PP Flame-retardant Plastic Board

PP Flame-retardant Plastic Board

PP flame-retardant plastic sheet（PP Flame-Retardant Plastic Board） is a functional engineering plastic sheet made from polypropylene (PP) as the base material. It is produced by adding efficient and environmentally friendly flame-retardants (such as bromine-based, phosphorus-nitrogen-based or halogen-free expanded flame-retardants, etc.) through blending modification, melt extrusion, and calendering molding processes. Its core feature is that it retains the advantages of lightweight, corrosion resistance, and easy processing of PP materials while significantly enhancing the flame-retardant performance, meeting the strict requirements for fire safety in various scenarios, and is widely used in the fields of chemical industry, electronics, construction, and transportation.As a PP Sheet Supplier, we offer high-quality sheets that combine the lightweight, corrosion-resistant, and easy-to-process characteristics of polypropylene with enhanced flame-retardant properties.

Product Advantages

1.Excellent flame-retardant properties

The flame retardant grade can reach UL94 V-0/V-2 (adjusted according to specific formulas), with an oxygen index (OI) of ≥28% (some high-end models can reach over 35%), and the self-extinguishing time after being separated from the fire is short (≤3 seconds), effectively suppressing the spread of flames.

2.Maintain the core advantages of the PP substrate

•Lightweight and high strength: The density is only 0.90 - 0.95 g/cm³ (approximately 1/8 of steel), making it extremely lightweight while maintaining stable mechanical strength. It has better impact resistance than common plastics (such as PVC).

•Chemical corrosion resistance: Exhibits excellent tolerance to acids (such as sulfuric acid and hydrochloric acid), bases (such as sodium hydroxide), salt solutions, and most organic solvents (such as alcohols and ketones), making it suitable for chemical storage and transportation scenarios.

• Excellent temperature resistance: The long-term operating temperature range is -20℃ to 120℃ (short-term it can withstand up to 140℃), and it retains its toughness even in low-temperature environments (the brittle point is approximately -35℃).

3.Easy processing and economy

• Supports conventional processing methods such as cutting, drilling, bending, hot welding, and bonding. It is also compatible with precision processing equipment like CNC machines and laser cutting machines, with strong adaptability.

The raw material cost is lower than that of engineering plastics (such as PC and POM), and the overall cost performance is excellent, making it suitable for large-scale applications.

4. Environmental Protection and Durability

• Tasteless and non-toxic (in compliance with food contact grade standard GB 4806.6-2016, optional), smooth and flat surface, excellent aging resistance (UV additive optional), long service life.

Scope of Use

1.Industrial sector

•Chemical equipment: As anti-corrosion linings, reactor cover plates, and insulation outer covers for pipelines, they can resist acid and alkali corrosion as well as fire risks.

•Electroplating / Environmental Protection Equipment: Used for the side panels of electroplating tanks and the cover plates of wastewater treatment ponds, resistant to chemical media and flame retardant.

•Mechanical protection: Machine guard, equipment enclosure, operation console panel, anti-static (optional) + dual protection of flame retardancy.

2.Electrical and Electronic Field

•Distribution cabinet / control box: Internal partitions, insulating supports, meet UL94 flame retardant requirements, reduce the risk of electrical fires.

•Battery pack / energy storage box: Battery module spacer, outer shell protective layer, resistant to electrolyte corrosion and flame retardant (suitable for new energy applications).

3.Architecture and Public Facilities

•Wall panels / partitions: Fireproof decorative panels (requiring surface coating treatment), lightweight alternatives to traditional stone / metal.

•Stair steps/platforms: Anti-slip, flame-retardant floor for public buildings, resistant to wear and fireproof.

•Subway/airport facilities: Cable trough covers, security check equipment fences, comply with fire resistance standards for public places.

4.Transportation

•Automobile/Railway Transportation: Interior components (such as dashboard brackets, luggage rack partitions), battery pack protective plates, lightweight and flame-retardant.

•Ship compartments: Crew activity areas, equipment hatch covers, resistant to salt spray corrosion and fireproof.
