Selecting the right PP (Polypropylene) fibrillated yarn requires focusing on tensile strength and fibrillation consistency. For industrial use like rope making or cable filling, ensure the yarn has a high tenacity rating (typically >5g/denier) to prevent breakage under tension. Check the denier range (usually 10,000D to 100,000D) to match your specific machinery requirements. Additionally, verify the UV stabilization level, especially if the end product will be exposed to sunlight, to prevent polymer degradation.
