Previously hdpe could only be welded together by melting the surface of the hdpe.
What will stick to polyethylene.
Bonding polyethylene is considered very difficult and as a result it is often used as packaging for adhesive materials as the glue won t stick to it.
Even un cured caulk barely sticks.
But there is a partial solution to using an adhesive sealant with polyethylene.
The glue works well with polyethylene and polypropylene surfaces.
Because of polyethylene s non stick properties it is commonly used as packaging material for tapes and adhesives.
I bet you could get a coal to stick to a boat.
This group includes teflon or polytetrafluoroethylene.

Polyethylene and polypropylene plastics are used in a number of packaging shipping and production products including plumbing fittings bottles and automotive parts.
If exposed to flame the surface layer undergoes chemical changes that dramatically improve bonding.
This is why the tips of caulking guns are polyethylene.
While the chemistry of polyethylene is stable it will burn.
It is often abbreviated to ldpe low density polyethylene or hdpe high density polyethylene.
It bonds with hard and soft plastic.
These plastics are designed to take a beating and are generally chemically resistant.
Finally with the bonding poly process patent pending bonding any polymer is always quick easy and permanent.
The loctite all plastic super glue includes a tube of bonding agent and a bottle of surface activator.
High density polyethylene hdpe is used for milk cartons fuel tanks and pipes.
I once had a coal stick to my old polyethylene drysuit.
Whenever and wherever we state that we can bond polyethylene polypropylene or any other polymer the universal reaction is skepticism.
Polypropylene and polyethylene are called low energy or non stick plastics.
The basically inert or inactive molecular structure of pp and pe is described as a low energy state.
According to the ridout plastics company such chemically.
However making polyethylene bond to itself or to any other material typically takes industrial scale measures.
Polyethylene is a lightweight thermoplastic.
You can enforce it using an increased surface sanding or oxidizing flame but the best thing to attach something.
