4X Gold Silicone Mold Rubber is soft with extremely high tear strength and is intended to be used for very intricate designs. This rubber is designed for hand cutting method. If you wish to use powder separation method, use more powder than you would with other  stiffer, lower strength products. If you do not use extra powder, you will not obtain good separation. Very high pattern finish.

We recommend that you use stainless steel mold plates as this product tends to adhere more strongly to aluminum plates.
