The key difference between PE white masterbatch and PP white masterbatch lies in their carrier resins: PE masterbatch uses polyethylene (PE) as the base, while PP masterbatch uses polypropylene (PP). This difference in carrier resin impacts the masterbatch's compatibility with different base polymers and its suitability for various applications.
PE White Masterbatch
- Carrier Resin: Polyethylene (PE), available in LDPE (low-density) and HDPE (high-density) forms.
- Applications: Best suited for flexible packaging, films, and products where flexibility is needed, such as shopping bags and some types of packaging.
- Key Feature: PE masterbatches are known for their versatility and compatibility with a wide range of polymers.
PP White Masterbatch
- Carrier Resin: Polypropylene (PP).
- Applications: Ideal for rigid containers, sheets, and fibers, as well as applications requiring heat resistance and chemical resistance, like woven sacks and some automotive parts.
- Key Feature: PP masterbatches offer good stiffness, heat resistance, and chemical resistance.
In Essence
- Choose PE white masterbatch when working with flexible polyethylene-based products.
- Choose PP white masterbatch when working with rigid polypropylene-based products or when heat and chemical resistance are important.
