UNICELL is a trade name of the most renewed chemical foaming agents and decomposition activators, produced by DONGJIN Semichem Co., Ltd.
Chemical foaming agents are organic or inorganic plastic additives that decompose when heated to yield at least one type of gaseous decomposition product. This evolved gas produces micro-cellular materials.
Decomposition activators are organic or organometallic plastic additives that accelerate the decomposition of chemical foaming agents.
DONGJIN, having the widest range of chemical foaming agents in the world, produces 30,000 metric tons of chemical foaming agents and decomposition activators for plastic and rubber applications annually.
Many modified versions such as free-flowing, non-plating out, high expansion, self-dispersion and adjustment of decomposition temperature
for a specific process is available through DONGJIN's active research and development.

Azodicarbonamide is available in 1.8 to 25 micrometer average particle size.
It is well known as the most popular and effective chemical foaming agent for plastic and rubber applications and is one of the most widely used chemical foaming agents due to its non-toxic, self-extinguishing, relatively high decomposition temperature, and relatively large gas evolution properties.

Modified Azodicarbonamide for plastic or rubber injection and extrusion applications.
It is a very specially designed chemical foaming agent for non-staining, non-discoloring, non-plate out and odorless purpose. It is recommended for applications where steel mold corrosion, die blockage or screw build up.

Modified Azodicarbonamide for low temperature processing plastic (PVC) and rubber application. It is suitable for accelerating cure speed in a vulcanization system or line speed without extra use of activators.
DK Series release non-condensable and ammonia-free gaseous products and leave white residue. DL Series is free of creamy coloration.

This product is a completely dispersible Modified Azodicarbonamide for low temperature processing. DE3 shows better inhibition and tremendously improved whiteness in PVC plasti-sol chemical embossing application.

Modified Azodicarbonamide for EVA injection molding, EVA conventional press molding and PVC extrusion process. It is a specially designed chemical foaming agent for non-plate out, stain free and built-in nucleation purpose.
DX Series is particularly applicable for EVA shoe soles.

Modified Azodicarbonamide for chemical or irradiation cross-linked polyethylene or polypropylene application. Diverse line of chemical foaming agent is available for fine cell structure, white surface and free flowing purpose.
It is applicable for thermal insulation, floating, packaging materials, sports and leisure goods and life jackets.

Modified Azodicarbonamide for expanded PVC wall coverings.
It is specially designed chemical foaming agent for fast decomposition and white foams.

Unique Azodicarbonamide synthesized by DONGJIN's special reaction technique for plastic foams with finer cell structure and white foams.
It is applicable for floorings, wall paper, shoe soles, artificial leather, carpet underlay, sealing compound and cushioning materials where white colored and finer cell structure products are required.

MASTER BATCHES. It is a kind of chemical foaming agents master batches, composed of Azodicarbonamide or Modified Azodicarbonamide.
EVA (VA=22%) or LDPE resin may be used as a carrier and special compositions can be provided under the customer demands.

Modified chemical foaming agents based on Azodicarbonamide for plastic and rubber conventional press molding.
UNICELL-ADP Series is specially designed to be less susceptible to heat and to be free from caking troubles.
It is applicable for olefin and rubber-based conventional press molding.

As p.p'-Oxybis(benzenesulfonylhydrazide), it is outstanding non-staining, non-discoloring, non-toxic and odorless nitrogen releasing chemical foaming agent for cellular plastic and rubber application.
It is especially applicable for PVC plasti-sol, and CR foams.

As p-Toluenesulfonylhydrazide, it is an outstanding non-staining, non-discoloring, non-toxic, and odorless nitrogen releasing chemical foaming agent for cellular plastic and rubber application.
It is especially applicable for open and closed cell structure rubber foams.

As Benzenesulfonylhydrazide, it is an outstanding non-staining, non-discoloring, non-toxic, and odorless nitrogen releasing chemical foaming agents for cellular plastic and rubber application.
It is especially applicable for open and closed cell structure rubber foams.

As N,N'-Dinitrosopentamethylenetetramine, it has the oldest history as a chemical foaming agent and is one of the most economic chemical foaming agents for plastic and rubber applications.

As p-Toluenesulfonylsemicarbazide, it has relatively higher decomposition temperature than other chemical foaming agents.
Less risk of premature decomposition in the compounding stage enables it to be suitable for high temperature processing plastics such as ABS, rigid PVC, polyamide, HDPE and polysulfone, etc.

As 5-Phenyltetrazole, it is one of the most advanced chemical foaming agent for engineering plastics such as polycarbonate, ABS, polyamide and fluoro.

It is white, odorless, non-toxic and free-flowing inorganic chemical foaming agent. It releases carbon dioxide and water vapor during thermal decomposition and endothermic decomposition characteristics of UNICELL-C Series enable it to be adaptable for plastic injection and extrusion where local overheat should be avoided.

Urea-based decomposition activators. It shall be especially coated with fatty acid or metal soap to prevent from water absorption or lumping.
It activates UNICELL-D, UNICELL-OH, UNICELL-TS and UNICELL-G Series.

Zinc-based organometallic decomposition activators.
It is a especially designed decomposition activator, which is very suitable for low temperature processing application.

MICROCAPSULE or MICROSPHERE is a very unique and new foaming agent recently developed by DONGJIN.
Thermoplastic polymer shell, containing low temperature volatile liquid as a core material can be expanded more or less 5 times the original shell diameter under a fixed temperature.
It is applicable for textile, paint, print ink, wall paper and shoe injection foams.
