PTFE as anti dripping for thermoplastics.

PTFE as anti dripping for thermoplastics.

PTFE as anti dripping for thermoplastics.

(OP)
We'd like to better understand the action of PTFE powder when used as anti dripping additive in thermoplastics like ABS, PC/ABS blends, PBT, etc.
Particularly the type of PTFE that has the best effect and which charactericts should be chosen: High molecular weight, physical form, etc.?

Does the effect of PTFE as anti dripping expire after a certain time (one year)? Thanks to all of you in advance.

RE: PTFE as anti dripping for thermoplastics.

You can use PTFE powder as a antidripping filler just because PTFE is one of the most porous plastics. The best powders are for this reason the types with the highest porosity and a big diameter.
Ask Du Pont ore Dyneon for there specifications.
Best regards,
Ernst
