Dry box long gloves suitable for glove boxes, mainly made of: butyl rubber, chloroprene rubber, ethylene propylene diene monomer (EPDM), CSM, latex, etc. There are significant differences in performance and price. So, for glove boxes that require water and oxygen levels below 1ppm, which material should be used?

Butyl rubber glove is the best choice!

Main reasons are as follows:

1. Butyl has extremely low permeability to water, from the schedule of the permeability coefficient, butyl rubber is lower than other rubber permeability to water 1 to 2 orders of magnitude. For maintaining long-term stability is less than 1 PPM of water value, is the best choice. The only product that can compete with butyl is fluororubber. However, due to its high manufacturing difficulty, fluororubber dry box gloves are several times more expensive than butyl ones and are basically not used in the market.

2. Even top honeywell butyl gloves, mounted on a common simplex a glove box, whether or not the glove box is in operating state, infiltrate the glove box water per hour also has 2 to 3 PPM, for solid-state batteries on the application of water content is very strict, butyl is the only option.

3. Butyl has excellent properties and a wide range of chemical protection, resistant to strong acid and alkali, esters, aldehydes and ketones and other organic solvents.
