Oxygen, although a sustainer of life, can have adverse effect on plastics and many other systems during their processing, storage and usage. Antioxidants are used to retard the reaction of organic material with atmospheric oxygen, which can cause degradation. Virtually all polymeric materials undergo oxidation reaction. Oxidation can occur at any stage of the life cycle of a polymer, i.e.
During manufacturing During processing During storage In the end product
HICHEM ADH is useful as a curing agent in one pack-epoxy, heat curable resins suitable for encapsulating electronic components.
Epoxy and Vinyl esters cured with HICHEM ADH have higher heat and alkali resistance.
Solvent free, aqueous printing ink compositions consisting of acrylic-polyurethanes, cured with HICHEM ADH have good alkali and weather resistance.
HICHEM ADH is effective as a quenching agent for formaldehyde in decorative coatings, floor constructions materials and wooden boards/veneers. It reduces emission of free-unreacted formaldehyde and hence bad smell.
Particularly useful for engineering plastic including, polyesters, polycarbonate, polyamide and acrylics, thermoplastic polyurethane, PVC, styrene and copolymers, polyolefins, adhesives and many other organic substrates.
HITEX-OB1
A highly effective fluorescent whitening agent in a variety of polymer substrates, especially polyester and polyamide fibers as well as polycarbonate, acrylics, styrene homo & copolymers including ABS, polyolefins and EVA.
raw material for most chemical blowing agents, polymerisation initiators and pharmaceutical intermediates. Oxygen scavenger thereby protecting steam and hot water systems. Hydrazine derivatives are used in the manufacture of herbicides, fungicides and plant growth regulators.
All polymers when exposed to natural sunlight, get degraded by photo-oxidative process. It is the selective band of light i. E. , 290-400 nm which is responsible for the deterioration of polymers. It is also called ultra-violet region of light, that is responsible for causing all the harmful effects associated with uv-radiation.
There are various ways to protect the polymer against uv light. The main groups of chemicals, which by varying actions are classified as light stabilisers and these are :
Pharmaceautical intermediate, pesticidal Intermediate, photographic chemical intermediate and corrosion inhibitor.
1,2,4-TRZ
1H-1,2,4- Triazole
288-88-0
Pharmaceutical intermediate, cross-linking agent and corrosion inhibitor.
DMTD
2,5-Dimercapto-1,3,4-thiadiazole
1072-71-5
Photographic chemical intermediate, used in lubricant, anti-foulant additive, vulcanising agent, corrosion inhibitor and to promote antistatic properties.
