The glasssheets typically used are surfacing veils, chopped strands, choppedstrand mats, woven rovings, biaxial mats, continuous strands,unidirectional mats and/or a combination of these. Other specialtygrades available include UV absorbing, pigmented, and flame retardantgrades. In 2004, the price of vinyl esters ranged approximately from$1.50 to $2.00 per pound at truckload quantities.General PropertiesVinyl esters are known for their outstanding resistance to corrosionand a wide range of chemicals. Vinyl esters also have high impactstrengths, good elongations (3 to 10%), and high weight to strengthratios (SG = 1.1 to 1.3). The properties of vinyl ester resins areextremely versatile, and properties can be tailored to specificapplications by modifying the base resin and the composite glass fiberstructure. For example, by adding an elastomer to the bisphenol Abackbone, the tensile elongation, impact resistance, and abrasionresistance of vinyl esters are greatly increased. The addition of anepoxy novolac resin to its backbone results in superior oxidation, heat,and solvent resistance. The ignition resistance of vinyl esters is greatlyimproved by adding bromated resins to the polymer’s backbone and/orby adding antimony oxide. Unfilled vinyl esters are slow burning andhave low smoke emission. Vinyl esters are excellent electrical andthermal insulators and have outstanding resistance to thermal aging.Vinyl esters are chemically resistant to a wide variety of chemicals,including acids, alkalis, halogenated organics, caustics, and solvents.Typical Properties of Vinyl EsterAmerican EngineeringProcessing Temperature 250°F to 300°F 121°C to 149°CLinear Mold Shrinkage 0.0005 to 0.0010 in./in. 0.0005 to 0.0010 cm/cmMelting Point – –Density 64.3 to 71.2 lb./ft. 3 1.03 to 1.14 g/cm 3Tensile Strength, Yield 9.1 to 12.6 lb./in. 2 x 10 3 6.4 to 8.9 kg/cm 2 x 10 2Tensile Strength, Break 9.9 to 12.1 lb./in. 2 x 10 3 7.0 to 8.5 kg/cm 2 x 10 2Elongation, Break 3.4 to 5.5% 3.4 to 5.5%Tensile Modulus 4.4 to 5.2 lb./in. 2 x 10 5 3.1 to 3.7 kg/cm 2 x 10 4Flexural Strength, Yield 16.0 to 21.9 lb./in. 2 x 10 3 11.2 to 15.4 kg/cm 2 x 10 2Flexural Modulus 4.4 to 5.7 lb./in. 2 x 10 5 3.1 to 4.0 kg/cm 2 x 10 4Compressive Strength 16.5 to 42.0 lb./in. 2 x 10 3 11.6 to 29.5 kg/cm 2 x 10 2Izod Notched, R.T. 0.4 to 0.6 ft.-lb./in. 2.2 to 3.2 kg cm/cmHardness M110 - M115 Rockwell M110 - M115 RockwellThermal Conductivity – –Linear ThermalExpansionDeflection Temperature@ 264 psiDeflection Temperature@ 66 psiContinuousService Temperature1.8 to 2.1 in./in.-°F x 10 -5 3.2 to 3.8 cm/cm-°C x10 -5SI200°F to 248°F 93°C to 220°C– –– –Dielectric Strength 400 to 470 V/10 -3 in. 1.6 to 1.8 V/mm x 10 4Dielectric Constant@ 1 MHzDissipation Factor@ 1 MHzWater Absorption,24 hr.2.8 to 3.5 2.8 to 3.50.002 to 0.020 0.002 to 0.0200.10 to 0.30% 0.10 to 0.30%Typical Applications• Chemical – Adsorption towers, process vessels,storage equipment tanks piping, hood scrubbers• Miscellaneous – Sheet molding compounds,electrical equipment, flooring, fans72The Loctite ® Design Guide for Bonding Plastics, Volume 4
