It will be affected by following factors: 1. Humidity 2. Recycle material property 3. Storage condition
B: barrel temperature
Highest temperature: 230
Lowest temperature; 190
C: mould temperature 30-70°C
It will be changed by following factors: 1. Product thickness, 2. Size 3. Gate and hot runner system
ABS RESIN
ABS is a copolymer of Acrylonitrile, Butadiene, and Styrene, Its heat-resistance and solvent-resistance are better than HIPS. Besides, it has glass. Due to the stronger Cyantic polAcrylonitrile,themutual action of the PS molecule chain is streng then up. Therefore, the impact strength, the tensile strength and the surface hardness of ABS are better than HIPS.
Generally, the higher percentage of Acrylonitrile, the better the heat-resistance, rigidity and solvent-resistance, however, the worse the flow character; the base color of the plastic is a little yellow, but while injection mold, its mechanical and size stability are very good. Due to the above advantages, ABS resin becomes an excellent engineering plastic.
