The Last Solutions, Driving Innovation Beyond Boundaries
CL PP Series Peroxide M/B
Peroxide Masterbatch
CR PP series
Designed as a high-performance MFR (MI) modifier for polypropylene, CR PP Series is widely utilized in GMT, LFT, PP fibers, MAH-grafting, and PP recycling. Unlike liquid peroxides, this pelletized solution ensures accurate dosing while significantly enhancing safety and storage stability. Furthermore, unlike liquid peroxides which are classified as dangerous goods, CR PP Series is non-regulated. This allows for significantly simpler and more economical transport and storage.

Advantage
Advantages of CR PP Series over Liquid Peroxide
Safety
Classified as a non-hazardous material, with no restrictions on
storage or transport.
Ease of Use
Convenient to handle in solid pellet masterbatch form.
Homogeneous Dispersion
Excellent dispersibility in pre-dispersed PP extrusion pellets.
Accurate Content
Provides consistent flow with a narrow molecular weight distribution.
Easy MI Control
Precise control of physical properties is achievable through adjustable dosing
Comparison of Peroxide Types
Liquid PP
- Requires costly equipment
- High explosion and fire risk
- Hard to store (classified as hazardous)
- Inaccurate dosing
- Poor dispersion
Inorganic Filler-Based
- 30–50% peroxide in inorganic filler
- Powder form
- May include hazardous or unnecessary additives
- Possible negative interaction with filler
PP Flake-Based
- Accurate dosing
- Easier to handle than liquid type
- Possible uneven concentration or evaporation
- Risk of separation during premix
Masterbatch Type (CR PP Series)
- Used like standard masterbatch
- Not hazardous
- Highly accurate dosing
- Excellent dispersion
- Longer shelf life
