Thread: Polypropalene Glue

Try heating the two edges to melting point and then pushing them together, that is how they weld the big black plastic pipes together for industrial applications and I think they are polypropalene.

there is no glue that will stick it together, even silicon doesn't hold

Labels on bottles made of these materials are usually sprayed-on hot-melt. Needs a large contact area and intimate contact. No good for actual structural fixings. Depending upon loading conditions, welding may not work very well either owing to prying forces on a small contact area. Might be best to use mechanical connections e.g. nuts and bolts (galvanised or stainless), and seal by welding or polyurethane caulk.

Hi,
We have had some success with repairs on polyethalene water tanks with this product.
Its an MS polymer, a cross between a silicon and polyurethane.
Extrememly strong, elastic product.

It might be worth a trial as not much will bond those materials.

Hot air welding is the only way, its what they use for modern car bumpers to fix them as they are made from this super plastic.
There are some on Ebay

Thanks all

Ill see what I can get now

I need to cut shape and join some storm water channel which I am told is polypropalene
If it also joins Polyethalene that would be a bonus

If someone knows of channel and drain made in PVC that would be usefull as well as I am told it no longer is made and PVC is being phased out

Thanks for your help

Doug

This is the only glue that will fix polyprop. I have used it with great success in the past.

CRL Loctite Plastix™ Advanced Plastic Bonder with Surface Activator

Thanks and many regards

Hi,
I think you will find the Loctite plastix is a cyanoacylate (super glue) with an extra activator.
Yes it will work on those materials, but it will not have the gap filling capacity required for this job. I would imagine its not exactly precision joins being bonded.

Just my 2cents..

cheers

Here is a picture

Learner's link (dkhardware) is a distributor in Miami FL USA, apparently selling case lots. Yesterday, I telephoned Loctite with a separate enquiry and by the by asked about this product (#82565). Very nice lady advised me that they sell quite a bit of it through our Home Depot, Lowes, Ace Hardware and such. So it's likely available at Bunnings too.

Regarding gap filling, I had an earlier experiment which failed to adhere sufficiently with polyurethane sealant alone. The possible solution, not disputed by the nice lady, might be to apply Plastix to each surface and then use the polyurethane sealant for gap filling. Not sure if it would utilise activator only, but it definitely seems worth a series of experiments (two ways each surface, total of four I think). Placed on my to-do list.

The separate enquiry was concerned with date codes and shelf life of recent purchases, and follow-up on my earlier suggestions for human-readable codes before purchase. My suggestions suffered from Not-Invented-Here syndrome, and their more complicated implementation is still a work in progress.

Doug,
if it's storm water drains you need to cut and join can't you cut them to size, set them in place in the ground with a bit of space in the hole around them and pour concrete in around the pieces to hold it all in place?

The loctite product is NOT AVAILABLE IN AUSTRALIA or at Bunnings.

However we have made copy with similar activator.
