- Product Highlights
ULTEM 3473 resin is 40% lighter than aluminum and a potential alternative for these RF filters thanks to its low CTE, Surface Mount Technology (SMT) process compatibility and excellent surface metallization performance.
Integrated Antenna Filter Units
ULTEM 3473 resin can also support the design of new integrated antenna filter units (AFUs), which cannot be achieved with metal. Using injection molding, the dipole antenna matrix and RF cavity filter body can be produced as one component. This approach simplifies production and may lead to cost reductions and additional weight savings.
Ultem 3473 Resin is Compatible With SMT Technology
Thanks to improved Heat Deflection Temperature (HDT), ULTEM 3473 resin can withstand the 260°C peak temperatures in solder mount assembly.
Coefficient of Thermal Expansion (ISO 11359-2)
Cross flow improvement over glass filled PPS for improved dimensional stability
Improved Heat Deflection Temperature (ISO 75)
ULTEM 3473 resin has a HDT close to glass filled PPS
Potential For Metal Replacement Using Ultem™ Resin
ULTEM resins have excellent surface metallization performance and are compatible with mainstream plating processes. An excellent candidate for 5G networking components, ULTEM resins can also be considered for use in other industries where metal replacement is desired. ULTEM resins can be used in metalization processes like electroless plating, electro- plating and physical vapor deposition (PVD).
To address varying product and processing requirements, multiple ULTEM resin grades are available in the portfolio and can be considered for metal replacement. Each of these grades show an excellent adhesion to metal, low surface roughness and great resistance to blistering and delamination after exposure to thermal shocks and long periods of humidity.

- ᵍ Measurements made from Laboratory test Coupon. Actual shrinkage may vary outside of range due to differences in processing conditions, equipment, part geometry and tool design. It is recommended that mold shrinkage studies be performed with surrogate or legacy tooling prior to cutting tools for new molded article.
- ⁷ Injection Molding parameters are only mentioned as general guidelines. These may not apply or may need adjustment in specific situations such as low shot sizes, large part molding, thin wall molding and gas-assist molding.
