Parafinele sunt ceruri petroliere care constau aproape \u00een \u00eentregime din hidrocarburi saturate normale \u0219i cantit\u0103\u021bi mici de hidrocarburi ramificate. Ele formeaz\u0103 cristale mari, sunt solide, au str\u0103lucire \u0219i fragilitate, sunt transparente sau albe.

Cerurile microcristaline<\/h3>
Cerurile microcristaline sunt lipicioase, amorfe, moi, maleabile, transparent \u0219i cu un punct de topire mai ridicat dec\u00e2t parafinele. \u00cen compozi\u021bia lor, pe l\u00e2ng\u0103 hidrocarburile normale, ele con\u021bin, de asemenea, o cantitate semnificativ\u0103 de hidrocarburi ramificate \u0219i ciclice.<\/div><\/div><\/div>[\/vc_column][\/vc_row][vc_row][vc_column][vc_empty_space height=”10px”][\/vc_column][\/vc_row][\/vc_section][vc_row][vc_column][vc_empty_space height=”120px” el_class=”vc_mobile_space_20″][\/vc_column][\/vc_row][vc_row equal_height=”yes” content_placement=”middle” el_class=”mobile-flex-right-left”][vc_column width=”5\/12″ el_class=”padding-right-30 padding-left-30 double-border”]
