Polyamide Plastics (PA)(Nylon) |

Underwater pelletizing produces good results for all variants (Nylon 11, Nylon 12, Nylon 6, Nylon 6/6, even non-extracted). Products are hygroscopic. Products have a high crystalline melting point. In micro-pelletizing Nylon, pellet sizes of approx. 0.8 mm are currently possible. Advantages The advantage of underwater pelletizing Nylon is the round or elliptic pellet shape and the resulting free-flowing properties of the product in the subsequent use. Another benefit of using Gala pelletizing systems for Nylon is the closed system, preventing any exposure of the product to air. The noise emission level can be minimized by selecting an appropriate dryer. Die plates with specially designed heat conduction for an ideal heat transfer at the interface have considerably extended the window of applications. Reasons for preferring a Gala underwater pelletizing system: • Low capital expenditure • Low space requirements • Low energy costs, cost-efficient water preparation since pellets can be discharged at >90°C • Low tooling costs • Fully automatic and redundant design • Low sound pressure level < 80 db(A) For these applications, pelletizing systems are available for installation downstream of extruders but also for use with reactor lines with melt delivery pumps. |
