One of our bestsellers – through rapid prototyping, our team designs FIP gaskets that reduce the amount and the size of screw holes to achieve smaller overall packaging. In addition, our FIP can be placed on PCB traces as thin as 0.5mm, creating more space for board components.
Filled with Nickel/Graphite, Ag/Cu, Ag/Al, Ag/Ni or other conductive particles, providing excellent electrical conductivity.
Unique conductive gasketing materials for specialty applications:
Silicone and fluorosilicone Form-in-Place gaskets designed for protection up to an IP68 rating.
Can accurately place beads as small as 0.25 mm high. Through vigorous testing and rapid prototyping, we work with customers to overcome any accuracy challenge.
Our shielding solutions are consistently tested with outstanding results.
Let’s get down to the details.
ISO 9001 and AS 9100 Certified. ITAR Registered.
Cybersecurity Maturity Model Certification (CMMC) / SP NIST 800-171 Compliant. Learn More →

As electronic systems shrink and grow more power-dense, engineers must manage EMI, heat, and environmental protection within the same enclosure. Relying on multiple single-function materials increases complexity, assembly time, and space usage.
As electronic systems grow smaller and face harsher conditions, the demand for durable, chemically resistant gaskets continues to rise. Fluorosilicone-based Form-In-Place (FIP) gaskets meet this challenge with exceptional chemical and thermal performance, making them ideal for mission-critical applications.
Aerospace technology demands exceptional performance, reliability, and safety. As the industry faces increasing challenges, materials must evolve to meet these needs.

Here are a few commonly asked engineering and application questions about FIP gaskets and fluorosilicone materials:
A form‑in‑place gasket is a liquid elastomer dispensed directly onto a component’s surface—then cured into a precise seal—creating both environmental and EMI protection without manual gasket placement.
Fluorosilicone combines silicone’s wide temperature range with enhanced fuel, oil, and solvent resistance, making it ideal for aerospace, satellite, and harsh-environment applications.
It offers superior chemical resistance (e.g., JP‑10 jet fuel, solvents, salt fog), meets NASA outgassing standards, and cures into durable, machine‑dispensed seals with minimal waste.
Yes. By mixing conductive fillers—such as silver, nickel, graphite, or copper—into the base material, FIP gaskets can achieve over 100 dB EMI shielding across 200 MHz to 12 GHz.
Precision robotics (jet valves or XYZ dispensing) deposit a bead along the sealing groove. Then they’re cured—by heat, moisture, or UV—directly on the part, eliminating the need for dies or manual installation.
