Polyimide is a polymeric plastic material, engineered for long term performance at very high temperatures, in excess of 250° C for prolonged periods of time. Polyimide is made from two key ingredients, which may each contain traces of impurities, such as water vapor, or even traces of iron from the chemical drums containing solvents used. Polyimides are a very interesting group of incredibly strong and astoundingly heat and chemical resistant polymers. Their strength and heat and chemical resistance are so great that these materials often replace glass and metals, such as steel, in many demanding industrial applications. The polyimide materials are lightweight, flexible, resistant to heat and chemicals. Therefore, they are used in the electronics industry for flexible cables, as an insulating film on magnet wire and for medical tubing. Polyimides are a class of polymers notable for chemical, wear, radiation, and temperature resistance, characteristics that have led to applications as diverse as aerospace engine housings and electronics packaging. The use of polyimides in the manufacture of hybrid circuits is increasing. These organic compounds are suited to thick and thin film applications because of their ability to be patterened, and desirable mechanical, chemical , thermal and electrical properties. Polyimides are a class of thermally stable polymers that are often based on stiff aromatic backbones. The chemistry of polyimides is in itself a vast area with a large variety of monomers available and several methodologies available for synthesis. The most widely practiced procedure in polyimide synthesis is the two-step poly(amic acid) process. It involves reacting a dianhydride and a diamine at ambient conditions in a dipolar aprotic solvent such as N,N-dimethylacetamide (DMAc) or Nmethylpyrrolidinone (NMP) to yield the corresponding poly(amic acid), which is then cyclized into the final polyimide. In Polyimide polymers, the double bonded Oxygen group is an appropriate site for local Water adsorption. To model this kinetically, it is assumed that at least one Water molecule is adsorbed on the specific site and - after some time - is desorbed. Polyimides have been of great interest in engineering and microelectronics for a number of applications owing to their unique property combinations. Polyimide can also withstand much higher temperatures (greater than 300OC) than most polymers. This property allows polyimide to accept vacuum depositions of metals better than Lexan. Polyimide is becoming widely used for many ultrathin film applications because of its superior strength. Major producers of polyimide film, Kaneka High Tech Materials(KHM) (Manufacturing facilities in Texas and Japan) and Dupont have reacted to this situation and have announced plans to significantly increase capacity sometime during the first half of 2002. Consumption of polyimide and other imide polymer resins in Asian countries other than Japan, including China, India, the Republic of Korea, Malaysia and Taiwan, has been growing rapidly in recent years despite the global economic recession	Introduction Facts about Polyimide Film Polyimides Polyimides - Info Msds Polyamide - Amine Resin Polyamide Blend Aromatic Polyimide Polymer Emarex Polyamide Resin Pyralin Polyimide Coating Polyimide Resin Rilsan BMV BLK T Polyamide Resin Polyimide resin Skybondo 700 Polyimide Resin Polyamide Products 3M Polyimide Film Tape Polyimide Laminate and Prepreg Polyimide - Polymer blends and Alloys Polyimide P84 High-performance coating Corin XLS Polyimide High Temperature Polyimide Composite Resin System Kapton polyimide film Polyimide Laminate and Prepreg Polyimide High Performance Solimide Study Carbonization behaviour of some polyimide resins reinforced with carbon fibers Laser Processing of Polyimide on Copper Low Temperature Curing of Polyimide Precursors by Variable Frequency Microwave A Continuum Model for Carbon Nanotube-Infused Polyimides Surface studies of polyimide thin films via surface-enhanced Raman scattering and second harmonic generation Synthesis and Characterization of Sulfonated Polyimide Polymer Electrolyte Membranes Thermal, oxidative and radiation stability of polyimides A study of polyimide thermoplastics used as tougheners in epoxy resins Patents Photosensitive polyimide resin composition Process for production of polyimide resins Polyimide Polyimides and polyimide-amides Polyimide derivatives Porous polyimide Polyimide precursors and polyimides Polyimide resin Polyimide manufacture Preparation of polyimide polymers Polyimides, process for the preparation thereof and polyimide resin compositions Company Profiles Company from China Another Company from China Company from Hyderabad Company from New Jersey Company from New York Technology Colorless Polyimides Evaluation of Transparent Polyimide for Flexible Solar Cell Substrates Polyimide Boosts High-Temperature Performance Polyimide Resins Resist Extreme Temperatures FPC with polyimide film substrate technology development	Production Process Synthesis and characterization of new alkali-soluble polyimides and preparation of alternating multilayer nano-films therefrom Converting Polyimide Labels Materials for Polyimide Synthesis Monomer and Polyimide Production for Radiation Shielding Purposes in Manned Space Exploration Synthesis and Characterization of New Soluble Polyimides Novel Polyimides Containing Alicyclic Units Synthesis and Characterization Synthesis and characterization of new inherent photoimageable polyimides Polyimides : chemistry & structure-property relationships Preparation and Characterization of an Aromatic Polyimide and Its Use as a Selective Membrane for H2O2 Synthesis and characterization of two series of polyimides as nonlinear optical materials Synthesis of Polyimides in Supercritical Carbon Dioxide Synthesis of Polymers Synthesis and Characterization of Polyimides with Twisted Configurations Applications Adhesiveless Copper on Polyimide for Flexible Circuit, HDI and Microvia Applications Polyimides as Adhesives: -Literature review Binding Resin for Diamond- and CBN Grinding Wheels Applications of a low contact force polyimide shank bolometer probe for chemical and biological diagnostics Copper on Polyimide Flexible Substrate For Ultra-Thin, High Performance Applications The Development of Ultra thin Polyimide for Laser Target and Other Applications Polyimides in Hybrid Circuit Processing Low - Melt Viscosity Polyimide Resins for Resin Transfer Molding (RTM) II Optical Fibers with Polyimide Coatings for Medical Applications Evaluation of HD4004 Photosensitive Polyimide for Semiconductor Applications Wafer Protection With Screen Printable Polyimide Market Polyimide fibre production and products Polyimide Flexible Laminate for Displays World Market for Polyimide Film SKC Kolon PI targets No. 1 spot in polyimide film market Polyimides and Imide Polymers Ube Industries Announces Its Tenth and Eleventh Expansion of Production Facilities for Polyimide Film Suppliers Polyimide Suppliers Worldwide Suppliers Indian Suppliers Suppliers of Polyimide Consultants Company from California Company from Denmark Company from Japan Company from New - York Expert Witness Order the CD ROM today
