Closed Cell Sponge Rubber
Gaskets
Closed cell
sponge rubber, technically referred to as expanded
rubber, consists of
cells that are like individual balloons holding gas
and not allowing moisture to pass through as long as
the cell wall has not burst. The raw compound is
mixed on the same type of equipment used to mix
solid rubber compounds, but a chemical blowing agent
is also added. Under the heat and pressure of a
pre-cure or pre-forming process, this additive
decomposes and mixes with the rubber compound and
generates nitrogen gas. As this reaction is
occurring, the mixed batch is placed into an oven
and allowed to expand into a bun from 2" to 4"
thick. The material is then skived to
thicknesses from .062" and up.
Closed Cell sponge rubber
gaskets are utilized in variety of industries and
applications including, Automotive, Applicance,
Construction, Sports Equipment, Office Equimpment,
Electrical Enclosures, Heating/Air, Lighting and
more.

Poron®
Microcellular Urethane Foam Gaskets
PORON®
Microcellular Urethane foams offer a broad range of
design solutions for gasketing, sealing, vibration
and sound dampening and energy absorption. Low
compression set and low outgassing features make
these high performance foams ideal for applications
in communications, automotive, electronic, and other
industrial devices.
- Excellent compression
set resistance which enables durable, long-term
performance for gasketing, sealing, and
cushioning.
- Low-outgassing and non-fogging, containing
no plasticizers or residual chemicals to
contaminate the device. The material will not
become brittle and crumble and is non-corrosive
to metal.
- Inherently flame retardant without the use
of additives. Many of the materials meet
flammability requirements of UL HBF and MVSS
302.
- Engineered urethane formulations offering a
wide modulus range - 2-90 psi @ 25% deflection –
for more design versatility requirements.
- Good chemical resistance
- Easy to fabricate, die-cuts cleanly and
works with a broad range of adhesives
- Broad range of formulas and thicknesses from
0.012" to 0.500" (0.43mm to 12.7mm)

Silicone Sponge Gaskets
Silicone sponge has the
combined properties of resilience, high temperature
stability and general inertness unavailable in any
other elastomer. Silicones are generally unaffected
by extended exposure to temperatures from
-100°F
to 500°F,
and are also unaffected by aging and degradation
from sunlight and ozone.
Silicone sponge
materials are available with a wide range of
properties including products with low compression
set properties, UL94HB flame ratings*, thermal
conductivity, fluid and fuel resistant
fluorosilicone and general purpose silicones. We
regularly apply a variety of acrylic and silicone
polymer based adhesive backings and offer secoESD
surface coating,
.
