摘要： A process for the preparation of molded high strength composites comprising fibrous reinforcing material impregnated with a reaction injection molded polyisocyanurate resin. The process comprises first evacuating a mold containing the fibrous reinforcing material said mold equipped with means for accepting an overflow volume of the resin. The mold system is pressurized prior to gelation causing the overflow volume to be forced into a final volume. The molded composites have a high flexural moduli, good physical properties, low void content and smooth surface.

摘要： A female die part has an upwardly opening die cavity for receiving a male die plunger, a supporting surface around the cavity for a porous batt of fibrous reinforcing material overlying the cavity, and a first shearing edge defining the periphery of the opening for the cavity. Peripheral portions of the batt are clamped to the supporting surface, whereupon the die plunger presses portions of the batt into a mold formed between the male plunger and the sidewalls of the cavity to completely fill the mold. A cutter having a second shearing edge cooperates with the first shearing edge to shear peripheral portions of the batt from the portions overlying the die cavity. The shearing edges in cooperation with the die plunger seal the mold to enable injection of reactive chemicals that impregnate the porous batt within the mold.

摘要： Particle boards are currently prepared by treating the particles (e.g. wood chips) with a binder comprising an organic polyisocyanate and an internal release agent and then subjecting the treated particles to a forming process involving heat and pressure. While the resulting particle board will generally release well from the caul plates of the press after forming, due to the effect of the internal release agent, it has been found that the ease of release is enhanced by precoating the surfaces of the caul plates or platens which come into contact with the particle board with a layer of polytetrafluoroethylene which layer optionally contains an internal release agent.

Preferably, the elastomer component has a melt tan delta between about 0.7 and about 8, as measured by parallel plate rheometer at 0.1 rad/sec, 190° C., and 15 percent strain; and the ratio of the “melt tan delta of the elastomer component” to the “melt tan delta of the propylene component” is from 0.5 to 4. The invention also provides for method of making such compositions, and to low gloss articles prepared from the same. The inventive compositions are particularly suitable for fabricating thermoformed sheeting with reduced gloss.
