WWG is the multipurpose chemical glass from Pfaudler’s glass range, characterized by:
3 colours, cobalt blue, light blue, and white
Extraordinarily corrosion resistant
Very high resistance to mechanical stress
Good stability against thermal shock
Homogeneous stress distribution within the glass
Inert and amorphous surface
Anti-adhesive surface
Applications of Pfaudler’s multipurpose WWG:
WWG lining is primarily used in protecting against corrosion in:
hydrolytic, chlorination, sulphonation, nitration, and bromation processes;
producing pesticides and herbicides;
acidic or leaching processes;
flue gas desulphurization instruments;
recovery, recycling of sulphuric or hydrochloric acids.
Additional advantages of white or light blue WWG:
High degree of light reflection creates a bright reactive environment and high contrast to the media.
Quick recognition of any colour shift in the process.
WWG inert and amorphous surface is a key criterion:
for the manufacture of very pure organic and inorganic substances such as vitamins, active pharmaceutical ingredients, semi-conductors or paints, and so on;
for processing and storing medicines, foodstuffs, fruit juices, and concentrates. In a comparative study involving different materials, glass lining achieves the best results for germ inhibition with regard to both natural and artificially induced germ infestation.
