    1. Introduction of fireproof coroplast corrugated plastic sheets

    (1)Flame-retardant coroplast sheets are also called fire-resistant/fireproof coroplast sheets/corrugated plastic sheets. It is a hollow board with flame-retardant effect by adding flame retardant to PP polypropylene raw material through extrusion molding. Usually, we can divide the flame-retardant corflute sheets into three grades, V2, V1 , V0. The flame-retardant coroplast sheets can extinguish automatically after leaving the fire source and will not become a fire-inducing material.

    (2)At the same time, other performance indexes of the fireproof corflute sheets must also meet the technical indexes of the ordinary corflute sheets.

    The flame-retardant hollow sheets have the characteristics of lightweight, non-toxic, non-polluting, waterproof, shockproof, anti-aging, corrosion resistance, and rich colors like ordinary pp hollow sheets. In addition, it has high flexural, aging, tensile, compression and tear strength, and colors and sizes are customizable according to needs.
