Learn more about PTFE:
PTFE is a kind of excellent chemical resistance and resistance to high and low temperature fluorocarbon chemicals, even when it is exposed to the air also can't bad,PTFE showed high chemical stability, resistance to almost all the invasion of the acid and alkali chemical material such as, outstanding is not sticky, abnormal lubricity and excellent electrical insulation properties, aging resistance and radiation resistance, small water absorption characteristics are known as "plastics king".Widely used in aerospace, petrochemical, machinery, electronics, electrical appliances, construction, textile and other fields.It is because of these features, it appeared was secret applications in military industry, it was not until the 1950 s application to static seal, compared with general spiral seal, it is a kind of very good elastic sealing material.
Each ptfe dn150/dn300 butterfly valve into one bubble plastic bag,several pcs into one wooden case.
Wooden packing will protect the goods from damage during transportation.
