Product Description:
|
|
PS Filler Masterbatch is taken styrene as monomer and made of radical polymerization or ionic polymerization. Production Method has bulk polymerization,solution polymerization,suspension polymerization and emulsion polymerization,etc.Currently Industrial production is mainly adopted suspension polymerization and bulk polymerization.

Product features
|
PS filler masterbatch flow, processing performance is good, easy to color, size stability.Available for injection molding, extrusion, blow molding, foaming, thermoforming, adhesive, coating, welding, machining, printing methods such as processing into various parts, especially suitable for injection molding.When injection molding material generally without drying and used directly.But in order to improve the quality of products, can predrying 1-2 h in 55-70 ℃ drum wind drying oven .Roughly the specific processing conditions is : cylinder temperature about 200 ℃, 60-80 ℃ temperature of injection mold temperature 170-220 ℃, 60-150 mpa, the compression ratio of 1.6 to 1.6.After molding products in order to eliminate the internal stress, but in the infrared lamp or drum wind drying oven at 70 ℃ constant temperature processing 2-4 h.Extrusion molding, generally use the screw length to diameter ratio L/D for 17-24, For air cooling, extrusion temperature 150-200 ℃. Blow molding, injection molding and extrusion can be used to blow molding of parison with molding made the required product.Blowing pressure generally 0.1 0.3 MPa1.
