In the supposedly high-quality plastic is polypropylene. This is also used in staplers. Of course, you can not directly compare the. Previously I thought that LDPE (Low Density Polyethylene) was used because that was on the package. But according to customer service is by polypropylene. There was the LDPE probably only the packaging meant. In principle, no matter from a high-quality cutting board I expected more.
The original price I find just plain rude. The price here on Amazon was least adapted (as of January 2013) and is at least roughly realistic. But the Culinario for 7 euros seems to be just as good, only I do not know what use the plastic. But he can not really be much softer than that of Silit. Non-slip, it is definitely.
Who wants to have a high-quality plastic cutting board, should better buy HDPE. Although there are level differences here. The then scratch not even with cheese. My mother has a cutting board for 10 years of WMF and there are really only very delicate surface scratches present. That's what I call normal for a quality board. But using what material WMF with the current models do not know. They would have to ask first. The have at least different. I'm not sure whether that are so good to me still. But there are also other manufacturers.
The Silit I have at least already after just one application for deep scratches. This is not normal for a supposedly high-quality cutting board. That's just at the boards for 8 euros. If Silit the plastic used already referred to as "quality", I imagine the question what they are doing with their pans. Where I have been very happy with my.
By design, it's okay. Therefore, and only therefore, I forgive at least 2 stars. Everything else is a big lie. These same characteristics have some 8 euros boards also. Silit should the customer time yet another cutting board offer that is really high, then need not make any false promises in this board. To decide what he wants and if he ever wants to eat with the way some plastic the customer, but can it save his blades extremst. This makes butter also.
And no, it does not have to be equal to Titan as some reviewers here my exaggerated.
Edit 02/11/2013
After almost a year now, I can abgewinnen the board at least positve that I can not see any discoloration to the naked eye. I do not know if this is at all cheap boards too. When I go directly to the board with the nose, I can only hear a really quite delicate melon scent. At least I feel that way. However, I must stress that I cook only relatively little. Mainly I cut out bread, cheese and vegetables, such as tomatoes. The many scratches the surface is much rougher and the bread no longer slips now.
