The primary use for this material is gasket fabrication. It also can be used for creating environmentally-friendly performance shoe insoles, and shock-absorbent material for mobile device cases. Additionally, Poron® can be used as a water retardant, spacer, motor mount, vibration isolator, EMI/RFI shield, sound dampener, and gap filler. According to the Rogers Corporation website, the following information is available about Poron®.
- ranges from extra soft to very firm, 4790 Series
- extra soft with a very low closure force, and4790 Supported Series
- extra soft, supported material with a very low closure force. For more information, refer to the Manufacturer website located in the Manufacturers section
- Rolls, sheets, finished spools
- Extra soft to Very Firm (range)
- 400 – 600 ft. (range)
- 20 - 54 in. (range, depending on product), if the material is needed in a narrower width, Rogers will slit rolls based on the customer’s request.
- .012 - 0.500 in. (range, depending on product)
- Black, gray
- 3 years (if not altered from as manufactured)
Additionally, products made with Poron®
have these highly reliable benefits:
- Excellent compression set resistance enabling durable, long-term performance for gasketing, sealing, and cushioning.
- Low outgassing and non-fogging, containing no plasticizers or residual chemicals to contaminate the device, so material will not become brittle and crumble. It is non-corrosive to metal.
- Inherently flame retardant without the use of additives. Many Poron® materials meet UL HBF and MVSS 302 requirements.
- Broad range of formulas including engineered formulations that offer good chemical resistance and work well with a wide range of adhesives.
may appear to look like a closed-cell foam, it is an open-cell foam, so it is not recommended for applications where the foam is needed to protect, for example, against moisture or debris. In those cases, a supported Poron®
might work better.
Poron® Fabrication and Processing
Most common method of processing Poron® is die cutting. For more information about methods used to process Poron®, refer to the following section.
Poron® Processing Methods
Die cutting - advantage is commonly throughput (allows many strikes per minute); disadvantages include setup labor and time, die acquisition and qualifying time (cost, wear, storage), difficulty with precision, difficulty with tolerance, and it can cause roll-over on edges (with thicker materials).
Waterjet cutting - advantages include minimal setup time, thick foam cutting (fairly fast with straight lines); disadvantages include the cost of equipment, possible water contamination, throughput (slower than other methods), and thin material or small features can be difficult to cut.
Computer controlled knife cutting - advantages include thin materials can cut well at high speeds with specialty machines; difficulty cutting thicker materials, blades can dull, pull, and distort softer materials, and it can be slower than other methods.
Laser cutting - advantages include that it works with the whole range of thicknesses of Poron®. However, this process works exceptionally well with thinner material and design files where precision is a necessity. Laser material processing allows the ability to produce scalable, accurate products using a non-contact method. No roll-over of the material edges is experienced with laser cutting. Complex pieces are easily cut with a cauterized and smooth edge quality. Parts drop out of the larger piece after cutting cleanly. Small parts work especially well with laser processing as it allows for tighter tolerance. For more information about Laser material processing, refer to the Laser processing section.
Laser Processing Advantages for Poron®
Laser processing is ideal for cutting or engraving Poron®, and works well with the whole range of thicknesses, 0.012 - 0.500 in. The following describes the different laser material processes that work best with with Poron®.
The polymer material absorbs light from the laser and converts it to heat. The heat causes material that is directly in the laser's path to vaporize (ablation). Laser cutting can be performed on all formats of Poron®
, but most commonly on sheets. Laser cutting with Poron®
is ideal for detailed design files requiring precision as shown in the Poron®
cutting photo shown. Because laser cutting is a non-contact method, the material does not move, and the edges remain flat when working with it.
The polymer material absorbs light from the laser and converts it to heat. The heat causes material that is directly in the laser's path to vaporize (ablation). Laser engraving can be performed on all formats and thicknesses of Poron®
, but most commonly on sheets. When engraving Poron®
, the removal of material leaves a brownish mark as shown in the engraving photo.
