What are Changda International Holdings's Business Segments?
Chemical Products
Products
Our principal chemical products are snow melting agents, flame retardant, and
various other industrial chemicals. Snow melting agents are de-icing salt, consisting
of a combination of sodium chloride, calcium chloride, magnesium chloride and
additives in varying levels for different customer segments and uses. The snow
melting agents are a white, odorless and soluble solid compound and are used primarily
to de-ice airports, roads and golf courses in the winter seasons, spread by winter
service vehicles.
Our industrial chemical products range includes flame retardant, thiophene, calcium
chloride and magnesium chloride. Thiophene is a colorless and transparent liquid
which is primarily used in the pharmaceutical raw materials industry as a medicine
chemical auxiliary, and for the synthesis of anti-bacterial fungus. Calcium chloride
and magnesium chloride are used for dust control on roads and also as essential
product ingredients for a wide range of industrial usage such as in cement production.
Our new flame retardant product is Hexabromocyclododecane (HBCD or HBCDD). It
is a brominated flame retardant which consists of twelve carbon, eighteen hydrogen,
and six bromide atoms tied to the ring. Its primary application is in extruded
(XPS) and expanded (EPS) polystyrene foam which is used as thermal insulation
in the building industry. HBCD is also used in upholstered furniture, automobile
interior textiles, car cushions and insulation blocks in trucks, butadiene-styrene
rubber, adhesive, paint, unsaturated polyester, packaging material, video cassette
recorder housing and electric and electronic equipment. When applied in EPS, its
oxygen index may be above 30, which meets with the self-extinguishing standards
set by the Chinese government. HBCD is highly efficient in this application since
very low levels are required to make the products flame retardant. Typical HBCD
levels in EPS are 0.7% and in XPS 2.5%. At present, according to China’s
Bromine Science and Environmental Forum (BSEF), HBCD is the only suitable flame
retardant for these applications. Any other kind of flame retardant would likely
need higher load levels in the polystyrene foam.
Fertilizer Products
Our organic and inorganic fertilizer products are classified into the following
categories:
Complex Fertilizers. These fertilizers contain two or three of the primary nutrients
of nitrogen, phosphorus and potassium and are made by a process involving only
chemical reactions between raw materials and intermediates.
Compound Fertilizers. Such fertilizers are produced by initiating chemical reactions
between the three primary nutrients of nitrogen, phosphorous and potassium during
the production process. We have expanded our product offerings to include a
microbial organic-inorganic compound fertilizer which (i) helps plants secure
nitrogen from the air, (ii) facilitates plants’ absorption of useful minerals
such as phosphorus and potassium from the soil and (iii) enhances stress resistance
by the plants. The combination of the organic and inorganic elements enhances
soil fertility and crop yield respectively.
Slow-Release Compound Fertilizer. This group of fertilizers allows fertilizer
nutrients to be released over a period of time, enabling plants to absorb most
of the nutrients and enhance yield rate. We have also developed controlled-release
fertilizers.
