The study has been done as a screening, that is, it provides a snapshot of the occurrence of selected plasticisers and sweeteners, both in regions most likely to be polluted as well as in some very pristine environments. The pla- sticisers analysed were long chained phthalates and adipates, and the sweeteners analysed were aspartame, cyclamate and sucralose. The purpose of the screening was to elucidate levels and pathways of hitherto unrecognized pollutants. Thus the samples analysed were taken mainly from sewage lines, but also in recipients and biota, both in assumed hot-spot areas and in background areas.

Four Plastics Exempted from CPSIA Third Party Testing of Phthalates
Issue No.: 05/16/TCD Four Plastics Exempted from CPSIA Third Party Testing of Phthalates A Notice of Proposed Rulemaking exempting four plastics from phthalates testing under the CPSIA was approved by the Consumer Product Safety Commission (CPSC) on 9 August 2016. The decision came following a research conducted by the Toxicology Excellence for Risk Assessment (TERA) and other similar researches by the CPSC on the presence of eleven phthalates in four plastics used in children’s toys and child care articles. Once the rule has been approved, manufacturers shall not be required to conduct third-party testing in assuring compliance with the phthalate prohibitions for these four plastics. These four exempted plastics are: ¾ Polypropylene (PP) ¾ Polyethylene (PE) ¾ High Impact Polystyrene (HIPS) ¾ Acrylonitrile Butadiene Styrene (ABS) However, products made from the above plastics must continue to comply with Section 108 of CPSIA in which the “accessible plasticized component parts and other component parts made of materials that may contain phthalates” shall not contain any of the prohibited phthalates in concentration greater than 0.1% in children’s toys and child care articles. The six prohibited phthalates are: CPSIA Section 108 Phthalates Limit Permanent ban for use in children’s DEHP: di-(2-ethylhexyl) phthalate 0.1% toys or child care articles DBP: dibutyl phthalate 0.1% BBP: benzyl butyl phthalate 0.1% Interim ban for use in toys that can be DINP: diisononyl phthalate 0.1% put in the mouth or child care articles DIDP: diisodecyl phthalate 0.1% DnOP: di-n-octyl phthalate 0.1% Phthalates are generally used as plasticizers or softener of certain plastics. -
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. -

Influence of Different Polymeric Matrices on the Properties of Pentaerythritol Tetranitrate
Defence Science Journal, Vol. 71, No. 2, March 2021, pp. 177-184, DOI : 10.14429/dsj.71.16132 © 2021, DESIDOC Influence of Different Polymeric Matrices on the Properties of Pentaerythritol Tetranitrate Ahmed Elbeih*, Mahmoud Abdelhafiz, and Ahmed K. Hussein Military Technical College, Cairo, Egypt *E-mail: [email protected] ABSTRACT Six different polymeric matrices were fabricated to reduce the sensitivity of PETN (Pentaerythritol tetranitrate). The polymeric matrices used were individually based on Acrylonitrile butadiene rubber (NBR) softened by plasticizer, styrene-butadiene rubber (SBR) softened by oil, polymethyl methacrylate (PMMA) plasticised by dioctyl adipate (DOA), polydimethylsiloxane (PDMS), polyurethane matrix, and Fluorel binder. A computerised plastograph mixer was utilised for producing three polymer-bonded explosives (PETN-NBR, PETN-SBR, and PETN-PDMS) based on the non-aqueous method. A cast-cured method was used to prepare PBX based on polyurethane (PETN-HTPB), while the slurry technique was used to prepare beads of PETN coated by either fluorel binder (PETN-FL) or based on PMMA forming (PETN-PMMA). The heat of combustion and sensitivities were investigated. The velocity of detonation was measured, while the characteristics of the detonation wave were deduced theoretically by the EXPLO 5 (thermodynamic code). The ballistic mortar experiment was performed to determine the explosive strength. By comparing the results, it was found that PDMS has the highest influence on decreasing the impact sensitivity of PETN, while the cast cured PETN-HTPB has the lowest friction sensitivity. On the other side, PETN-FL has the highest detonation parameters with high impact sensitivity. Several relationships were verified and the matching between the measured results with the calculated ones was confirmed. -

Surface Modification of Engineering Plastics Through Swelling In
#2008 The Society of Polymer Science, Japan Surface Modification of Engineering Plastics through Swelling in Supercritical Carbon Dioxide By Toshimi TAKAJO,1;2 Atsushi TAKAHARA,1;Ã and Takefumi KICHIKAWA2 In order to improve the tribological characteristics of polymer materials, the authors tried to impregnate the surface of engineering plastics with the lubricating oil by using supercritical carbon dioxide. The oil impregnation ratio on crystalline polymer was influenced by both the glass transition temperature (Tg) and the degree of crystallinity. In case of using the polymer possessing lower Tg with large difference between the Tg and treatment temperature, the higher impregnation ratio was obtained, and the crystallite in crystalline polymer prevented the impregnation of lubricating oil. The results of polarized optical microscopic observations and FT-IR spectroscopy studies indicated that the lubricating oil was preferentially impregnated to the amorphous region in crystalline polymer, and the high-concentration layer of lubricating oil having the thickness of ca. 30 mm was formed at the vicinity of surface area. The result obtained in this study, which reports the preferential lubricating oil impregnation to the surface of crystalline polymer under supercritical carbon dioxide, suggests that the tribological characteristics of crystalline polymer would be improved by applying this oil impregnation method without sacrificing the bulk mechanical strength. KEY WORDS: Supercritical Carbon Dioxide / Oil Impregnation / Engineering Plastic / Tribology / Crystallinity / Many studies carried out by utilizing supercritical fluid have lubricating oil at high temperature over long periods of time to been recently reported, and the representative examples of the impregnate the product with lubricating oil.

A Review of Human Exposure to Microplastics and Insights Into Microplastics As Obesogens
REVIEW published: 18 August 2021 doi: 10.3389/fendo.2021.724989 A Review of Human Exposure to Microplastics and Insights Into Microplastics as Obesogens Kurunthachalam Kannan* and Krishnamoorthi Vimalkumar Department of Pediatrics and Department of Environmental Medicine, New York University School of Medicine, New York, NY, United States The ubiquitous exposure of humans to microplastics (MPs) through inhalation of particles in air and ingestion in dust, water, and diet is well established. Humans are estimated to ingest tens of thousands to millions of MP particles annually, or on the order of several milligrams daily. Available information suggests that inhalation of indoor air and ingestion of drinking water bottled in plastic are the major sources of MP exposure. Little is known on the occurrence of MPs in human diet.
