Sticking Plastic To Stuff

13 Jul

I often get inquiries about attaching plastic to wood, metal, glass, or other stuff – in the biz the stuff is called a substrate.

IPS is a company specializing in sticky stuff for plastic and I suggest you start there to figure out exactly what you need and then give us a call or visit one of our stores to place your order. We stock primarily acrylic, vinyl (PVC), and styrene cements as well as a few other two-parters so you may want to call first to see what’s available.

NOT ALL PLASTICS STICK REAL GOOD. The fact is, some plastics were designed not to. These fall into families such as mechanical and industrial plastics such as acetal, polypropylenes, polyethylenes, and PVC’s. These products are used in applications where you don’t chemicals affecting their containment systems. For example, polypro or HDPE are commonly used to contain nasty chemical baths for electroplating metals. These materials are welded together similar to how metal is welded.

Polypropylene Chemical Baths

On the other end of the spectrum are the acrylics, polycarbonates, PETG, and styrenes which are your primary fabrication materials – why? because you can stick them together or stick other things to them.

PVC, however, is the magic plastic because it is both resilient to a lot of chemicals AND you can cement it together making it very easy to work with to fabricate into fume hoods and ducts…

However, for larger PVC applications, such as creating chemcial baths, it’s also common to weld it…

(notice the curly, thin-gauge rod being used to weld the pieces together)
