Me whakamahi te whakapiri-waahanga e rua i roto i te waa e tika ana i muri i te whakaurunga ki roto RE.
Ko te roa o te waa e tika ana ehara i te mea e pa ana ki te ihirangi polymer o te whakapiri, engari ano hoki etahi atu waahanga e tika ana (penei i te resin, antioxygen, plasticizer, solvent, etc.
Ka tata ki te wa e tika ana, he maha nga haora, he ra mahi kotahi ranei, ka uaua ake te mahi a te whakapiri, ka tere te piki o te pokey.
Ka mutu, ka waiho hei tiēre korekore. 100 te whakapiri kounga, Hydroxyl polyurethane (Polyurethane kaute mo te 20%), RE horopeta 4-7. rapa Chloroprene (Rubber account for around 20%), RE e 4-7.
