Reduce part weight through metal replacement

Integral EMI protection eliminates secondary coating processes

Consistent EMI shielding effectiveness up to 80 GHz

Increased design freedom with plastic material

Imagine being able to easily produce housings for automotive sensing systemsusing a material that incorporates EMI shielding properties into a ready-to-moldplastic compound... At RTP Company, we not only imagined them, we’ve madethem a reality.

Protecting the sensitive components of vehicle sensing systems from EMI “noise”is critical to their proper operation and reliability.

Increasing deployment of these systems has automotive designers and engineersseeking material solutions that allow them to creatively integrate them into vehicledesigns without increasing vehicle weight.

Injection moldable thermoplastics provide both design freedom and cost reduction.They offer engineers the ability to create complex parts, consolidate multiplecomponents, and can quickly be produced in high volume. This eliminates costlysecondary operations common in metal castings while significantly reducing partweight.

Incorporating conductive additives and metallic fibers imparts plastic compoundswith EMI shielding capabilities. These EMI characteristics can be “tuned” to meetthe design requirements of specific applications.

Unlike the difficult and labor intensive manufacturing processes associated withconductive coatings, EMI plastics provide an environmentally-friendly optionwhere shielding properties are integrated into the part. This will cost-effectivelymaximize design flexibility, production speed, reliability, damage tolerance,part-to-part consistency, corrosion resistance, and recyclability.

Additionally, secondary properties for thermal management, EMI absorption,impact resistance, and structural reinforcement can be incorporated into theplastic matrix during compounding – allowing finished parts to be produced in asingle-step injection molding manufacturing process.
