Ernest Ravindran,a K.B.R.Varma.b aDielectric Materials Division, Central Power Research Institute, Bangalore : 560 080, India bMaterials Research Centre, Indian Institute of Science, Bangalore: 560012,India E-mail:*thomas@cpri.in Abstract: Materials with high dielectric constant are in Polymethyl methacrylate (PMMA), also known as acrylic or plexiglas, is a high volume amorphous, transparent and colorless commodity thermoplastic that can be easily processed and converted into many finished and semi-finished products.. PMMA is used to create interior and exterior panels, trim, bumpers, fenders and other moulded parts. Max Temp. Typical Properties Date Issued: Nov 2015 Supersedes: Feb 2015 Product Data Sheet ZEONEX K26R Cyclo Olefin Polymer (COP) is an engineered plastic that provides excellent optical properties including high transparency, low birefringence, low water absorption, and excellent mold processability. Plastic Material Data Sheets. Verton, long glass fiber filled materials, by LNP, are excellent metal replacement materials. Automotive & Transportation. Plexiglass sheets can be easily heat formed without loss of optical clarity. PMMA ignites very quickly. The thermal conductivity of polymethyl methacrylate (PMMA) and borosilicate crown glass BK7 has been studied. TPX ® has excellent release properties due to its exceptionally low surface tension (24 dyne/cm), which is second only to flouropolymers such as PTFE. The transient hot-wire technique has been employed, and measurements cover a temperature range from room temperature up to 350 K for PMMA and up to 500 K for BK7. properties (such as stiffness and strength) in a plastic material, it also means that the material is difficult to process. 01 Starcoat PMMA & Starcoat PMMA THIX Liquid Waterproo≤ng ovember 201 | Ref 200020X V.1 Axter Ltd West Road, Ransomes Europark, Ipswich, Suffolk, IP3 9SX | 01473 724 056 | info@axterltd.co.uk | www.axter.co.uk-olvent-free.S - Test certificates and technical approvals (ETA, … Applications for G10, FR4 Thermosets.

Nylon 6-6 offers better properties than nylon 6 without being as costly as nylon 4-6. Also, you may want to use our Plastic Material Selection Guide or Interactive Thermoplastics Triangle to assist with the material selection process based on your application requirements. 1500. materials suppliers. Compare various plastic materials using specific property and design criteria. It is not a datasheet dump: every listed material is an internationally recognized generic material. The above mentioned data have been obtained by tests we consider as reliable. The glass transition temperature of atactic PMMA is 398 K (125 °C). Commercial PMMA is often copolymerized with comonomers other than methyl methacrylate. Cellulose, for example, is a polymer, but it cannot be processed like a plastic material unless it is modified. There are a lot of materials, and each has a lot of properties. MSDS (MATERIAL SAFETY DATA SHEET) PRODUCT MSDS-PMMA-111 PMMA 1/9 1. Polymethacrylates (PMMA, Plexiglas) Properties and Applications. The Tg of these products can vary, ranging broadly from approximately 360 K to 430 K … Power generation components; High-temperature applications; Structural parts; Printed circuit boards; Contact a Dielectric Manufacturing knowledge expert to discuss the use of epoxy resins for fabrication of your parts. This information is, to the best of our knowledge, accurate and reliable to the date indicated. This material tends to creep. Acrylic PMMA is a tough, highly transparent material with excellent resistance to ultraviolet radiation and weathering.It can be colored, molded, cut, drilled, and formed. The enhancement of fatigue properties are especially important in such applications that suffer dynamical loads, as is the case of PMMA bone cements, constantly subject to the loads and stresses caused … The technique is applied here in a novel way that minimizes all remaining thermal-contact resistances. Call 800-367-9122 or email sales@dielectricmfg.com. See all suppliers Are you a supplier? For chemically resistant plastic, view our Chemical Resistance of Plastics chart. PMMA properties make it the ideal material for several applications in sectors like transportation, architecture, electronics and health. APPLICATION: LCD Light Guide Plate, Mobile Phone LCD Cover. The thermal stability of standard PMMA is only 65 o C. Heat-stabilised types can withstand temperatures of up to 100 o C. PMMA can withstand temperatures as low as -70 o C. Resistance to temperature changes is very good.. Fire behaviour. Find, compare and connect. Acrylic is an economical alternative to polycarbonate (PC) when extreme strength is not necessary. Release properties. 2 PHYSICAL CONSTANTS IN SI UNITS Absolute zero of temperature – 273.15 °C Acceleration due to gravity, g 9. Thanks to its optical properties which are far superior to those of glass, PMMA is an exceptional material used in a wide range of industrial sectors (construction, automotive, photovoltaic panels, etc.) Fatigue data demonstrated that the functionalisation of G via silanisation with MPS is a highly effective solution to obtain PMMA bone cements with superior mechanical performance. Get in touch quickly and easily with suppliers to ask questions or source a material. CHEMICAL PRODUCT AND COMPANY IDENTIFICATION A. PMMA can be also polymerized anionically, yielding syndiotactic and isotactic polymers. Most commercial grades of PMMA, however, are atactic.
