Fact Sheet: Disposable Nitrile Gloves in Chemical Labs
Note: For the purpose of this Fact Sheet, the term "disposable nitrile gloves" refers to gloves that are one-time use and have a thickness of 5-mil and less. Examples are given in the tables at the end of the fact sheet.
Nitrile is a synthetic rubber material that offers chemical and abrasion resistance and is a very good general-duty material for gloves.

Thin, disposable, nitrile gloves are the most common gloves used when handling chemicals in laboratories; however, it is important to remember that thin nitrile rubber provides only limited chemical protection. These gloves are intended to be used only as a physical barrier against brief contact with chemicals, and they need to be removed and discarded immediately after they become contaminated.
Glove materials are evaluated on three criteria when exposed to chemicals:
Breakthrough time: This is how long it takes to detect a substance inside the glove when the outside is exposed to a chemical. A glove that holds ups for greater than eight hours is considered excellent.
Degradation: This refers to the physical changes in the material such as swelling, cracking, softening or shrinking, which occur when it comes in contact with a chemical. A glove can exhibit chemical breakthrough even if it doesn’t show signs of degradation.
Permeation rate: This is the rate at which a substance passes through a glove material once breakthrough takes place. This rate includes absorption on the surface, diffusion through the material, and desorption on the inside surface.
It is important to remember that laboratory testing data does not take into account the effects of hand movement and body temperature. The actual protection will be less for a glove that is being worn and stressed during use.

In response to the challenges faced by oversea healthcare facilities/companies to source quality gloves with FDA (Food and Drug Administration) and CE approvals in the middle of the COVID-19 pandemic. We are offering our services for sourcing powder-free/powder nitrile examination gloves and personal protective equipment (PPE), in Thailand. We hope to give our value-added services to both the buyer and seller by giving the all-necessary information, verification, quality check (third party) and use international SOP to oversee the contracts and supply chain for inspection and timely delivery. We plan to source additional contracts and create relationships with the local industry.
We are current in the final stages to sign buyer-seller contracts for a total of 220 million additional gloves that will be delivered in 2021 -2022.
