SABIC gives several leading materials for 5G infrastructure. Its NORYL™ SA9000 grade is a modified low-molecular-weight, bi-functional PPE oligomer. This material works in high-performance multilayer copper-clad laminates (CCLs) for 5G base stations and high-speed AI server PCBs. SABIC also provides ULTEM™ resins for cooling fans, liquid cooling connections, signal connectors, and on-board optics. Its LNP™ FARADEX™ compounds give EMI shielding, while LNP™ STAT-KON™ compounds deliver anti-static performance. LNP™ ELCRES™ copolymers cover busbars in data centers.
Celanese has a strong position in liquid crystal polymer (LCP) supply. The company bought DuPont's LCP business and now controls about 30% of the global market. Its yearly capacity reaches around 22,000 tons. This scale matters because LCP films fit high-speed, high-frequency electronics like 5G mobile antennas.
DuPont makes its engineering plastics for high signal integrity in 5G assemblies. The portfolio includes high-performance PEEK and custom polyimides. These materials give thermal reliability under demanding operating conditions. They also support compact, ruggedized network equipment. DuPont works with network infrastructure leaders, which strengthens its technical leadership.

These materials meet the strict requirements of 5G components. BASF backs its products with broad technical support and a global presence. Its market-driven R&D aligns innovation with customer needs.
3M contributes through additives and fillers rather than base resins alone. Its Glass Bubbles cut part weight by 15% to 40% in 5G antennas and assemblies. These hollow microspheres also reduce resin costs. The Boron Nitride Cooling Fillers (BNCFs) improve thermal performance and signal transmission. They feature low Dk and Df to maintain 5G signal strength. 3M thermally conductive tapes bond stainless steel and low-surface-energy substrates. These tapes suit active antennas, small cells, remote radio units, and mobile edge server hardware. Conductive gaskets replace screws in applications from small cells to repeaters. This change cuts assembly time and cost.
Which company provides engineering plastics for 5G? The answer depends on the specific application. SABIC and Celanese lead in high-frequency resins. DuPont excels in signal integrity and thermal reliability. BASF and 3M bring specialized additives and low-loss materials. Polysesle covers electronics and electrical needs with dedicated support. Piedmont Plastics and Juyuan round out the supply chain for semiconductor and telecom parts.

Liquid crystal polymer (LCP) films work well in high-speed, high-frequency electronics. They keep stable dielectric properties across a wide frequency range. LCP has a dielectric constant (Dk) of 2.9–3.2 and a dielectric loss tangent (Df) below 0.004 from 1 to 110 GHz. At 28 GHz, Df falls to 0.002 or lower. These numbers help 5G mobile antennas and wearable circuits, where signal loss must stay very low. LCP also takes in less than 0.02% water, so its Dk stays the same after 1,000 hours at 85°C and 85% relative humidity. Its thermal stability goes above 280°C, which survives reflow soldering.
Material | Dk | Df | Water Absorption |
|---|---|---|---|
LCP | ~3.0 | 0.002 (28 GHz) | < 0.02% |
Polyimide (PI) | ~3.5 | ~0.008 | 1.5–2.5% |
FR-4 glass epoxy | ~4.4 | ~0.02 | — |
Polyphenylene sulfide (PPS) gives a dielectric constant of 3.0–3.5 at 1 MHz and a dissipation factor below 0.001. Its vertical thermal conductivity is over 2 W/m·K, and its breakdown voltage is above 50 kV/mm. These traits make PPS helpful for 5G infrastructure that needs both insulation and heat dissipation. Polyetherimide (PEI) gives tensile strength of 105–110 MPa at 23°C and keeps over 70% of that strength at 180°C. PEI also gives up to 88% infrared transparency in the 850–1550 nm range, which fits optical modules.
Fluoropolymers such as PTFE serve cable insulation and coatings in 5G systems. PTFE has a dielectric constant near 2.1 and a loss tangent of about 0.0002 to 0.0004. At 10 GHz, a 6-inch PTFE trace may lose only about 0.1 dB, while FR-4 loses over 1 dB. PTFE also resists acids, solvents, and UV radiation. Its breakdown voltage is above 60 kV/mm, which supports high-power RF use.
Polycarbonate (PC) keeps mechanical properties up to 135°C and gives high impact resistance, UV stability, and optical clarity. Manufacturers use PC for protective enclosures, radomes, and semiconductor device casings. PBT with 20–50 wt% glass fiber reaches a tensile modulus of 8–12 GPa and a heat deflection temperature of 210–230°C. Vinyl aromatic additives lower PBT's dielectric constant to 3.2–3.8 and dissipation factor to 0.008–0.015 at 1 MHz. ASA combines acrylic weather resistance with ABS toughness. It keeps color stability and mechanical integrity under long sunlight, which fits outdoor 5G equipment housings. Juyuan supplies PC, PBT, LCP, ASA, and PPS for base stations, antennas, and optical modules.
Signal quality guides which materials engineers pick for 5G antennas and RF front-end parts. A material's dielectric constant (Dk) and loss tangent (Df) show how much signal energy turns into heat. Regular polyimide (PI) has a Dk of 3.0–4.0 and a Df near 0.02, so it does not work well for high-frequency 5G signals. Liquid crystal polyester (LCP) has a Dk around 2.9 and stays steady across mmWave bands. Cyclo-olefin polymer (COP) reaches a Df of 7.5 × 10⁻⁴ at 40 GHz, which means over ten times less loss than regular PI. These low-loss materials fit sub-6 GHz and mmWave antenna modules, where every small bit of a decibel counts.
For 5G antenna covers (radomes), materials must let radio waves pass through while fighting weather, impact, and flame. Mixing flame retardancy with low dielectric performance has long been a hard task for engineers. RF cavity filters and waveguide antennas do well with low-dielectric engineering plastics like modified PPE grades. These grades give high heat resistance, great plating features, low thermal expansion, and dimensional stability close to metal. This mix allows weight reduction without losing electrical performance.
5G base stations and optical modules make a lot of heat while running. Materials must carry or release that heat while keeping their structure strong. Polysesle Electronic and Electrical Materials offer superior thermal management, electrical insulation, and mechanical strength. These traits support flexible circuits, connectors, and protective casings in smart wearables, laptops, and mobile phones. The materials help devices run cooler and last longer under nonstop load.
Mechanical strength counts for base station housings, antenna brackets, and optical module frames. These parts face wind loads, vibration, and thermal cycling. A material with high tensile strength and dimensional stability fights warping and cracking over years of use. Polysesle materials give the needed toughness while keeping designs thin and light. This balance lets manufacturers build sleek 5G equipment without giving up durability or heat dissipation.
