Platen Options for 55 Gallon PUR Hot Melt Drum Unloader

Let's start off with what a platen is. A platen for a 55 gallon drum unloader is the mechanism that presses down on the drum and melts the adhesive for dispensing. There are two types of platens available for the this drum unloader that will affect melt speed and ease-of-cleaning. 

Flat Platen for Drum PUR Melter

A flat platen is, well, flat. It makes cleaning the machine after using much easier but provides a lower melt rate of 130 LBS (60 KG) per hour. Great for low to mid volume applications that are looking to cut down on cleaning time. 

Fin Platen for PUR Melter

A fin platen offers a ribbed surface and a much higher melt rate of 285 LBS per hour (130 KG) which is great for higher volume applications. But, those ridges are harder to clean making maintenance a little more time consuming.

 Understanding PUR Hot Melt vs Traditional Hot Melt

What's the same? 

Both traditional hot melt and polyurethane (PUR) hot melt typically needs to be heated to be applied. They are both non-toxic and generally one of the safer adhesives for bonding and sealing

  • Non-toxic
  • Applied by heating and dispensing

What's different?

PUR is a so-called "reactive" adhesive because a chemical reaction needs to take place for the strong adhesive bond to work. Some moisture needs to be present to spark that chemical reaction and create the adhesive bond. The good news is that sufficient moisture exists in the air around us and usually in the material being glued.
