Is Polyurethane Safe For Skin?

This is one of the most frequently asked questions which we come across every time a customer wants to buy a skin hairpiece or ask us to add a poly border. We feel we should discuss the issue at this section so that people do not remain in misconceptions.

Hairpieces are chiefly constructed on two kind of bases-- skin bases and the lace meshes. A skin hairpiece base is actually Polyurethane or Poly, a synthetic element that is produced in thin sheets for the hairpiece industry.

Now this may seem scary to some people who have been using the skin hairpieces for quite some time now and didn’t know that these are chemically produced substances.

Poly is not only used as bases but also as borders. Many a times a thicker poly border is attached around the full perimeter of a skin hairpiece base or only on the sides and backs.

In case of lace hairpieces too, poly borders are recommended since these borders help in better adhesion and easy removal of the hairpieces. Using glue tapes becomes easier with the poly borders.

Now the point is, this material is absolutely safe for human skin. We cannot speak for the poly sheets used in some other commodities but those made for the hairpiece industry are absolutely harmless. 

There is no need to panic or get worried about the health issues only because this is not a natural element. May be the process of production is chemical but after the reactions are over the resultant poly sheet becomes completely chemically inert.

Now, what does it mean by a Poly sheet?

It is a Polymer which is composed of organic units joined together by carbamate links or urethane links.

Just brushing up your knowledge of chemistry.

A Poly is produced by mixing two or more liquids--- isocyanates and polyols.

Polyol streams contain a number of materials like cross linkers, surfactants, catalysts, blowing agents etc. Chain extenders and cross linkers influence the polymer morphology.

Polyurethane Catalysts can be metal complexes based on lead, mercury, bismuth, zinc, tin etc. or amine compounds. Surfactants are kind of modifiers of polymers.

When Isocyanates and Polyol streams are mixed, we get a polyurethane system which is often called only a system.

The best part of this material is that it can be produced so thin that while wearing a skin hairpiece you won’t actually feel that you are wearing something.

These are that smooth and comfortable.
