Description
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.
2. Introduction to the grade of fireproof corflute sheets
(1) After two 10-second burning tests on the fireproof corrugated plastic hollow sheets, the flame goes out within 60 seconds. There may be hollow boards burning off, this is a V2 flame retardant hollow board.
(2) After two 10-second burning tests on the fireproof correx sheets, the flame goes out within 60 seconds. There can be no burning material falling from the hollow board, this is a V1 flame retardant hollow board.
(3) After two 10-second burning tests on the fireproof coroplast sheets, the flame goes out within 30 seconds. There can be no burning material falling from the hollow board. This is a V0-level flame-retardant coroplast sheet and the highest-level flame-retardant coroplast sheet.
3. Application of flame-retardant hollow board:
(1) Make backing plates in special environments, such as floor protection at the welding operation site, backing plates under the oven for printed products, and backing plates in new energy batteries
(2) Make a flame-retardant coroplast box to store products with special requirements.
(3) The current ventilation ducts of the farm are also made of flame-retardant hollow boards.
