Tert-Butyl peroxy-3,5,5-trimethylhexanoate is a liquid peroxide ester compound with the characteristics of both peroxide ester and tert-butyl in its molecular structure.This makes its decomposition temperature between diacyl peroxide and 2-tert-butyl peroxide, making it a high performance medium temperature initiator.
The main product characteristics as below
Medium high temperature decomposition
10 hour half-life temperature is about 94℃. Its self accelerating decomposition temperature is about 50℃, and acid&alkali significantly increase its thermal hazard.
low odor
The decomposition products have a high molecular weight, not easily volatile, which can significantly reduce the odor of the final polymer products. It's suitable for food packaging, automotive interiors, etc.
Application
EVA foam and cross-linked products
When producing midsoles, yoga mats, and cable sheaths for sports shoes, their decomposition temperature matches well with the foaming agent, allowing for matrix cross-linking before foaming, resulting in products with uniform foam pores, good elasticity, and good resistance to compression and permanent deformation.
High performance acrylic resin and coatings
Can ensure pure color, good weather resistance, and low residual odor of the paint film, suitable for producing acrylic resin for automotive topcoat and high-end furniture coating
High temperature curing of composite materials
As a curing agent for unsaturated polyester, it is used in the production of automotive SMC components (such as bumpers, battery trays) and bathroom products. The temperature curing characteristics balance production efficiency and component strength, avoiding high temperature damage to glass fibers
Package & Storage
Package
25kg drum or 200kg drum.
Storage
Keep the container sealed.

FAQ
Q: What is the most striking characteristic of the peroxide?
A: Its most significant characteristic is the moderate decomposition temperature (the half-life temperature of 10 hours is about 72℃), which perfectly balances the reaction activity and operational safety, ensuring the stability at room temperature storage and efficient reaction at medium and high temperatures.
Q: Why was tert-Butyl peroxy-3,5,5-trimethylhexanoate selected as the crosslinking agent for EVA foam shoe material?
A: Its decomposition temperature and EVA foaming agent decomposition temperature cooperate with each other, which can complete the matrix crosslinking before foaming, forming a uniform closed cell structure, giving the shoe sole excellent rebound and durability.
Q: What are the advantages compared to benzoyl peroxide (BPO)?
A: The product does not turn yellow and the operation is safer and more convenient.
BPO contains benzene rings, which can easily cause products, especially light colored products, to turn yellow over time after decomposition. This product does not contain benzene rings, which fundamentally avoids this problem and can maintain the appearance of the product for a long time.
BPO is a solid powder that needs to be dissolved in advance, which poses a risk of dust and uneven mixing. This product is a ready to use liquid that can be directly pumped and accurately measured, making it easy to automate feeding and improving production efficiency as well as the working environment in the workshop.
