Plastic spool manufacturers: The difference between ABS and PS plastic spools.
PS plastic spools (polystyrene) have the following material characteristics: excellent electrical insulation (especially high-frequency insulation), colorless and transparent, with light transmittance second only to acrylic, can be colored, has water resistance, and good chemical stability. The strength is normal, but the quality is relatively brittle, making it prone to stress brittleness, and it is not resistant to organic solvents such as benzene and gasoline. Manufacturers of plastic spools are suitable for producing insulating transparent parts, decorative parts, chemical instruments, optical instruments, and other components. Molding performance: 1: Amorphous material, low moisture absorption rate, does not require complete drying, not easy to decompose, but has a large thermal expansion coefficient, making it easy to generate internal stress.

PSPlastic spool (polystyrene), material characteristics: excellent electrical insulation (especially high-frequency insulation), colorless and transparent, light transmittance second only to acrylic, coloring, water resistance, and good chemical stability. The strength is normal, but the quality is relatively brittle, prone to stress brittleness, and not resistant to organic solvents such as benzene and gasoline. Plastic spool manufacturers are suitable for producing insulating transparent parts, decorative parts, chemical instruments, optical instruments, and other parts.
Molding performance:
1Amorphous material, low moisture absorption, does not require complete drying, not easy to decompose, but has a large thermal expansion coefficient, easily generates internal stress. It has good fluidity and can be molded by screw or plunger injection machines.
2It is recommended to use a higher material temperature, higher mold temperature, and lower injection pressure. Extending the injection time is beneficial to reduce internal stress and prevent shrinkage and deformation.
3Various types of gates can be used, and the gate is connected to the plastic part with an arc to avoid damaging the plastic part when removing the gate. The demolding angle is large, and the ejection is uniform. The wall thickness of the plastic part is uniform, and it is best to have no inserts. If there are inserts, the plastic spool manufacturer should preheat them.
ABSSpool (Acrylonitrile-Butadiene-Styrene), light yellow granular or bead-like opaque resin, non-toxic, odorless, low water absorption. It has excellent physical and mechanical properties, outstanding low-temperature impact resistance, excellent electrical performance, wear resistance, dimensional stability, chemical resistance, and dyeability. It is easy to process and mold.ABSWater-resistant, inorganic salts, alkalis, and acids. It is insoluble in most alcohols and hydrocarbon solvents but easily soluble in aldehydes, ketones, esters, and certain chlorinated hydrocarbons.
ABSThe disadvantages are flammability, low heat distortion temperature, and poor weather resistance.
Burning characteristics: flammable; easily ignitable. Burning away from the fire source; Yellow flame, thick black smoke; Softening, bubbling; Acrylonitrile odor.
Solubility: Soluble solvent: dichloromethane; Insoluble solvents: alcohols, aliphatic hydrocarbons, water,
Applications: Plastic spool manufacturers in the automotive industry, machinery, electronics, and electrical appliances.
