This so-called 'commodity' material is actually quite complex, making selecting of the right type a challenge.
Newer specialty slip masterbatches go beyond traditional capabilities to provide greater thermal stability, reliability, and ability to hold COF steady during laminating.
Molders should realize how significantly process conditions can influence the final properties of the part.
