How to Select a High-Quality CTP (PVI) Supplier?
The quality of anti-scorching agents on the market varies significantly. Inferior products not only offer poor scorch prevention but may also cause blooming or incomplete vulcanization. When procuring, be sure to focus on the following indicators, which represent the core strengths of our products:
| Key Specifications | Our Advantages | Customer Benefits |
| Purity | ≥ 98% (High Purity) | Higher efficiency requires lower dosage, resulting in significant cost savings. |
| Melting Point | ≥ 89°C | High purity ensures excellent dispersion, preventing localized scorching spots. |
| Ash Content | ≤ 0.1% | Extremely low impurity levels guarantee product consistency and electrical insulation properties. |
| Appearance | White Powder / Granules | Easy handling and dispersion; granular forms ensure a dust-free environment. |
Expert Tip: Lower prices aren’t necessarily better. Low-purity CTP often contains unreacted impurities, which not only require increased usage but may also compromise the physical and mechanical properties of rubber.
Frequently Asked Questions (FAQ)
Q: Does CTP affect the final vulcanization speed? A: When used at appropriate levels, CTP merely extends the scorch time (the waiting period before initiation). Once the active vulcanization phase begins, it has virtually no impact on vulcanization speed or crosslinking degree.
Q: Is CTP suitable for EPDM rubber? A: Yes, CTP is suitable for most sulfur-vulcanized diene rubbers, including NR (natural rubber), SBR, BR, NBR, and EPDM.
Q: Can you supply oil-filled or pelletized PVI? A: Yes. To reduce workshop dust and improve dispersion, we offer pre-dispersed masterbatch pellets or oil-filled products, meeting environmental and automated weighing requirements.
