The present invention is directed to polymer blends having controlled flow properties. The polymer blends can be useful in various applications including bonding systems and additive delivery systems, which can provide durable binding and/or delivery and/or affixing of additives. The polymer blends can include at least two different components, at least one being a polymer component having a higher molecular than the other of the components. When heated to an activating temperature, the resultant blend exhibits desirable flow or wet out properties without applied pressure. Despite the controlled flow properties, the blends do not exhibit blocking or fusing properties typically associated with high flow polymer materials. |
