  • Labware Chemical Resistance Table
    Labware Chemical Resistance Table Interpretation of Chemical Resistance The Chemical Resistance Chart that follows is a general guide only. Because so many factors can affect the chemical resistance of a given product, you should test under your own conditions. Effects of Chemicals on Plastics Chemicals can affect the strength, flexibility, surface appearance, color, dimensions or weight of plastics. The basic modes of interaction which cause these changes are: (1) chemical attack on the polymer chain, with resultant reduction in physical properties, including oxidation; reaction of functional groups in or on the chain; and depolymerization; (2) physical change, including absorption of solvents, resulting in softening and swelling of the plastic; permeation of solvent through the plastic; dissolution in a solvent; and (3) stress cracking from the interaction of a “stress cracking agent” with internal or external stresses. Mixing and/or dilution of certain chemicals can be potentially dangerous. The reactive combination of different chemicals or compounds of two or more classes may cause an undesirable chemical effect or result in an increased temperature, which can affect chemical resistance (as temperature increases, resistance to attack decreases). Other factors affecting chemical resistance include pressure and internal or external stresses (e.g. centrifugation), length of exposure, and concentra tion of the chemical. 608 www.thermoscientifi c.com appendix Environmental Stress Cracking Environmental stress cracking is the failure of a plastic material in the presence of certain types of chemicals. This failure is not a result of chemical attack. Simultaneous presence of three factors causes stress cracking: tensile stress, a stress cracking agent and the inherent susceptability of the plastic to stress cracking.

  • Adhesive Bonding of Polyolefin Edward M
    White Paper Adhesives | Sealants | Tapes Adhesive Bonding of Polyolefin Edward M. Petrie | Omnexus, June 2013 Introduction Polyolefin polymers are used extensively in producing plastics and elastomers due to their excellent chemical and physical properties as well as their low price and easy processing. However, they are also one of the most difficult materials to bond with adhesives because of the wax-like nature of their surface. Advances have been made in bonding polyolefin based materials through improved surface preparation processes and the introduction of new adhesives that are capable of bonding to the polyolefin substrate without any surface pre-treatment. Adhesion promoters for polyolefins are also available that can be applied to the part prior to bonding similar to a primer. Polyolefin parts can be assembled via many methods such as adhesive bonding, heat sealing, vibration welding, etc. However, adhesive bonding provides unique benefits in assembling polyolefin parts such as the ability to seal and provide a high degree of joint strength without heating the substrate. This article will review the reasons why polyolefin substrates are so difficult to bond and the various methods that can be used to make the task easier and more reliable. Polyolefins and their Surface Characteristics Polyolefins represent a large group of polymers that are extremely inert chemically. Because of their excellent chemical resistance, polyolefins are impossible to join by solvent cementing. Polyolefins also exhibit lower heat resistance than most other thermoplastics, and as a result thermal methods of assembly such as heat welding can result in distortion and other problems. The most well-known polyolefins are polyethylene and polypropylene, but there are other specialty types such as polymethylpentene (high temperature properties) and ethylene propylene diene monomer (elastomeric properties).

  • 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.

  • Thz Materials
    THz Materials Terahertz (THz) radiation is located in the spectral region ~0.1-10 THz (~3 mm - 30 µm, 3 cm-1 - 300 cm-1 ) between the microwave and mid infrared range of the electromagnetic spectrum. In comparison with visible or infrared waves, THz radiation can penetrate into organic materials such as skin, plastics, cloth, or paper products. Because of low photon energy involved, it does not cause any damage associated with ionizing radiation (e.g. X-rays). THz waves do not penetrate into metals. These properties can be used in process (e.g. drugs manufacturing) and quality control as well as in THz imaging. It is also of great current interest for such applications as safety control, packaging inspection, semiconductor characterization, chemical composition analysis, and biomedical investigations, with great promise for spectroscopy, defense imaging, and security applications. Fig. 2. The THz signals transmitted through air and HRFZ-Si.(*) Traditionally for THz applications we use High Resistivity Float Zone The complex dielectric permittivity of silicon depends on its Silicon (HRFZ-Si) as it is the most investigated substance for operating conductivity (i.e. free-carrier concentration). Figure 3 shows the within this range and has a good transmission performance. In parallel dielectric permittivity of silicon at 1 THz with different impurity with this material we have been investigating other materials which concentration. For low impurity concentration the dielectric also can be utilized in THz range. permittivity is almost a real value, which is approximately equal Below you can see transmission spectra and other characteristics of to the high frequency dielectric permittivity.
