Features and Applications
This hot melt adhesive is ideal for use in co-extruded dual-wall heat shrinkable tubing, offering a range of benefits:
Strong Adhesion: Excellent bonding strength to metals and heat shrinkable materials.
Superior Sealing and Insulation: Provides excellent insulation and ensures a strong seal to protect against moisture and environmental factors.
Environmental Compliance: Non-toxic, with certifications from RoHS and REACH environmental protection tests.
Aging Resistance: Maintains performance over time, even under harsh conditions.
High Productivity: Efficient processing in co-extrusion applications.
Temperature Resistance: Performs well in both high and low-temperature environments.
Professional Sizing Requirement: Must be applied using professional co-extrusion equipment.
Usage and Application
The hot melt adhesive is co-extruded with heat shrinkable material to create dual-walled tubing. The tubing is then cross-linked by radiation and expanded at high temperatures, resulting in dual-walled tubing with heat shrinkable properties. This adhesive plays a critical role in bonding, insulating, sealing, waterproofing, and moisture-proofing, providing multiple layers of protection for the internal components.
Safety Precautions
While solid, the hot melt adhesive is safe and poses no health risks. Once melted, however, it becomes a hot, molten plastic that can cause severe burns. Appropriate safety measures, including insulated gloves and safety goggles, should be used during handling.
Packaging and Storage
The product is packaged in 25kg Kraft paper bags with a waterproof liner. It should be stored in cool, dry conditions. Mixing with other products is not recommended.
