Esters as pitch plasticizers - Union Carbide Corporation
Esters as pitch plasticizers - Union Carbide Corporation Title: Esters as pitch plasticizers United States Patent 4715897 Abstract: Benzenepolycarboxylic acid esters, preferably phthalate or isophthalate acid esters are used as plasticizers in carbon/pitch mixes used in the production of extruded carbon and graphite electrodes. Inventors:
High Performance Carbon Fibers - American Chemical Society
began in 1956, when Union Carbide, now part of GrafTech International, opened its Parma Technical Center just outside Cleveland. The complex was one of the major laboratories of Union Carbide’s basic research program, modeled after the univer-sity-style corporate laboratories that became popular in the late 40s and 50s. These facilities

- Which citrate esters are used as plasticizers in ca?
- Other citrate esters reported as plasticizers in CA are tributyl citrate (TBC) and acetyl tributyl citrate (ATBC) , . When ATBC was used in CA, white and opaque films were obtained by casting. Further DSC analysis demonstrated the presence of a crystalline peak.
- When did Union Carbide become a company?
- In 1920, the company set up a chemicals division which manufactured ethylene glycol for use as automotive antifreeze. The company continued to acquire related chemical producers, including the Bakelite Corporation in 1939. The company changed its name to "Union Carbide Corporation" in 1957 and was often referred to as Carbide.
- Which carbohydrates are used as plasticizers in ca?
- The use of carbohydrates esters, such as α, β-glucose pentaacetate (GPA), α, β-glucose pentapropionate (GPP), α, β-glucose pentabutyrate (GPB) as plasticizers in CA with low volatility and good compatibility has been reported in some patents.
- What is Union Carbide & Carbon Corporation?
- Founded in 1917 as the Union Carbide and Carbon Corporation, from a merger with National Carbon Company, the company's researchers developed an economical way to make ethylene from natural gas liquids, such as ethane and propane, giving birth to the modern petrochemical industry.
- Why are plasticizers added to ca?
- Plasticizers are added to CA to increase workability, prevent degradation under processing conditions and ensure thermo-mechanical properties suitable for the intended final application. Moreover, inexpensive and non-toxic solvents enable its processing into fibers, films, and solid blocks.
- What is the molecular weight of ca plasticizers?
- The molecular weight of CA plasticizers ranges from 178 g mol −1 (diacetin) to 378 g mol −1 (tricresyl phosphate), with an average value of ∼260 g mol −1. It should be noted that high molecular weight plasticizers showed limited compatibility in CA , .
