I'm not sure if this is the correct forum to ask this question in, but does anyone know where I can order some Trimethylolethane or Lauric Acid from? I'm looking to get these two phase change materials for a project we're working on at work and haven't had much luck!
Thanks so much for any...
I had another thread started on the topic of cooling water, but I figured I'd start a different one since I'm exploring a whole new avenue.
I'm trying to cool 8 ounces of 70 deg C water down to 38 deg C. I want to do this all in 2 minutes, but with as low a cost as possible. I was thinking of...
OK, so I've been working on a few different things lately and one that I've been fumbling around with is being able to heat up water to about 70 deg C, then back down to about 38 deg C...all in less than 2 minutes too lol.
I can't really think of a way to get the water down to almost half the...
I'm trying to find the stress/strain relationship of a Cylindrical component (Nylon) when it has a carbon based Stainless Steel to help with conductivity. The SS piece is stationary during use as is the Nylon piece. The entire assembly has an SS cylinder around it which has a .002"...

I'm trying to bond two Polypropylene components together. I know PP is tough to adhere anything to and I haven't had much luck with some of the Locktite grades that I've tried. Does anyone have any suggestions for how I can adhere these two PP components together?
Hey guys,
I'm looking for a method that will help to agitate a cold liquid and while simulaneously introducing CO2 into the liquid. The bottom of the container that will have the liquid in it will be sealed and the only access into the container will be through the neck of the bottle on the...
I'm designing a cylinder-shaped sealing component to a part that needs to have a face seal on the distal end of the part and a seal on the OD as well. I've attached a sketch of what I'm thinking for the component.
The part will need to be a single durometer material (to be chosen after the...
I was asked a material question today and I remember that you guys are the materials experts! The part will be rubbing on another plastic part made of PEEK, so we’d like the material to be soft compared to PEEK where the PEEK will wear the material it’s rubbing against. We’re looking to have a...
We have an ABS part that undergoes accelerated age testing. The test is being ran at 56 degrees C for four months. We're finding that about 10% of the parts are snapping after the test is done. The part is a lever within a handle that is used to actuate certain pieces within the handle when...
I have a medical component that goes into a laparoscopic instrument. We have the component coated with a DLC (Diamond-Like Carbon) coating. We're having an issue with the surface finish of the part after coating. The coating we're using seems to be a little rougher than we'd like, so we're...
We had some of our 17-4 PH Stainless Steel recently coated with TC40 and TC 41 films. The coating was fine when we received it, but it started to flake as we started passing another metal along it (it's used as a clamping jaw in a feeder system with metal clips). The 17-4 was solution annealed...
We're working with a piece of 17-4 PH stainless steel which is annealed. We had applied one coat of metal containing hydrogenated amorphous carbon film to the steel. The vendor then, without consenting us, coated the steel again; but this time with a hydrogenated amorphous carbon film...
Hi guys,
This is my first post, so hopefully I'm clear enough in my question...
