(EPS) is a lightweight and rigid foam material. It is a material of choice for the packaging and construction industry. It provides cost-effective solutions and energy-efficient insulation. It also acts as a cushion transport packaging material for shock-sensitive goods.

 

1. What is expanded polystyrene (EPS)?

Expanded PolyStyrene (EPS) is a white foam plastic material. It is produced from solid beads of polystyrene. It is used for packaging and construction. It is a closed-cell, rigid foam material.

 

2. How is expanded polystyrene made?

Pre-expansion, Maturing/Stabilization, and Molding

Polystyrene is produced from crude oil refinery product styrene. For manufacturing EPS, the polystyrene beads are impregnated with the foaming agent pentane. Polystyrene granulate is prefoamed at temperatures above 90 degree .

This temperature causes the foaming agent to evaporate. Hence inflating the thermoplastic base material to 20-50 times its original size.

After this, the beads are stored for 6-12 hrs allowing them to reach equilibrium. Then beads are conveyed to the mold to produce forms suited as per application.

 

3. What are the fetures of EPS?

– Flexible production makes EPS versatile in strength. This strength can be adjusted to suit specific applications. EPS with high compressive strength is used for heavy load-bearing applications. For void-forming EPS, lower compressive strength can be used.

– The dielectric strength of EPS is approximately 2KV/mm. Its dielectric constant is measured in the frequency range of 100-400 MHZ. At gross densities from 20-40 kg/m3 the dielectric constant lies between 1.02-1.04. Molded EPS can be treated with antistatic agents to comply with electronic industry and military packaging specifications.
