Seeing is believing … but it takes awhile.
Since the 60’s, the world has been told that nothing sticks to slick pastics, i.e,, polymers.
Experience has taught us that even when you show people that you can bond, not glue, but bond, PTFE, that you can bond silicone rubber, that you can bond nylon, that you can bond HDPE, it still takes awhile for each individual to accept the truth. We understand. The developer of the Polymer Bonding Process (Proces) spent eighteen months bonding different polymers, every polymer that he could lay hand on, before he accepted that you could actually bond polymers, to themselves, to other polymers and to almost any substrate. Testing has been continuous. With every result, whether locally or internationally, his belief in the Process has grown. Now, our position if that a polymer-to-polymer bond is the strongest join that you can find.
Bonding PTFE (Teflon): to itself, to other polymers, to other substrates.
You have to be of a certain age to remember the phrase “Nothing sticks to Teflon”. During the 80’s, the Reagan ers, it was oft repeated. As you will see in the video, the Process will bond virtually anything to Teflon. Later in the video, you will see that a bond was truly created. There are a number of companies that are bonding Teflon, many of them to steel. In some applications, there are issues to be worked out. We will work those out with IIT, ISM.
We took the above piece to trade shows and challenged people to break something off. Very large individuals tries to twist off the wingnut, to pull off the rubber, to break off the Teflon piece or ot break off the piece of wood. After a year or more, the wood piece split. You will see that in the video. These restults were typical.
More people search for how to glue silicone rubber than how to glue any other polymer.
What is critical to understand is that when you bond siicone rubber, unline when you glue it, the silicone rubber is flexible and even elongates. In other words, silicone rubber is silicone rubber. When glued, silicone rubber is NOT silicone rubber. It’s a hard, inflexible piece of material – not rubber.
When you bond silicone rubber with proper surface preparaton and apply stress, you will always get substrate failure.
In today’s manufacturing world, the steps in the Polymer Bonding Process are not hard to execute.
