Why Choose PPH Filter Housing Over PP or UPVC Housing?

In industrial filtration systems, the material of a filter directly affects how stable and durable the equipment is. The three most commonly used plastic filters are PP, UPVC, and PPH. All three are corrosion-resistant, but they are very different in temperature resistance, strength, and long-term reliability. As industrial conditions get more demanding, PPH Plastic Filter Housings perform better overall and are becoming the top choice for many industries.

Brief Material Performance Comparison

PP (polypropylene) is a basic corrosion-resistant plastic. It resists acids and alkalis well and costs less. It works fine for normal temperature and low-pressure filtration. But it's not very strong and can't stand high temperature. It shouldn't be used over 60°C for long. It can easily warp or age with continuous use, making the filtration system unstable.

UPVC (unplasticized polyvinyl chloride) is more stable and stronger than regular PP. It's widely used in water treatment and general industrial filtration. But it can't handle high temperatures either - max long-term use is 45°C. Its service life drops a lot if temperatures change a lot or the liquid is highly corrosive.

PPH (homopolypropylene) is an upgraded version of PP with much better all-around performance. It's more stable in high temperature resistance, pressure resistance, and chemical corrosion resistance. It can work continuously at 80–90°C. Even in strong acids, strong alkalis, and complex chemical environments, it stays structurally intact. It's perfect for steady, long-term industrial use.

Application Advice

PP or UPVC filters work well for room-temperature water treatment, low-pressure filtration, or projects with a tight budget. But PPH filter housings are much better for these industrial situations:

● Filtration where temperature stays above 50°C

● Industrial use that requires high safety and reliability

● Filtration with strong acids, strong alkalis, or complex chemicals

● Production that needs stable long term running and less maintenance

In these conditions, PP and UPVC filter housings easily age, warp, and wear out faster, which raises maintenance and replacement costs. PPH Single Bag Filter Housings have better material and structure, making the whole system more stable and more cost-effective over time. As industry demands higher performance from filtration systems, traditional PP and UPVC can no longer handle high temperatures and strong corrosion for long. With better overall performance and professional designs, PPH filters are now the top choice for chemical, water treatment, electroplating, petrochemical, and other demanding industries.

Core Advantages of PPH Filter Housings

1. High-quality craftsmanship: One-piece injection molding, no joints or welding points, firm structure and leak-proof.

2. Easy maintenance and cleaning: Simple structure, smooth inner wall, quick-open cover or lifting ring, low maintenance cost.

3. Wide industrial application: Industrial-grade, suitable for many industries, supports single / parallel use and customization, stable and reliable.

4. High filtration efficiency: Large flow rate, strong dirt-holding capacity, no bypass leakage, suitable for standard / precision / high-flow filtration.

5. High temperature, pressure and corrosion resistance: Temperature resistant up to 90°C, pressure rated at 8/10 bar, highly resistant to strong acids and alkalis, better than stainless steel, UPVC and standard PP.
