POLYURETHANE - HYPALON CHARACTERISTICS

The gauntlet is made of two different and inseparable layers : Polyurethane and Chlorosulphonated polyethylene (Hypalon)

Polyurethane provides safety against mechanical risks of tear strength, perforation and breaking. The grade of Polyurethane used to manufacture, this gauntlet has been chosen for its high mechanical properties and low modulus.

Hypalon with its exceptional chemical resistance to ozone aging and acid and alkali products, protect the gauntlet from chemical hazardous products handled inside the glove box.

RESISTANCE AGAINST THERMALLY ACCELERATED AGING

According to NF T 46-004 norm

Tensile strength: < 30%
Elongation at break : < 30%

RESISTANCE AGAINST VARIOUS CHEMICAL AGENTS

After contact with liquids for 72 hours at 23°C :

	D % / initial value of the tensile strength	D % / initial value of the elongation at break
Ammonia 32%	< 25%	< 30%
Hydrochloric acid 33%	< 25%	< 30%
Sodium hydroxide à 40%	< 25%	< 30%
Nitric acid 13M	< 25%	< 30%

HANDLING ADVICE

Fitting

It is essential to fit up the gauntlet on the glove box with the chemically resistance layer of the sleeve (white Hypalon) towards the inside of the glove box and the mechanical resistance layer (blue Polyurethane) towards the operator.

This gauntlet is particularly recommended for :

Concentrated Hydrochloric acid

Nitric acid 13 N

Ammonia 32%

Sodium hydroxide 40%

It is also suitable for handling chemical products such as :

Alcohol

Low molecular weight petrol as far as Pentane

Edible oils

Mineral oils

It allows to operate in high oxidizing environment including ozone, active oxygen and free radicals.
Resistance against natural aging and ultraviolet raise is excellent.
Hypalon provides a good flame resistant to this gauntlet.

This gauntlet is not suitable for handling:

Aromatic solvents

Chlorinated solvents

High molecular weight petyrol from hexane

Plasticisers (types TBP)
