Product Properties: 

DB-650 is a polyolefin transparent agent, which can be used in polyethylene and polypropylene to regulate the crystallization behavior and greatly reduce the crystal size, thus reducing the haze and improving the transparency of products.DB-650 can also improve the gloss and thermal deformation temperature of polyolefin.

Applications:
Used in extrusion, injection molding, molding and other processes, like LLDPE and LDPE products; PP stationery; photoelectric protective film; PP/PE plastic bottle caps.

Method:
Dosage: 0.1%-0.4% to available optimum performance.

Mix dispersion:
Put DB-650 transparent agent and powder/granule together, and mixed at high speed, then pelleting.
At high speed mixing, a small amount of white mineral oil can be added to promote the bonding and dispersion of nucleating agent powder and polypropylene resin.
DB-650 transparent agent also can used in high-concentration masterbatch.

Extrusion granulation:
Granulation with twin screw extruder or single screw with high strength mixing capacity, good dispersion is helpful to improve the nucleation effect and physical properties of DB-650.
Process parameters according to the conventional polypropylene process Settings, don't need to do much adjustment, extrusion temperature suggested above 230 ºC.

Packing:  5kg/10kg bags, then package in carton.

Storage: Placed in dry, avoid light environment.
