Styrenics and Thermoplastic Elastomers

In polystyrene (PS), talc is used in combination with an elastomer to overcome reduction in impact properties (note the improvement in Table 12.6 from Ref [5]). 

Another commercial application is in PS foams, where it is used as a cell-nucleating agent. In rubber blends, talc is used as an antitack agent to prevent newly formed goods from sticking together. In some specialty elastomers, it reduces air and fluid permeability [5]. 

Other market applications of talc involving polymers outside the filled thermoplastics industry include [3, 5]
