In semiconductor, precision electronics, photovoltaic, and pharmaceutical precision assembly workshops, workpiece slippage is a long-standing, hidden challenge that affects production yield. Silicon wafers have smooth, flat surfaces, while micro-screws and chip leads are tiny and lightweight. Combined with IPA alcohol and cleaning solutions left behind from wet processes, a lubricating layer can easily form on the surface of workpieces. Standard fully smooth nitrile gloves lack sufficient friction, leading to issues such as grip slippage and parts slipping out of hand under both dry and wet conditions, which in turn trigger a series of production defects.
Industry research data indicates that 31% of wafer chipping, bent leads, and dropped micro-components in semiconductor packaging facilities are related to insufficient anti-slip performance at the fingertips of gloves. In wet processing scenarios involving liquids, the failure rate due to slipping with standard smooth-surface gloves can reach 67%. Wafers slipping from the hands and colliding with surfaces can easily result in the entire batch being scrapped, while the loss of micro-components can trigger production line shutdowns for sorting, significantly increasing production costs and time losses in the workshop. To address the industry’s anti-slip challenges in both dry and wet operating conditions, Li Jieqing has launched finger-tip zoned micro-textured anti-slip nitrile gloves. By utilizing a quantifiable coefficient of friction, these gloves balance grip stability with fingertip sensitivity while supporting multi-dimensional performance requirements—including Class 100 cleanroom compliance, anti-static properties, and low ion emission—making them suitable for various precision cleanroom processes.
Steady Improvement in Slip Resistance for Both Dry and Wet Conditions
Slip resistance testing is conducted strictly in accordance with industry standards, covering the two mainstream production scenarios: dry, dust-free environments and alcohol-wet conditions. This allows for a direct comparison of the performance differences between Li Jieqing’s fingertip-textured gloves and conventional smooth-surface nitrile gloves. The product features a structure with a textured fingertip and a smooth palm—a design better suited to industry needs. Fine anti-slip textures are applied only to the fingertip grip area, while the palm and cuff remain smooth and flat. This enhances slip resistance while reducing the risk of dust accumulation in the textured areas, meeting the control requirements of high-grade cleanrooms.
In wet conditions such as liquid cleaning and alcohol wiping, liquids on the workpiece surface significantly reduce glove friction. Conventional smooth-surface gloves have a wet friction coefficient of only 0.28, making it difficult to maintain a stable grip on workpieces. The fine grooved structure of Li Jieqing’s textured-tip gloves traps trace amounts of liquid, creating a stable micro-suction cup effect. The wet friction coefficient is consistently maintained at 0.79—double that of conventional gloves. In repeated testing involving alcohol-soaked handling cycles, there were no instances of slippage or impact damage to equipment or workpieces. On-site data from photovoltaic silicon wafer production facilities shows that switching to textured anti-slip gloves reduced defects caused by wet wafer slippage and impact. Additionally, the fingertip texture undergoes a refined chlorination process, eliminating burrs and sharp edges to prevent scratching of photolithography circuits and chip pads, meeting the requirements for gentle handling of precision components.
Balancing Slip Resistance and Tactile Sensitivity
Most anti-slip gloves on the market are made of stiff materials that feel stiff when bent and offer a dull tactile response, making them unsuitable for high-precision processes such as photolithography fine-tuning, probe alignment, and SMT micro-component soldering. Li Jieqing has specifically introduced dual-thickness options to accommodate different production scenarios, balancing slip resistance with operational sensitivity.
The 0.08mm ultra-thin textured-tip version is suitable for high-precision workstations such as photolithography inspection and microscopic assembly. With uniform wall thickness at the fingertips and smooth flex-and-rebound properties, it allows for precise detection of component thickness differences at the 0.1mm level, enabling unimpeded fine manipulation. The 0.15mm standard wear-resistant version offers greater toughness and superior friction resistance, making it suitable for high-frequency operations such as wafer handling, fixture assembly and disassembly, and screw fastening. Actual durability test data shows that after 1,000 repeated bending cycles, the textured surface exhibits minimal wear, with friction decreasing by only 7%, ensuring stable performance. In contrast, standard external-particle anti-slip gloves experience extensive particle shedding after 2,000 friction cycles, resulting in a significant decline in anti-slip performance; the shed particles also easily cause secondary contamination in the workshop.
The gloves exhibit excellent overall elasticity, with an elongation at break of 520% and a tensile strength of 14 MPa. They remain flexible even during prolonged wear, allowing users to securely grip micro-fasteners while gently handling fragile wafers, thereby meeting the diverse gripping needs of precision workshops.

Clean, Anti-Static, and Chemical-Resistant—Meeting Multiple Standards
The textured surfaces of traditional anti-slip gloves tend to trap dirt and debris, posing a risk of exceeding cleanliness standards. Lijieqing leverages Class 100 cleanroom manufacturing processes to effectively resolve the industry-wide conflict between anti-slip performance and cleanliness. The product is manufactured entirely in an ISO Class 5 cleanroom and undergoes eight rounds of thorough rinsing with 18.2 MΩ ultrapure water. The interior of the fingertip grooves is free of rubber debris and mold release agent residues, and LPC particulate matter test results comply with Class 100 cleanliness standards. Combined with a powder-free chlorination process and the absence of talc filler, there is no powder accumulation in the texture crevices, eliminating additional sources of dust contamination.
Regarding core indicators of the precision manufacturing process, the product strictly controls the leaching of four key corrosive ions: sodium, chlorine, calcium, and potassium. The leaching levels of all four ions are below 0.01 μg/cm². The textured grooves are designed to prevent impurity accumulation, and no additional ions leach out under acidic or alkaline conditions. Anti-static performance is uniform across the entire surface, with resistivity at the fingertips and palms remaining stable within the standard range. There are no issues with localized static buildup, effectively reducing the risk of static discharge damaging chips. Additionally, the gloves offer excellent chemical resistance.
