@@bjbenterprises I'm looking at your FD-60 resin for helmet making and hopefully at 4mm, it should be fairly flexible. And great for rotocasting. I'm also reading up on your TC-808 and thin spots at 5mm should have some flex. I don't know how it will react to fillers such as fiberglass powder to increase its strength and hardiness

Thank you so much for this video. For treads with gear teeth in them that need to be able to bend around a 1.2' diameter, which Durometer would you suggest? Overall thickness of the tread is 1/4 inch with an 1/8th being the tooth side and the other flat.
@bjbenterprises7 жыл бұрын
I'm imagining a robot or tank tread on small scale? I would probably suggest something around 60-70A. You get a lot of tear strength as you start to hit 60A, which is similar in Durometer to a common Auto Tire, while maintaining flexibility. We've also seen a tank-tread style bicycle drive-wheel set up where they were using a 85A durometer for best wear resistance. The thickness of the tread, diameter of the cog, and application will all play a part on the ideal durometer. You could contact us for some cured samples to see what feels right for your potential part? info@bjbenterprises.com

I need to source a hard rubber block (about 30cm x 30cm x 4cm) for use in leatherwork as a firm, solid punching block that will not damage sharp tools. My research tells me that I need a durometer rating of 40D to 50D, about the hardness of black caster wheels, maybe a bit harder. What search terms would be helpful in sourcing this rubber block material?

Hello, different industries tend to use different Durometer scales. In our typical class of casting material systems, we usually only deal in the Shore A and Shore D (occasionally OO) as an industry standard. We honestly do not get much call for Shore C. Thanks for the comment.

I've travelled the whole internet to find this ! thanksalot. So a resistant rubber like a tiler mallet would be what ? 70/80 shore A ? Is shore significant to shock resistance ?
@bjbenterprises8 жыл бұрын
Glad you finally found it! A mallet is indeed around 70-80 Shore D. If by shock resistance you mean absorbing vibration or impact, yes, lower durometer will absorb more. However, you gain more toughness and tear strength as you increase Durometer (typically). We have many customers who make engine vibration mounts or chassis mounts using 60-80 Shore A urethanes for example.

Very good information. Would you please advise what hardness/shore value of a polypropylene plant container will be? Is it still Shore D 70? I would like to make one and cut open the vertical edge so that it has some elasticity to attach to the bottom of my plant. Thanks for your great info.
@bjbenterprises7 жыл бұрын
Hello, yes a Polypropylene material is roughly Shore 70D. Depending on the application or part requirements, you might even go lower in durometer (60-65D) to increase elongation and toughness if required.

Hi, I need some help please. I am trying to mould some small rubber blocks used in a vane type shock absorber inside a motorcycle engine. Six blocks with three hardened steel vanes in between them. They would need to stand up to around +110C and down to -35/40C. These shock absorber blocks control movement of a fairly heavy alternator rotor. What would I be looking for to do this? I have a steel mould made.

I have a question. I need to make a part for a toy Airsoft gun that broke and I can't buy the part. This may be impossible since you haven't seen the part, but it's a clip under spring tension and is flexable enough to snap it over the rest of the toy, but hard enough to hold it's shape and stay on the area it's snapped on to. I was thinking Shore D about 75?
@bjbenterprises9 жыл бұрын
That sounds about right, but you may need to consider things like elongation, flex modulus, and a couple other points. Feel free to email us a picture of the part and we may be able to answer this better for you: info@bjbenterprises.com

whats better scale to running shoe measurement? a or c?
@bjbenterprises10 жыл бұрын
The most common measurement in our industry for elastomers would be the Shore A scale. Shore C is not a commonly used scale. Shore C has the same presser foot as the Shore A but higher spring force. You can certainly use it for harder elastomers but you would find more familiarity with the Shore A scale in our industry.
