Chemical Blowing Agent (CBAs) are substances commonly used in the manufacturing of materials such as plastics, rubber, and foam products. These agents are added to the raw materials during the manufacturing process to create a reaction that releases gas and causes the material to expand. This expansion produces a foam-like texture that can be used in a variety of applications.
CBAs are typically classified as either exothermic or endothermic blowing agents. Exothermic blowing agents produce heat as they react, while endothermic blowing agents absorb heat. Both types of CBAs work by breaking down into gas when exposed to high temperatures, causing the material to expand and form a foam.
Some of the most common applications of CBAs include the production of insulation materials, cushions, packaging materials, and footwear. They are used to create lightweight, durable products that have good insulation properties and absorb shocks and impacts.
OBSH (Oxybis (benzenesulfonyl hydrazide)) is a Chemical Foaming Agents that is commonly used in the production of foamed plastics and rubber products. It releases nitrogen gas when heated, causing the material to expand and form a foam-like texture.
Foaming Agent OBSH is a relatively new blowing agent that has gained popularity in recent years due to its low toxicity and environmental impact compared to other blowing agents such as azodicarbonamide (ADCA) or chlorofluorocarbons (CFCs). It is also known for producing consistent and uniform foam structures in a variety of materials.
Some of the common applications of OBSH include the production of closed-cell foam insulation, shoe soles, and other molded foam products. It is also used in the manufacture of polyolefin foam products such as EVA and PE foams.
In addition to its low environmental impact and consistent foaming properties, OBSH Blowing Agent is also favored by manufacturers due to its high decomposition temperature and relatively low processing temperatures compared to other blowing agents. It also produces less odor and fewer hazardous byproducts than other blowing agents, making it a safer option for both workers and consumers.
While OBSH has many advantages as a blowing agent, it is important to note that it is still a chemical substance that requires careful handling and storage.
