Hello,

I am building a project using a material thats fairly new to me, Styrene.
I have made a large cone from 3mm styrene board, which is about 40cm in diameter.
My issue is joining the seams solidly.

I have bought EMA Plastic Weld from Amazon, [EMA Plastic Weld Glue Cement Glue For Hard To Stick Plastics Weald].
I have also tried Super Glue and a few other obvious ones, none of which seem to have bonding strength I need to fix the joint.

I was wondering if there is anyone out there who might be able to point me to something I can use that might work?
I am in the U.K. so, I am sometimes limited in the brands that I can find in shops or online.

thanks in advance for anyone able to help.

What you're calling Styrene Board in the UK, seems to me to be what we call Polystyrene foam in the US (otherwise incorrectly known as "Styrofoam" in beverage cups and fast food containers). If on the other hand if I'm wrong on the nomenclature, and the Styrene material is more solid (example, thin-transparent, white and black sheets used for modeling at Hobby Shops) then the material in any case still belongs to the Polystyrene family of plastics, which is the same plastic (believe it or not) as CD/DVD jewel cases, disposable razors, and plastic model kits. The "Styrofoam" proper is another brand of extruded dense plastic foam (usually blue in colour) that is used for architectural insulation and is propietary to Dow Chemicals - not the same as the white expanded Polystyrene foam material used for plastic cups. They are all Polysterene, however.



If the crystal form of the plastic is soluble with plastic model cement, then it stands to reason that plastic model glue (eg Testors) might work the same on the foam. However, the biggst problem you have is not the strength of the bond but the weakness of the material itself. It may simply break along the bonded joint...

I have used a spray-on tacky glue that will stick foam and styrene down here in Australia. Look in the craft/glue section of your local craft shop and read the labels. The tacky stuff sticks foam and makes a soft join. Once dry you can't pull it apart. It works the same on styrene.

Right, Super Glue seems to have worked on the Styrene....

My plan now, is to seal the edges with the EMA Plastic Weld, to hopefully strengthen the bond...

Thanks a lot for the responses

I have found EMA Plastic Weld to be fairly average, the plastic glue from Games Workshop is better, same stuff in theory but seems to work better.
Sanding then a thin layer of Araldite (or equivalent epoxy) is also an option. DON'T use contact adhesive it melts and deforms a lot of plastics.
