Isotron line of HCFCs used as physical blowing agents for PUR, PS, and PE.
Organotin stabilizers offered for rigid PVC. Thermolite 175, 175C, 310 and 310C are liquid organic stabilizers. Thermolite System 4 is a multifunctional stabilizer-lubricant for PVC pipe extrusion. Thermolite 176, based on tin technology, is a part-for-part replacement for Thermolite 175C and Thermolite 310C. Superior cost/performance, color hold, and odor are among Thermolite 176's reported advantages.
Thermolite T-133 and T-137 for injection molding; T-137, T-34, and T-31 Super for siding and profiles; and Thermolite T-149 for foam profiles. Thermolite 31 is used in every process (profile, sheet, pipe), as well as any PVC or CPVC polymer or copolymer.
For rigid PVC containers and extruded sheet, Thermolite 31, 66 and 108 are recommended depending on formulation and equipment variables. General-purpose bottle stabilizers with improved cost/performance are in development.
Thermolite 350 and other customized organotin maleate stabilizers for calendered rigid PVC film/sheet where resistance to sulfide staining is required. Tin mercaptides available for products not requiring sulfide stain protection.
Radiation and heat stabilizers for PVC medical devices and packaging are said to offer resistance to color degradation and loss of physical properties upon exposure to gamma irradiation.
Thermolite 831 and 813 octyltins are major stabilizers for use in food-grade bottle and sheet applications. Also octyltins based on a mono-octyltin derivative and FDA-approved.
Metablen MBS impact modifiers for rigid PVC bottles, sheet, film, and injection molding. FDA-approved for food-grade PVC.
Metablen S weatherable silicone-acrylic impact modifiers for high-performance rigid PVC applications such as sheet, profiles, and injection molding. Metablen P acrylic processing aids used in any rigid PVC applications as well as flexible PVC.
Durastrength 200 weatherable acrylic impact modifier for rigid PVC siding, profiles, and injection molding.
Series of Durastrength and Thermocel multifunctional systems used for weatherable rigid siding, profiles, and PVC foams.
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.
Dimethylaminoethanol (DMAE) is an effective, economical amine catalyst for flexible and rigid PUR foams. Reportedly reduces viscosity of the polyol mix, offers solvent properties to help disperse polyol-mix components, and provides good latitude in adjusting cream and rise times. When combined with tin catalysts, DMAE gives more independent control of foaming reaction than other amine catalysts.
The continued evolution of thermoplastic composites just got even more interesting with this week’s launch by Arkema of the first range of a novel family of liquid thermoplastics that are transformed via reactive closed-mold processes such as room-temperature infusion, RTM, and flex-molding as used for composite thermosets.
Arkema's liquid thermoplastics are based on a high-molecular-weight acrylic and can be transformed using the same processes as composite thermosets.
