Foam Material




   Material       
   Your choices are...
 
      
 
   Polyester Foam
 
     Thermosetting resins or plastics based on the polyester (alkyd) system.  These materials should not be confused with thermoplastic polyesters or PET resins.  Also includes foam using a polyester polyol as a component of the polymer chemical system.

Esters are generally described only by their density. Pore sizes are more controllable than in ethers. Ester foams are used in packaging, gasketing, sound attenuation and filtration applications.
 
   Polyether Foam
 
     Foams that use polyether polyol as a component of the polymer chemical system. Ether foams are described by their density and compression ratings and are more resilient, available in more variations and are less expensive. Ether foams are used in furniture, bedding and many packaging applications.
 
   Polyethylene Foam
 
     Polyethylene is a closed cell, expanded, extruded flexible plastic foam. It is primarily used as a protective packaging material because of its predictable shock absorbing qualities. It is available in densities from 1.2 lbs./cu. ft. up to 6.0 lbs./cu. ft. The compression (firmness) of polyethylene foam is directly related to its density — the heavier the foam, the harder it is.

Polyethylene foam is available in roll or sheet / plank form. Due to the nature of the extrusion process that produces this material, the thickness of rolls and planks is very limited. In order to provide thickness greater than 2.0 inches, this material must be laminated. The resulting material can be up to three layers thick for a total of 6.0 inches for bulk foam. Fabrication using various adhesives across smaller areas can produce much thicker combinations.
 
   Polystyrene Foam
 
     EPS expanded polystyrene.
 
   Polyurethane Foam
 
     Polyurethane is an open cell chemically expanded product created by a rapid chemical reaction which produces a high volume of carbon dioxide gas as a byproduct. This gas creates bubbles within the matrix of the chains of polymers which become the cell walls. The gas escapes, leaving behind a skeleton of foam.

The quality and performance of these cell walls make up the physical characteristics that will, upon curing for at least 24 hours, determine the firmness and resiliency of the final product.
 
   Cross-linked PE Foam
 
     Cross-linked polyethylene foam is made by adding several additional ingredients to standard polyethylene foam to produce a finer (smaller) celled product. As a result, it has a smoother texture than standard polyethylene foam and offers some different shock absorbing parameters.

This material is made in thinner layers than standard polyethylene forma, using 0.5 inch increments instead of 2.0 inch increments. It is also heat laminated under carefully controlled conditions.

   Search Logic:      All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
   Type       
   Your choices are...
 
      
 
   Closed Cellular
 
     Foams that have pores or cells that are not interconnected and are sealed off to an external surface. Closed cellular foams are useful for buoyancy and floatation applications.
 
   Open Cellular
 
     Foams that have pores or cells that are interconnected and open to an external surface. Open-porosity foams are useful for filtration-type applications. Open cellular foams are not useful for floatation applications unless the surface is sealed or closed off.
 
   Flexible/Soft Foam
 
     Flexible or cushioning materials that can bend, flex or absorb an impact without cracking and delaminating.
 
   Rigid Foam
 
     Rigid foams have a matrix with little or no flexibility. 
 
   Reticular
 
     Reticular foams have a very open structure with a skeletal matrix consisting of an interconnecting network of thin material strands. Reticular foams can be envisioned as having a random three-dimensional mesh between pores.
 
   Syntactic
 
     Syntactic foams consist of rigid microspheres or glass micro-balloons held together by a plastic or resin matrix.

Capabilities




           
   Your choices are...
 
      
 
   Contour Cutting
 
     Contour cutting refers to the ability to machine foam and produce desired contours or patterns on the cutting surface.
 
   Convolutions
 
     Convolutions, egg-shaped patterns, are fabricated through a special cutting process.  First, a pattern of pressure points depresses the foam.  While depressed, the foam is cut.  The result is an egg-shaped contour pattern on the foam surface.
 
   Die Cutting
 
     Die cutters and die cutting machines convert web or sheet materials into shapes.
 
   Finished Product Assembly
 
     Products made of foam that are in themselves the finished product.
 
   Foam Felting
 
     Curing process where thick softer foam materials are compressed and cured in order to fabricate denser foam materials.
 
   Gluing or Foam Welding
 
     Fusion of layers by either gluing or welding processes.
 
   Heat Impressions
 
     Use of heat and pressure to form permanent impressions.
 
   Heat Seaming
 
     Use of heat and pressure to create seems.
 
   Hot Wire Cutting
 
     Cutting method, predominantly used with polystyrene foam, where heated wire is used to produce smooth straight cuts.
 
   Laminating
 
     Laminates are products made by bonding together two or more layers of material.
 
   Molding
 
     Use of one of a number of different molding techniques to produce foam shapes and products.
 
   Routing
 
     Routing machines have a revolving, high-speed vertical spindle and cutter for milling out the surface or edges of materials.
 
   Slitting
 
     Cutting wheels or other similar cutting methods used to fabricate fixed width foam rolls or sheets.
 
   Thermal Forming
 
     Using heat to reform bulk foam material into desired shapes.  A popular method for producing foam sheets.
 
   Water / Abrasive Jet Machining
 
     In abrasive machining, a jet of water and abrasive is directed at the material to be machined. The jet drags the abrasive through the material in a curved path and the resulting centrifugal forces on the particles pressing them against the work piece. The cutting action is a grinding process where the forces and motions are provided by water, rather than a solid grinding wheel. The result is a very small width of cut allowing for precise machining.
