Hi There,
I am looking for a high stiffness material that can be injection molded. Actually I try to use fibers to bring up the plastic strength several folds to close to that of soft metal, but a small component of this product cannot be reinforced by fibers. This component need to hold the...
Hi there,
I am looking for a fire rated aluminum tube or sheet metal that can pass fire test such as UL2196 or NFPA130 or NFPA502. I am not a metal person and after googling I could not find an answer. Please recommend a aluminum that can do this. Thanks. Or a treatment that can help aluminum...
This coupling is connecting a 100mm pipe to a 150mm pipe. The contract molder was using a 280ton JSW (max rate 32oz/s) to mold the single cavity mold, with the circular gate (2mm at part) at the larger outlet surface. The thickness is about 5mm for both outlets except the joint a little thicker...
Hi, I noticed the plastics are likely to degrade easier/quicker near sea (or in sea water) when it is in contact with metals. I feel there are some electrochemical activities going on. Can anyone help me understand this phenomenon, and is there any literature discussing it?
Thanks!

I am new to coating materials and methods. But our product has recent need to get new coating material and method. So I am trying to get myself educated a little more besides my basic chemistry and polymer knowledge. Our product is zinc galvanized steel part.
There are so many coating...
For the plant, when they process the parts off the process parameters, the plastics got degraded and in my case become brittle for nylon. However many times it looks good until you test the product. Is there a quick way to evaluate the brittleness of a plastic? Thanks. The part is quite small...
Hi There,
I want to model a blocking function realized by two polymer parts, with one part (blocking) made of hard PEEK/glass fiber composite, and another part (blocked) made of ordinary polyamide 66. The blocking/buckling is realized by direct surface contact, and surface/line contact of the...
Hi there,
I am looking for a strong and hard polymer that is moldable. The material is expect to be able to cut into (with some pressure) soft polymer such as nylon. It need to have high strength and stiffness to avoid brittleness break.
I was thinking of PPS, PEEK and fiber reinforced nylon...
Hi there,
I am looking for an alternative injection molding material for ECTFE. Basically need to have "low smoke " feature and comparable mechanical properties.
Thanks,

Hi there,
I am looking for an alternative plastisol to replace current PVC for coating the galvanized pipes. The pipes will go underground so the coating need to withstand soil chemical errosion, should have certain toughness to withstand impact in transpotation and handling, and need to have...
