DESCRIPTION OF PTFE TFM PFA

Properties of Modified PTFE TFM PFA
Basic PTFE is a linear polymer of tetrafluoroethylene, CF2=CF2
Two co-polymers using perfluoropropylene-vinyl-ether (PPVE) as co-monomer are commercially important, these are:
TFM,a copolymer with about 0.1% PPVE
PFA,a copolymer with 3 - 15% PPVE
TFM is essentially similar to PTFE but with reduced porosity, improved tensile strength and a high degree of weldability.
PFA is a melt-processable thermoplastic with similar chemical resistance to PTFE. It has much lower porosity and is translucent.
FEP, Fluorinated Ethylene Propylene,a thermoplastic,is also a member of this family and shows the high chemical resistance characteristic of fluoropolymers along with excellent clarity
.


PFA Dissolved Sample Tanks & Sample Vials

PFA Dissolved Sample Tanks and sample Vials have been the choice of the Geochemists worldwide for sample digestion and evaporation.

Molded from the highest purity grade of virgin PFA,they are chemically insert,with ultra low trace metal content,while the flat bottom and wide service temperature range makes them perfect for use with the hotplate.

Standard tanks are widely used for the collection,storage,archiving or disposal of various substrates.Seamless design,rounded corners and wide opening allows easy transfer and removal of the entire content.

Service temperature range of PFA is -328°F to 500°F (-200°C to 260°C)

Flat surface on bottom of vial ideal for hot plate heating

Flat interior allows for large surface area for contents

The volume of the PFA dissolved sample tanks and standard tanks standard vials:7ml,15ml,23ml,30ml,50ml,60ml,90ml,120ml,180ml,200ml,240ml and so on or customer made. 


PFA Digestion Vessels & Digestion Jars

CFDPLAS has developed a line of high purity PFA sealed digestion vessels for rapid sample dissolution.

These vessels can be placed directly in a microwave oven for controlled high speed heating to drastically reduce the time required to dissolve or digest an analytical sample.

CFDPLAS digestion vessels are designed for the increasingly aggressive digestion preparation methods used in trace analytical procedures. These molded PFA digestion vessels feature ultra low metals content and are compatible with all mineral acids.

Alternatively, these vessels can be supplied with flat bottoms for hot plate heating and digestion.

Although effective, these methods can produce hazardous conditions which should only be attempted by the skilled analytical chemist with expertise in pressurized digestions.

Service temperature range of PFA is -328°F to 500°F (-200°C to 260°C)

Designed for rapid sample digestion via microwave techniques

Flat exterior for hot plate heating and digestion
