PC Flame-Retardant Sheet Technology Breakthrough Empowers Fire Safety Upgrade: Baoding Xinhai Creates High-Performance Flame-Retardant PC Sheet Products

With continuously rising fire safety awareness and increasingly strict building fire protection standards, PC flame-retardant sheet application demand in the construction field continues to grow. Baoding Xinhai Plastic Sheet Co., Ltd. has successfully developed a series of high-performance flame-retardant PC sheet products through technological innovation, providing new material solutions for building fire safety.

**Flame-Retardant PC Sheets Become New Choice for Building Fire Protection**

Traditional building materials often become media for fire spread during fires, causing serious casualties and property losses. PC flame-retardant sheets, through special process treatment, possess good fire and flame-retardant properties while maintaining excellent physical performance, becoming a new choice in the building fire protection field.

PC flame-retardant sheets uniformly integrate flame retardants into the sheet substrate through co-extrusion technology, achieving B1-level flame retardant requirements in the GB8624-97 standard. B1-level flame retardancy means the material does not produce melt droplets during combustion, and the burning speed is significantly lower than ordinary plastics, meeting stringent building fire safety requirements for public buildings.

Baoding Xinhai Plastic Sheet Co., Ltd.'s flame-retardant PC sheets have a self-ignition temperature as high as 580°C, self-extinguishing when removed from fire, and do not produce toxic gases during combustion, not promoting fire spread. This characteristic makes them particularly suitable for lighting skylights and partition walls in crowded places such as shopping malls, sports venues, stations, and airports.

**Technological Innovation Enhances Flame-Retardant Performance**

The flame-retardant performance of PC flame-retardant sheets derives from the material's molecular structure design. Traditional flame-retardant methods involve adding flame retardants during the production process, but this method has problems such as flame retardant migration and precipitation, affecting product performance durability.

Baoding Xinhai adopts advanced co-extrusion technology, uniformly integrating flame retardants into the sheet surface layer, forming chemical bonds with the substrate to ensure long-term stability of flame-retardant performance. Testing shows that after 5,000 hours of artificial aging tests, the company's flame-retardant PC sheets still maintain stable flame-retardant performance.

Additionally, the company is developing a new generation of high-efficiency flame-retardant PC sheets, planning to introduce more advanced flame-retardant technology to further enhance product fire safety performance. New products are expected to be launched in the second half of 2026.

**Multi-Scenario Applications Improve Building Safety Levels**

PC flame-retardant sheets, with their excellent comprehensive performance, play important fire safety roles in multiple building application scenarios.

In commercial complexes, PC flame-retardant sheets are commonly used for atrium lighting skylights and indoor pedestrian street canopies. Their high light transmittance can effectively utilize natural light for illumination, reducing lighting energy consumption; meanwhile, excellent flame-retardant performance can effectively prevent fire spread, ensuring safe personnel evacuation.

In transportation hubs, PC flame-retardant sheets are extensively used for lighting canopies in airport terminals and railway station platforms. Their lightweight and high-strength characteristics can reduce steel structure load, weather resistance can adapt to various climate conditions, and flame-retardant performance provides protection for public safety.

In industrial plants, PC flame-retardant sheets are used for roof lighting and wall lighting, meeting lighting needs while improving plant fire safety levels. They are particularly suitable for Class C and D industrial buildings with higher fire protection requirements.

**Integration with Intelligent Fire Protection Systems**

Modern building fire protection has shifted from passive fire prevention to active prevention and control, with intelligent fire protection systems gaining increasingly widespread application. PC flame-retardant sheets can integrate with intelligent fire protection systems to further enhance building fire safety levels.

Baoding Xinhai is developing intelligent flame-retardant PC sheets with reserved installation interfaces for smoke sensors and temperature sensors, able to interface with building fire control systems. When fire situations occur near the sheets, sensors can promptly detect and send signals to the control system, achieving early warning and rapid response.

The company's technical director stated that intelligent fire protection is the future direction of building fire protection development, and as building enclosure materials, PC sheets also need to adapt to this trend. Baoding Xinhai will continue to advance product intelligentization upgrades, contributing to building fire safety.

**Strict Quality Control Ensures Product Performance**

Baoding Xinhai Plastic Sheet Co., Ltd. has established a comprehensive quality management system, strictly controlling the entire flame-retardant PC sheet production process. From raw material incoming inspection, to production process key procedure monitoring, to finished product performance testing, every aspect has clear inspection standards and records.

The company has a professional testing laboratory equipped with professional testing equipment including oxygen index testers, combustion testing machines, and aging test chambers, able to comprehensively test product flame-retardant performance, mechanical properties, and weather resistance, ensuring every batch of factory products meets quality requirements.
