What types of foaming agents can be used for rubber foam production?

Two types of foaming agents (physical and chemical) can be used for rubber foam production, each having pros and cons. In general, physical foaming agents (PFA) are inexpensive and do not leave any solid residues which might affect the color or properties of the polymer.

What are foaming agents?

Type and Amount of Foaming Agents cal and mechanical properties, as well as uniform cell structures. An accurate control of ]. Two types of having pros and cons. In general, physical foaming agents (PFA) are inexpensive and do not leave any solid residues which might affect the color or properties of the polymer. On

How to make foamed rubber articles?

For the production of foamed rubber articles an optimum dispersion of the foaming agent in the matrix is very important. On this basis we recommend our foaming agent powders which are coated with special dispersing agents for a better processing. Our portfolio also includes foaming agents predispersed in EPDM for an easy handling.

What are the additives in rubber foams?

Another important additive in rubber foams is incorporation of nanofillers which can act as nucleating agents to control the foam porosity .

How do you control a rubber foam structure?

An accurate control of the foam structure directly depends on the proper selection of foaming and curing agents to achieve a balance between gas production and degree of curing . Two types of foaming agents (physical and chemical) can be used for rubber foam production, each having pros and cons.

What makes a good foaming agent?

A good physical foaming agent should be nontoxic, nonflammable, odorless and noncorrosive with high vapor pressure and solubility. They must also be thermally stable and chemically inert and must not affect the physical or chemical properties of the rubber matrix.
