Plastic Additives for Cable & Electronics
From polymer electronical performance, to flame resistance and heat transfer, our portfolio meets all the demands of these cable and electronics applications.
Plastics for Cable Protection
VESTAMID® polyamide, VESTAKEEP® PEEK and VESTODUR® PBT used in sheathing or in cable protection tubing have protected cables for years. Continuous improvements let them always be the material of choice for the electronics and cable industry.
Polymers for Cable Insulation
Our polymers for the electronics industry can be used for cable insulation such as cable filling compounds and jelly compounds.
Polymers for Electronic Applications
We offer tailor-made polyesters, amorphous poly-alpha-olefins and liquid polybutadienes for potting compounds for electronics and cable insulation. Our range of products also covers polyester-based adhesives for electronics such as flexible flat cables.
ROHACELL® for Antennas and Radomes
Are you looking for a material for dielectric applications that combines the RF transparency of air with unrivalled processing performance at up to 190 °C (374 °F) and superior mechanical properties? Look no further: ROHACELL® rigid foam is doing the trick!
Silica for Electronics
Silica serves as antiblocking agents in the polymerization process or as additives for rheology control in circuit board production.
Silica in Illuminants
Silica effectively act as a chemistry binder in the phosphor layer of fluorescent lamps and prevent mercury pollution. Thus, the service life of fluorescent lamps is extended. In LED lamps, our silica is used as diffusion particles in LED silicon lenses.
Ultrahigh purity hexachlorodisilane used in the semiconductor industry for chemical vapor deposition (CVD) of silicon-containing films on silicon wafers at very low temperatures. Ultrahigh purity hexachlorodisilane is mainly used in the manufacture of next generation memory chips with the highest storage densities.
SIRIDION® TCS for optical fibers
Siridion® ultrahigh purity silicon tetrachloride is the key feedstock in optical fiber production. It is also used in the manufacture of polycrystalline silicon for the semiconductor and photovoltaics industries, and in the production of synthetic fused quartz glass.
VESTAKEEP® for ESD protection
Small electronic devices require narrower semiconductor fabrication. They need to occupy smaller spaces and perform better. But this leads to a critical challenge in processing: damage from electrostatic discharges (ESDs). Use our VESTAKEEP ® PEEK portfolio for ESD shielding.
How our products work
In the semiconductor industry, PERTRONIC® hydrogen peroxide plays an integral role in the integrated circuit manufacturing process. In the front-end-of-line, it is primarily used as an oxidizing agent in critical wafer cleaning and surface conditioning steps in transistor formation, copper/ULK dual-damascene formation, and post-CMP cleaning applications. In the back-end-of-line, hydrogen peroxide is used as an oxidizer in cleaning and surface conditioning applications related to 2.5D and 3D packaging applications, and as an etchant in the production of printed circuit boards.
Another product for the semiconductor industry is ultrahigh purity hexachlorodisilane that can be used in the manufacture of next generation memory chips. Silicon tetrachloride also plays a huge role in the manufacture of polycrystalline silicon for the semiconductor industry. In addition, Evonik offers a product for the surfaces of semiconductor chips. When vaporized and thermally decomposed upon the surfaces of semiconductor chips, ethyl silicate forms electrically insulating layers of silica glass which are necessary in the fabrication of integrated circuits.
Light-emitting diodes (LED) and fluorescent lamps are currently considered the top choice for lighting – especially given sustainability considerations. Fumed aluminum oxide (AEROXIDE®) and fumed silica (AEROSIL®) from Evonik really come into their own here, as strong binding agents or substrates in fluorescent lamps. You benefit in the production of premium illuminants: The specialized products offer you functions that are very difficult to achieve with other substances.
For example, AEROXIDE® particles work extremely effectively as binding agents in the phosphorus layer of fluorescent lamps, preventing mercury from penetrating the protective layer of the glass tubes, where it can impair the illumination quality. An effective mercury barrier layer thus increases the life span of fluorescent lamps, while also reducing energy costs.
Cable filling based on VESTOPLAST® offers excellent waterproofing properties along with a very good flexibility at low temperatures. VESTOPLAST® can modify cable jellies and thus help to prevent the cables from mechanical stress. Moreover, the environmentally neutral compositions are plasticizer- and VOC-free, strongly hydrophobic and resistant to chemicals and microorganisms. The formulations provide high dielectric breakdown voltage but do not attack plastic casings or cable sheathings. POLYVEST® is inert towards metals and alloys.
Epoxy is well-suited for electronics because of its temperature resistance and high strength. Our Ancamine®, Dicyanex®, Imicure® and Curezol products find their applications particularly in battery sealants, magnet bonding and electronics manufacture.
