Advantages of Using PUR
Advantages of Using PUR
In work with hot melt adhesives, reactive hot melt adhesives are gaining ever more importance. In the last decade, the outstanding qualities of reactive polyurethane hot melt adhesive, or PUR for short, have especially distinguished themselves, making high strength bonding possible. The unusually high adhesion properties of polyurethane combined with its other characteristics make it possible to bond hitherto “unstickable” products.
You’ll find more in-depth information on reactive hot melt adhesives in our glossary on our homepage.
Advantages for you when using PUR (reactive polyurethane) hot melt adhesives:
- outstanding adhesion to a wide range of materials
- very good low and high temperature performance
- permanent elasticity and flexibility
- for especially high strength / construction bonding
- resistant to many chemicals and solvents
- waterproof
Reactive PUR hot melt adhesives in our range are include 0931.1; 1075.1; 1387; 1528.1, 2241, 2456, 2767.
Adhesives in the Mattress Industry
Adhesives in the Mattress Industry
The hot melt adhesives B 2635 and B 1596 are two specialists in our product range that are particularly suited to the demands of mattress manufacturing. Both hot melts are perfectly adapted to the requirements for use in bonding foam material for mattresses and upholstery. B 2635 is available both as granulate and in pillows and is known for its very reasonable price. B 1596 is designed primarily for large-area bonding and additionally available as blockware or meltpack.
Both polyolefin-based hot melt adhesives are solvent-free and have a comparatively short curing time, making for efficient production with rapid further processing. Our B 1596 even has the eco-passport, which allows it to be used in textile manufacturing in accordance with the OEKO-TEX® Standard 100. What is special about both hot melt adhesive types is that, in their cured state, they are both soft to the touch and are not experienced as a source of irritation within the mattress.
Our Experience in Spray Coating for Your Projects
With many customers and successfully realised projects to our name, we can look back on 35 years of experience in spray coating. As early as 1979 we filed a patent application for this ground-breaking technique of hot metal adhesive coating.
The principle is actually very simple. As the thin adhesive leaves the nozzle, it is diverted sideways by an air vortex, carried along and applied in a circular pattern to the surface of the workpiece.
The technique does not coat the entire surface area with adhesive, but deposits fine lines of adhesive that meet in circles on the surface of the workpiece. Where the fine lines meet each other, they then form points which have a stronger adhesion. The advantage, however, comes primarily from the larger area which can be coated with a comparatively small amount of adhesive. The result is planar, particularly strong adhesion bonding.

Since the hot melt hoses for hand-held guns were successfully converted to the mini version, from 1 October 2014 the hot melt hoses of the KS series for application heads in the mini version are also available.
The TPE corrugated hoses reduce the hose diameter and offer greater flexibility combined with lower weight. These features expand the application area of the heated hoses, especially in automated applications.

Ideal for Frozen Foods: Hot Melt Adhesive avenia B42507
The frozen pizza is favourite snack – and not just when you’re watching the football. But who wants to stick a pizza in the oven when its packaging has come open while it’s still in the freezer? Probably no-one.
Adhesives for frozen food packaging must be absolutely reliable at subzero temperatures. Ideally suitable for this is for example our new avenia B42507. Packaging sealed with it can reliably stand temperatures as low as -20°C.
The avenia B42507, available in granulate form, doesn’t just excel in its flexibility with cold temperatures.
