POMyn bolymer a geir trwy bolymeriad fformaldehyd. Fe'i gelwir yn polyoxymethylene o ran strwythur cemegol ac fe'i gelwir yn gyffredinol yn 'asetal'. Mae'n resin thermoplastig gyda chrisialedd uchel a phriodweddau mecanyddol rhagorol, sefydlogrwydd dimensiwn, ymwrthedd blinder, ymwrthedd crafiad, ac ati. Felly, mae'n ddeunydd plastig peirianneg cynrychioliadol a ddefnyddir fel amnewidyn ar gyfer rhannau mecanyddol metel.
Prif nodweddion:
- Taflen POMeiddo mecanyddol uwchraddol
- Sefydlogrwydd dimensiynol dalen POM ac amsugno dŵr isel
- Gwrthiant cemegol dalen POM, gwrthiant meddygol
- Gwrthiant cropian dalen POM, gwrthiant blinder
- Gwrthiant crafiad dalen POM, cyfernod ffrithiant isel
Cais:
Taflen POMyn cael ei ddefnyddio'n helaeth ar gyfer peiriannau llithro a chylchdroi, cydrannau manwl gywir, gerau a berynnau mewn modurol, electroneg, dillad, gofal meddygol, peiriannau, ac offer chwaraeon.
