Description

IsoClad® 933 laminates are nonwoven fiberglass-reinforced PTFE composite materials tailored for deployment as printed circuit board (PCB) substrates. The nonwoven reinforcement architecture imparts enhanced flexural capability, making these laminates ideally suited for applications requiring post-fabrication circuit bending—conformal or “wrap-around” antennas represent a prime use case for this attribute.


Unlike standard nonwoven fiberglass/PTFE alternatives, IsoClad series laminates incorporate longer randomly oriented fibers and leverage a proprietary manufacturing process to deliver superior dimensional stability and enhanced dielectric constant (Dk) uniformity, even when compared to competitive products with equivalent dielectric constant values.


With a dielectric constant (Er) of 2.33, IsoClad 933 laminates utilize a higher fiberglass-to-PTFE ratio to form a highly reinforced composite structure. This optimized formulation achieves improved dimensional stability alongside elevated mechanical strength, without compromising core electrical performance.
