Diallyl Phthalate DAP

DAP is the most commonly used of the allylic esters, which are a branch of the polyester family. [Pg.54]

These thermoset products are typically selected for outstanding dimensional stability, ease of moulding and excellent electrical properties. [Pg.54]

DAP can be bonded with most engineering adhesives and good strengths [3] are achieved for many different adhesive technologies (Table 3.1). [Pg.54]

The cyanoacrylates (without primer) showed excellent results in these trials (Table 3.1) but DAP are often used in moist environments and so care must be taken if selecting a cyanoacrylate as a structural adhesive. [Pg.54]

Notes Substrate failure All shear strengths are given as guidelines only and may vary considerably depending on grade of plastic, fillers, surface finish, etc. Recycling information = thermoset [Pg.54]

Suggested adhesives include urea-formaldehyde, epoxy-polyamine, neoprene, nitrile-phenolic, styrene-butadiene, phenolic-polyvinyl butyral, polysulfides, furans, polyesters, and polyurethanes. [Pg.150]

Another important diallyl monomer is diallyl phthalate (DAP), prepared from phthalic anhydride and allyl alcohol. [Pg.74]

There are two major allyl plastics, diallyl phthalate (DAP) and diallyl isophthalate (see Diallyl phthalate). Both of these are widely used in fiber reinforced forms. The allyl plastics are usually compression or... [Pg.100]

Other thermosetting polymers are cyanate esters (CEs), benzoxazines, PU acrylates, bismaleimides (BMIs), dicy-clopentadienes (DCPDs), diallyl phthalates (DAPs), etc. Formulations based on these polymers are used for specific applications where their particular properties are required. For example, DAP has long been the material of choice for electrical components where long-term reliability is required. [Pg.520]

Four types of polyester molding compounds may be recognized [14] (1) dough-molding compound (DMC), (2) sheet-molding compound (SMC), (3) alkyd-molding compositions, sometimes referred to as polyester alkyds, (4) diallyl phthalate (DAP) and diallyl isophthalate (DAIP) compounds. [Pg.444]

Diallyl phthalate (DAP) is a diester of phthalic acid and allyl alcohol and contains two double bonds. [Pg.445]

All TP or TS matrix property can be improved or changed to meet varying requirements by using reinforcements. Typical thermoplastics used include TP polyesters, polyethylenes (PEs), nylons (polyamides/ PAs), polycarbonates (PCs), TP polyurethanes (PURs), acrylics (PMMAs), acetals (polyoxymethylenes/POMs), polypropylenes (PPs), acrylonitrile butadienes (ABSs), and fluorinated ethylene propylenes (FEPs). The thermoset plastics include TS polyesters (unsaturated polyesters), epoxies (EPs), TS polyurethanes (PURs), diallyl phthalates (DAPs), phenolics (phenol formaldehydes/PFs), silicones (Sis), and melamine formaldehydes (MFs). RTSs predominate for the high performance applications with RTFs fabricating more products. The RTPs continue to expand in the electronic, automotive, aircraft, underground pipe, appliance, camera, and many other products. [Pg.14]

There are two major allyl plastics, diallyl phthalate (DAP) and diallyl isophthalate (DAIP). Both of these are widely used in fiber RP forms. The allyl plastics are usually compression or transfer molded performing well in automated equipment (Chapter 5). They retain their physical and electrical characteristics under prolonged exposure to severe environmental conditions. They have high heat and moisture resistance, excellent electrical performance, good chemical resistance, dimensional stability, and low creep. These plastics are used where they provide environmental resistances. [Pg.154]

These modifications are necessary to provide the working time-temperature relationship required for screw plasticating. The most commonly used injectionmolding thermosetting materials are the phenolics. Other thermosetting materials often molded by the screw-injection process include melamine, urea, polyester, alkyd, and diallyl phthalate (DAP). (Source Chanda, M. and S. K. Roy, Plastics Technology Handbook, Marcel Dekker, Inc., New York, NY, 1987). [Pg.139]
