Key Features of Polystyrene Foam Beads
Lightweight:
Extremely low density, making them ideal for producing lightweight foam products.
Expandable:
Contains a blowing agent that allows the beads to expand up to 50 times their original size when heated.
Thermal Insulation:
Excellent thermal insulation properties due to the closed-cell structure of the foam.
Shock Absorption:
Provides excellent cushioning and impact resistance, making it ideal for protective packaging.
Moisture Resistance:
Resistant to water absorption, making it suitable for humid environments.
Eco-Friendly:
100% recyclable and can be reused in the production of new EPS products.
Types of Polystyrene Foam Beads
Standard EPS Beads:
Used for general-purpose applications such as packaging and insulation.
Flame-Retardant EPS Beads:
Contains additives to improve fire resistance, commonly used in construction and insulation.
High-Strength EPS Beads:
Designed for applications requiring higher compressive strength, such as construction and load-bearing insulation.
Food-Grade EPS Beads:
Complies with food safety standards, used for producing food containers and packaging.
Applications of Polystyrene Foam Beads
Packaging:
Protective packaging for electronics, appliances, and fragile items.
Construction:
Insulation panels, lightweight concrete forms (ICF blocks), and decorative elements.
Food Industry:
Disposable food containers, cups, and trays.
Consumer Products:
Helmets, toys, and coolers.
Industrial:
Buoyancy aids, flotation devices, and insulation for pipelines.
EPS Manufacturing Process Using Polystyrene Foam Beads
Pre-Expansion:
Raw EPS beads are expanded using steam in a pre-expander machine. The heat causes the blowing agent to vaporize, expanding the beads.
Aging:
The expanded beads are stored to stabilize and allow air to permeate the beads.
Moulding:
The beads are fed into a moulding machine, where they are exposed to steam again. The beads expand further and fuse together, taking the shape of the mould.
Cooling:
The moulded product is cooled using water or air to solidify its shape.
Demoulding:
The finished product is removed from the mould, trimmed (if necessary), and prepared for packaging or further processing.
Advantages of Polystyrene Foam Beads
Lightweight:
Reduces transportation costs and makes handling easier.
Insulation Properties:
Excellent thermal and acoustic insulation.
Shock Absorption:
Ideal for protective packaging due to its cushioning properties.
Cost-Effective:
Low material and production costs.
Customizable:
Can be moulded into various shapes and sizes to meet specific requirements.
Eco-Friendly:
Recyclable and reusable, contributing to sustainability.
Storage and Handling of Polystyrene Foam Beads
Storage Conditions:
Store in a cool, dry place away from direct sunlight and heat sources.
Keep away from open flames or sparks, as the blowing agent is flammable.
Shelf Life:
Polystyrene foam beads have a long shelf life if stored properly.
Handling:
Handle with care to avoid damaging the beads.
Use appropriate personal protective equipment (PPE) when handling.
