PVDF – Polyvinylidene Fluoride
PVDF (Polyvinylidene Fluoride) is a high-performance fluoropolymer valued for its excellent
chemical resistance, thermal stability, and mechanical strength, even in demanding
environments.
Its unique balance of properties—durability, purity, low permeability, and strong aging
resistance—makes it suitable for applications requiring long-term reliability.
At Frexim International, we supply a full range of PVDF grades for molding, extrusion, coating,
membranes, and precision industrial components.
Through our strategic partnership with Shandong Dongyue, one of the world’s leading fluoropolymer
manufacturers, we ensure consistent quality, certified specifications, and a secure long-term
supply chain.

Key Properties

◉ Outstanding chemical and corrosion resistance
◉ High thermal stability and flame resistance
◉ High purity and very low extractables
◉ Excellent mechanical strength and fatigue resistance

FEP – Fluorinated Ethylene Propylene
Our FEP is supplied directly from Shandong Dongyue, a long-established fluoropolymer
producer with fully certified production facilities and tightly controlled specifications.
This ensures stable supply, traceability, and highly consistent performance across batches,
which is essential for industrial and high-reliability applications.
FEP is a melt-processable fluoropolymer, combining excellent chemical resistance, high
dielectric strength, and thermal stability.
Unlike PTFE, FEP can be processed using standard thermoplastic equipment, enabling the
production of thin-walled, transparent, and complex components with excellent surface quality.
Grades are primarily selected based on Melt Flow Rate (MFR), depending on the required melt
strength, extrusion behavior, and production speed.

Key Properties

◉ Chemically inert and non-stick surface
◉ Continuous service temperature up to ~200–260°C
◉ Low dielectric constant and low dissipation factor (excellent electrical insulation)
◉ High transparency relative to other fluoropolymers
◉ Suitable for extrusion, injection molding, film & tubing production
◉ UV and weather resistant, enabling long outdoor service life

Main Applications

◉ Wire and cable insulation (aerospace, data, telecom, high-frequency)
◉ Tubing and fluid transfer lines in chemical and semiconductor environments
◉ Chemical-resistant components (valves, pump housings, linings, fittings)
◉ Films, sheets, and coated fabrics requiring high purity and non-stick properties
◉ Laboratory and medical components requiring inert and clean-contact surfaces

PFA (Perfluoroalkoxy)

We distribute our PFA from Shandong Dongyue, a producer with certified and stable manufacturing processes, providing consistent batch quality and traceable material
specifications.
Grades are selected according to Melt Flow Rate (MFR), depending on required melt strength,
thickness, and processing speed.

PFA is a fully fluorinated, melt-processable fluoropolymer offering high chemical resistance,
temperature stability, and a smooth, non-stick surface.

It can be processed using standard thermoplastic methods, enabling the production of complex,
high-purity components with consistent dimensions.
Key points

◉ Resistant to aggressive chemicals and solvents
◉ Suitable for continuous use up to ~260°C
◉ Very low dielectric loss, stable electrical insulation
◉ Allows extrusion, injection molding, and film processing Main applications
◉ High-purity tubing and fluid handling systems
◉ Valve and pump components exposed to corrosive media
◉ Wire and cable insulation in demanding environments
◉ Films and linings where surface cleanliness is required

PTFE (Polytetrafluoroethylene)

We closely work with biggest world’s manufacturer Shandong Dongyue Polymer Materials Co., Ltd,
and distribute its products as representative.

We offer the full range virgin PTFE resin : molding, free flow, micronized, fine powder, modified, as
well as PTFE dispersion.

Standard grades are permanently stored at one of our European warehouse in order to be reactive
and flexible for our customers’ requests.

We are also specialised in PTFE scrap. We collect our PTFE scrap from all over the world. This scrap
is sorted, cleaned up and treated at our processing facility.

If you are looking to sell your scrap of any kind or you wish to purchase a special type of scrap, we are
interested in long-term cooperation.

Thanks to our long-standing local presence in China and our close relationship with Shandong
Dongyue, the leading fluoropolymer manufacturer in the country, Frexim International has built a
strong and reliable supply chain for semi-finished and finished fluoropolymer products.

Over time, we have developed dedicated production partnerships with selected manufacturers of
PTFE, FEP, PVDF and ECTFE components, as well as specialized machinery for processing these
materials. This allows us to offer a complete portfolio, from raw material to engineered parts,
supported by consistent quality standards and technical expertise.

Our business unit manages sourcing, production supervision, quality control, and international
logistics, ensuring that our customers receive high-performance materials and finished products
with reliable lead times, competitive conditions and stable quality.

We export to customers worldwide and support long-term industrial programs in coatings, chemical
processing, filtration, sealing, energy, and advanced manufacturing.

At Frexim International, we believe in building partnerships based on trust, transparency and
consistency — delivering the right product, at the right quality, at the right time.
