Type & Form
   Foam Type       
   Your choices are...         
   Closed Cellular       Foams 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 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. 
   Rigid       Rigid foams have a matrix with very little or no flexibility.  
   Syntactic       Syntactic foams consist of rigid microspheres or glass micro-balloons held together by a plastic or resin matrix.

   Form / Shape:       
   Your choices are...         
   Casting Resin       Casting resins are plastic or elastomer compounds used to cast parts, molds or form a structure in place. They are available in the form of spray foams, "froth-packs", and A + B pourable foams. Casting resins usually consist of two part (A+B) systems that are cast into open molds or forms. A multi-component system typically consists of two separate components (A + B) where A is the resin and B is the catalyst or hardener.  The user or fabricator mixes the components to initiate the curing process.  
   Fabricated Shapes       Foam products are available fabricated into finished shapes or parts using molding, casting, extrusion, pultrusion, machining, thermal forming, plastic welding, blow molding, rapid prototyping techniques, grinding and/or other specialized processes. The exact dimensions and tolerances of the finished molded or cast parts are typically made-to-print based on the OEMs requirements and the supplier in-house capabilities. 
   Foam Spray       Foam is in the form of a sprayable liquid.  Spray foams are commonly used in construction insulation applications. 
   Molding Resin       Plastics or elastomers are suited for fabricating parts by injection molding, compression molding, blow molding or film extrusion, reaction injection molding (RIM), resin transfer molding (RTM), or molded stock shapes.   
   Board / Block       Plastics or elastomers are in the form of a sheet, strip, plate or slab shape. 
   Film / Sheet       Foam or core materials are in the form of a film sheet. 
   Rod / Bar Stock       Plastics or elastomers are in the form of a rod or bar shape. 
   Other       Other proprietary or unlisted forms.

   Thermoset / Crosslinked?       Thermoset plastics and thermoset resins are crosslinked polymeric resins cured using heat or heat and pressure. Cured thermoset resins generally have higher resistance to heat compared to thermoplastics, but melting cannot reprocess them. 
   Search Logic:      "Required" and "Must Not Have" criteria limit returned matches as specified. Products with optional attributes will be returned for either choice.
   Thermoplastic?       Thermoplastics can be repeatably softened by heat and then hardened, or set by cooling, which allows parts to be injection molded and scrap to be reprocessed.

Applications
   Applications       
   Your choices are...         
   Acoustics / Sound Proofing       Sound proofing or acoustic insulation material is used to form a barrier or isolator between components and sources of noise or vibration.  Also, foam material products used for diffusing sound without causing a large degree of attenuation. 
   Buoyancy       Foam products are designed or suitable for buoyancy applications. Typically, water resistant or waterproof closed cell foams are used for buoyancy applications.  
   EMI / RFI Shielding       Foam products are polymers or elastomers designed to provide shielding from electromagnetic interference (EMI) or radio frequency interference (RFI). Usually, these foams contain a ferromagnetic or conductive filler. 
   Impact / Energy Absorption       Foam products are designed to absorb mechanical energy to protect components, structures, and products from severe impacts, explosions, or other dynamic releases of kinetic energy.  
   Filtration       Open celled foams are suitable for filtration applications. These products must be resistant to the fluid, gas or media passing through the foam filter. The pore size (ppi) determines the size of the particles that can be filtered out, as well as the flow rate through the filter. 
   Static / ESD Control       Foam products control static or electrostatic discharge (ESD) to prevent damage to sensitive electronics. Usually, these products contain a conductive filler that dissipates the static charge to the ground 
   Shock / Vibration Dampening       Foam products are suitable for shock or vibration dampening applications. Foam's high internal porosity and viscoelastic nature results in good vibration dampening characteristics. 
   Structural / Composites       Foam products are designed for structural applications such as constructing composite foam cored laminates, column bearing blocks, sandwich panels or other foam cored structures.  
   Other       Other unlisted, proprietary, or specialty features.
