EPS
Overview
Cheil Industries Inc. produce a EPS(expandable polystyrene) which is composited of polystyrene and blowing agents. starex EPS is lightweight with good thermal insulation, high strength and processability. These advantages allow its wide use in thermal insulating materials, packaging materials, food containers and other special purpose materials, through the process of pre-expansion, maturity and molding. The types of starex EPS can be classified into flame retardant, general, low pentane and other categories.
Features
1) Structure
The expanded bead of starex EPS has myriad cells when observed through a microscope. Each cell contains 50~100 cell/§± with polygon shapes. The cell size has a range of 0.01~0.02§®. This cell is an important factor in determining the mechanical properties and the quality of final products.
2) High Productivity and Good Processability
starex EPS has a short molding time with minimum utility, which significantly contributes to productivity improvements and economic efficiency. Due to its high expandability and moldability, high quality products can be easily manufactured.
3) Intensive Quality Control
To produce EPS of excellent quality, Cheil Industries Inc. is increasing its quality control efforts. Uniform grain size and stabilized qualities will offer many more benefits to users.
4) Various Applications
Various grades will meet the user's specific application requirements.
Properties
1) Thermal Conductivity
Due to low thermal conductivity, starex EPS is a valuable insulting material with very low density.
2) Strength and Durability
Since products made from starex EPS have a good mechanical strength, chemical resistance and dimensional stability, the ultimate performance is guaranteed in terms of strength and durability.
