Vineeth Chemicals is a proprietary
company set up by a young and enterprising chemical engineer,
Mr.Vishwanath P.Shetty, M.E.(Chem.), in the year 1986.
The Company is engaged in the manufacturing of Hydrogenation
Catalysts and allied products viz. Raney Nickel Catalyst
(Active), Raney Cobalt Catalyst, Precious Metal Catalysts
viz.Palladium/ Platinum supported on inert materials such
as Activated Charcoal, Calcium Carbonate, Alumina, Barium
Sulphate, Kieselguhr etc. The company is also engaged
in manufacturing Nickel-Aluminium Alloy Powder (50:50
& 30:70) and Devardas Alloy. Company is also manufacturing
Lindlar Catalyst which is used for selective hydrogenation
of triple bond to double bond.. Raney Nickel Catalyst
(Active) is company's key product and its market share
is around 60%.
Company's installed capacity
for Raney Nickel Catalyst (Active) is around 150 tones
per annum and that of around 2400 kgs. for precious metal
catalysts. Company also undertakes reactivation of Spent
Raney Nickel Catalysts and recovery of precious metals
from spent containing precious metal catalysts which helps
the customers in a big way to bring down their cost of
operation.
Company is highly quality
conscious. The company has got its own R & D Center
where product development and improvement is an on going
activity. The R & D Center is being looked after by
highly experienced technical staff. Company has got documented
procedures and systems. Quality of company's products
on several occasions has been proved to be superior to
imported products. Company's products are accepted by
large number of companies including multinational pharmaceutical
companies.
Company's products other
than Nickel Oxide are used mainly in the manufacture of
bulk drugs, drug intermediates, aromatic chemicals, specialty
chemicals, rubber additives, pesticides, dyes and dye-intermediates,
fine chemicals and organic chemicals etc. where hydrogenation
is the key reaction. Nickel Oxide, however, is used for
imparting green shades in glass manufacture.
Company markets its products
at most competitive rates. Material Safety Data Sheets
are provided to customers for storage and handling. The
company provides after sales service and also technical
consultation to its customers.
Company is highly conscious
about prevention of environmental pollution and has adopted
mechanism to ensure environmental protection. Ever since
its inception the company has maintained excellent industrial
relations with its employees. All the employees of the
company are treated like family members. The employees
are periodically educated about house-keeping and safety
aspects pertaining to manufacturing, storage and handling
as most of the products are pyrophoric in nature.
We are leading in the manufacture
of the Catalysts like Raney Nickel, Palladium products
on Charcoal etc.
