Hdpe glue sticks. Hdpe glue pro poly is a high strength polyethylene adhesive for coupling of hdpe pipe using standard pvc couplings hdpe couplings and other non standard materials. Apply the glue thickly to the surface of the hdpe. Clamp the two pieces together until the glue has cured. When i last researched this 3m was the best option.
One of my viewers commented about using a hot glue gun to extrude plastic. You can buy the glue gun from any source as long as it takes 1112mm glue sticks and gets up to 194 c but youd better buy the glue from a specialty source. With plasma or use an adhesive that is designed for it. Tecbond polyolefin based glue sticks are unique hot melt adhesives with high molten tack good instant grab ability and provided excellent heat resistance and good low temperature resistance.
Light a propane torch and adjust the flame until it is yellow at the tip. However recent innovations have created epoxy based glues that allow hdpe to be attached to other polymers such as pvc fiberglass and steel. Previously hdpe could only be welded together by melting the surface of the hdpe. Supertac 500 plastic bonding hot melt sticks by infinity bond plastic is one of the hardest surfaces to bond to but we have found a hot melt glue stick that will bond polyethylene pvc and pet.
Gluing polyethylene can be difficult however polyethylene can be bonded. The time required will vary by manufacturer. Press the glued hdpe to the surface with which you wish to combine it. Finally with the bonding poly process patent pending bonding any polymer is.
Pro poly is also used for bonding polypropylene ldpe abs polycarbonate nylon fiberglass steel and aluminum. Btw ive been using an app called upside that gives you money. It has an open time of 28 seconds and a set time of 17 seconds. A high temperature glue gun can glue almost all plastics but not with hobby store glue.

No bond polyethylene with the bonding poly process patent pending conventional wisdom is that you cang glue polyethylene. You can either treat the surface eg. The glue comes in a kit containing a tube of glue and a tiny bottle of surface activator.
Yellow flame is cooler than blue flame. I just saw this a couple of days ago at the local home depot. Hdpe is a low surface energy plastic which makes it hard to bond.
