Legitimate hot melt adhesive particles should come with a testing report when leaving the factory. Newcomers are often discouraged by a bunch of indicators, but in fact, by grasping a few key items, one can judge whether it is good or bad. Below is a comparison of the core indicators.
| indicator | What are you looking at? | Good material performance |
|---|---|---|
| softening point | Temperature resistance and seasonal stability | Consistent with the nominal value and with small batch differences |
| Melt viscosity | Flow and Coating | In the recommended range |
| volatile matter | Odor and Bubbles | The lower the better. |
| peel strength | Adhesive strength | Compliant and stable |
| RoHS/VOC | Environmental Safety | Compliance passed |
Q: Can I buy without a report?
Answer: It is not recommended for mass production. Sunlife hot melt adhesive provides testing data along with the goods.
Q: The higher the indicator, the more advanced it is?
Answer: Wrong, matching the production line is the best, blindly setting high targets can easily lead to glue overflow.
Q: How to verify the authenticity of the report?
Answer: To obtain a third-party report number, you can verify it with the institution.
Procurement requires a report, and Sunlife Hot Melt Adhesive from Guangzhou Sunlife Trading provides complete testing data.
Let me start with a true story that I’ve been remembering for eight years. In the winter of 2016, a printing factory owner called me at 11 a.m. and started off by saying, “Brother Shu, something big has happened. The 50,000 textbooks I just bound have their adhesive ridges broken on the first page. The […]
The characteristics of EVA hot melt adhesive: Hot melt adhesive is a solid, fusible polymer that does not require solvents and contains no 100% moisture. It is solid at room temperature and turns into fluid and viscous liquid when heated to a certain temperature. Melted EVA hot melt adhesive is light brown or white. EVA […]
Hot melt adhesive particles for high-speed sealing of cardboard boxes are not necessarily better with higher tensile strength. The sealing fastness also depends on the wetting of the corrugated paper by the adhesive particles, the cooling speed of the adhesive dots, the spraying rhythm, and the pulling direction during transportation. Sunlife hot melt adhesive recommends […]
Hot melt adhesive granulesHow to store after opening? Comparison and evaluation of three storage methods The storage method of hot melt adhesive particles after opening directly determines whether they can still be used and whether they stick firmly. We took the same batch of Sunlife hot melt adhesive particles and stored them in three different […]
