If the fibre tear of A is strong enough, why use B ?

How much extra adhesive is used by bead B ? A B About Ellsworth | Ask The Glue Doctor | Engineering Sales Reps | www.ellsworth.com

If we start with the original glue bead… … and then half the bead width, how much do we save ?

½ the original bead Reality is close to 4X About Ellsworth | Ask The Glue Doctor | Engineering Sales Reps | www.ellsworth.com

Why is it common to use too much adhesive ?

Often because we have blocked nozzles from system CHAR.

So … 1 We increase the size of nozzles = About Ellsworth | Ask The Glue Doctor | Engineering Sales Reps | www.ellsworth.com

Or ...

2 Because we increase the pump pressure Pump visual of the glue bead pressure with same nozzle size 1.5 bar = 2.0 bar = 2.5 bar = 3.0 bar = 3.5 bar = = 0.45 g/m = 1.0 g/m = 1.4 g/m = 2.4 g/m = 3.2 g/m % increase in adhesive consumption = 122 % = 211 % = 433 % = 611 % NOTE: 1 Bar = 14.5psi

Hot Melt Technology Platform Value / Performance Grid… “You have choices”… Polyethylene Hybrid PE Low Temp.

EVA Hybrid EVA EVA Metallocene Performance

As we move up the value / performance grid, what benefits do we achieve?...

1 Adhesives that are more viscosity stable and resist charring. Both avoid having to increase nozzle size and change system pressure.

As we move up the value / performance grid, what benefits do we achieve?...

2 Adhesives that cut off cleanly rather than produce a “tailing” effect. Clean cut-off means less clean up, less downtime and less adhesive consumed.

As an adhesive user, you have the ability to…

• • • •

Achieve lowest total cost of ownership

Minimize internal and external costs. 10-40% savings are typical and achievable.

Increase Mileage

10-35% mileage advantage is attained through lower density, thermal stability, precise application and aggressive bonding.

Reduce Line and Maintenance Costs

Eliminate char. Less nozzle, module & hose replacements. Reduces line, tank and cleaning costs.

Increase Plant Yield and Throughput

Reduced downtime and rejects. Fast speed of set yields maximum line speeds.
