KYNAR® is a proprietary brand name and a registered tradmark of AUTOFINA Chemicals, Inc. These resins are often referred to by the more general term, Polyvinylidene Fluoride or PVDF.
KYNAR®: Temp. Range – 80°F to 226°F / Pressure 260 psi @ 70°F - Autoclave
temp. to 285°F (140°C). Meets USP Class VI Requirements (US Pharmacopoeia).
FDA (Natural only)

NSF/ANSI 61 & 51 (Natural only)
KYNAR® has been used as a pipe liner in chemical processing plants since its introduction nearly thirty years ago. It has also been used extensively in the paper and paper pulp industries, where equipment is constantly exposed to high concentrations of Chlorine and Chlorine Dioxide. In these applications the permeation resistance of Kynar components has far surpassed that of PTFE.
Products incorporating PDF resins are used extensively in silicon microcircuit fabrication. Processes in this industry commonly use deionized water, a fluid that is highly corrosive to steel. The deionized water is often sanitized through the injection of ozone and exposure to UV light, both of which can seriously degrade the integrity of materials less durable than Kynar.
Medical device
manufacturers selling to customers in remote locations around the world
have found a demand for reusable tube sets and equipment incorporating
Kynar components. Because medical staffs in remote areas cannot rely on
a supply of disposable devices; components are often disassembled, sterilized,
and reassembled for use. To withstand such rigorus use, products must
be physially strong, damage resistant, and resistant to multiple radiation
or autoclave sterilization
cycles. Kynar is quickly becoming the material of choice for such workhorse
applications. In spite of its initially higher cost in comparison wirh
most other materials, its durability and long-term use potential under
harsh conditions make it much more cost-effective than disposable plastic,
Stainless Steel or PTFE. As the people of the world become more concerned
with resource management, recycling, and other environmental issues, the
reuseability of Kynar components will play an increasingly important role
in the Medical Device industry.
Eldon James
offers Natural Kynar fittings with materials and lot traceability
certificates. Most of our Natural Kynar Fittings
are certified to NSF/ANSI Standards 51 &
61. Standard 61 is a
certification for use with potable water and Standard 51 is a certification
for food and
beverage use.
Natural Kynar complies with (USP)
Class VI regulations

Appearance: opaque tan
Tan Kynar (PVDF) fittings exhibit the same physical and chemical resistance properties as Natural Kynar. These fittings contain a percentage of recycled material sourced from our Natural Kynar, virgin material production runs. A tan colorant is added to differentiate our tan Kynar fittings from Natural Kynar fittings. If your application does not require lot tracability or NSF certification, these fittings represent an excellent value. Tan Kynar fittings have excellent resistance to many chemicals and are manufactured to the same tolerances and high quality standards as all EJ fittings. To order Tan Kynar fittings simply replsce the (NK) suffix on our Natural Kynar part numbers with (PVDF).
