Dispersants for Plastics Product Guide PERFORMANCE COATINGS THERMOPLASTICS & THERMOSETS DISPERSANTS PRODUCT GUIDE FOR PLASTICS HYPERDISPERSANTS FOR THERMOPLASTICS AND THERMOSETS Solplus™ and Solsperse™ hyperdispersants and coupling agents have been developed to meet the needs of the plastic industry, for both thermoplastic and thermoset polymers, as well as polyurethanes. THERMOPLASTIC MASTERBATCH AND COMPOUNDING Solplus™ DP310 hyperdispersant is recommended for the dispersion of organic and inorganic pigments and fillers in thermoplastic masterbatch and compound applications. It can be used in a variety of thermoplastic polymers including polyethylene, polypropylene, polystyrene, ABS and PVC.

Abstract: This paper reviews the current trends in replacing commonly used plasticizers in poly(vinyl chloride), PVC, formulations by new compounds with reduced migration, leading to the enhance- ment in mechanical properties and better plasticizing efficiency. Novel plasticizers have been divided into three groups depending on the replacement strategy, i.e., total replacement, partial replacement, and internal plasticizers. Chemical and physical properties of PVC formulations containing a wide range of plasticizers have been compared, allowing observance of the improvements in polymer per- formance in comparison to PVC plasticized with conventionally applied bis(2-ethylhexyl) phthalate, di-n-octyl phthalate, bis(2-ethylhexyl) terephthalate and di-n-octyl terephthalate. Among a variety of newly developed plasticizers, we have indicated those presenting excellent migration resistance and advantageous mechanical properties, as well as those derived from natural sources. A separate chapter has been dedicated to the description of a synergistic effect of a mixture of two plasticizers, primary and secondary, that benefits in migration suppression when secondary plasticizer is added to PVC blend.

  • Test Method: CPSC-CH-C1001-09.2
    Statement of Policy: Testing of Component Parts With Respect To Section 108 of the Consumer Product Safety Improvement Act A. Background The Consumer Product Safety Improvement Act (CPSIA) was enacted on August 14, 2008 (Pub. L. 110-314). Section 108 of the CPSIA permanently prohibits the sale of any “children’s toy or child care article” containing concentrations of more than 0.1 percent of three specified phthalates.1, 2 Section 108 also prohibits, on an interim basis, the sale of “any children’s toy that can be placed in a child’s mouth or child care article” containing concentrations of more than 0.1 percent of three additional phthalates pending the recommendation of a Chronic Hazard Advisory Panel (CHAP).3, 4 The CHAP will recommend to the Commission whether to make the interim ban permanent and whether other phthalates or phthalate alternatives should be declared banned hazardous substances. The terms “children’s toy,” “children’s toy that can be placed in a child’s mouth,” and “child care article” are defined in section 108 of the CPSIA. These prohibitions became effective on February 10, 2009. To gather comments and information about implementation of this section of the CPSIA, the Commission published a “Notice of Availability of Draft Guidance Regarding Which Children’s Products are Subject to the Requirements of CPSIA section 108; Request for Comments and Information,” on February 23, 2009 (74 FR 8058). Comments in response to the Notice demonstrate that many questions and concerns exist about the requirement that products comply with the phthalates limits of section 108 of the CPSIA and, specifically, the testing procedures used to determine the percentage of phthalates in such products.

They can contain a blend of chemicals, some of them added during the manufacture of plastic to improve their quality (additives) and others adsorbed from the surrounding environment. In light of this, a detailed study about the identification and quantification of target organic pollutants and qualitative screening of non-target compounds present on MPs was carried out in different types of samples: environmental MPs, collected from an Italian river, and pre-production MPs, taken from the plastic industry. Polychlorobiphenyls (PCBs), organochlorine pesticides (OCPs), and polycyclic aromatic hydrocarbons (PAHs) were chosen as target compounds to be quantified by Gas Chromatography-Mass Spectrometry (GC–MS), while the non-target screening was carried out by High Resolution Gas Chromatography-Mass Spectrometry (HRGC–MS). The target analysis revealed concentrations of 16 priority Polycyclic Aromatic Hydrocarbons by Environmental Protection Agency (EPA-PAHs) in the range of 29.9–269.1 ng/g; the quantification of 31 PCBs showed values from 0.54 to 15.3 ng/g, identifying CB-138, 153, 180, 52, and 101 primarily; and the detected OCPs (p,p’-DDT and its metabolites) ranged between 14.5 and 63.7 ng/g.

