Materials Compatibility

Testing of 3M™ Novec™ 7000 Engineered Fluid demonstrates compatibility with a wide range of metals, plastics and

elastomers. The materials listed below were deemed compatible by 48-hour Soxhlet extraction testing.

Novec fluids are, in general, compatible with metals, glasses, ceramics and “hard, machinable” polymers. Material

compatibility testing for “soft” or elastomeric polymers in Novec fluids is primarily focused on two effects: the extraction

of mobile organics such as plasticizers from the polymer and the absorption of the fluid into the polymer. The former is

associated with hardening or shrinking of the polymer and the latter with swelling and softening of the polymer or

diffusion of the fluid through it. Novec fluids are unlikely to swell common hydrocarbon elastomers such as EP, EPDM,

nitrile and butyl. Other materials, such as highly fluorinated or silicone elastomers, are prone to absorption and swelling.

Material compatibility testing can be used to quantify these effects. This testing reveals significant variation in the

extractable content of elastomers within any elastomer category. Application experience reveals that not all applications

are equally sensitive to dimensional and hardness changes. For these reasons, material compatibility should be treated

on a case-by-case basis at the discretion of the system designer with the specific application in mind. 3M has tested a

wide range of materials and can assist with compatibility testing and materials selection.

3M™ Novec™ 7000 Engineered Fluid is compatible with most metals and hard polymers such as:

Metals

Plastics

Elastomers

Aluminum

Acrylic (PMMA)

EPDM

Copper

Polyethylene

EPR

Carbon Steel

Polycarbonate

Polyurethane

Stainless Steel

Polyester

Fluorosilicone

Brass

ABS

PEEK

PTFE

(1) As with most fluorinated liquids, Novec 7000 fluid will absorb into fluorinated plastics (e.g. PTFE) and elastomers (e.g. FFKM, FKM types) over

longer exposures. Absorption and swelling of silicone rubber are also observed. Not all formulations of these polymers are compatible, contact a 3M

Application Development Engineer for help in product selection.

(2) Some surface oxidation of copper during testing.

Heater Selection

The critical heat flux of Novec 7000 fluid was found to be ~18 W/cm

when boiling from a horizontal 0.5 mm diameter

platinum wire in a quiescent pool of saturated fluid. The maximum heat flux obtainable in any application depends strongly

upon the geometry and flow conditions. Exceeding this heat flux can lead to thermal decomposition of the fluid. Please

consult 3M technical service engineers if you are unsure about your application.

Other Application Notes

The usage life of 3M fluids is virtually indefinite if it is kept clean, contained, uncontaminated, and used within 3M

suggested operating conditions. This list of common materials and equipment suggestions will help in fluid applications.

• Pumps - canned or magnetically driven pumps, avoid rotating shaft seals.

• Fittings - compression or flare fittings, NPT fittings with a compatible thread sealant, barbed fittings and quick disconnects

may require some evaluation before use.

• Halogen leak detector will detect fluorinated fluids and will help to Identify leaks and help reduce or eliminate fluids loses.

• In most applications used fluid can be filtered with activated carbon for solubilized hydrocarbons, activated alumina for

decomposition products, silica gel for water and polyethylene/polypropylene or PVDF filter for particulates.

Safety & Handling

Before using this product, please review the current product Safety Data Sheet (www.3m.com/SDS) and the

precautionary statement(s) on the product label. Follow all applicable precautions and directions. This product does not

display a closed cup flash point and therefore is not classified as a flammable liquid.

Environmental Properties

3M™ Novec™ 7000 Engineered Fluid has zero ozone depletion potential. Additionally, the hydrofluoroether component

of this product has negligible photochemical reactivity and therefore does not appreciably contribute to ground-level

smog formation. As such, that component is not defined or regulated by the U.S. EPA as a volatile organic compound

(VOC). See 40 CFR 51.100(s).

3M recommends that users of 3M™ Novec™ 7000 Engineered Fluid further limit emissions by employing good

conservation practices, and by implementing recovery, recycling and/or proper disposal procedures. In general, 3M

recommends that fluorinated fluids be disposed of by incineration at a permitted industrial waste facility capable of

handling halogenated materials, in accordance with all applicable local, regional, national, and/or international

regulations. See product SDS for further details. 3M also offers a Used Fluid Disposal Program.

Used Fluid Disposal Program

As part of 3M’s commitment to product stewardship and customer service, we offer the 3M Used Fluid Disposal Program

for free pickup of used 3M fluids in the U.S. This program is provided through Clean Harbors Environmental Services.

Working with Clean Harbors will ensure that your used 3M fluids will be managed properly and responsibly. A minimum

of 30 gallons of used 3M fluid is required for participation in this free program. Amounts of less than 30 gallons will be at

your own expense and will be determined based upon quantity and approved profile of waste.

For additional information on the 3M Used Fluid Disposal Program, send an email to 3Musedfluid@cleanharbors.com.

Storage and Shelf Life

The shelf life of 3M™ Novec™ 7000 Engineered Fluid is 24 months from the date of manufacture when stored in the

original packaging materials and stored at 21°C (70°F) and 50% relative humidity.
