n  Chemical Blowing Agent (CBA)

Blowing agents, be defined as compounds which are thermally unstable and decompose to yield gas at the desired polymer processing temperature, are widely used to expand rubber, plastics to create foam. Most of the chemical blowing agents are organic chemicals, while inorganic chemicals are few.

In accordance with the decomposition mechanism, CBA are generally subdivided into two major categories: exothermic and endothermic. Customers can select the suitable type according to the environmental conditions and actual use.

Many advantages of foamed products can be achieved by choosing the right blowing agents, such as:

²  raw materials and cost saving

²  density reduction

² weight reduction

²  thermal insulation

² noise absorption

²  easy to process

²  impact and shock absorption

²  good looking and comfortable feel.etc


n  Azodicarbonamide(ADC)

Among all industrial blowing agents, ADC is the most economical and most widely applied organic chemical blowing agent. ADC is a type of yellow or light yellow crystal in powder form. Its specific gravity is 1.65 and is nontoxic and odorless. WELLCELL™ADC has good dispersibility, large gas yield and nontoxic decomposition products. It is odorless and non-pollutive, and is mainly used for production of closed-cell foam products. Pure ADC decomposes between 200-210℃. By adding some activating agent to ADC will lower its decomposition temperature down to 150℃ or even lower, which further enlarges its application fields.
