DERAY^®-PTFE

​Modified crosslinked fluorpolymer

High shrink ratio PTFE heat shrink tubing specially designed for protecting applications in extreme electrical, chemical and thermal environments.

Features and Benefits

• Highly flame retardant
• Semi-rigid
• High shrink ratio
• Chemically inert
• Shrink ratio: 4:1
• Continuous operating temperature: -65°C to 260°C
• Shrink temperature: 340°C

STANDARDS

• CNES approved and listed in Matrex database
• ECSS-Q-ST-70-02

Typical Applications

• Extremely suitable for insulating and protecting objects from thermal load and chemical influence
• PTFE's excellent dielectric properties make this an ideal material for covering, protecting, and insulating wire harnesses and other bundled electrical cables
• Areas where an extreme low coefficient of friction is required
• Used to cover hydraulic hose and couplings to prevent contamination and corrosion

Ordering

Select a dimension which will shrink snugly over the application to be covered. If recovery is restricted the resultant wall thickness will be less than specified.

• Select options:
  • Color: Clear (CL), Black (BK) against MOQ
• Please specify the product name, order number and options you require
• Order example: DERAY®-PTFE 4:1, 0250 or 6.35/1.6, clear
