Use two-part epoxy or neoprene-based cement.
1. Clean both surfaces well, using a cleaner such as alcohol to eliminate even fingerprint oil.
2. Roughen both edges that will be bonded - the side of the plastic and the side of what whatever you are going to adhere to it using 4-0 sandpaper.
3. Oxidize the surface of the plastic with an open flame, such as a hand-held torch, using just a couple of very quick passes. Do not allow the material to blister.
4. Apply adhesive to both surfaces, and allow to dry until it becomes tacky.
5. Press the pieces together and clamp tightly. Allow to sit overnight.
Effective adhesion depends on load, humidity and temperature, so there is no guarantee. These are recommendations only.
