Polymer used in kitchen cutting boards

We have three of them, and my guess is that they're made of high-density polyethylene (HDPE).

Nothing more fancy than a slab of HDPE? The thing is, I need to get the same material as the cutting board in bulk quantities and was worried about pricing.

Pretty much just plain old vanilla HDPE. You may wish to order an engineering sample from the vendor to see if their material will work in your application but, yeah, that's all it is.

When used in an industrial setting, you'd be surprised how much fat you can get out of them at the end of the day!!!

Mostly NYLON moulded.

SOMETIMES Hardwood Timber across grain. Butchers in Indian Subcontinent prefer SAAL wood stumps-- that is a supply chain on its own .After a day's chopping of various cuts-including mincing(KEEMA) he scrapes off 0.5mm layer off top, washes and tilts-goes home. Next morning fresh as ever-no stink at all.

Chinese use their soft Bamboo -hot pressed cross grain -edge up to meet knife . Voids filled with Polyurethane .

I am beginningto produce Cutting boards utilizing Assam Bhaluka Bamboo -5+ year mature ,from near to root stump. Bolted with 2 Tie bolts . Avoiding Hot Press+Adhesives but filling the less-than- mm voids between ~10mm thick strips with hard putty-mostly pozzolana cement. Kind on Knives and easy to keep clean/hygienic.

Maybe commercial sense will force me to use Epoxy to fill voids .

If you want to have a look - please say so. Some Crude samples are available.

And how is your PolyUrethane Foam project doing?

Thanks for the additional facts. Beginning to think not exactly a green product these cutting boards, either synthetic or chopped trees. I will do some further research on indigenous materials based on what you said to prop up my report. Polymer look sexier in a retail enviroment, I think. But last word on manufacturing will depend on costs. About my PU project, I did the basis of design document for a mixing and pouring operation; owners were both interested and amused by the suggested bamboo bedding but deemed it impractical for this latitudes. Thanx for asking.

<depend on costs<How Cheap do you need a Bamboo Cutting Board?--$1 @ ?

Bamboo WonderBed+ WonderChair is Humanity's only source of Rest/Unparalleled Comfort. I can sell you kits @$1>2 FOB ....You do a little assaembly near POS.

A common problem with the white plastic cutting board is that after a few times it is used, when there are knife lines on the surface, molds start to grow. And they are a bit resistant to cleaning with detergents or even with a scrubbing pad. Perhaps if you can add or incorporate a mold inhibitor, that will be just as good, and makes a good selling point.

Epoxy is toxic. It will not pass FDA inspection for food contact.

It's LDPE.

Depending on ability to withstand sharp cutting edges, they might use nylon or polycarbonate, but these would be more expensive than HDPE.

it's UHMW of the hdpe (it means ultra high molecural weight)

Amazing anti-bacterial properties can be incorporated in the 'cutting board' by adding small amounts of 'nano-particle' silver. This technology is now being widely used in paints and surface finishes in Hospitals and hospital clothing. The 'nano-particles' keep the amount of silver required extremely small so cost is low. Look for this technology in all kinds of household products soon.

Noticed the results of many tests over the years that have proved wooden chopping boards to be more hygenic than plastic. These results are only mentioned in woodworking journals, not surprisingly.

I don't think there's a definite answer why, but the micro-structure being inhospitable, and the wicking away of moisture, are two theories.

Reports I've seen suggest wood for fruits/vegatables/bakery and HDPE for meat. Wood supports bacteria growth more than plastic and is harder to sterilize. There are fewer harmful bacteria associated with non-meat products, and wood is easier on the knives.

I think the plastic cutting boards originally got their start in industrial settings. At least this was my experience. To clean up at the end of the day, the cutting boards were scraped, then washed with some of the nastiest chlorine products I've ever breathed, and finally rinsed down with 190° F high-pressure water.

I don't think wood could take that for long. Also, I assume that home plastic cutting boards are intended for the dishwasher. Nasty chemicals and lots of really hot water!

I can't decide for you whether you need plastic, or paper. If you want to see a wide variety of plastics, try www.usplastic.com. They have dozens of different plastic compounds along with some info about their uses. Good luck.

Great site. Thanks
