Dupont Zytel 101L vs. Zytel 101 1

[gorilla1969]

I'll be the first to admit that I am not an expert in plastics and have a question which may be simple in nature. We are re-sourcing suppliers for some knobs used on assorted products we sell. One of the knobs calls out Zytel 101 on the print. One of the potential new suppliers states that they are having trouble locating Zytel 101 and want to substitute it with Zytel 101L (lubricated). I'm not familiar with 'lubricated' plastic types. Can someone educated me on this topic? I've looked on the web and have found little information to help me. Thanks.

101L has a small amount of a low melting point wax added. This aids mainly in release of the part from the mould and may reduce cycle times. It slightly decreases some physical properties.

Does the 'L' version of Zytel have any properties which increase the smoothness (or slickness) of the part. Someone at the workplace stated that he thought 'L' type materials were more often used in applications such as for bearings, etc because they exhibit less friction than the standard versions of the plastic. Since this is for a knob, I'd like to avoid this, if true.

Please let me know if the 'L' type of material has an added or notable slickness.

Thanks again.

It is not a bearing grade and will have minimal effect on surface properties after moulding.
