News
  • How do you distinguish between primary and secondary raw materials?

    Primary vs. Secondary Raw Materials The fundamental distinction lies in the origin and processing history. Primary raw materials are extracted directly from natural resources (ores, crude oil, forests) and have never been used or processed industrially before. Secondary raw materials are recovered from pre-consumer or...

PPN Pipes Industry knowledge

What are the main materials of PPN pipes?

1. Modified Polypropylene (PP): PPN pipes use polypropylene (PP) as the matrix, which is β-modified or copolymerized to give it higher temperature resistance, chemical corrosion resistance, and aging resistance.

2. High Transparency and Low Water Absorption: PPN material has an extremely low water absorption rate (≈0.01%), and hardly expands in aquatic environments, making it suitable for industries highly sensitive to moisture, such as cleanrooms, pharmaceuticals, and semiconductors.

3. Excellent Mechanical Strength: The modified PPN pipe wall is dense, significantly improving impact strength and pressure resistance, and can operate stably in a wide temperature range of -10℃ to +100℃.

What are the differences between PPN pipes and ordinary PP pipes (PPH)?

1. Compositional Differences: PPN pipes use polypropylene raw materials directly, while PPH pipes are β-modified from ordinary PP to form a more uniform and delicate β-crystalline structure.

2. Performance Comparison:

Chemical Resistance: PPN performs better in strong acid and alkali environments, exhibiting stronger corrosion resistance; while PPH also possesses good chemical resistance, it is slightly inferior.

High Temperature Resistance: PPN can be used continuously at temperatures above 100℃, suitable for high-temperature process pipelines; the maximum operating temperature of PPH is generally around 90℃.

Abrasion and Aging Resistance: PPN pipes exhibit superior abrasion resistance and anti-aging properties, resulting in a longer service life, making them particularly suitable for harsh conditions such as chemical and pharmaceutical industries.

3. Application Scenarios: PPN is more inclined towards high-end photovoltaic, semiconductor, chemical, and pharmaceutical fields where extremely high material purity and temperature resistance are required; PPH is commonly used in general industrial pipelines, water supply and drainage, and medium- and low-pressure transmission systems.
