Tall oil pitch (CAS 8016-81-7) is a low-cost, versatile industrial material, but buying it well means understanding the grade, the softening point, the COA and the logistics — because it is a solid/viscous material that is harder to handle than a simple liquid or powder. This purchasing guide covers the specification sheet, packaging, storage and the supplier checklist for tall oil pitch.
1. Reading the Specification
| Parameter | Typical value | Why it matters |
|---|---|---|
| Appearance | Dark brown to black solid/viscous | Visual QC |
| Softening point | Grade-dependent (typically 60-120 °C) | Sets handling and application temperature |
| Ash content | Low | Impurity; matters for fuel and adhesive use |
| Acid value | Low (residual) | Reactivity and storage |
| Moisture | Low | Consistency |
2. What a Complete COA Should Contain
- Product name and CAS number (8016-81-7)
- Batch number and production date
- Softening point (measured)
- Ash content (measured)
- Acid value and moisture
- Appearance
- Test methods and quality manager signature
3. Packaging, Storage and Handling
- Packaging: typically solidified blocks, pellets, flakes or drums; some grades in hot-melt tanker.
- Storage: cool, dry; keep away from ignition sources. The material is flammable at elevated temperatures.
- Handling: it is solid at room temperature — requires heating (melting) for pumping; follow the SDS.
- Shelf life: generally stable for 12-24 months when stored properly.
4. MOQ, Lead Time and Logistics
- MOQ: from pallets/drums to container loads; hot-melt tanker for large industrial users.
- Documents: invoice, packing list, COA, MSDS, certificate of origin.
- Shipping: confirm the transport classification and any heat/melt requirements with your forwarder.
5. How to Verify Quality on Arrival
- Check packaging and labels against the COA batch number.
- Visual check: consistent dark color, no foreign matter.
- Verify softening point with a simple test against the COA.
- Run a small application trial (adhesive, fuel, waterproofing) against your current batch.
- Keep a retained sample per batch.
6. Supplier Checklist
- Manufacturer vs trader — manufacturers control grade consistency.
- Consistent COA with measured softening point and ash on every batch.
- Packaging suited to your handling (blocks vs pellets vs tanker).
- Stable supply and reasonable lead time.
- Price comparison on a per-kg basis at the same grade.
7. FAQ
What is the difference between tall oil pitch grades?
Grades differ mainly by softening point, ash and acid value; the right grade depends on your application (adhesive, fuel, waterproofing).
Is tall oil pitch hard to handle?
It is solid at room temperature and must be melted for pumping — choose packaging (blocks vs pellets vs tanker) that matches your handling.
Is tall oil pitch flammable?
It is combustible, especially when heated; follow the SDS and keep away from ignition sources.
Can I get a trial sample?
Yes. PolyblueChem offers trial samples so you can validate the product before bulk orders.
