Standard Grinding. On the other hand, a wide variety of thermoplastics do not require cryogenization processes to become powder. Its high melting points allow it to withstand the ambient temperature plus the friction temperature generated by the mill itself. Depending on the micron size, the pellets turns into powder as the blade mill turns.
