CHLOR-ALKALIS
The term chlor-alkali refers to the two chemicals (chlorine
and an alkali) which are simultaneously produced as a
result of the electrolysis of a saltwater. The most common
chlor-alkali
chemicals are chlorine, hydrogen gas and sodium hydroxide
(caustic soda). Further processing can create a variety
of chemicals...more>>
EPICHLOROHYDRIN
Epichlorohydrin (ECH) is a colourless,
mobile liquid with a characteristic chloroform-like odour,
formed by reacting chlorine obtained from the electrolysis
of brine with a lime slurry. It is employed as a raw material
for the manufacture of epoxy resins and a multitude of
glycerol and glycidol derivatives used as plasticisers,
stabilisers, elastomers...more>>
EPOXY
RESINS
Epoxy or polyepoxide is a thermosetting
epoxide polymer that cures when mixed with a catalysing
agent or ‘hardener’. Most common epoxy resins are produced
from epichlorohydrin and bisphenol-A. They have excellent
adhesion, chemical and heat resistance, mechanical strength
and electrical insulating
properties... more>>
PEROXIDES
Peroxides are chemicals that
include a double oxygen bond in their molecular structure.
The peroxide ion contains two electrons more than the
oxygen molecule, making it a powerful oxidiser. Usually
fairly unstable; peroxides readily react or decompose,
yielding oxygen. Ionic peroxides react with water and
diluted acids to form hydrogen peroxide...

PHOSPHATES
A phosphate is the naturally occurring form of the element
phosphorus, found in many phosphate minerals. It is a
polyatomic ion or radical comprising one phosphorus atom
and four oxygen.Phosphate can form many polymeric ions,
diphosphate (pyrophosphate), triphosphate, metaphosphate,
etc... more>>
SULPHITES
Sulphites are compounds that contain the sulphite ion.
Sulphites can release sulphur dioxide. They are used primarily
in photographic chemicals, food preservation, water treatment,
pulp and paper production, leather tanning, textiles,
oil drilling, as well as in the chemicals and pharmaceutical
industries... more>>
