Natural latex

This polymer offers good mechanical performance, even with minimal thickness. In particular, it has good tear and puncture resistance, and it offers good resistance to numerous acids, alkalis, alcohols and ketones.

It also has the advantage of staying supple in cold environments.

N.B.: In certain rare cases, the proteins found in natural latex can cause allergic reactions. In this event, we recommend the use of synthetic materials for sensitised users, such as a nitrile or neoprene glove.Natural latex is not recommended for use in contact with oils, greases, petroleum products, strong oxidising acids and aromatic or chlorinated solvents. The properties of natural latex can be deteriorated by prolonged exposure to light, UV or ozone.Natural latex offers exceptional flexibility and elasticity. Gloves made from natural latex adapt to the shape of the hand, thus maximizing the user's dexterity and comfort.

 

Neoprene

Extremely supple with excellent resistance to chemical contact, neoprene is an outstanding multi-purpose polymer. Neoprene offers good chemical resistance to acids, alkalis, oils, greases, alcohols, petroleum products, ketones, aliphatic solvents and numerous industrial gases and vapours). In addition, it is a supple material enabling dexterity and comfort.

It has excellent thermal properties, with contact insulation (hot or cold), and fire resistance (suitable for applications in proximity to flames). It also ages well, since it does not suffer from any deterioration, due to prolonged exposure to light, ozone, UV, etc.

On the other hand, we should point out that

neoprene has poor mechanical properties when heavily stressed in chemical environments. In those conditions, a thick glove with a cotton lining is recommended, since this reinforces the mechanical properties of the glove, and therefore, its durability. Neoprene is not appropriate for prolonged contact with strong oxidising acids and aromatic or chlorinated solvents, since these rapidly damage neoprene.

Nitrile

Nitrile, or Acrylo nitrile butadiene rubber (NBR), generally offers very good resistance to oils, greases and hydrocarbon derivatives, as well as aromatic or chlorinated solvents.

Nitrile also gives excellent abrasion and puncture resistance. It does not contain any proteins and has a very low accelerator content, therefore, it is very well-tolerated by users, paticularly for long-term wear.

On the other hand,

nitrile is a naturally rigid elastomer. Thick nitrile gloves may limit dexterity.nitrile to stiffen, which makes the glove more difficult to use. Note, that nitrile is not recommended for prolonged contact with ketones, strong oxidising acids, esters or aldehydes.

In addition, they are not recommended for cold environments (< -40°C), since these temperatures cause nitrile to stiffen, which makes the glove more difficult to use.  Note, that nitrile is not recommended for prolonged contact with ketones, strong oxidizing acids, esters or aldehydes.
