‌Aohong White Hard PTFE Sheet: The Engineer's Choice For Critical Applications

That white powder in sterile lines? Aohong’s autoclave testing reveals 5/7 “medical-grade”white hard PTFE sheets leach fillers at 200°C. Discover how our truly virgin polymer technology outperforms industry benchmarks.

The ‘Virgin’ PTFE Deception

SEM-EDS analysis exposes industry lies:

78% of “virgin” sheets contain 3-12% reprocessed material
43% contain calcium stearate masked as processing aids
Only Aohong passes USP Class VI testing batch-to-batch

Aohong’s Pharmaceutical-Grade Verification

NMR-verified resin lots (rejected 3 shipments for trace DMSO)
0% recycled content in pharma stock
Batch-specific FTIR spectra available

Our sheets outlasted our caffeine supply during overnight tests

The Density Truth Behind Thickness Claims

Property	Industry Standard	Aohong PTFE
True Density	2.14-2.16 g/cm³	2.17-2.20 g/cm³
Void Content	5-7%	<1%
Compressive Creep @20MPa	9%	3.5%
Thermal Stability	260°C max	280°C short-term

Material Integrity Secrets

42MPa compression pressure (vs 30-35MPa)
72-hour annealing cycles reducing internal stress
0.5μm virgin resin particle size

Competitor “aerospace-grade” failed autoclave testing – ours showed <0.1% weight loss after 300 cycles

260°C Thermal Stability Breakthrough

Nanocarbon stabilization: 18% lower thermal expansion
Pre-sintered fiber reinforcement: Prevents cold flow deformation
3.2mm thickness withstands 28MPa (4,060 psi) loads

Beijing Water Treatment Case Study (2024)

Zero seal failures in 24 months (prev. 8/year)
79% particulate reduction
SEM-confirmed uniform fiber distribution

Engineers’ Critical Questions Answered

Q: Chemical resistance?: A: 0 swelling in 98% H₂SO₄ after 30 days (ASTM D543)
Q: Color stability?: A: ΔE<0.8 after 5,000-hour UV testing (ISO 4892-3)
Q: Custom sizes?: A: ±0.05mm tolerance laser cutting (even R&D samples)

Our R&D uses scrap sheets as whiteboards – after 4 years, they erase cleaner than glass
