Donna Polymer - Flame Retardant Sheet

Flame Retardant Sheet

YC-SG Series

Introduction

1. Mineral insulation cable based flame retardant mechanism.

2. The minimum sheet thickness: 0.3 mm

3. Poor tensile and tear resistance.

4. Self-adhesiveness: it can adhere to almost all kinds of materials.

5. Excellent thermal insulation properties: The temperature measured behind of a 0.5 mm thick YC-SG flame retardant sheet can 670~770°C lower than the source of fire (pls see Figure below). 6. Excellent fire protection effect: The wood material protected by 0.5 mm thick YC-SG flame retardant sheet will only be carbonised but not catch a fire.

Fire Protection Mechanism

When the temperature reaches above 150°C, the YC-SG begins to expand the volume due to the foaming reaction, consequently forming a thermal insulation layer to hinder the transfer of heat. Since the YC-SG contains a glassy component, the foamed shell layer will be softened at the temperature above 800 ~ 900°C and thereafter becomes deformable due to its volume expansion when heated. Thus, the heat insulation layer is possible to be held without collapsing.

Application

Suitable for fireproof wood-based construction materials, products, furniture and wallpaper as well as fireproof veneers, etc.

YC-NH Series

Introduction

1. Mineral insulation cable based flame retardant mechanism.

2. The minimum sheet thickness: 0.1 mm

3. Tensile and tear resistance: Excellent

4. Self-adhesiveness: No

5. Excellent thermal insulation properties: The temperature measured behind of a 0.5 mm thick YC-NH flame retardant sheet can 500~600°C lower than the source of fire (pls see Figure below) 6. Can be used in combination with YC-SG series

Fire Protection Mechanism

When the temperature reaches above 150°C, the YC-NH will undergo volume expansion caused by foaming reaction volume, forming a rigid heat insulation layer to hinder heat transmission. Because of the rigid heat insulation layer, when the temperature is above 800 ~ 900 ℃, the heat insulation layer will rupture. Consequently, the flame may penetrate the object to be protected and get ignited.
