Polypropylene Multifilament: Industry Standards And Usage Precautions

The quality of polypropylene multifilament must comply with national standards (such as GB/T 17640-2008) or relevant industry standards. Key testing parameters include linear density deviation, breaking strength, and elongation at break. Important considerations for use include:

‌Temperature Limitations‌: Polypropylene has a relatively low melting point (approximately 165°C); prolonged exposure to high temperatures may cause material deformation or performance degradation.

 

‌UV Resistance‌: Long-term outdoor exposure requires the addition of UV stabilizers to prevent aging and embrittlement.
‌Compatibility‌: Contact with certain chemical substances (such as strong oxidizing agents) may trigger reactions; compatibility testing should be conducted beforehand.
