Parker Chomerics’ Cho-form
(Conductive) and ParPHorm (non-conductive) are two types of form-in-place
gasketing materials that are used in a variety of industries, including
electronics, automotive, and aerospace. These materials are able to conform to
complex shapes and create a watertight seal, making them ideal for applications
where traditional gaskets cannot be used.
Design Considerations
Typically we recommend a minimum gasket height of
0.8mm or 1mm with a maximum of roughly 1.6mm for a singular bead. Higher would
be possible with bead on bead.
To achieve a good quality gasket, we recommend
about 0.2-0.3mm space within the metal chassis, to allow for the bead to sit
nicely within the groove.
It is preferred for the metal work receiving the
gasket has a U-shaped groove as it may offer more longevity of the gasket bead.
While we can dispense/ facilitate a FIP Gasket on no groove metal work/ etched
metals we cannot assure the same level of longevity.
Benefits of Form In Place
Custom Design - The programmable machine allows for the production of gaskets in various shapes.
Watertight Seal - Cho-form and ParPHorm create a watertight seal that prevents leaks.
Conformable - Cho-form and ParPHorm can conform to complex shapes, making them ideal for applications where traditional gaskets may not suffice.
Durable - Cho-form and ParPHorm are durable materials that can withstand harsh environments.
