High Strength and Impact Resistance of PC Endurance Panels: Explained with Concrete Examples

I. First, Understanding "Impact Resistance": What Makes It "Unbreakable"?

1. Laboratory-Grade Impact Tests: Data Speaks for Durability

• Test Conditions: Use a 6mm-thick PC endurance panel (a common thickness for outdoor use). A 3kg steel hammer (equivalent to the weight of a full 1.5L water bottle) is dropped freely onto the center of the panel from a height of 2 meters.
• Test Results: After impact, the panel only shows a temporary "dent deformation" but bounces back immediately—no cracks, no breakage. By contrast:
  • Tempered glass of the same thickness would shatter completely (even though tempered glass breaks into small granular pieces, it still poses a scattering risk).
  • Acrylic (PMMA) panels of the same thickness would develop obvious cracks or even snap.
• Data Comparison: Official data confirms that, at the same thickness, PC endurance panels have 250–300 times the impact resistance of ordinary glass and 30 times that of acrylic. To break a PC panel, you would need an impact force equivalent to "dropping a 100kg weight from 3 meters"—a scenario almost impossible in daily use.

2. Real-World Applications: "Fault Tolerance" Against Accidental Impacts

Scenario 1: Outdoor Canopies (Rain Shelters/Carports)

• Ordinary glass canopies: Most likely shatter immediately, with fragments endangering pedestrians or vehicles below.
• PC endurance panel canopies: Only leave slight impact marks; the panel remains intact, eliminating safety hazards.
  
  
  Many residential communities and shopping malls in China have replaced glass with PC panels for outdoor carports, specifically to withstand "accidental falling object impacts" during typhoons or downpours.

Scenario 2: Protective Panels for Children’s Playgrounds

• PC endurance panels: Even if a child accidentally crashes into the panel (impact force of 10–20kg) or a toy (e.g., plastic slides, balls) hits it at high speed, the panel never breaks.
• Glass or acrylic panels: Prone to cracks after long-term impacts, risking fragmentation.

II. Next, Understanding "High Strength": Focus on "Long-Term Load-Bearing" and "Pressure Resistance"

1. Load-Bearing Tests in Construction: Stability Under Long-Term Pressure

• Test Scenario: Take a 1.2m × 2.4m PC endurance panel (6mm thick), fix its two ends with metal frames (simulating the top support of an outdoor sunroom), and place sandbags totaling 50kg (equivalent to the weight of two adults) evenly on the center of the panel.
• Test Results: The panel bends slightly downward (deflection of about 2–3cm) but remains crack-free and without permanent deformation after 24 hours. When the sandbags are removed, it returns to flatness immediately. By contrast:
  • Tempered glass of the same size may withstand short-term pressure but is prone to "stress concentration" under long-term loads (e.g., accumulated snow), leading to sudden shattering.

2. Real-World Applications: Durability Against "Long-Term External Forces"

Scenario 1: Greenhouse Roofs

• Ordinary glass or plastic film greenhouses: Thick snow easily crushes the glass or tears the film.
• PC endurance panel greenhouses: The panels withstand long-term snow pressure without damage. After the snow melts, there is no deformation, and their service life reaches 10–15 years (compared to 2–3 years for film and frequent glass replacement due to temperature-induced cracking).

Scenario 2: Anti-Riot Shields for Highways

• If a  vehicle crashes into the shield (impact force of several hundred kilograms), the shield absorbs energy through deformation, avoiding fragmentation and injury to the user.
• Metal shields, though unbreakable, are much heavier (PC shields weigh only 1/3 of metal ones) and may cause rebound force during impact, which could harm the user.

Conclusion: The Core Value of PC Endurance Panels’ "High Strength + Impact Resistance"

• Safety-focused scenarios: Anti-riot shields, glass curtain walls in kindergartens, balcony guardrails.
• Durability-focused scenarios: Outdoor canopies, greenhouses, highway sound barriers.
• Lightweight-focused scenarios: Drone cabin covers, sports helmet visors (lightweight, no impact on operation).
