A cost-effective foaming agent for thermoplastic resins such as polyvinyl chloride, polyolefins and styrenics is azodicarbon amide (1,1'-azobisformamide).
It produces a high gas yield and gives odorless, non-staining foams of fine and uniform cell structure.
Azodicarbonamide disperses easily in plastic compounds by conventional processing methods, although it is insoluble in common solvents and plasticizers.
There are five chemically identical grades: KEMPORE 60/14, KEMPORE 60, KEMPORE 125, KEMPORE 150 and KEMPORE 200.
Physically, the five grades differ in color and particle size, as well as rate of decomposition in the presence of activators.
Color ranges from orange-yellow for KEMPORE 60/14, to pale yellow for KEMPORE 200. Particle size is progressively smaller from KEMPORE 60/14 to KEMPORE 200.
The most coarse grade, KEMPORE 60/14, has the slowest rate of decomposition. KEMPORE 200 has the smallest particle size and the fastest decomposition rate.
In the presence of activators, it will have the fastest rate of decomposition. |
