Polymers formed by a straightforward linking together of monomer units, with no loss or gain of material, are called addition polymers or chain-growth polymers.A listing of some important addition polymers and their monomer precursors is presented in the following table. chemical is abrasive, viscous in nature, or has a Specific Gravity greater than 1.1. Here are a few details on some of the modern variations and their common uses. Polycarbonate. Tests such as these provide information on how a plastic, such as polycarbonate, will change and modify their structure. PC is a special type of polyester used as an engineering plastic owing to its exceptional impact resistance, tensile strength, ductility, dimensional (26.7b) gives LOI ≈ 0.60–0.425 × 0.875 ≈ 0.23. 24936-68-3 - Lexan - Similar structures search, synonyms, formulas, resource links, and other chemical information. The estimated dietary intake of BPA from polycarbonate is more than 4000 times lower than the maximum acceptable daily dose for BPA, established by the U.S. Environmental Protection Agency. Carbonic acid, polyester with 4,4'-isopropylidenediphenol. They may also be used in other consumer goods. Shrink Rate Bisphenol-A-polycarbonate. Though polycarbonate sheeting was initially and concurrently developed in the mid-20th century by GE and Bayer, the current plastics marketplace features a variety of developers who each possess a unique polycarbonate formula and production process.

Water, vegetable oils, solutions of neutral salts, aliphatic hydrocarbons and alcohols are also included in this category. 288-316 °C (550-600 °F) *** Typical Mold Temperature. Chemical compatibility of thermoplastics e.g. CAS NO:25037-45-0; Chemical name:Polycarbonate ; physical and chemical property of 25037-45-0, Polycarbonate is provided by ChemNet.com BPA is found in polycarbonate plastics and epoxy resins.
Polycarbonate plastics are often used in containers that store food and beverages, such as water bottles. Bisphenol A (BPA), a colourless crystalline solid belonging to the family of organic compounds; its molecular formula is C 15 H 16 O 2.

It is available commercially in both pellet and sheet form. Polycarbonate plastic contains Bisphenol A (BPA) as a key building block. Many polymeric materials having chain-like structures similar to polyethylene are known. Polycarbonate chemical resistance is the worst against substances such as Acetic Acid Solution, Ammonium Carbonate Solution, Benzene, Chloroform, Ethyl Acetate, Methyl, Ethyl Ketone, Methyl Chloride, and Toluene. 59 MPa (8500 PSI) *** Flexural Strength. The most serious deficiencies are poor weatherability and chemical resistance.
