Product Description
PTC Alloy kuj hlau muaj nruab nrab resistivity thiab siab zoo kub coefficient ntawm esistance.
Nws tau dav siv hauv ntau lub tshuab cua sov. Nws tuaj yeem tswj tau qhov kub thiab txias thiab sdjust lub zog los ntawm kev ua kom tsis tu ncua thiab txwv tam sim no.Chemical muaj pes tsawg leeg:
