PPR (Polypropylene Random Copolymer) is formed by copolymerizing propylene and ethylene monomers
Unique molecular structure provides both rigidity and flexibility (Vicat softening point ≥131℃)
Enhanced heat resistance through antioxidants and thermal stabilizers

2. High-Temperature Impact Mechanism

Short-term exposure (below 95℃): Stable physical properties
Long-term exposure (above 70℃): Focus on creep resistance and oxidation degradation
Extreme temperature: Tolerates 110℃ briefly, continuous use below 95℃

3. Technical Advantages of IFAN PPR Pipes

Uses Borealis RA130E raw material (top global PPR resin)
Triple-layer co-extrusion structure (inner layer + reinforcing layer + outer layer)
Complies with ISO 15874 drinking water standard
50-year service life guarantee (based on EN 805)

4. High-Temperature Performance Comparison

Test Item	IFAN PPR Pipe	Standard PPR Pipe	Metal Pipe
Long-Term Temp	70℃ @ 1.0MPa	60℃ @ 0.8MPa	120℃+
Short-Term Pressure	95℃ @ 1.5MPa	85℃ @ 1.2MPa	150℃+
Linear Expansion	0.15mm/m·℃	0.16mm/m·℃	0.012mm/m·℃

5. Installation Recommendations

Use matching ifan PPR fusion fittings (ensure welding depth)
Install fixed brackets every 3 meters on straight sections
Install automatic air vents at system apex
Recommend water temperature ≤70℃ for continuous use

6. Typical High-Temperature Applications

Central heating systems (70-80℃ hot water)
Solar thermal systems (tank to collector sections)
Industrial cooling systems (≤95℃ heat transfer media)
Underfloor heating (≤60℃ supply water)

7. Advantages Over Other High-Temp Pipes

Compared to copper: 40% cost reduction, no electrochemical corrosion
Compared to PB: 25% higher pressure resistance, better creep resistance
Compared to PE-RT: 30℃ higher long-term heat resistance

8. IFAN’s Quality Assurance

100% hydrostatic testing for every batch
Free thermal expansion calculation service
Custom high-temperature piping solutions
Nationwide 24-hour technical support

What Makes PPH Ideal for Wastewater Systems?

During a chemical plant wastewater system upgrade, I recommended PPH pipes where stainless steel had failed in just two years. Five years later, the PPH system shows no signs of deterioration, demonstrating how this material excels in aggressive wastewater environments where metals often fail prematurely. PPH (polypropylene homopolymer) excels in wastewater applications due to its

Does PPH Maintain Stability in High Temperatures?

While working on a chemical processing plant’s hot effluent system, I specified PPH piping that has now operated continuously at 85°C for over eight years without failure. This real-world performance demonstrates PPH’s exceptional thermal stability when properly selected and installed. Yes, PPH (polypropylene homopolymer) maintains excellent stability at high temperatures, with continuous service ratings of

How Durable Are PPH Fittings in Harsh Environments?

I recently inspected a chemical processing plant where PPH fittings had served flawlessly for 15 years in acid exposure that destroyed metal components within months. This real-world validation demonstrated why PPH has become the preferred choice for aggressive industrial applications. PPH (Polypropylene Homopolymer) fittings demonstrate exceptional durability in harsh environments due to their superior chemical
