Why use weather resistant hot melt adhesive particles for exporting books and periodicals? Compare with ordinary rubber particles to see the difference

Conclusion first: Exported books and periodicals need to be transported across the ocean, through high-temperature containers and temperature differences between high and low temperatures. Ordinary rubber particles are prone to sticking or becoming brittle during transportation, while weather resistant hot melt rubber particles have a higher softening point and a more balanced resistance to high and low temperatures, which is the key to ensuring the quality upon arrival. For export orders, spending more money on rubber granules can save a lot of money on returns and claims.

Three major tests in the export process

• High temperature containerThe temperature inside sea freight containers can reach over 60 ℃ in summer, and if the softening point of ordinary rubber particles is not enough, they will stick back and the pages of the book will adhere;
• High and low temperature cycleTransportation across climatic zones, repeated exposure to cold and heat causes brittle adhesive layers to crack and peel off;
• Long term compressionStacking and stacking for several weeks, the adhesive layer needs to maintain cohesion and prevent creep.

Comparison between weather resistant and ordinary types

What order is worth upgrading to weather resistant

For books and periodicals that are sent to high-temperature areas such as the Middle East and Southeast Asia, or require long-distance sea transportation and storage for several months, it is recommended to directly load them with weather resistant materials; Regular books and periodicals stored at short distance and room temperature in China can be stored in regular book and periodical granules without blindly upgrading. Guangzhou Sunlife Trading can help export customers match models according to the destination climate and transportation cycle, and provide high and low temperature testing references.

Frequently Asked Questions

Q: How to determine if there will be a return of adhesion after arriving at the shore?
Can be used for high-temperature storage simulation testing (such as checking adhesion after 48 hours at 60 ℃), Sunlife hot melt adhesive can provide relevant test data reference for weather resistant models.

Q: How much is the weather resistant type expensive and is it worth it?
The unit cost is slightly higher, but in the event of adhesion or detachment during sea transportation, the losses from full container returns and claims far exceed the price difference of the rubber granules, and export orders should be included in this total account.

One sentence: When selecting adhesive for exporting books and periodicals, it is important to consider the destination climate and transportation time. If weather resistant type is required, do not skip this step.
