What is a form-in-place (FIP) gasket?

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.

Why use fluorosilicone in FIP gaskets?

Fluorosilicone combines silicone’s wide temperature range with enhanced fuel, oil, and solvent resistance, making it ideal for aerospace, satellite, and harsh-environment applications.

What are the advantages of fluorosilicone FIP?

It offers superior chemical resistance—such as to JP-10 jet fuel, solvents, and salt fog—meets NASA outgassing standards, and cures into durable, machine-dispensed seals with minimal material waste.

Can FIP gaskets be conductive for EMI shielding?

Yes. Conductive fillers like silver, nickel, graphite, or copper can be added to the base material to create EMI shielding FIP gaskets with performance over 100 dB from 200 MHz to 12 GHz.

How are FIP gaskets applied and cured?

Precision robotics dispense a bead of elastomer directly onto the sealing surface, which is then cured—via heat, moisture, or UV—without requiring manual placement or dies.

EMI & ENVIRONMENTAL SHIELDING

Form-In-Place (FIP) Gaskets

As versatile as they come.

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.

Technical FAQ

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.
