Engineering Plastic KOCETAL refers to polyacetal resin of a copolymer type, And is a material of an excellent quality with features of excellent anti- friction/anti-wear, ® chemical-resistance, heat-resisting stability, precise dimensions KOCETAL and molding abilities. It is mainly applied in gear or roller, and is POLYOXYMETHYLENE 2 used for various 3 Engineering Plastic purposes over the fields of cars, office equipment and living materials. Properties of KOCETAL® - POM? Mechanical Themal Chemical Weatherability property property resistance Mechanical property The resin is highly crystalline, and has a great combination of toughness and rigidity. It is also resistant to fatigue, creep, and to abrasion thanks to abrasion thanks to its property of self-Iubrication. Thermal property Heat deflection temperature under Ioad and deterioration are other properties to ve considered with polymer. Amorphous resin deflects over the heat deflecton temperature, but polyacetal that is crystalline, doesn’t deflect a lot even over the heat deflection temperature. Thus, the limit of temperature should be considered after calculating the amount of creep deflection, depending on the design requirement. The estimated life of resin can be extrapolated by temperatured with polymer. Amorphous resin deflects over the heat deglection temperature, but polyacetal that is crystalline, doesn’t deflect a lot even over the heat deflection temperature. Thus, the limit of temperature should be considered after calculating the amount of creep deflection, depending on the design requirement. The estimated life of resin cam be extrapolated by measyring the change of property by temperature and using Arrhenius Plot. Because thermal stability of acetal copolymer resin cam be improved by addition df stabilizer, each grade shows different theramal stability. Homopolymer is more easily deteriorated than copolymer. Introduction of KOCETAL® Properties of KOCETAL® - POM? Chemical resistance The chemical resistance of a resin cam be judged by examining the solubiltity to chemicals, the increase of weight through absorption, and the influence pf chemicals on creep fracture. Polyacetal isn’t penetrated by organic solvents due to its crystalline property, but gains its weight slightly to aromatic, chlorine, ketonic, and ester solvents, which can change its mechanical property and size. Exceptionally, hexafluoroacetone dissolves polyacetal. Polyacetal is resistant to gasoline and lubricant, but if acid additive is used to improve the performance, it may become less resistant. Copolymer is resistant to alkali, but homopolymer is mot resistant to alkali chemicals. Polyacetal is generlly resistant to inorganic chemicals, but can be penetrated by ZnCL2 depending on temperature and concentration. The life of resin should be decided by considering the concentration of chemicals and temperature. In case pf resistance to hot water, homopolymer has fairly shorter life tham copolymer THe life of resin should be decided by concentration of chemicals and temperature. In case of resistance to hot water, if used for one year, the limit of temperature for copolymer is 90℃, and is 65℃ if used for ten years. Due to its chemical structure, homopolymer has fairly shorter life tham copolymer Weatherability Polycetal resin is not resistant to ultraviolet, but can be improved by addinf light stabilizer and ultraviolet absorber. The resistance to ultraviolet can be enhancedby staining carbon black and using proper pigment. However, in case of exterior use, the resin can be deteriorated by ultraviolet and ingluenced by SOx, NOx, ozone, etc. Therefore, serious consideration is needed for weatherability. The accelerated weather resistance test is cattied out by using Weather-OoMeter, Xenon arc, Fade-O-Meter. Good result doesn’t guarantee any crack or discoloration caused by exterior conditions.

  • Surface Microhardness, Flexural Strength, and Clasp Retention And
    ORIGINAL RESEARCH Surface Microhardness, Flexural Strength, and Clasp Retention and Deformation of Acetal vs Poly-ether-ether Ketone after Combined Thermal Cycling and pH Aging Salma Mahmoudd Fathy1, Radwa Mohsen Kamal Emera2, Reham Mohamed Abdallah3 ABSTRACT Aim: To evaluate the effect of combined thermocycling and artificial saliva pH on flexural strength, surface microhardness, as well as clasp retention and deformation of two different thermoplastic polymers. Materials and methods: Three groups were created, heat-cured polymethyl methacrylate, acetal, and poly-ether-ether ketone (PEEK) resins. Specimens were wrapped in plastic bags containing artificial saliva with three pH values (acidic 5.8, neutral 7.2, and alkaline 8.3). Two Aker clasps materials (acetal and PEEK), for premolar and molar, were stored in neutral salivary pH. Specimens were subjected to 2,000 thermocycles (5–55°C). Surface microhardness, flexural strength, and clasp retention and deformation were evaluated before and after aging. Data were analyzed by ANOVA, Tukey’s test, Student’s t-test, and paired t-tests (p < 0.05). Results: Thermal cycling at acidic and alkaline pH significantly decreased flexural strength and surface microhardness of acetal. It had no significant effect on PEEK properties. Poly-ether-ether ketone showed statistically significant higher mechanical properties in all groups. Acetal clasps exhibited a statistically significant deformation and a corresponding decrease in retention after thermocycling at neutral pH. Conclusion: Mechanical properties of acetal, as well as its clasp retention and deformation, significantly decreased after combining thermal and pH aging and thermal cycling in neutral pH, respectively. Meanwhile, PEEK clasps were not significantly affected. Clinical significance: Different intraoral variables may significantly affect mechanical performance, retention, and deformation of TMs used for denture base and clasp construction.

