Gluing High impact polystyrene

[Gins]

Hi:

Am looking for a solvent or adhsive to glue two injection molded HIPS together with a solid joint.

Would appreciate some suggesitons.

Thanks

Hello,

High impact polystyrene, as you probably know, is polystyrene with about 8-10% butadiene rubber particles in it to give the added impact resistance. That means the continuous phase is polystyrene and so you need a solvent for PS. Solvents that I am nearly positive will work include toluene, acetone, THF and MEK. There are others too if you need more alternatives. Such solvent welding should work although the welded joint is likely to have somewhat lower strength than the rest of the part.

Hi Gins,

Cyanoacrylate adhesives work well on HIPS (and ABS).

You may find the joint will be stronger than the parts!

I would not recommend solvent joining due to health and safety issues (although read the caveats for cyanoacrylates!)

Solvent bond using ethylene dichloride. Properly done, strength will be 100%. Ventilation is needed.

I've used finger nail polish remover (acetone) to solvent bond model cars and planes (polystyrene) with good success.

Good luck,
