DBSM450
Description: DAFLON SM450 is a dual wall shrink and melt PTFE tubing which gives a tight, moisture-proof seal. It is made from two types of PTFE. The outer wall is TFE and the inner lining is FEP. When heated to 400°F, the FEP melts, and at 621°F the TFE wall shrinks tightly. The FEP is squeezed into a solid or near solid mechanical encapsulation.DAFLON SM450 tubing protects against most environmental hazards involving pull, vibration, moisture, chemicals, etc. It may be used over wires, terminals, splices, connectors and as a strain relief and end cap.
The outer wall meets MIL-I-23053/12. PTFE resins meet UL94 V-0.
Operating Temperature: -100 to +450°F.
This series is RoHS compliant.
