Default Re: Glue for plastic

I've had good luck bonding polypropylene with 'glue gun' hot glue. It works well for the children's garden toys which have a fairly hard life.

For really difficult plastic repairs, I've used a cement called Scotch-Weld 8005 before. It sticks PEVA (also used in a lot of baby-related things) and other waxy plastics quite well. My biggest triumph was re-sticking the sole of a cross-country ski boot back on. It was made of something really slippery, maybe polypropylene, and had come clean off the bottom of the boot. The bond has to withstand the entire stress of someone skiing, and it worked. The down side is that the adhesive cost almost as much as a new boot would have done, but I'd borrowed it from a friend so wanted to make good!
