Claims19
A noise-reducing composition comprising a thermoplastic elastomer-wollastonite composite, wherein
- the thermoplastic elastomer is selected from thermoplastic polyurethane,
- thermoplastic vulcanizates, thermoplastic polyamides, thermoplastic styrenics,
- thermoplastic copolyester and combinations thereof;
- and the thermoplastic elastomer-wollastonite composite comprises wollastonite in an amount of from about 30 to about 45 weight percent based on the total weight of the thermoplastic elastomer-wollastonite composite and having a BET surface area in the range of from about 0.2 to about 3.0 m2/g.
