Processing Aid-Masterbatches improve the result of your extrusion process, increase your output and decrease your energy consumption.
Processing aid for an increased extrusion output of filled and unfilled polyolefines with a simultaneous improvement of the surface of the product by avoiding melt fracture and fish-eyes.
CORDULEN ® Processing Aid-Masterbatches primary build up an inner coating of the metal-extruder- surfaces. The fluor polymer, used as lubricating substance, is very incompatible to the polymer melt and tends to migrate to the surface of the polymer even during the manufacturing process. The fluor polymer shows great affinity to metal surfaces. Thus, an extremely thin (molecular) fluor polymer-film - which is also extruded - between the extruder barrel respective the screw and the polymer melt, is built up. Comparable with a co-extrusion, a plastic extrudate with a polyolefin core and a fluor polymer surface is produced. This extremely thin fluor polymer surface maintains all polyolefine properties with an additional benefit of improved flow-properties.
Advantages, attained by CORDULEN ® Processing Aid-Masterbatches
The frictional resistance of the polymer melt in the extruder is reduced, the flowability of the melt grows
- reduced processing temperature
- reduced mass-pressure
- increased screw speed
- reduced speed differences = reduced melt fracture
-> Consequently the output as well as the take-off speed can be increased
- In contrast to usual slip agents, the final product can be coated, bonded, printed, welded or surface-treated with the Corona-procedure
- Filling materials, pigments, antiblock agents and slip agents practically show no influence
- Cleaning effect on the die during the production
- PE-LD, PE-HD, PE-LLD and Copolymers.
- PP-Homo, PP-Copo, PP-Random
- EVA, EBA
Food contact approval
In general, nearly all of the active agents are admitted within the usual dosage, according to the BfR-recommendations.
The particular data can be taken out of the product information sheets.
Approvals of other authorities, especially FDA- and EC-approvals are present in most cases and are available, if required.
