Hello , now , you use a term I,ve seen , heard and pretty much ignored . The old sales saw " high impact styrene " was to alleviate folks fears that the plastic glass they were using wouldn't collapse when they set it on the table hard.
All in all , styrene is pretty much "HIGH IMPACT " it,s molecular structure is much more compact and tighter bonds exist at that level.Most styrene glues will work , and surprise , on some , even lacquer thinner will work . tankerbuilder