Synopsis Ion irradiation has been investigated as a route for the preparation of mechanically stable and highly durable cross linked sulphonated PEEK for fuel cell application. Ion irradiation was carried out using the University of Birmingham’s Scanditronix MC-40 Cyclotron operating at 11.7 MeV for H+ and 30 MeV for He2+ and the irradiated materials were characterized focusing on structural, thermal, morphological as well as dielectrical properties. Alterations produced in the molecular structure of amorphous PEEK by ion irradiation have been interpreted as due to chain scission and formation of cross links, as confirmed by sol-gel analysis in MSA using the well known Charlesby–Pinner equation. The thermal decomposition of irradiated PEEK was similar to that of untreated PEEK in that it occurred by a random chain scission process.

  • High Performance Ester Plasticizers
    High Performance Ester Plasticizers Abstract Traditional elastomer polymers, such as nitrile, polychloroprene, chlorinated polyethylene and chlorosulfonated polyethylene, have for years used moderate- to low- performance ester plasticizers. However, longevity requirements for rubber articles made from these elastomers have created a need for higher-performance ester plasticizers. With the increasing high-temperature demands required by automotive, other elastomers such as acrylic, high-saturated nitrile, epichlorohydrin and ethylene propylene diene monomer EPDM are replacing the more traditional elastomers. Plasticizers commonly used for the traditional and the high-temperature polymers are extractable, incompatible or too volatile. This paper provides information on plasticizers that are designed for traditional elastomers and high-performance polymers. The test data will include heat aging, extraction by hydrocarbons and low-temperature as molded after aging. The information provided indicates that the permanence of the plasticizer after these various agings is the key to the retention of physical properties. Introduction End uses for elastomer compounds are quite diverse, but they can be loosely categorized as being either general performance or higher performance applications. Each of these performance categories requires a different set of considerations in terms of compounding with ester plasticizers. An ester plasticizer, in its simplest concept, is a high-boiling organic solvent that when added to an elastomeric polymer reduces stiffness and permits easier processing.1 For general performance applications, compounders require moderate performance in several areas without particular emphasis on any one. Some general performance ester plasticizers used in the marketplace today are DOA, DIDA, DIDP, DOP, DINP and other phthalates and adipates made from straight-chain alcohols of 7–11 carbons in length.

  • Levels of Persistent Organic Pollutants in Several Child Day Care Centers
    Journal of Exposure Analysis and Environmental Epidemiology (2001) 11, 449 – 458 # 2001 Nature Publishing Group All rights reserved 1053-4245/01/$17.00 www.nature.com/jea Levels of persistent organic pollutants in several child day care centers NANCY K. WILSON,a JANE C. CHUANGb AND CHRISTOPHER LYU a aBattelle, Durham, North Carolina bBattelle, Columbus, Ohio The concentrations of a suite of persistent organic chemicals were measured in multiple media in 10 child day care centers located in central North Carolina. Five centers served mainly children from low-income families, as defined by the federal Women, Infants, and Children (WIC) assistance program, and five served mainly children from middle-income families. The targeted chemicals were chosen because of their probable carcinogenicity, acute or chronic toxicity, or hypothesized potential for endocrine system disruption. Targeted compounds included polycyclic aromatic hydrocarbons (PAHs), pentachloro- and nonyl-phenol, bisphenol-A, dibutyl and butylbenzyl phthalate, polychlorinated biphenyls (PCBs), organochlorine pesticides, the organophosphate pesticides diazinon and chlorpyrifos, and the herbicide 2,4-dichlorophenoxyacetic acid (2,4D). Sampled media were indoor and outdoor air, food and beverages, indoor dust, and outdoor play area soil. Concentrations of the targeted compounds were determined using a combination of extraction and analysis methods, depending on the media. Analysis was predominantly by gas chromatography/mass spectrometry (GC/MS) or gas chromatography with electron capture detection (GC/ECD). Concentrations of the targeted pollutants were low and well below the levels generally considered to be of concern as possible health hazards. Potential exposures to the target compounds were estimated from the concentrations in the various media, the children’s daily time–activity schedules at day care, and the best currently available estimates of the inhalation rates (8.3 m3 /day) and soil ingestion rates (100 mg/day) of children ages 3–5.
