Molecular formula: [CF₂--CF₂]n

CAS No. 9002-84-0

Description: CGF 268 is the virgin PTFE (polytetrafluoroethylene) powder for the applications to make rods, tubing etc. by paste extrusion. Its typical end products includes wire and cable insulating coating, linings, hoses, tubing, sleevings for use with heat, steam, hydraulic fluid, etc... Preferred for the extrusion processing with reduction ratios (i.e. RR) in the range 400 : 1 to 1500: 1. Typical products are extruded small tubing or rods, e.g.  Ø 1.8 / 1.5 or  Ø 0.9 / 0.5

Typical properties :

Safety precautions

• Toxic gases will be produced when the material is heated above 260 degree C. Ventilation system must be provided in sintering areas.
• Sintering temperature should be below 400 degree C to avoid decomposing.

 Packaging, storage and transportation

• 20kg net packed in double PE plastic bags with a cardboard drum outside.
• Store in clean, cool (5-20 degree C) and dry place
• Open containers and use the material in clean environment only. 

Looking for other fine powder grades also for extruded tubing or rods ? please go for CGF 238A for lower RR at 100: 1 - 900: 1 , or find CGF 288 specifically for high RR ( 900: 1 or higher ) to make spaghetti tubing or thin rods.

For the PTFE extrusion powders for making sealing tapes by paste extrusion, please refer to PTFE powders  CGF-218 and CGF-206 ,
