LIGHT TRANSMISSIVE FOAMED POLYMER SHEET AND METHODS FOR MAKING THE SAME |
摘要 |
<p>In some embodiments, a foamed polymer sheet comprises: a polymeric material and cells located in the polymeric material. The cells have a size distribution, D90 of greater than or equal to 300μm and the sheet has a light transmission of greater than or equal to about 5%. In another embodiment, the cells have an average diameter, as measured along a major axis, of about 1 mm to about 4 mm, and the sheet has a light transmission of greater than or equal to about 5%. In another embodiment, a method of making a foamed polymeric sheet comprises: combining a blowing agent with a polymeric material to form a mixture, nucleating bubbles in the mixture, and cooling the mixture. The mixture is at a sufficient temperature and the cells have a sufficient cell size such that the sheet has a light transmission of greater than or equal to 10%.</p> |
