Publish Time: 2018-10-12 Origin: Site
Blending modification refers to the blending of other plastics, rubber, or thermoplastic elastomers with PP and filling them into larger crystal spheres in PP to improve the toughness and low temperature brittleness of PP.
Example of blending modified formula
Raw material | Basic formula / portion | Raw material | Basic formula / portion | ||||
PP（ T30S） | 100 | PA6 (M2800) | 14 | ||||
PP-g-MAH | 6 | Nanometer CaCO3 | 12 | ||||
Processing: | |||||||
Temperature (unit: ℃) | Zone 1 | Zone 2 | Zone 3 | Zone 4 | Zone 5 | Zone 6 | Diehead |
175 | 185 | 190 | 210 | 225 | 235 | 215 | |
Attention: | |||||||
(1) PA6 was dried in 80 ℃ blast dryer for 8 h; (2) PP-g-MAH drying in 75 ℃ blast dryer for 4 h; (3) Mix evenly in high speed mixer according to formula weighing, then granulation by blending and extruding with twin-screw extruder. | |||||||
