Oxidized Fischer-Tropsch Wax (Oxidized F-T Wax)
Oxidized Fischer-Tropsch (F-T) wax is F-T wax further modified by oxidation, introducing polar functional groups. It combines lubrication with polar compatibility and is especially suitable for the internal/external lubrication balance of rigid PVC. Heyee Chem flagship grades include HY-9128, HY-100-28, HY-104-28, HY-105-32, HY-B39 and HY-B52.
Grades & Specifications
| Grade | Key Specs | Main Use |
|---|---|---|
| HY-9128 | Balanced overall lubrication | PVC profiles, pipes |
| HY-100-28 / HY-104-28 | Mid-high acid value, strong internal lube | PVC sheets, plates |
| HY-105-32 | High acid value | Highly-filled PVC |
| HY-B39 / HY-B52 | High-melting oxidized wax | High-temp processing, engineering plastics |
Typical Applications
- PVC pipes
- PVC profiles/windows & doors
- PVC sheets/plates
- Highly-filled masterbatch
- Engineering plastic lubrication
Frequently Asked Questions (FAQ)
What is the role of oxidized F-T wax in PVC?
It provides a balanced internal/external lubrication, lowers plasticizing torque, prevents mold sticking and improves surface gloss and dimensional stability; its thermal stability is better than ordinary paraffin wax.
What does the acid value indicate?
A higher acid value means stronger polarity and a more pronounced internal-lubrication tendency; high-fill systems often use high-acid grades (e.g. HY-105-32).
What is the difference between oxidized wax and oxidized PE wax?
The former is based on F-T wax, the latter on PE wax; oxidized F-T wax typically offers better hardness and thermal stability and suits rigid PVC.
