OP ExpertIn the composite materials, polymer processing, and rubber industries, selecting the right organic peroxide is a critical step in achieving consistent curing performance, production efficiency, and final product quality.
Many customers often ask:
● Which Nouryon peroxide grade is suitable for FRP resin curing?
● What is the difference between Butanox®, Trigonox®, and Perkadox®?
●Which peroxide should be selected for polymer crosslinking or rubber applications?
The answer depends on multiple factors, including resin type, processing temperature, curing speed, production method, and final performance requirements.
As a professional supplier of chemical raw materials, Evergreen Chemicals provides a comprehensive range of Nouryon organic peroxide solutions, including Butanox®, Trigonox®, Perkadox®, and Laurox® series, supporting customers in composite materials, plastics, elastomers, and polymer industries.
This guide provides a practical selection reference to help manufacturers choose the most suitable Nouryon organic peroxide for their applications.
1.How to Select the Right Nouryon Organic Peroxide?
Organic peroxide selection should not be based only on product name or price. The correct grade should be determined according to the following factors:
| Selection Factor | Influence on Product Selection |
|---|---|
| Resin or polymer type | Determines the suitable peroxide chemistry |
| Processing temperature | Affects peroxide decomposition behavior and curing efficiency |
| Manufacturing process | Different requirements for hand lay-up, filament winding, pultrusion, extrusion, and injection molding |
| Required curing speed | Influences production cycle time and productivity |
| Final product performance | Determines requirements for mechanical strength, heat resistance, and durability |
2.Butanox® Series Selection Guide
MEKP Curing Agents for Unsaturated Polyester Resin and FRP Applications
The Butanox® series is one of the most widely used methyl ethyl ketone peroxide (MEKP) curing agent ranges for unsaturated polyester resin (UPR) systems.
It is commonly applied in:
● Fiberglass reinforced plastic (FRP) tanks
● FRP pipes
● Marine composites
● Chemical equipment
● Pultruded profiles
● Artificial stone
● General composite manufacturing

Ava’s Final Advice: Selecting the Right Peroxide Requires Technical EvaluationFrom my experience working with composite and polymer manufacturers, the best peroxide solution is not always the fastest curing grade or the lowest-cost option.
A professional selection process should include:
| Step | Technical Evaluation |
|---|---|
| Step 1 | Identify the resin or polymer system |
| Step 2 | Confirm processing temperature and curing conditions |
| Step 3 | Evaluate production method and cycle requirements |
| Step 4 | Select peroxide grade according to decomposition characteristics |
| Step 5 | Conduct laboratory and production trials before final approval |
