  • Enhanced Polyisocyanurate Foams for Metal Faced Panels (.pdf)
    as the difference obtained in. terms of mechanical properties and k-factor. This paper describes the range of properties achievable with the VORATHERMTM family of isocyanurate-modified. polyurethane, showcasing reaction-to-fire and resistance-to-fire, mechanical and thermal insulation properties, as well
  • The Challange of Making Foam Stick (.pdf)
    systems, including the. chemical composition and mechanical properties of the foam(s) and all other substrates. that will be bonded ­ which could be anything from glass, plastic, metal or painted. surfaces to human skin. Of course, the adhesive system must be designed to meet the. particular
  • Glossary of Tems for Technical Foams
    the time required to obtain a given property deterioration. Usually charting mechanical property (tensile, tear, and/or elongation) loss over time. Abrasion Resistance. The fundamental ability of a material to withstand surface rubbing, erosion, or scraping. Generally, polyurethane foams display high
  • Characterizing Foam Hinged Lid Containers using DMA Testing (.pdf)
    . Rodriquez-Lorente, J.A. De Saja,. Dynamic mechanical properties of polyolefin foams studied by. Another part of the tan-delta curve that's important is the. DMA techniques, Polymer Engineering and Science, Vol. 37, No. 6, pages 959-965, 1997. slope and baseline (temperature) intercept. 2. Netzsch. Bulletin
  • Start here when simulating rubber and foams
    Little-known features in FEA software convert test data into inputs for simulating hyperelastic materials. Engineers at Applied Concepts, Medina, Minn., used Algor's Mechanical Event Simulation software to find stresses over time, along with residual stresses, in an automotive tire and wheel during
  • Next breakthrough material for military use could be carbon foam
    The Army Space and Missile Defense Command, Huntsville, Ala., recently recruited Touchstone Research Laboratory Ltd., Triadelphia, W.V., to continue development of its carbon-foam technology. CFOAM's combination of mechanical and thermal properties, along with its ability to accept surface coatings
  • Structural Foam
    . A high percentage of physical, mechanical, and electrical properties is maintained at elevated temperatures, within limits defined by the heat-deflection temperatures. The strength and stiffness of PSU and PES are virtually unaffected up to their glass-transition temperature. For example, the flexural
  • Prediction of Polyolefin Foamability
    Many different polyolefinic foams and effectively nonfoamable polyolefinic resins were studied by ASTM. D-4440, "Standard Test Method for Plastics: Dynamic Mechanical Properties Melt Rheology" techniques [1]. The sensitivity of this test method to chain branching of the polymeric molecule
