POLYPROPYLENE COMPOSITIONS WITH A HIGH CONTENT OF HEAVY MINERAL FILLERS SUITED FOR COATING METAL PIPES |
摘要 |
<p>Polypropylene composition comprising by weight (A) 60-90% of at least one heavy mineral filler having a specific weight greater than or equal to 3; (B) 0.1-4% of a filler compatibilizer; and (C) 10-40% of a heterophasic polyolefin composition containing rubber. Said composition has an MIL ranging from 0.5 to 10 g/10 min, elongation at break greater than 100 to 800%, and flexural modulus ranging from 100 to less than 3000 MPa.</p> |
