FAQ:

1. What’s the difference between PP fiber and steel fiber?
PP fiber focuses on micro-crack control and secondary reinforcement; steel fiber is for main structural bearing. They can be used together for better performance.

2. Can PP fiber be used in mortar?
Yes, widely used in dry-mix mortar, plastering mortar to improve anti-crack and anti-seepage.

3. Does PP fiber affect concrete workability?
Proper dosage will not affect workability; our modified surface ensures good dispersion without agglomeration.

4. How long is the service life in concrete?
Inert material, no aging, no corrosion, same service life as concrete structure.
