Permabond has developed a line of specialty acrylic adhesives for polyethylene that form strong bonds without surface treatment or primer.
PE is the abbreviation for Polyethylene. Low density polyethylene is LDPE and similarly HDPE for high-density Polyethylene. Lastly, UHMW stands for Ultra High Molecular Weight polyethylene. Although Polyethylene is a thermoplastic material that can be challenging to bond these structural acrylics form excellent bonds.
Permabond TA4605, TA4610, TA4611, and TA4631
TA4605 fixtures in under 10 minutes. Select TA4610 for a longer open time bonding larger surfaces. TA4605 and TA4610 contain microbeads that induce the ideal gap. Select TA4611 for small gaps. TA4631 is a low odor (honest virtually no odor!).
These structural acrylics adhesive for polyethylene have good impact resistance and also good environmental resistance. If you require strong HDPE glue for a rugged application, this is undoubtedly the best option. Download the flyer!
Use primer Permabond POP with cyanoacrylate adhesives to bond polyethylene. Cyanoacrylates set almost instantly and provide good adhesion to HDPE provided the surface is pre-treated with Permabond POP primer. The bonds resist non-polar solvents but do not fair as well with polar solvents.
Providing some form of surface treatment such as flame, corona, or plasma treatment used epoxy and UV grades can be tested. Flexible epoxy such as Permabond ET515 is preferred.
