とは PARALOID™ K-120ND Acrylic Processing Aid?
Readily dispersible acrylic processing aid powder is designed to improve the processing of rigid and flexible vinyl (PVC), allowing compounds to fuse rapidly, flow smoothly, have excellent hot metal strength, and improved surface appearance.
用途
- Specialty injection molding
- Vinyl applications that require critical rheological properties
- Blow-molding bottles
- Rigid and flexible calendered film
- Extruded construction products
- Blown or extruded vinyl film
- Packaging film
- Rigid containers
- Technical film
- Fence, deck and rail
- PVC plastics
- Siding
- Window frames/profiles
- Finished parts
- Foam modified for the industry standard of foamed PVC
- Used in cellular PVC to raise melt strength and impart lubricity during extrusion
- For use as an impact modifier for high output profile extrusion
- Foam core pipes
- Foam profile formulations
