Scratch-free surfaces with anti-scratch masterbatch for polypropylene
Masterbatch ASC: Batches for Anti-Scratch and Surface Enhancement
Polypropylene (PP) impresses with its versatility – but its scratch resistance can quickly reach its limits. With special anti-scratch masterbatches from GODIPLAST, sensitive PP surfaces can be specifically optimized and made significantly more resistant – ideal for visible applications in the automotive and consumer goods sectors.
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
