The technology of urethane foam originated in Germany in the late ’s and Prof. Otto Bayer and his co−workers first developed rigid polyurethane foams based on polyester based polyol and toluene diisocyanate in the laboratories of the German I.G.

Plastics are increasingly a preferred material choice in designing and developing complex, consumer products, such as automobiles, because they are mouldable, lightweight, and are often perceived to be highly recyclable materials. However, actually recycling the heterogeneous plastics used in such durable items is challenging, and presents very different scenarios to how simple products, such Cited by:

Abstract The federal Bureau of Mines, in cooperation with Ford Motor Company, investigated the recovery of polyurethane foam and other assorted plastics from the nonmagnetic reject of automobile shredders.

Preliminary studies were conducted on a hulk augmented with additional foam and assorted plastics. Additional Physical Format: Online version: Recovering polyurethane foam and other plastics from auto-shredder reject (OCoLC) Material Type.

Polyurethane foam shredder PE Foam Shredder Cum Chipper Machine For Polyurethane Foam Waste Shredding and Recycling. When recovered, the polyols can be used as effective fuels, and the intermediates can be re-used to produce other polyurethane components.

This method uses a heated, oxygen-free environment to break down polyurethane and plastics into gases, oils and solids. Material recovery by hydrolysis was applied to PU foam waste from junk cars Cited by: The purpose of the glycolysis of flexible polyurethane foams is to recover the polyol.

In the process, three phases are obtained: an upper phase which contains the polyol, a bottom phase which has. Technologies for Recycling Shredder Residue. RECOVERING POLYURETHANE FOAM AND OTHER PLASTICS FROM AUTO-SHREDDER REJECT.

Polyurethane Recycling and Recovery Page 2 of 6 Polyurethane Recycling Processes Polyurethane is recycled in two primary ways: mechanical recycling, in which the material is reused in its polymer form, and chemical recycling that takes the material back to its various chemical constituents.

Mechanical Recycling Re-bonding. This book imparts a sound knowledge of flexible and viscoelastic polyurethane foams from their chemistry to calculations and formulating methodology for quality production.

The author presents very valuable detailed information on foam manufacturing based on more than 40 years hands-on experience in the local and international situations/5(3). The thermal degradation of plastics, either by hydrolysis or pyrolysis to chemicals or by incineration for energy recovery, is open to the same criticisms as that of any other structural material, in that one should, if possible, retain them in their most useful state, in this case as structural by: Polyurethane Recycling Processes Key Opportunities to Expand Polyurethane Recycling and Recovery For the Consumer Recycled Plastics and Polyurethane Database Resources and Links.
