Partes sub polyurethane pro antlia faecum ex polyurethano (PU breviter) fiunt, et meliorem efficaciam quam partes sub gummi naturali in transportatione faecum habent, praesertim in condicionibus difficilibus cum corrosivis et abrasis.
Comparata cum materia naturali gummi, materia PU haec commoda habet:
Wide range of hardness- shore A 10 – shore D 64;
Excellens resistentia attritionis cum diuturniore vita laboris;
Excellens resistentia hydrolysis, resistentia oleo, acidis et alcali;
Flexibilitas excellens, resistentia impacti et absorptio impetus;
Coefficiens frictionis humilis
It is proved that the work life of PU is longer than Rubber materials for 3~5 times, which greatly reduces the replacement frequency and issues during the pumping.
