16# Granular C9 Petroleum Resin

No. 16 granular carbon nine petroleum resin is a thermoplastic resin made by polymerization reaction with C9 fraction in the process of petroleum cracking as the main raw material. The following is a detailed introduction of the product:

1. Basic characteristics

- Appearance: Usually light yellow to amber solid particles (No. 16 particles may refer to a specific particle size range, such as about 1.6mm).

- Softening point: Depending on the process, it is generally between 80-150℃ (common models are 100-120℃).

- Molecular weight: medium (about 1000-3000), with good solubility and compatibility.

- Stability: Acid and alkali resistant, but long-term high temperature exposure should be avoided to prevent oxidation.

2. Main application areas

- Adhesive industry: As a tackifying resin, it is used in pressure-sensitive adhesives, hot melt adhesives, etc. to improve initial adhesion and lasting adhesion.

- Coatings: Enhance the adhesion, gloss and drying properties of paints and inks.

- Rubber processing: as a softener or reinforcing agent, it improves the processability and wear resistance of rubber products.

- Others: can be used for asphalt modification, waterproof materials, etc.

3. The meaning of No. 16 particles

May refer to:

- Particle size: such as 16 mesh (about 1.18mm) or a model marked by a specific manufacturer.

- Softening point grade: Some manufacturers use 16 to indicate a softening point of about 100-110℃.

- Customized model: It is recommended to consult the supplier for specific technical parameters.

4. Storage and transportation

- It needs to be sealed and stored in a cool and dry place to avoid moisture absorption or high temperature agglomeration.

- Pay attention to fire and moisture prevention during transportation, and treat it as a non-hazardous chemical (the specific details are subject to the test report).

5. Purchase suggestions

- Test indicators: focus on whether the softening point, color (Gardner), acid value, etc. meet the requirements.

- Compatibility test: test the mixing effect with the base material (such as SBS, EVA, etc.). - Environmental protection: If export or high-end application is required, confirm whether it meets RoHS/REACH and other standards.
