Polypropylene - PP 20% Calcium Carbonate Filled

Polymer Type

Thermoplastic

Advantages

Better elongation at break, notched izod impact strength and lower cost than 20% talc filled PP.

Disadvantages

Reduced modulus, tensile strength and HDT compared with 20% talc filled PP. Poor surface appearance compared with unmodified PP.
