FVMQ Rubber Diaphragm Seals Fluorosilicone Gaskets Molded
Introduction:
Hongum specializes in precision die cut and molded silicone rubber
gaskets and seals for applications and industries worldwide.
Silicone rubber is a high-performance elastomer with exceptional
resistance to temperature extremes. Silicone molded and die cut
gaskets remain functional within a temperature range of -67°F to
+400°F, intermittent to +450°F. The low temperature flexibility of
silicone is unmatched by any other elastomer. Silicone gaskets are
often chosen due to their excellent resistance to chemicals, water,
fire, fungal growth, ozone, heat and aging. Silicone has
outstanding tensile strength, elongation, tear strength, and
compression set. The versatility and long service life of silicone
make it ideal for a wide variety of applications.
Hongum provides precision die cut and molded fluorosilicone rubber
gaskets and seals. Similar to silicone, fluorosilicone (fluorinated
silicone rubber) is intended for applications where there is
contact with petroleum-based chemicals. However fluorosilicone can
withstand more extreme temperatures and has superior chemical
resistance properties to fuels, coolants and oils than standard
silicone.
The main products of rubber sealing gaskets are: silicone pads,
nitrile rubber pads, fluorine rubber pads, and other rubber pads.
Die Cut Silicone Gaskets
Hongum provides die cut silicone gaskets in a wide variety of
grades, thicknesses, and hardness. The standard thickness of
silicone rubber ranges from .010″ to 1″ thick. Silicone rubbers
hardness (durometer) typically spans from 30 to 80 durometer, Shore
A. We inventory a full spectrum of colors including red/orange,
black, gray, blue, white, and translucent. Silicone rubber gaskets
are available with or without acrylic or high temperature pressure
sensitive adhesive (PSA) backing.
Gasket Professional:
The sealing washer is affected by the material and process of the
threaded fasteners, and most of the supporting surfaces of the
fastened parts of the bolts will not be very large, thus reducing
the pressure to protect the surface. In order to prevent the
loosening of the connection pair, anti-loose sealing spring
washers, multi-tooth locking sealing washers, round nut stop
sealing washers and wave-shaped and conical elastic washers are
used. The gasket is mainly used to reduce the pressure. When some
parts are tightened with a large axial force, the gasket is easy to
be pressed into a dish shape. At this time, it can be solved by
changing the material and increasing the hardness.
The sealing effect of the sealing DSH spring washer is average, and
the important parts are used less or not as much as possible, and
the self-locking structure is adopted. For high-speed tightening
pneumatic sealing spring washers, it is better to use
surface-treated washers to improve its wear-reducing performance,
otherwise it is easy to burn out or open due to friction and heat,
and even damage the surface of the connected parts.
Gasket construction should not be used with respect to sheet
joints. According to the analysis, the spring sealing washer is
used less and less in the car. Due to the large and uniform locking
force, the connecting tooth shape in the tooth-shaped sealing
elastic gasket is used more in the automotive industry, while the
spaced tooth shape is less.
Key Selection Considerations for Gasket Materials
When choosing a gasket material, there are several factors to keep
in mind to ensure the one chosen is appropriate for the intended
application. Some of the key considerations are:
| Temperature: | what temperature range is it expected to withstand? |
| Pressure: | what pressure range is it expected to withstand? |
| Media: | what materials will it be exposed to? (e.g., are the process fluids
abrasive or corrosive?) |
| UV and ozone exposure: | will it be exposed to UV radiation and ozone? |
| Product standards: | is it subject to any industry-specific product requirements? (e.g.,
does it need EMI shielding properties?) |
| Industry standards: | is it subject to any other industry-specific standards? (e.g., does
it need to meet ASTM, UL, or Mil-spec requirements?)
