Tert-Amyl peroxy-2-ethylhexanoate is an organic peroxide and is mainly used as an initiator for free radical polymerization. Especially in the high pressure tubular process of producing polyethylene (LDPE), it has become a key chemical in this field due to its specific decomposition characteristics.
The main product characteristics as below
High efficiency triggered in medium - high temperature
Its 10 hour half-life temperature is 73℃, which determines that it has the best efficiency in the temperature range of 90-130℃.
Dual function of aggregation and solidification
It is an efficient free radical polymerization initiator,also works as a high-temperature curing agent for unsaturated polyester resins. It's widely used in the synthesis of plastic resins & the curing of composite materials and coatings, providing flexibility for formulation design.
Poor thermal stability
Self accelerating decomposition temperature is only 35℃.The cargo must be stored under 10℃.

Application
LDPE/EVA resin with high pressure producting tech
It is one of the important initiators in the production of LDPE/EVA resin, which helps to produce high-quality EVA resin with controllable molecular weight distribution and uniform VA content. Suitable for producing foam shoe materials, photovoltaic packaging adhesive films, hot melt adhesives, etc

Synthesis of high transparency resin
Good options for synthesis of high transparency/light colored resins such as optical/food grade PMMA, PS, ABS, etc
It can ensure the resin has excellent optical transparency and initial whiteness, meeting the appearance requirements of optical lenses, lampshades, and high gloss plastic parts.

High-temperature curing
At a molding temperature of 120-160 ℃, it can provide efficient curing rate, ensuring uniform internal and external curing of large or thick walled products, and obtaining high-strength, heat-resistant, and smooth surface finished products. Suitable for hot pressing and curing of fiberglass products (such as SMC/BMC molded automotive parts, electrical equipment casings) and artificial marble/quartz.

Package & Storage
Package
25kg drum,200kg drum or requirement of clients
Storage
Keep the container sealed.
Stored in a cool, dark and dry place, must be under 10℃.

FAQ
Q: What is the biggest risk of transportation and storage?
A: The biggest risk is that tert-Amyl peroxy-2-ethylhexanoate has the general properties of organic peroxide, which may self-accelerated decomposition when heated, impacted, rubbed or contacted with impurities, leading to fire or even explosion.
Q: Will there be any residue in the polymer? Will it affect product performance?
A: The fragments will remain in the polymer after decomposition, but with careful design, the amount of residue is very low and has no adverse effect on the performance of the final polyethylene product.
Q: What are the most important technical parameters when choosing to use it?
A: The most important technical parameter is the half-life, that is, the time it takes to decompose half at a given temperature, which directly determines the reaction temperature at which it is applicable.
