CH is a flexible organic peroxide used in medium-temperature processes, ranging from 110°C to 150°C. It's suitable for applications requiring polymerization initiation, cross-linking, or curing. The product is available at a concentration of 70±1%, and can be blended into solutions tailored for specific needs, such as a 50% mix with isododecane or dibutyl phthalate, or a 25% solution with ethylbenzene and mineral oil. Custom blends can also be created to meet specialized requirements.
- CH is used in styrene polymerization processes, operating best at temperatures between 90°C and 120°C. It also acts as a reliable initiator for copolymers like acrylonitrile, acrylates, and methacrylates.
- This organic peroxide is highly effective as a curing agent for unsaturated polyester resins (UP resins) in high-temperature applications. It’s a go-to option for curing in processes like SMC, DMC, and BMC, with optimal temperatures ranging from 120°C to 170°C.
- CH is also used as a cross-linking agent for materials like natural rubber, silicone rubber, diene rubbers, and polyurethane, delivering dependable results in the production of various resins.
-
Packaging
CH is typically packaged in sturdy, 20 kg polyethylene drums to ensure safety during handling and transportation. Custom sizes and packaging options can be arranged based on customer needs.
-
Storage
To maintain its integrity, CH should be stored in tightly sealed containers in a well-ventilated area with a maximum temperature of 25°C. Avoid exposure to reducing agents like amines, acids, bases, or heavy metal compounds, and ensure that the product is not exposed to impact or friction.
-
Safe Handling
Store CH within the recommended temperature range to prevent potential safety risks. Exceeding these temperatures may lead to fire hazards.
Ensure the storage area is free from open flames and heat sources, with proper measures to prevent static discharge. Keep the product away from light, and make sure the space is well-ventilated.
For large quantities, use a separate storage facility. Keep the product away from reactive agents such as acids, bases, dust, and heavy metals.
Handle the product with care, avoiding any impact or friction that could compromise its stability.
