HDPE Flame-Retardant Board is a modified high-density polyethylene sheet engineered to provide reliable flame-retardant performance while maintaining the toughness, chemical resistance and processability of standard HDPE. It is widely used in environments where plastic materials must resist ignition, slow flame spread and maintain structural integrity under elevated temperatures.

1. Key Performance Features
- Effective flame-retardant performance
Produced with halogen-free flame retardants or custom FR formulations, the board can achieve common industry flame ratings such as UL94 V-0 / V-2 / HB depending on customer requirements. It delays ignition, reduces dripping and limits flame propagation. - Maintains HDPE toughness
Unlike many flame-retardant plastics that become brittle, FR-HDPE retains excellent impact resistance and flexibility, suitable for demanding installation or repeated mechanical stress. - Chemical & corrosion resistance
Resistant to acids, alkalis, salts and moisture, making it suitable for corrosive industrial environments and outdoor installations. - Low friction & wear resistance
Features a naturally low coefficient of friction and good sliding characteristics, suitable for components that require both flame-retardancy and wear resistance. - Electrical insulation
HDPE inherently provides strong dielectric properties and volume resistivity, making flame-retardant HDPE suitable for electrical cabinet lining, safety partitions and other protective structures. - Low water absorption & stable dimensions
Low moisture uptake ensures stable performance in humid or outdoor environments without swelling or deformation.
2. Advantages Compared with Standard HDPE
- Enhanced fire safety: Reduces ignition risk and limits damage in case of accidental fire.
- Better protection for electrical and industrial equipment: Suitable for applications requiring both insulation and flame retardancy.
- Better compliance: Helps meet safety standards in buildings, public facilities, chemical plants and transportation equipment.
- Customizable performance: Flame-retardancy level, color, surface texture, and anti-static properties can all be modified.
3. Typical Applications
- Electrical & power systems
Panels, protective covers, insulation plates and structural components inside electrical cabinets, switch rooms and substations. - Chemical & industrial plants
Flame-retardant partitions, safety shields, duct covers and anti-corrosion boards in areas exposed to acids, alkalis and chemicals. - Public facilities and transportation
Wall panels, protective boards and safety components where flame-retardant materials are required by regulation. - Machinery & equipment manufacturing
Wear-resistant and FR-safe components such as sliders, bushings, guards and covers. - Food, packaging & logistics
Non-toxic, low-absorption boards suitable for hygienic environments with elevated safety requirements.
4. Customization Options
HDPE flame-retardant boards can be manufactured according to customer specifications:
- Custom thickness, width and sheet size
