EPS Resin Raw Material Expandable Polystyrene CAS 14235-54-2

Products Description

What is EPS resin raw material Expandable polystyrene CAS 14235-54-2 ?

Expandable polystyrene (EPS) is a white or colorless transparent bead (plural: beads) with controlled particle size. Its CAS number is 14235-54-2, chemical formula is (C₈H₈)ₙ (n = degree of polymerization), and molecular weight varies with polymerization. When heated to 90–110℃, it expands to 30–50 times its original volume, forming a closed-cell foam structure with low thermal conductivity, high elasticity, and shock resistance.
The production of expandable polystyrene uses styrene as the monomer, synthesizes polystyrene beads via suspension polymerization, and incorporates low-boiling hydrocarbons (e.g., pentane, butane) as blowing agents. Foam products are manufactured through pre-foaming (steam heating), aging (stabilizing cell structure), and molding (steam welding) processes.

Uses

Packaging materials
Expandable polystyrene is used for cushioning packaging of electronic equipment, precision instruments, food, etc., using its lightweight and shock-resistant properties to protect items from impact.
Building insulation
As an insulation material for walls, roofs, and floor heating, the thermal conductivity is as low as 0.033 W/(m·K), effectively reducing building energy consumption.
Decoration and model
Used to make advertising models, crafts, stage scenery, etc., easy to cut and shape and low cost.
Floating material
The density of foam products is lower than that of water, and can be used for life-saving equipment and floating balls.
