Nicron® 674DT21 by Magris Performance Materials acts as an effective anti-blocking agent. It is an off-white, high purity, platy, ultrafine talc. It has excellent top-size control. It offers improved HDT, dimensional stability, and aesthetics in high performance plastics and plastic films. It is a highly densified version of Nicron® 674. It is used in thin gauge polyolefin films.
- It improves the impact-to-stiffness ratio in polypropylene and automotive TPOs.
- It flows better than powder grades and disperses easier than compacted grades of micronized talc.
- Nicron® 674DT21 provides efficient nucleation of semi-crystalline polymers such as PE, PP, POM, polyamides and polyesters.
