Anti-Scratch Masterbatch for Polypropylene
Masterbatch ASC: Batches for Anti-Scratch and Surface Enhancement
The Masterbatch ASC is used to improve the surface quality of PP while simultaneously increasing scratch resistance.
To achieve this, it contains a highly effective organically modified siloxane additive. This additive creates a thin film on the surface of the finished part, which bonds with the inner solid to form a unified unit. Special features of this particular film include its non-migratory nature, reduction of surface friction, and enhancement of the scratch resistance properties of PP.
Benefits of the Anti-Scratch Masterbatch ASC:
- Highly effective and permanent anti-scratch and surface enhancement
- Good scratch resistance properties despite aging
- No migration
- Anti-fog and odorless
- No influence on subsequent surface treatments such as coating, printing, or labeling
- Non-agglomerating pellets, free-flowing granules, and dust-free
- Improved processing and flow properties
- Enhanced demolding
- Safe and easy handling

By adding the Anti-Scratch Masterbatch ASC, the scratch resistance of PP plastic components can be increased (Figure 3).
