What is the difference between Lijiejing low-chloronitrile gloves and other brands of low-chloronitrile gloves?

There may be differences between Lijingjing low-chlorine nitrile gloves and other brands of low-chlorine nitrile gloves in the following aspects:

Production process and quality control

• Lijingjing: The production process is strict. For example, the 12-inch low-halogen nitrile gloves designed for 8-inch and 12-inch wafer manufacturing under Suzhou Lidel’s “Lijingjing” brand have a halogen content of <500ppm. The chloride ion content of 9-inch anti-static low-chlorine nitrile gloves is less than 300ppm and has passed ESD S20 certification. In the simulation test of the dust-free workshop, the low dust and low particle release is far below the industry threshold.

• Some other brands: Some brands are limited by production equipment and processes, and may not be ideal in terms of dimensional accuracy, surface flatness, etc. The testing equipment and technology are limited, the testing items are not comprehensive, and the product quality stability may be poor.

Raw material control

• Lijingjing: Strictly select raw materials such as nitrile rubber and additives with low halogen content to control the halogen content from the source.

• Some other brands: Due to the restrictions of procurement channels and costs, the quality of raw materials of some brands varies, the stability and consistency of low-chlorine properties are slightly inferior, and the performance of gloves in different batches may fluctuate.

Performance

• Lijingjing: It can significantly reduce ion contamination, reduce the photolithography loss of 12-inch wafers to 1.8%, and increase the yield rate of 12-inch silicon wafers by 18%. According to the verification of the front-end photolithography process of SMIC Shenzhen Fab Plant, there was no abnormal shutdown due to static electricity for 6 consecutive months, and the particle precipitation data was better than the SEMI E129 standard.

• Some other brands: Although they may meet the basic requirements in terms of protection performance, cleanliness, and static electricity control, the indicators achieved are not as good as Lijingjing, or the performance is not stable enough under some extreme conditions or in long-term use.

Market positioning and services

• Lijingjing: Focusing on the high-end market, it provides customized services and professional technical support for industries with extremely high product quality requirements such as electronics, semiconductors, and pharmaceuticals.

• Some other brands: Their products cover the high, medium and low-end markets, and some of them focus on meeting the basic protection needs of ordinary industrial production. They have gaps with Lijingjie in terms of brand building and after-sales service, and their competitiveness in the high-end market is relatively weak.
