Whakapumau Maama Mahinga Nui DB886
Ko te tohu DB 886 he kohinga whakapumautanga UV tino mahi i hangaia mo nga punaha polyurethane (hei tauira, TPU, CASE, RIM nga tono pahuka ngawari). Ko te DB 866 he tino pai ki te polyurethane thermoplastic (TPU). Ka taea hoki te whakamahi i te DB 866 i roto i nga paninga polyurethane i runga i te taratara me te papa me te hiako waihanga. Ko nga tono DB 886 e whakarato ana i te pumau o te UV ki nga punaha polyurethane. Ko te kaha ake o te kaha ki runga i nga punaha whakapumau UV tikanga he tino... -
