Applications

Li-ion Batteries

Thanks to its stable and reliable performance, Solef® PVDF is widely used for electrode binder materials. It can be used as a coating layer on the battery separator to enhance performance, processability and safety. Solvent and water-borne grades are available to meet different processing requirements.

Solef® PVDF for Lithium-Ion Batteries

Oil & Gas Piping Systems

For over 20 years, Solef® PVDF has been the material of choice for flexible offshore pipelines and flexible riser systems thanks to its superior mechanical performance,  flexibility, and chemical resistance. It also meets all API17J requirements.

Solef® PVDF is also used as a fluid barrier for hot, highly corrosive, multi-phase hydrocarbon mixtures in next-generation flexible composite pipes as well as the matrix resin for the carbon fiber composite layer. As a fluid barrier for onshore flexible pipes, Solef® PVDF combines long-lasting performance with spoolability in tight bending radius pipeline systems. For the lining material in steel pipelines, Solef® PVDF  provides a reliable, cost-effective alternative to expensive, corrosion-resistant alloys.

Semiconductors

Solef® PVDF is used extensively in the semiconductor industry due to its exceptional purity. Its inherent stability eliminates the need for additives, pigments or fire retardants that can leach out.  Solef® PVDF is widely used to make pipes, tubing, and fittings and vessels used in ultra-pure water piping systems. The smooth molded surface prevents the build-up of biofilm and bacterial growth.

Wafer processing equipment is routinely exposed to highly aggressive chemicals. Solef® PVDF’s high strength and excellent chemical resistance make it ideal for distribution lines, storage tanks, valves, nozzles, protective coatings and linings.

Chemical Processing Industry

Solef® PVDF components used in chemical processing applications withstand high heat, high pressure, and harsh chemicals. Typical applications include chemical processing equipment, transport and storage systems, heat exchangers, and filtration and separation equipment (filters, membranes, housings).

Gas sampling bags made using Solef® PVDF film are inert to most gases and resist gas permeation.  Diaphragms for pumps and filters rely on Solef® PVDF film for its excellent heat and chemical resistance.

Thermoplastics Composites

Solef® PVDF can be combined with high-strength carbon fiber to produce a heat and chemically resistant, unidirectional tape ideally suited for demanding applications in the Automotive and Oil & Gas industries. 

Plumbing

Solef® PVDF is internationally-approved for drinking water (NSF61, KTW, WRAS, ACS) applications such as fittings, manifolds and sliding sleeves and offers a lead-free, non-corrosive alternative to metal. 

Membranes

Solef® PVDF is used for making durable, long-lasting membranes. Its toughness, chemical resistance and oxidative stability allow membranes to tolerate a wide variety of feed streams and cleaning methods. End application covers Waste/Drinking Water Treatment, Pharmaceutical and Medical Processing, Semiconductor, Food & Beverage Processing.

Wire & Cable

Solef® PVDF is used to insulate electric wire and cable where safety and performance are crucial. The material is highly resistant to fire, chemicals and UV rays, and it offers light-weight flexibility and low thermal conductivity.

Healthcare

Nonwoven fibers made from Solef® PVDF can be used for filtration media in N95, FFP2, and FFP3 masks being used to combat the COVID-19 crisis. PVDF can also be used for components used in single-use biopharma processing as well as coatings for surgical instruments.

Aerospace

Solef® PVDF high-performance foam used in aerospace applications offers inherent flame retardancy, chemical resistance, UV resistance and thermal stability. It is free of additives and produced without chemical blowing agents, preserving its inherent purity. 

Polymer Processing Aids

Solef® PVDF 11010/1001 improves surface quality and eliminates melt fracture issues at different concentration levels. It exhibits good thermal stability and is compatible with most polymers.
