AN INCREDIBLY VERSATILE MATERIAL WITH A WIDE VARIETY OF APPLICATIONS

Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene.  

Being hydrophobic, non-wetting, high density and resistant to high temperatures, PTFE is an incredibly versatile material with a wide variety of applications, though it’s perhaps best-known for its non-stick properties.

ADVANTAGES OF USING PTFE FILLED COMPOUNDS

• Excellent chemical resistance
• Wide range of service temperature
• Excellent dielectric properties
• Non stick, low friction
• No embrittlement or ageing
• Smooth surface finish can be achieved
• Non wetting
• Outstanding corrosion protection
• Electrical insulation
• High thermal stability and flame resistance
• Resistance to weathering
• Food grade compliancy

Delrin possesses several properties that make it ideal for mechanical applications and the material of choice for metal part replacement:

• High strength, stiffness, dimensional stability, and overall durability 
• Low friction and wear resistance
• High fatigue and creep resistance—resists cracks and material deformation from mechanical stress over time 
• Chemical resistances against fuels and solvents, such as gas 
• Low moisture absorption, allowing effective operation in wet environments 
• Temperature toughness

CTFE/PCTFE may be confused with other fluoropolymers such as PTFE— but the differences in the materials are quite notable. While there may be some overlap, it should be noted that CTFE/PCTFE and PTFE are each ideal for different purposes.

Choosing CTFE or PCTFE during manufacturing may be a beneficial choice for many designs. Both offer excellent stress-crack resistance and high mechanical strength. CTFE and PCTFE are frequently utilized in cryogenic valve seats, high-pressure gas seats and deals, and various electrical components. A low rate of moisture absorption ensures that CTFE/PCTFE products will maintain beneficial electrical properties even in the face of high humidity—a property that is largely unique among competitive materials. 

CTFE and PCTFE offer a wide range of benefits, such as:

• Chemical resistance
• Long-term weathering
• Non-stick properties
• Non-flammable properties
• Low dielectric constant
• Low dissipation factor
• High arc resistance
• Surface and volume resistivity
• Flexibility at low temperatures
• Thermal stability at high temperatures
• Low deformation under load stresses
• Low coefficient of friction
• Resist

exolite^® is a unique cross-linked polystyrene, microwave plastic manufactured by C-Lec Plastics Inc. This material’s most notable properties are it’s stable electrical properties into the Giga-hertz frequency range. It is also optically clear, with a slight yellow cast, when polished (approximately the same as Acrylic), dimensionally stable, and has excellent sound transmission characteristics.

As a result, Rexolite^® is often used for high-frequency circuit substrates, microwave components, and lenses with acoustic, optical and radio-frequency applications.
