JVF2-14 vacuum pump oil Safe and non-toxic

Product introduction

JVF vacuum pump oil is a linear perfluoropolyether polymer based on carbon, fluorine and oxygen. These three elements play an important role in this product as high-performance vacuum pump oil in vacuum pump. The thermal stability of JVF is different from that of the traditional vacuum pump because it contains hydrogen
