Nitrile rubber is a synthetic polymer material copolymerized from acrylonitrile and butadiene. Its performance hinges on its acrylonitrile content-higher content results in stronger resistance to oils, solvents, acids, and alkalis, but slightly reduced elasticity. Typical medical/industrial grade nitrile gloves typically contain 33%–41% acrylonitrile, striking a perfect balance between protection and fit.
This molecular structure naturally repels non-polar substances (such as engine oil, diesel fuel, and alcohol), while providing stable resistance to weak acids and alkalis. Unlike latex, it is not prone to causing allergies, and unlike PVC, it is not easily prone to hardening and cracking. Therefore, it is widely used in various scenarios such as food contact, auto repair shops, laboratories, and cleaning and disinfection, making it a rational choice that balances safety, hygiene, and operational dexterity.
I've used many gloves before. Thin ones tear easily, latex gloves cause itchy hands after prolonged wear, and PVC gloves are stuffy and slippery... Until I switched to these blue, thickened nitrile gloves, the tactile sensation on my fingertips remained clear. Screws didn't slip, and when removing the oil filter, oil stains didn't penetrate. They peeled off easily after washing my hands, leaving no adhesive residue. When baking, I wore them while kneading dough and dispensing sauces, and there was no stickiness or odor throughout the process.
