Phenylene Oxide Based Resins

With the exception of NORYL phenylene oxide-based resin most engineering foams are reinforced. Loadings range from 4 to 40% (4). Thermoplastic resins molded in the form of structural foams include die following (5) ... [Pg.223]

Plastics can be divided according to their character into amorphous and crystalline. Crystallization is never complete and the so-called crystalline polymers are virtually semicrystalline ones. Examples of amorphous plastics are polystyrene, acrylonitrile-butadiene—styrene copolymers, styrene—acrylonitrile copolymers, polymethylmethacrylate, poly(vinyl chloride), cellulose acetates, phenylene oxide-based resins, polycarbonates, etc. Amorphous polymers are characterized by their glass transition temperature, semicrystalline polymers by both melting and glass transition temperatures. [Pg.3724]

Phenylene oxide-based resins (Noryl ) epoxy, polyisocyanate, polyvinyl butyral, nitrile rubber, neoprene rubber, polyurethane rubber, polyvinyUdene chloride, and acrylic. Polyethylene-nitrile rubber, polyisobutylene rubber, flexible epoxy, nitrile-phenolic, and water-based (emulsion) adhesives. Polystyrene for these foams (expanded polystyrene (EPS)), aromatic solvent adhesives (e.g., toluol) can cause collapse of the foam cell walls. For this reason, it is advisable to use either 100% solids adhesives or water-based adhesives based on SBR or polyvinyl acetate. Specific adhesives recommended include urea-formaldehyde, epoxy, polyester-isocyanate, polyvinyl acetate, vinyl chloride-vinyl acetate copolymer, and reclaim rubber. Polystyrene foam can be bonded satisfactorily with any of the following general adhesive types ... [Pg.152]

This material may be solvent cemented to itself or to certain dissimilar plastics, using a number of commercially available solvents, solvent mixtures, and solvent solutions containing 1-7% of the resin. The addition of 5-20% of the resin will reduce the evaporation rate and fill minor imperfections on the surface of the bonded joints. Recommended solvents are shown in Table 9.9. The solvents and solvent combinations shown for phenylene-oxide-based resins to themselves are especially designed to control the evaporation rate. ° ... [Pg.223]

It has outstanding long-term resistance to creep at temperatures up to 150°C. In this respect it is superior to polysuUbne, phenylene oxide-based resins, or polycarbonate. It is also capable of being used continuously under load at temperatures of up to about 180°C and in some low-stress applications to 200°C. A constant stress of 3000 psi at 20°C for 3 years produces a strain of 1 percent, whereas a stress of 6500 psi results in only 2.6 percent over the same time period. [Pg.428]
