What is Durometer? Watch & Find Out!

[@SydneyMadueke]

Give these guys a gold medal. Outstanding video. Straight and to the point with clear examples to remove any uncertainties. 5/5

[@bjbenterprises]

Sydney Madueke wow, our favorite comment of the week. 5-stars. Can you please watch and comment on all our KZbin videos please!!

[@scottpiebenga4108]

I'm a life long skateboarder and never understood what the hardness of a wheel really meant. This was really helpful!

[@dingdongmcnugget]

Great video, first thing that came up when I searched durometer and I now feel like I have a way better understanding of what the scales correlate to in the real world. Thanks guys.

[@sephirotic87]

Excellent video, informative yet slightly funny on the right moments to bring up your attention.

[@KRGraphicsCG]

I'm glad I found this video. Very informative, straight to the point. I'm working on a project and knowing what the durometer for the material makes it easier to choose

[@bjbenterprises]

Awesome, glad it helped!

[@KRGraphicsCG]

@@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

[@vrogy]

Excellent, in depth video. Thank you for producing this.

[@flermurmurjumjum765]

This is the best video I have ever seen. I will be contacting them about wheels (safety of, and enjoyment factor) soon!

[@valentinbontea529]

Very useful video. It's easy now to choose the right materials.

[@seagangstab2637]

Exactly what I was looking for! Thank you guy :)

[@mecitech]

great video... is this enterprise still running... I have tried contacting you their website countless times to no avail.

[@bjbenterprises]

Yes, it is best to contact our Technical Sales Team for any material questions: [e-mail]

[@spoe6532]

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.

[@bjbenterprises]

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? [e-mail]

[@pequodexpress]

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?

[@GeahkBurchill]

I am looking for a sample ring on your website. I'm interested in purchasing the material sample chits to have on hand when deciding on a material to use in prop building.

[@bjbenterprises]

Send an email to our technical department - [e-mail]- and we can provide you with samples. Let us know what types of materials you are interested in and we can certainly provide a variety of useful reference samples for future projects. Thanks and best regards. -BJB

[@ittimworld]

Very nice explanation. Thanks.

[@raied14]

Excellent video, I had a concern for a specific design, I got it, it should be 40 shore A (cheers)

[@ParaParagon]

To get a complete overview having shore C included would have been helpful as I am having to deal with a lot of shore C measurements..!

[@bjbenterprises]

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.

[@MrP-rt7gq]

If my silicone says it's shore a hardness is 2, does that mean 20?

[@somedandy7694]

This was exactly what I needed to know. TO THE SHOPPING CART!!!

[@AsitShouldBe]

Very nice video, thanks friend.

[@technogeek9659]

thanks was super usefull to visualise how soft the fleshlight i'm ordering is

[@pistonpistache]

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 ?

[@bjbenterprises]

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.

[@pistonpistache]

BJBEnterprises thanks a lot. i will choose that one so. it is to re-do old insulation rubber parts from a late 60's vibraphone.

[@bomomomo]

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.

[@bjbenterprises]

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. Here is a list of products to consider: bjbenterprises.com/index.php/polyurethanes/castable/semi-rigid/all-purpose/

[@johnevans2553]

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.

[@bjbenterprises]

+John Evans Hi John, thanks for inquiring. I think we can help you out with the application. If you can send an email directly to our Tech Department with pics and info, we would be happy to assist you finding the right material for your alternator mounts. [e-mail]

[@johnevans2553]

+BJBEnterprises Good grief! That was quick.15 minutes must be some kind of record. I will send an email right away. Does it make a difference that I am in the UK?

[@bjbenterprises]

+John Evans :) No problem. We do have a material distributor in the UK, Techsil but can hopefully point you in a direction with regard to material selection. Regards.

[@rissaz7152]

thanks this helped me in picking some longboard wheels😃

[@CarbonGlassMan]

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?

[@bjbenterprises]

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: [e-mail]

[@CarbonGlassMan]

BJBEnterprises Do you have sample pieces for sale? I tried a 78 shore D which felt good and snapped onto the toy fine but broke when taking it back off the toy.

[@bjbenterprises]

We have cured coupons of our various products that can be mailed out for no charge. Simply send an email to [e-mail] and we can get you some samples to evaluate. It sounds like you need a product with a bit more elongation.

[@CarbonGlassMan]

BJBEnterprises I'll send that email Now. I'll use "cured coupons" in the subject.

[@seagangstab2637]

That was beautiful you guys

[@SwimmingUpCurrents]

Thank you! Very helpful.

[@Jonatansimon]

whats better scale to running shoe measurement? a or c?

[@bjbenterprises]

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.

[@euro609]

Great work with all these videos. Very informative. I am looking to make my own phone case for a unique phone I purchase, which there are no options available. I would like to use a material (Similar to otter box or better) for the case that can take a fall of about 4 ft. What would you recommend? Is there a kit with all material included available? Thanks in advance.

[@bjbenterprises]

euro609 because every application is so unique we would typically go through the properties needed for the part with our technical sales team. It sounds like you need a very high impact material but there may be other parameters that need to be sorted out. Have you made a mold before? What will you use for a pattern to mold? What color do you prefer? These are some the questions that will impact the recommendations made. Feel free to contact us at: [e-mail]

[@euro609]

@@bjbenterprises thank you I will be in contact with your sales team very soon to get the proper materials.

[@orionfleming6783]

would a hockey puck be a 40 to 50 shore d? thank you....

[@bjbenterprises]

Hello Orion, a hockey puck would be around 90A, which is very close to 40D. Thanks for your question.

[@orionfleming6783]

do you have a water clear, semi uv resistant polymer of that durometer that you would recommend for casting? or would led light cause it to discolor? thank you for your promptness.

Hello. Please, what should wee use for exemple for a smartphone or camera video case? Soft like 15 or more 5?See you.

[@bjbenterprises]

Yes, a soft cell phone case cover would be around 15A. 5A would likely be too soft and tear easier than 15A.

[@galinouprod2692]

Great video. I'm interested in seeing one about the difference between skin simulation polyurethanes (of which there are many on your website). I cant use silicone for various reasons so picking a suitable polyurethane is important.

[@bjbenterprises]

Hi Kim, we do have many soft Polyurethane systems to choose from. It may be best for you to get some of our cured samples to examine and help make a better decision. You can also contact us directly to explain your application in more detail to narrow down material selection. Note that we have both castable and brushable skin-like systems so this is where application details will help the process. You can send questions to [e-mail]
