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.
Bidding for hot melt adhesive granules, if the technical specifications are not clearly written, the goods will look the same and be overturned when they arrive. Below is thisList of 8 terms and conditionsCovering two commonly used adhesives for book binding and packaging, they can be directly copied into the procurement documents. 1、 List of […]
Direct conclusion: EVA hot melt adhesive particles have fast curing, high initial adhesion, and affordable price, making them the main force for book binding and carton sealing; APAO hot melt adhesive particles have a long opening time, wide temperature resistance range, and good flexibility, making them more suitable for large-area composite and weather resistant applications. […]
One sentence distinction:Initial adhesion refers to whether one can grasp it at the moment of attachment, while holding adhesion refers to whether it can be firmly held for several months.The adhesive packaging of books and magazines places more emphasis on adhesion, while high-speed sealing places more emphasis on initial adhesion. The two often have a […]
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 […]
