all set to go, delivering the commitment of safety and efficiency to fields such as energy and machinery.  ...
