Abstract
Sposób wytwarzania kompozycji polimerowej w procesie wtryskiwania mikroporującego charakteryzuje się tym, że do układu uplastyczniającego wtryskarki posiadającego cztery strefy grzejne, zasypuje się mieszaninę polipropylenu w ilości od 87,5% do 93,5%, korzystnie 90,0%, środka mikroporującego w postaci mikrosfer o egzotermicznej charakterystyce rozkładu w ilości od 1,5% do 2,5%, korzystnie 2,0% oraz mikrocząstek żelaza w postaci proszku w ilości od 5% do 10%, korzystnie 8%, po czym nagrzewa się powstałą mieszaninę do temperatury w strefie pierwszej 200°C, w strefie drugiej 210°C, w strefie trzeciej 220°C, w strefie czwartej 230°C, następnie wtryskuje się mieszaninę w czasie 5 s do formy wtryskowej o temperaturze 25°C pod ciśnieniem 100 MPa, po czym chłodzi się mieszaninę w formie wtryskowej w czasie 25 s.
