Filter elements |
| abstract |
A polyolefin filter for tobacco products and the like was prepared. The extruded element is an open-cell foamed polyethylene or polypropylene having a TPM filtration efficiency greater than 20%. The filter rod can be made by extruding polyethylene containing less than 0.2 moles of a volatile blowing agent per 100 grams of resin at a melt temperature between 130 DEG C. and 150 DEG C., the temperature of the die being between 120 DEG C. and 136 DEG C. Higher melt temperature and die temperature are required for polypropylenes. |
