On January 2, 2013, ExxonMobil Chemical Company stated that its world's largest ethylene steam cracker in Singapore began operations, which is part of the company’s multi-billion-dollar expansion project at Singapore Petrochemical Complex. The expansion has increased production capacity by 2.6 million tons/year, which has doubled the capacity of ExxonMobil Chemical Singapore.
The project includes 2 sets of new polyethylene units, 1 set of polypropylene units, 1 set of metallocene elastomer units, 1 set of oxo alcohol units and 1 set of aromatic hydrocarbon expanders. All of these projects have been completed and put into operation. This is ExxonMobil's first production of its proprietary specialty elastomers and metallocene-based polyethylenes in the Asia Pacific region. The expansion also made the Singapore plant the largest refinery and petrochemical complex of ExxonMobil.
Steve Pryor, president of ExxonMobil Chemical, said that this is ExxonMobil's largest chemical expansion project in its history. The base has become one of the most technologically advanced and competitive production bases in Singapore and Asia Pacific.
The expansion will increase the number of employees in the chemical plant by 50%, bringing the total number of employees of ExxonMobil's refinery and chemical complex in Singapore to 1,800.
Curing agents, also known as hardeners, are essential components of many polymer systems, including Epoxy Resins. Curing agents react with the epoxy resin to form a three-dimensional crosslinked network, resulting in a cured polymer with improved mechanical properties, chemical resistance, and thermal stability.
There are several types of curing agents, each with its own unique properties and applications. The most common type is amine-based curing agents, which react with the epoxy functional group to form a secondary amine and an alcohol. This reaction is exothermic and can be accelerated by heat, making it ideal for high-temperature applications.
Another type of curing agent is anhydride-based, which react with the epoxy group to form a cyclic acid anhydride and a hydroxyl group. These curing agents are typically used in applications where water resistance is critical, such as marine coatings and adhesives.
Other types of curing agents include phenolic, acid, and catalytic curing agents. Phenolic curing agents are used in high-temperature applications, while acid curing agents are used in low-temperature applications. Catalytic curing agents are used to accelerate the curing process and are typically used in combination with other curing agents.
The choice of curing agent depends on the specific application requirements, such as cure time, cure temperature, and final properties of the cured polymer. It is important to choose the correct curing agent to ensure that the final product meets the desired specifications.
In summary, curing agents are essential components of many polymer systems, including epoxy resins, and play a critical role in improving the mechanical, chemical, and thermal properties of the cured polymer. The choice of curing agent depends on the specific application requirements and must be carefully considered to ensure the final product meets the desired specifications.
