  • Viscoelastic changes and cell opening of reacting polyurethane foams from soy oil
    Modulus develop- ment was also monitored for polyurethane foams from synthetic polyol voranol for comparative purposes. The samples were coated with plat- inum up to 50A thickness before viewing under the mi- croscope.
  • Bio-Based Polyols
    The polyurethane carpet backing may be used as a precoat, a laminate or foam coating . In an example, a polyurethane reaction product is made by mixing together in a blend tank, Voranol 9287A polyol , dipropylene glycol, tripropylene glycol, SoyOyl GC5N, Georgia Marble D70 and Dabco T-12. 4/25/03 Aldehydes and alcohols derived from seed oils are converted into polyols for use in polyurethanes.
  • Comparing the effect of carbon-based nanofillers on the physical properties of flexible polyurethane foams
    First, a fixed amount (0.5 phpp, approximately 0.3 wt% in the final foam) of the different carbon nanof- illers was added in the polyol ( Voranol 6150). In order to achieve a good dispersion, the mixtures were initially sonicated for 20 min using an... ...were cryo-fractured perpendicular to the foaming direction and the fracture surface was sputter- coated with gold/palladium.
  • Superabsorbent Polymers
    The fluidization with warm air occurs for approximately 30 minutes, and is stopped when the SAP powder... ...aluminum is used, Dow’s patent recommends producing a solution of aluminum sulfate, and coating the SAP powder... In particular, Dow uses its VORANOL ® propoxylated polyol at a concentration of 500 ppm in the saline solution.
