I have used these glue sticks in a Surebonder PRO8000A (a beastly 180-watt glue gun) to bond sheets of corrugated polypropylene (Coroplast) to EVA foam and polypropylene to itself. The adhesion between the glue and the polypropylene sheets is so strong that the plastic stretches before the glue detaches. Likewise, the EVA foam tears before the glue fails. I have also used this glue on wood, glass, and metal, and it outperforms the typical all-purpose glue sticks in every case.This glue needs to reach very high temperatures (380 degrees F) for proper tack, so you will need an appropriate glue gun. Also, if your work has a large thermal mass, you may need to preheat it with a heat gun so it doesn't cool the glue down toon much before it has time to set.Furthermore, for some plastics, you may need to use sandpaper or heat and solvent to prepare the surface for bonding.As others have noted, this glue is just rebranded tecbond 260, so if you can find that product cheaper elsewhere (like ebay), go for it.When applied properly, this glue bonds low-surface-energy plastics better than most plastic-weld epoxies, and it's so much easier and quicker - so it's highly recommended in my book.
