What is foam rubber? Mr Beam explain it

What is foam rubber? We answer you in detail in this Materialguide. Regardless of whether slate, felt or acrylic. We deliver everything worth knowing about your favorite materials to the laser.

Foam rubber is an elastic foam With numerous applications. Foam rubber is of closed-porous structure and is made out Natural rubber, chloroprene or other synthetic rubber. The material Among other things, for sealing purposes and used as insulating clothing material. Likewise, the material is a popular craft. The Laser cutter allows a particularly precise and gentle processing and engraving of the foam rubber.

The material at a glance: What is foam rubber?

Moos rubber represents a material of high pressure elasticity as well as an outstanding restoring capacity. It is a largely closed-porous foam counted to the family of pore rubbers. Foam rubber Can be made from natural rubber as well as synthetic rubber. The application possibilities are manifold and range from use as sealing material to use as insulation material (such as immersion atmospheres).

Optically, foam rubber is very reminiscent of cell rubber, in contrast to this but a mix tailed driven material. In the foam rubber, the material properties of the used raw materials meet the special material structure. Inside this cell structure show the essential differences to the cell rubber. The mold vulcanized foam rubber can be manufactured with both compressed and closed surface.

Production: How does foam rubber arise?

The production of the foam rubber takes place under Addition of driving gases. The material may be made of chloroprene, natural rubber or NBR (acrylonitrile-butadiene rubber). Likewise, comparable synthesized rubbers are used, including CR, SBR, EPDM, HNBR, VMQ and FPM.

In the context of the production, a mixture of elastomers is brought under propellant addition to the desired structure. In this way, the desired Spongey surface texture. Vulcanization encourages different crosslinking processes. These are responsible for the foam rubber characterizing elastic and sponge-like properties. This structure is favored by the use of propellants.

The production can be done in two different methods. It is to be distinguished to distinguish between molded and extruded foam rubber components. The extruded foam rubber is characterized in the preparation of This out that the rubber compound is pressed by a mouthpiece. Its shape is crucial for the subsequent contours of the component. The molded foam rubber is brought into the desired, special form by using special metal molds.

What qualities has foam rubber?

The question, "What is foam rubber?" In addition to the starting materials, in particular on its properties refers. The characterizing technical property of any type of this material is its high pressure elasticity. This applies to a particularly high restoration capacity of the material. Profiles from this fabric are already attracted with only slight pressure to all surrounding surfaces. In this way, the material has particularly high sealing properties. The softness of the foam rubber can be consciously influenced by special mixtures and changes in the density (specific gravity) and direct it in the right direction.

The material forms a closed outer skin in the production. This makes the material resistant to most types of mechanical stresses. As well, Is foam rubber resistant to moisture and abrasion. It should be noted, however, that the material is due to damage to this outer skin danger to suck in with water. In this case, damage to the material threatens.

The fabric typically has a density of about 150 to 1000 kilograms per square meter. Here, material densities of 300 to 750 square meters are widely used and finds the most common application.

In addition to the printhead and high sealing properties, the material further has the following characteristic properties:

  • Abrasion resistance (due to the closed outer skin of the foam rubber)
  • High temperature resistance (depending on the mixture, especially at EPDM)
  • High aging resistance (especially at EPDM)
  • Flexible usage and processing properties
  • High damping properties
  • High compressibility
  • In certain variants, high flame and oil resistance

Use and applications of The material

the Soft and printhead structure With its closed surface, the fabric makes a popular material in several fields of application. Popular is the production of molded parts and profiles that can be easily varying with regard to properties such as elasticity, surface finish and softness. A Typical application for foam rubber is the sound insulation. Likewise, the material is used as a seal. Likewise, foam rubber is used for the elastic storage of various objects, including product packaging, housing seals and anti-slip mats.

In everyday life, the material is particularly popular as a carpet stopper or as a base. Even as impact protection, the substance is particularly well suited due to its printhead. Since it is outstanding Thermal insulation properties has, the use is common as cold protection. Cold protection suits for water sports often consist of this material. In this context, the substance is known under the brand name neoprene. This material variant is a fabric made of synthetic rubber made of chloroprene-based. Neoprene is also laminated for reinforcement on both sides with textile fabric (mostly nylon or Lycra). This material completes the surface and makes it less sensitive to damage.

For certain applications, different main groups of the material are used which depending on their properties to distinguish are. Natural rubber shows about a particularly high elasticity and a good refrigeration behavior. Chloroprene rubber (CR) has a particularly high weather and aging resistance and is also flammable. SBR (styrene-butadiene rubber) convinces with good mechanical properties as well as good heat and aging resistance. Acrylonitrile butadiene rubber has a special gasoline resistance and is also resistant to mineral oils and fats. Ethylene-propylene-diene rubber (EPDM) is a material with high heat and aging resistance, which is also resistant to ozone and other chemicals.

Craft properties: Can be crafted well with the material?

Moos rubber has one Long tradition as a craft starting material. From the material, a wide variety of objects can be crafted, from jewelry to decorative objects to toys. Also in the production of stamps, the material plays an outstanding role. Thanks to the good machining properties, the substance is also suitable for Children for crafting. For example, they can form figures or animals.

Due to the waterproof and Weather-resistant properties, craft objects from this material are also suitable for the garden or other outdoor areas, such as the House entrance.

If the procedure is correct, the fabric can also be glued well. It should be noted that the hot glue gun is only partially suitable because even thin materials can be easily burned with too hot glue gun. Remedy creates a double-sided tape here. Such The material can be attached to paper or other materials especially well.

How can foam rubber be painted well?

Paint this substance should be noted that not everything is liable well on this material. Straight hobbyists always find that Some pens on the material are not adhesive. Even after long phases of drying, many colors blur on this material. Regular felt-tip pins are hardly suitable as the color on the fabric is not resistant. For this reason, it requires a waterproof pen. Permanent markers are an alternative. Moreover, there are also Specialized foam rubber markers. These pens are commercially available under designations such as Foam Markers.

Processing with the laser cutter: foam rubber blanks and engravings

The material can be excellently with one laser machine to edit. The laser cutter ensures a gentle and contactless machining. The fabric is not warped or squeezed here. Blanks and engravings are therefore with Particularly high precision possible. Even more complex or elaborate blanks are hereby implementable.

Since this material is a print-sensitive material, the laser is particularly suitable for its machining. Since no pressure is exerted on the material during the laser cutting process, the pressure sensitivity of the foam rubber does not improve.

During the cutting process, it comes first to one Strong heating of the foam rubber through the laser beam. At the cutting point, the material is heated so much that the heat is dissipated at the same moment in the form of smoke. There is no damage to the surrounding material that is not cut. The result is a particularly clean and precise cut edge.
