There are also two main processes for EPS molding:
1) One-step extrusion route, which is directly hot-extruded after EPS particles are foamed. This method is mostly used to manufacture sheets and films;
2)Air (or water vapor) at 100°C is pre-foamed 30-50 times, and then left for 24 hours to mature, and then the matured pre-foamed material is placed in a mold made of aluminum or castings, and 115-120 The air (or water vapor) at ℃ is heated, and while the material expands, the surfaces of the particles fuse with each other to form a foam plastic part by the action of heat.
Storage and Transportation
EPS products are generally safe and non-toxic, but raw materials in different states during processing have certain dangers. Polystyrene powder can irritate the respiratory tract and skin. EPS particles in storage emit vapors of pentane, which is extremely flammable and can form explosive mixtures with air. Heating polystyrene-based polymers may release styrene monomer, which is a hazardous substance.
Expanded polystyrene beans for bean bag has the advantages of low relative density (1.05g/cm3), low thermal conductivity, low water absorption, shock and vibration resistance, heat insulation, sound insulation, moisture resistance, vibration reduction, and excellent dielectric properties. It is widely used in Shockproof packaging materials for mechanical equipment, instruments, household appliances, handicrafts and other fragile and valuable products, as well as fast food packaging.
