Polyetheylene to Polycarbonate - Adhesive
Polyetheylene to Polycarbonate - Adhesive
(OP)
Hello,
I am working on a project for work and I am finding a real hard to time to find an adhesive that would stick Polyetheylene to Polycarbonate. I know there are some adhesives that are out in the market however they are flammable and therefore cannot be used in our manufacturing environment.
I need your expertise. Please advise.
Thank you for response in advance.
Steve

Sorry for you but POLYETHYLENE, POLYPROPYLENE and PTFE have no adhesive, not at all. The only possibility is mechanical connection

TomQuinn and CompositPro - I will give you more info on what I'm trying to do.
I'm trying to adhere a motion sensor lens to a polycarbonate plastic housing.
There is a small gap all the away around the sensor that needs to be filled. The housing has a "bowl" for the adhesive to sit in. The adhesive will be dispensed with an automated equipment.
The sensor itself is only good for +60°C so any adhesive must have an application temperature lower than that. The adhesive must also be clear when cured. This will eventually be build for production quantities - not sure exactly how many per hour but definitely not thousands/minute.
Thanks for the quick responses.

For your application a soft silicone rtv sealant should work fine.
RE: Polyetheylene to Polycarbonate - Adhesive
I was thinking the same thing. The requirement of being clear with low application temperature limits the options.

I've used this before with reasonably good results on polyethylene tubing; it will stick with no surface prep, albeit with a somewhat low bond strength. It also sticks to polycarbonate well. It's cure time is temperature dependent, and will take a while in thicker applications.
