Product Introduction

Bead Method Insulation Board Type 1 (EPS)

Features of Bead Method Insulation Board Type 1

This product is made by pre-heating bead raw materials to cause primary expansion, allowing them to mature for a suitable period, then filling them into panel-shaped molds, and finally heating again to cause secondary expansion and fusion molding.
Its formal name is Expanded Polystyrene (EPS), and terms like Styrofoam, Styrol, and Styropor are trademark names.

Advantages and Disadvantages of Bead Method Insulation Board Type 1

  • 01

    Easy to process on-site and minimal thermal performance variance depending on the construction method.

  • 02

    Excellent impact resistance and cost-effective.

  • 03

    High absorption rate, leading to decreased insulation performance when absorbing moisture.

  • 04

    Vulnerable to heat and prone to deformation, weak against chemical substances.