Since PTFE is immiscible with most polymers, the surface was etched using sodium naphthalene salt in tetrahydrofuran to increase its surface energy. The effects of two variables, namely PTFE content and PTFE etch time, on the mechanical properties of the composite were studied. Experiments were designed in accordance to response surface methodology (RSM) using central composite design (CCD). Samples were prepared with different compositions of PTFE (1.7, 4.0, 9.5, 15.0, or 17.3 wt %) at different PTFE etch times (2.9, 5.0, 10.0, 15.0, or 17.1 min).

For this purpose, in addition to qualitative analysis, it is necessary to understand the mechanisms of chemical reactions accompanying the decomposition process under the influence of temperature. Therefore, in this article, with the experimental results from the thermal analysis of the POM homopolymer of three various stages of life—POM-P—unprocessed sample; POM-R—recycled sample, and POM-O—sample waste—we took steps to determine the basic kinetic parameters using two well-known and commonly used kinetic models: Friedman and Ozawa-Flynn-Wall (OFW). Knowing the values of the course of changes in apparent activation energy as a function of partial mass loss, theoretical curves were fitted to the experimental data. The applied calculation models turned out to be consistent in terms of the nature of the curve changes and similar in terms of Ea in Citation: Majka, T.M.; the entire range of mass loss. Both kinetic models showed a very similar course of the Ea curves.

  • Morphology of Polyoxymethylene-Based Polymer Alloys
    Morphology of polyoxymethylene-based polymer alloys Shuichi Takamatsu, Tomomi Kobayashi and Tadashi Komoto* Department of Materials Engineering, Gunma University, Tenjin-cho, Kiryu, Gunma 376, Japan and Motoyuki Sugiura and Kazumine Ohara Nippon Oil and Fats Co. Ltd, Taketoyo-cho, Chita, Aichi 470-23, Japan (Received 1 November 1993; revised 16 February 1994) A transmission electron microscopic study was carried out on polymer alloys of polyoxymethylene(POM) with low density polyethylene (LDPE) and styrene/acrylonitrile-graftedLDPE (LDPE-g-PSAN) from the point of view that the compatibility of POM and LDPE will be improved by the grafted PSAN chain which has a solubility parameter close to that of POM, though POM and LDPE are immiscible with each other. Low temperature plasma etching followed by the carbon replica method were applied to examine the size and distribution of particles in LDPE and LDPE-g-PSAN in POM matrices by TEM. The size distribution curve of the dispersed particles had its maximum at a particle diameter of ~ 1.5 #m for LDPE and ~ 0.2/~m for LDPE-g-PSAN. It was also found from the TEM morphologies that the interaction of the particles with the POM matrix is stronger for LDPE-g-PSAN than for LDPE. This is accounted for by a difference in their solubility parameters. (Keywords: polymer alloy; polyoxymethylene; polyethylene) INTRODUCTION particular peroxide compounds, where the trunk polymer is composed of polyolefins and the graft polymer is vinyl Many immiscible polymer alloys are used as industrial polymers9'1°. This method was also applied to the materials. Immiscible polymers with highly different synthesis of a graft copolymer with LDPE as the trunk chemical natures tend to be phase-separated to a large polymer and styrene-acrylonitrile copolymer (PSAN) as extent, which leads to deterioration of their properties in the graft.

The study of injection-molded polymer gear perfor- power transmission — especially within automotive engineer- mance is important due to the significantly lower cost of injec- ing. Currently, there are a few design standards for polymer gear tion-molded gears when compared to machined gears. applications (Refs. 1–2) which have been mainly developed by modifying the existing metal gear design methods. However, it may be noted that the design guidance is only available in detail for POM and PA materials. This is a major limitation of the existing design methods, as new polymer materials are becom- ing available continuously. Furthermore, there is little evidence in the literature showing the validity of the methods, and in some cases poor correlation has been shown between the stan- dards and test results (Refs. 3–4). As a result, the use of polymer gears in higher-power applications is not widely accepted due to the lack of understanding of their performance.
