Semiconductor & Electronics

Of all the industries in which engineering plastics can help engineers solve design problems, none is more challenging than the semiconductor industry. Our semiconductor industry plastics are designed with the industry's often rigid and demanding environmental concerns in mind. In addition to this, our semiconductor industry specialists work directly with engineers to understand the unique challenges associated with every aspect of the semiconductor manufacturing process - from the beginning of the wafer processing cycle, through chip processing and handling, to packaging.

Each stage of the process offers its own set of difficulties, from extremely high temperatures, to exposure to highly aggressive chemicals, contact with abrasive solvents and environments of plasma under a vacuum. Ensinger has a plastic semiconductor solution to suit every environment and meets the strictest requirements for design and machining tolerance, outgassing, and contamination specifications. Our design solutions cost less than traditional materials, such as ceramics or quartz, and are generally much easier to work with.

oil & gas

The oil and gas industry demands high temperature, high pressure (HTHP), high mechanical strength and chemical resistance materials, suitable for the most extreme environments. Modern technical plastics have a major contribution to make towards improving existing solutions in the oil and gas industry due to state-of-the-art materials that offer a greater range of benefits.

Yongbang plastic has invested heavily in research and development to find innovative solutions to new technical challenges. With expertise in developing and manufacturing high performance and engineering plastic materials, Yongbang’s product portfolio has been enhanced to meet the specific requirements of the oil and gas industry, suitable for a wide range of applications.

With extensive experience in the oil and gas sector, Yongbang works closely with customers to achieve the optimum solution to suit their application's requirements. Technical material experts can provide customers with a qualified material recommendation, which can be confirmed by practical testing.

Current systems in place in the oil and gas sector largely use modern materials such as Torlon PAI, TEFLON (PTFE), PEEK and Ultem (PEI). The defined electrical properties of these polymers enable specific design of components. In addition to this, Yongbang’s PEEK (PEEK) products are tested in accordance with EN ISO 23936-1 and NORSOK M-710, which verifies the material's resistance to the severe conditions of the environment it will be exposed to. Typical applications such as hydrophone housing, seals, valve seats, back-up rings, bushings and gears can benefit from the weight reduction, corrosion resistance, thermal de-coupling and minimised noise emissions provided by these materials.
