                                                     Sap is collected from Rubber Trees (Hevea Brasiliensis) which is then strained and mixed with                              Abrasion resistant.
                                                     Formic Acid, causing the sap to coagulate into a thicker sludge. The sludge is then rolled to                              Elastic.
                                                     remove any excess water, washed to rid it of any left over Formic Acid and put aside to dry.                               Water resistant.
                                                     Once dry the rubber sheets go through quality control and get packaged to be shipped to differ-                            Insulator.
