Effects of Thymolphthalein on Thermo-Oxidative Stability of High Density Polyethylene in Melt and Solid States
The present work aimed to evaluate capability of a new molecular structure to stabilize polyethylene against thermal oxidation. Hence, effects of 3,3-bis(4-hydroxy-2-methyl-5-propan-2-ylphenyl)-2-benzofuran-1-one (thymolphthalein) on thermo-oxidative stability of high density polyethylene (HDPE) in both solid and melt states were investigated and compared with those of SONGNOX 1010, a comme...
متن کاملMicrosoft Word - Thermo-Oxidative Stability
The materials used in this study include HDPE (HD100 from M. Holland Company), PP (Polypropylene 3281 from Total Petrochemicals USA, Inc.) and HIPS (IS200 from M. Holland Company). Each polymer was then compounded with SureFlo at two different levels, 5 and 10%. A Q-500 thermogravemetric analyzer (TGA) was used for the study. In each experiment, the sample (typical size ~ 10 mg) was heated from...
متن کاملHigh Temperature Long Period Grating Thermo-Mechanically Written
An optical fiber transducer able to work in high temperature environments is experimentally demonstrated in the laboratory. It is based on a permanent long period grating (LPG) written using a new technique based on a thermo-mechanical approach. Device precision was experimentally checked by means of repetitive thermal cycles between 25 and 950 °C. In addition device stability was assured by ma...
متن کاملThermo-Oxidative Stability of SiOx-doped Diamondlike Carbon Studied via Environmental XPS and AFM
A broad array of carbon-based thin films, such as diamond, diamond-like carbon (DLC), and others, have been developed over the last several years [1]. These materials exhibit high strength and stiffness, low friction and wear, tolerance to withstand harsh physical and chemical conditions, and can form smooth, continuous, conformal coatings. This has resulted in their use in a wide range of appl...
متن کاملImproving Thermal Stability of Starch in Formate Fluids for Drilling High Temperature Shales
Starch is one of the most widely used biopolymers in water based drilling fluids to control fluid loss. The thermal stability of starch in common drilling fluids is low (93 °C). In this study, the thermal stability of starch has been evaluated in sodium/potassium formate and potassium chloride fluids. Samples of mud were prepared by formate salts (sodium and potassium) and potassium chloride wi...
