Technical data and applications

 

Solef® 11010 PVDF

Solef® 11010 PVDF is a typical thermoplastic material that is used as an additive to give polymer resins unique benefits, such as eliminating melt cracking and reducing mold scale.
Due to its incompatibility with most polymers and its fast flow in the melt during extrusion, Solef® 11010 PVDF forms a thin coating on the metal surface of the mold, which directly improves the processability of the extruded polymer (stabilization of unstable flows). 

Key features:

1. Elimination of melt rupture (sharkskin phenomenon)
2. Reduced mold scale
3. Improve surface finish to achieve high gloss
4. Faster production start-up
5. Reduce pressure
6. Higher output under the condition of molding and temperature constan
7. Lower energy consumption

These benefits are typically achieved with Solef® 11010 PVDF at a final concentration of 200-1000



 

1. Original polymer pressure curve
2. Add additives to the polymer-lubricant, the pressure is reduced
3. Maximum yield of virgin polymer without melt rupture
4. By adding a base polymer (200ppm processing aid), the yield is significantly increased without melt rupture

apply
