Thanks for the helpful feedback. Biocompatibility is an issue here that I probably should have mentioned earlier. The "make your own" suggestion might be a good choice because we can control the process tightly and know what is in the product. I'll investage ...

I'm looking for a hydrophobic coating that I can apply to polyester acoustic mesh. The ideal solution would be either a spray or dipping process. Any suggestions?

Thank you for the suggestions. We will take a look at these cleaners. We are tentatively moving forward with Liquinox and Crystal Simple Green.

Unfortunately we cannot change materials - we have parts in hand the prototype tool is retired. The part is a single use medical device that does experience mechanical loading. If the device cracks it could cause an infection. So, I'm nervous about IPA. I will consider putting some parts on...

Thanks for the input so far. IPA is not recommended for PC because it can cause crazing, cracking, and other damage. I'm not sure how real this risk is. The oakite was recommended by our plastics supplier for PC. We do three rinses including an ultrasonic soak for 5 minutes. Any other...

I'm tyring to find a biocompatible cleaner for a polycarbonate medical device component. We have recently failed ISO-10993 irritation testing on parts cleaned with Oakite 61B. We are suspecting the cleaner. Any help you can provide would be helpful. Thanks.

Thanks for leads. I checked the Medical Design website, which led me to the ides.com website. That is great plastics search site. I think I've got it from here. Thanks.

Hello, I am searching for USP Class VI plastic resin suppliers and I'm struggling to find good options. GE and DOW have a few resins available and there are many food grade options out there. I am looking specifically for LDPE and HDPE resins. Can someone point me to a listing of medical grade...

I am new to injection molded medical devices. I am designing a plastic part that will go inside a person's mouth. The part must satisfy the ISO 10993 biocompatibility standards (cytotoxity, sensitization, and irritation). I would like to start by doing some prototype molding for clinical...

I will contact them. Thanks. Any other recommendations?

Thanks for the feedback so far. Here is some additional information ... The controller will drive a fuel cell system component. Prototype quantities will be several hundred units. Hall sensors are adequate for speed control in this application. 1 kW and 20 Krpm are real. I'm not interested in...

I am located in Tempe, AZ. However, I am willing to look at all domestic suppliers. -SK

Hello, I'm looking for an automotive brushless dc motor controller vendor. The controller will be less than 1kw, operate a small motor at 20,000 rpm. The controller will operate at up to 450 VDC. Operate on hall sensor feedback. Must have CAN control capability. The vendor must be capable of...

Hello, I am encapsulating an electrical coil in PPS ("Ryton") to seal it from a harsh operating condition that includes hot water. I need to pass the electrical hookup wires through the plastic. There must be a very good bond between the wire insulation and the plastic to prevent electrical...

This is an interesting idea. Can you point me to supplier or a website?
