Melt Density
Accurate melt density data can be difficult to find on a given material since this data is rarely published on a material data sheet. Below is a reference list of common resins used in industry. This list should be used as reference, contact your resins supplier or calculate melt density using a melt flow index machine or your molding machine for more detail.
