Two types of asphalt were used blown asphalt and emulsified asphalt. Blown asphalt is asphalt stock that has been heated at temperatures from 200°-300°C and had air blown through it. The process is one of dehydrogenation and polymerization, resulting in a product that is thermally more stable. We used a blown asphalt provided by the Exxon Corp. because it most closely resembles Mexphalt R 90/40 (Shell Oil Co.), the blown asphalt used most in Europe. Mexphalt R 90/40 is not available in the U.S., but differs chiefly in being somewhat softer than the asphalt from the Exxon Corp.

The extrusion aid must easily coat the resin yet be readily removable from the extrudate. It should also not leave a residue which could alter the color of the product. The volatilization temperature of the lubricant should be lower than the sintering temperature of the polymer. The other requirements of lubricants include high purity, low odor, low polar components, high auto-ignition temperature, low surface tension, and low skin irritation. Common lubricants are synthetic isoparaffmic hydrocarbons available in a wide boiling range. Some of the commercial lubricants include Isopar solvents (available from Exxon Corp.), mineral spirits, and VM P Naphtha (available from Shell Corp.).
