Are chemical blowing agents a polymer additive?
Chemical blowing agents are becoming a polymer additive of significant technical importance for providing production, economic and physical improvements when processing a wide range of polymers. Stephen Quinn of Bayer describes the chemistry available, the applications and processing fundamentals when selecting a blowing agent.
Which thermoplastics use chemical blowing agents?
As well as these two materials, other thermoplastics used with chemical blowing agents include polystyrene and PET, as well as a range of rubber materials including EPDM, NBR, SBR CR and NR. The engineering thermoplastics consume little blowing agent although foamed articles are available.
Can chemical blowing agents replace PBAs?
The increasing concern about the environmental impact of physical blowing agents (PBAs) favours the use of chemical blowing agents (CBAs) to replace controversial PBAs. Blowing agents are key compounds in order to obtain polymer foams. Indeed, blowing agents are crucial additives that release gas needed to blow polymer foams.
What are physical blowing agents?
Physical blowing agents are compounds that expand quickly because of a phase change such as vaporization of liquids or of compressed liquefied gases at the foaming temperature. Table 6.2. Typical physical blowing agents for plastics
Which blowing agent is used in decomposition reaction?
The decomposition reaction proceeds in the two follow ing steps: Inorganic blowing agents are difficult to disperse in polymers; thus, in spite of their low cost, they are seldom used. Organic blowing agents offer more application possibilities. Organic blowing agents are widely used in foaming technology.
Are chemical blowing agents reversible?
Chemical blowing agents are organic and inorganic compounds that decompose thermally into gases not reacting with the polymer matrix. This process is usually exothermic and irreversible; however, certain compounds that decom pose through thermal dissociation, such as bicarbonates, evolve gas in a revers ible and endothermic reaction.
