DAIKIN polymer processing aids (PPA) are additives that enhance productivity by reducing melt fracture and die build-up when molding polyolefin resins.

DAIKIN supplies traditional PPA’s, and now hydrocarbon-based PPA’s with the launch of DAIKIN PPA DAHC-101. DAHC-101 provides performance levels comparable to traditional aids, allowing users greater flexibility in meeting their additive needs.

 Polymer processing aids (PPA), when added to general-purpose resins, reduce melt fracture, an unintended effect that causes defects during blown and cast film extrusion. Reduction of melt fracture (MF), in turn, enhances productivity and lowers production cost.

- DAHC-101, by reducing extrusion pressure, also enhances productivity and reduces production cost.

- DAHC-101 is a 100% hydrocarbon based polymer.
- DAHC-101 was developed as a processing aid for a broad range of for polyolefin resins, such as LLDPE, LDPE, HDPE, and PP.
- Adding DAHC-101 to polyolefin resins of 500-1,000 ppm provides a lubricious coating to the inner wall of the die, thus reducing friction between the molten polyolefin resin and the die wall, which then, minimizes melt fracture (MF) and die build-up (DBU).

(1) Reduction of melt fracture (MF)

DAHC-101 reduces melt fracture (MF), enhancing the gloss and transparency of molded products.

(2) Suppression of die build-up (DBU)

DBU causes deterioration to the surface quality of extruded films. Adding DAHC-101 suppresses DBU and improves extrudability.

Applications: Blown film, cast film, pipe, tubes, wire, cable
Resins: Polyolefin resins, such as polyethylene (LLDPE, HDPE) and polypropylene

DAHC-101 complies with the following food contact regulations:
