‌The PTFE Sheet That Actually Works

That white crust between your flanges signals PTFE degradation. Aohong’s testing reveals most “premium” sheets contain hidden fillers – we X-ray every 10th sheet to ensure 100% pure fluoropolymer performance.

The Density Deception in PTFE Sheets

Thickness alone lies – density determines real performance:

Material Type	Density Range	Composition
Standard Sheets	2.15-2.17 g/cm³	Voids + fillers
Aohong Reinforced PTFE	2.18-2.20 g/cm³	Solid polymer matrix

Shanghai Jiao Tong University verified our density claims (coffee stains prove HCl resistance!)

Performance Comparison: Industry vs Aohong

Scenario	Industry Standard	Aohong PTFE
Concentrated HCl (pH 0.5)	6 months	22 months
Thermal Shock Cycles (-70°C→288°C)	200	850+
Installation Misalignment Tolerance	2mm	5mm

3 Industry Secrets Competitors Hide

Precision Fiber Orientation
- 37° glass fiber angle (ASTM D638 verified)
- 28% better stress distribution
Uncompromising Purity Control
- Hourly melt flow index monitoring
- FTIR contaminant scanning
- 1,500 psi pressure test on every roll
Thermal Stabilization Breakthrough
- <2% crystallinity variation vs 5-8% industry standard

“73% fewer callouts since switching to Aohong – the only PTFE surviving our caustic soda spills.”
– Zhang, Shanghai Petrochemical Supervisor

Costly PTFE Installation Mistakes

Myth: Thickness = Performance
- 5mm void-filled sheet underperforms our 3.2mm solid material
Ignoring Thermal Expansion
- Standard: 120µm/m·°C at 288°C
- Aohong: <95µm/m·°C at 288°C
Using Generic Cutting Tools
- Requires carbide blades (specs included with every order)

Authenticity Check

Our matte finish indicates proper fiber integration – glossy surfaces reveal cheap compression molding.
