Why are the furniture boards produced using PUR hot glue? (Advantages of PUR Technology）
Compared with traditional glue (such as epoxy resin) or thermoplastic film (such as EVA and PUR hot glue) PUR laminating machine production line.
PUR honeycomb production lines have irreplaceable advantages:
Extremely high bonding strength: especially “peel strength”, which is the core indicator for measuring the
quality of honeycomb panels. After curing, PUR adhesive forms an irreversible cross-linked structure, with
a strength far exceeding that of thermoplastic films such as EVA.Excellent weather resistance: Resistant to high and low temperatures (stable performance from -40℃ to +80℃), damp heat, aging and solvents. This makes it highly suitable for use on the exterior walls of buildings and in vehicles with variable environments.
Environmentally friendly and solvent-free: PUR adhesive is a 100% solid content hot melt adhesive. There is no VOC (volatile organic compounds) emission during the production process, which complies with the strictest environmental protection regulations (such as the EU’s REACH regulation), and is friendly to workers’ health and the factory environment.
High production efficiency: The production line integrates gluing, lamination, hot pressing and curing, with a high degree of automation and a fast production cycle.
The flatness of the sheet is excellent: The continuous flat pressing process under high temperature and high pressure can produce sheets of extremely large size and very flat, with almost no wavy deformation.
Feature / Metric
1.PUR Honeycomb Production Line Panels
2.Traditional Process (e.g., Epoxy Resin) Panels
Bonding Strength
1.Extremely High, especially peel strength
2.High, but peel strength is generally lower than PUR
Weather Resistance
1.Excellent, resistant to high/low temperatures, heat, and humidity
2.Average, prone to aging in high-temperature or humid environments
Environmental Friendliness
1.Excellent, solvent-free, zero VOC
2.Poor, contains solvents, has VOC emissions
Production Efficiency
1.High, continuous and automated production
2.Relatively Low, requires longer curing time
Panel Flatness
1.Excellent, continuous flat-pressing, dimensionally stable
2.Average, susceptible to pressure and curing stress
Cost
1.High production line investment, but advantageous overall cost Material cost may be lower, but overall cost is higher
2.When you need to produce high-performance, high-value-added honeycomb composite panels for harsh
3.environments, the PUR honeycomb production line is the most advanced and reliable choice today.
It is almost the “standard” production process for high-end architectural curtain wall panels, rail transit interior panels and high-end furniture panels.
