Vikoflex 7170 epoxidized soybean oil and Vikoflex 7190 epoxidized linseed oil are high-oxirane, FDA-sanctioned products that reportedly combine optimum heat and light-stabilizing action with true polymeric plasticizer performance. Low odor, low migration, and resistance to extraction reportedly make them suitable for all flexible, semi-rigid and rigid PVC compounds. Vikoflex 7190 recommended for food-contact and medical applications where very little or no metallic stabilizer is used.
Also Vikoflex 4050 low-temperature epoxy ester plasticizer and low-viscosity esters of epoxidized soybean and linseed acids.
Drapex epoxidized oil and ester plasticizers for PVC include Drapex 4.4 (octyl epoxy tallate), Drapex 6.8 (epoxidized soybean oil), and Drapex 10.4 (epoxidized linseed oil). Drapex 4.4 said to impart excellent low-temperature flexibility to PVC. Used in plastisols and organosols, it offers low viscosity and solvating action. Drapex 6.8 and 10.4 epoxies, resistant to extraction and migration, are FDA-regulated for food-packaging use.
CLARIANT CORP., PIGMENTS
Uresin B carbamate resin for plasticizing PVC and other plastic films.
DOVER CHEMICAL CORP. SUB. OF ICC INDUSTRIES, INC.
Paroil liquid chlorinated paraffins as secondary plasticizers for flexible PVC.
DUPONT PACKAGING & INDUSTRIAL POLYMERS
Elvaloy resin modifiers for PVC include grades suitable for impact modification. Products have an extremely high molecular weight (250,000), which makes PVC compounds more durable. Reportedly, they have near zero extraction and essentially zero volatility, migration, and exudation, and provide heat, oil and UV resistance. Have been used commercially for calendered, extruded and injection molded products. Applications include office chair mats, pond liners, single-ply roofing, automotive interior applications, upholstery, wire and cable insulation, floor tile, hose and tubing, and footwear. Available as free-flowing pellets and in powders.
EASTMAN CHEMICAL CO.
Eastman plasticizers for PVC include phthalates as well as adipates and trimellitates. Eastman DOTP, dioctyl terephthalate, offered as a replacement for DOP and similar plasticizers in applications requiring improved durability, good electrical properties, and improved automotive fogging resistance. Allows use of PVC in contact with furniture finishes because it has little tendency to migrate and soften nitrocellulose lacquers. Other Eastman grades include TXIB for applications requiring low plastisol viscosity and PA-5, which promotes adhesion to metal.
EMERY OLEOCHEMICALS PLASTIC SOLUTIONS
Edenol epoxy plasticizers, low-temperature and specialty polymeric plasticizers.
Edenol products add flexibility, enhance compatibility with polymers and fillers, and function as heat stabilizers in PVC applications. Used successfully in the areas of electrical tapes, pressure-sensitive tapes, decals and automotive applications.
Edenol 9058 (DOZ) monomeric plasticizer used in applications such as film and decals offers superior low-temperature properties as well as permanence and weatherability. Edenol 9762 recommended for electrical tapes and pressure-sensitive tapes and also in adhesive tapes because of its resistance to migration into rubber or acrylic-based adhesives.
EXXONMOBIL CHEMICAL CO. POLYMERS GROUP
Jayflex plasticizers, used alone or in custom blends include branched and linear phthalates such as diisohexyl (DHP), diiso-hepryl (77), diisononyl (DINP), diisodecyl (NOP), ditridecyl (DTDP), undecyl dodecyl (UDP), di-L-nonyl (L9P), di-L-nonyl, undecyl (L911P), and di-L-undecyl (L11P); trimelli-tates such as triisooctyl (TIOTM) and tri-isononyl (TINTM); adipates such as diisono-nyl (DINA), diisooctyl (DIOA), diisodecyl (DIDA), and ditridecyl (DTDA); and extenders and specialty plasticizers.
Linear C9 phthalate plasticizer, Jayflex L9P, provides lower volatility and fogging in automotive vinyls and is useful in roofing membranes and pond liners where superior stability is required.
KENRICH PETROCHEMICALS, INC.
Low-cost, proprietary plasticizers include aromatic hydrocarbons compatible with PVC, rubber, acrylonitrile, and SAN.
Kenplast G low-viscosity mixture of alkyl-ated naphthalenes and phenanthrenes is an extender for epoxies, a secondary plasticizer for PVC, and a reportedly excellent compati-bilizer for PVC/vinyl acetate combinations. When used in place of DOP, Kenplast G reportedly is more solvating than ester-type plasticizers, thus contributing to build in plastisols and enhance elongation.
Kenflex resins are derived from formaldehyde condensation of aromatic hydrocarbons. These nonvolatile, very high-flash-point solids reportedly impart in-process flexibility at elevated temperatures without detracting from the finished product's properties once it has been cooled. Available in various solvent and compounded forms for specific uses such as compatibilization of rubbers and plastics, and enhancing of mold release of hard-to-handle materials.
Plasticizers derived from cumyl phenol available as either glycidylether or acetate for use as a reactive diluent and flexibil-izer for epoxies, PVC and urethanes. Higher temperature forms such as benzoate Kenplast ESB are useful in extrusion of PVC, urethane RIM, and in processing nylons. Cumyl phenyl benzyl ether is said to be an effective processing aid for extrusion of styrenics, SAN, poly-sulfones and phenylene oxide-based resins, as well as a compatibilizer for elastomers in PS, nylon, polyester and ABS.
Mesamoll plasticizer based on alkyl sulfonic ester of a phenol is said to have superior compatibility with PVC, resulting in flexible vinyls with good mechanical, thermal and electrical properties. Mesamoll and Mesamoll II lower-volatility versions also used in PUR caulk/sealant compounds where properties of low viscosity, hydrolysis resistance, extraction resistance and good solvency are needed.
Ultramoll 66M micronized powder version of dicyclohexyl phthalate can be useful in improving storage stability and fusing characteristics of low-temperature-fusing vinyl plastisols.
Disflamoll phosphate esters are used to impart flame retardance and flexibility to plasticized vinyls. Products include a range of aryl, alkylaryl and alkyl esters.
