WORKING WITH URETHANE RUBBER: Casting Urethane / Polyurethane Rubber in a silicone mold 

Nice video And pu rubber is one of the best shock absorber rubbers. 🤗

Helpful video, thank you! Look forward to watching more.

This is sooo helpful! Thank you!!

Very nice video, thanks

Great tutorial, thanks a bunch for sharing! I'l be casting some vintage skateboard parts before long - God bless :)

Does this rubber dissolve on the chemicals like gasoline? Can motorcycle parts be made with it?

Great video, thank you

Do you know the rubber like thing they use for the heads of action figures

Is the Urethane Rubber grippy enough to cast it in the form of tires for a robot?

What do I do if I want a matte finish? Is it the pigment or the PU that determines the finish?

What hardness did you use of the Urethane rubber?

Great tutorial.. Just out of curiosity, can it be used to cast items leaching into a mould made of "Blue Stuff"?..

How much does it cost to cast one of the pu circles? Wondering if it would be cheaper to buy them or made them? 🤔

Sir, what is the most suitable material for making shoe soles? Silicone rubber (with high shore) or polyurethane rubber? What is the most similar material to the sole of Dr. Martens' boots? Thank you very much! Nice video!

i watched at 2021... covid time. thanks for your lecture sir. pls continue

thanks for the vedio

how strong is this material? because I want to make a mold that can be pressed, please help me

Do you think we can use this to make shoes outsoles? Would it be resistant enough?

Well done! We’re thinking of using this material for our skull-shaped dumbbells that you see in my profile pic to the left of this comment.... They were made with concrete in latex molds. Do you think this complex skull shape can be casted with urethane?

Thank you! Am going to try to recreate the Marc Jacob’s clear sole boots

is this the type of rubber that people use for shoes?

Isn't polyurethane toxic?

Is this urethane rubber resistant to salt water?

Could you mould tank tracks in 1:76 scale using this method.

can you use polyurethane rubber on water based base clay

Can you cast tank tracks using this method? What is the minimum thickness you can cast with this stuff? I have a few kits that are very old and the rubber of the tracks has gone very brittle and snapped. I have been searching for a method of reproducing them for my models since they look silly without tracks, lol.

Love it :p

Thanks for the video, I want to make a key chain that have 2 colors is that possible or the colors will get mixed?

Do you think I could make shoe soles using this method?

Anyone ever tell you that you look like a young Buzz Aldrin? I'm in Ireland and I have never heard of the supplier you mentioned. Smooth on has a good range but are expensive. There are local suppliers of other products, both equally good quality and much cheaper.

Is there a hard rubber you can cast?

is one of those part a and b the hardner?

Hey there, I found this video because I've gotten into toymaking with a flex rubber, I absolutley love the medium and it's so fun to cast and mess with. I had a SMALL question that I can't seem to find anywhere else... how do I fix bubbles and imperfections on my rubber casts, ON the actual casts? I don't own a vac chamber so I've been extra careful with my pours, and its working great, but I'd love to somehow salvage some pieces that didnt turn out as good / have big gaps. Can you heat or melt leftovers? Or do like, a paintover or something with another mix of it? I'm just curious how people who work with rubber fix an issue like a gap or bubble hole or have any hacks. A lot of issues I run into is accidently not checking feet or platforms of my toys for bubbles, so when I pull them out, the feet have some gaps. I just dont know exactly the 'best way' to fix that *and* get a color match, other than making a new batch, holding the figure pefectly up for an hour (cure time) while I wait for it to cure? TYSM, wonderful video!

Great video!! Do you happen to know how one can make poron foam please?

One quick question. Did you need to use any kind of release agent, or does the urethane rubber not stick to silicone either way?

Hi! Thank you for this video! I’m pretty sure this is the exact form of liquid rubber that I would need for my project! I tried finding the polytek PT-Flex 70 casting rubber but it’s all on back order and the link in the description takes me somewhere else 😢 Do you know what would be a good alternative to use that would yield the same result (colorable as well)?

Have you had any success painting polyurethane rubber?

Great video, thx. Is the PT-Flex 70 rating on the Shore A? What is the hardness rating for silicone rubber?

Like the scales. Got a link? What's their max allowable weight? Thx much 4 posting vid.

Cool. How would it go in a marine setting?

Can we make outsole shoes with this PU rubber ?

can u help in casting nitrile rubber bellow for us

Hi there. Thanks for the video! When I try to cast urethane rubber in a silicone mold, the piece totally cures except for the surfaces that contact the silicone. They are forever tacky and unuseable. Any idea how to mitigate this problem?

Where to get it when located in Europe ?

How hard is Smooth-On vytaflex 60?

How did you add the colour? I'm looking to get a metallic silver effect on some pieces

Can you tell me the name of this chemical?

Seriously, you needed to show his to put all the elastic bands on?

Could you send me a sample to the USA?

What the hardness

Could you make shoe soles out of it?

Hi, Did you use mold release? looking for a release that removes polyurethane from silicone. Thanks
