Hand protection type
A
- Abrasion
Wearing down or scrapping by friction of a hard, rough material.
- Accelerator
Raw Material added to latex to boost the vulcanization rate. A formulation can include one or more accelerators.
- Alkali
Aqueous solution of a caustic, highly basic chemical (e.g.: potassium or sodium hydroxide).
- Allergy
An abnormal physiological response to a substance penetrating the body due to an over-reaction of the immune system.
- Ambidextrous
Ambidextrous gloves can be worn equally well on either hand; this is principally the case for thinner gloves.
- Anatomical
A glove is called anatomical when there is one shape for the left hand and another for the right.
B
- Butyl
Butyl offers excellent chemical resistance against ketones, acids, esters and amine derivatives. It is a supple and elastic synthetic material, allowing the user to retain dexterity if the material is not too thick. As it is quite expensive, butyl is classed as a special purpose polymer, reserved for applications requiring very high, targeted, chemical protection.
NB: butyl 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. In addition, butyl is not appropriate for prolonged contact with aromatic or chlorinated solvents, as these provoke rapid deterioration of the material.
C
- Chlorinated
Makes it easier to put on and take off gloves, without increasing the thickness and without using powder. Reduces the allergy risk of natural latex gloves.
F
- Flocked
Cotton-based textile fibres, covering the inside of the gloves. Fleeced feel providing good absorption of perspiration.
P
- Powdered
Makes it easier to put gloves on and take them off, without having to increase the thickness of the glove.
T
- Textile support
Knitted interior, made from cotton or synthetic materials for increased comfort. Particularly suited to extended tasks.
- The degradation index
The degree of deterioration of the glove, shown by an alteration of its physical properties (e.g. softening, hardening, etc.).
- The permeation time
The time taken for the chemical to penetrate the glove at a molecular level. In some cases, there is no visible deterioration of the glove.
