Thermoplastic Elastomer (TPE) |
||
Underwater pelletizing of all variants of TPE ( TPE-S, TPE-E, TPE-U, TPE-A, TPE-V, TPE-O ) produces very good results. TPE is easy to handle - no processing problems are to be expected. TPE can be processed with standard fillers and pigments and is mainly used in the automotive industry and for medical applications. In micro-pelletizing TPE, pellet sizes of approx. 0.5 mm are currently possible. Advantages The advantage of underwater pelletizing in this field is the good cooling of the pellets in the water flow. For medical applications, a very high level of purity can be achieved. Since also cold water can be used, surface tack can be fully eliminated. Underwater pelletizing produces ball-shaped pellets that do not have any linear adhesion surfaces even after leaving the water flow, as are known from standard cylindrical pellets. Gala systems permit the processing of TPE of a Shore hardness of 0 A through to 75 D - without any conversion. Reasons for preferring a Gala underwater pelletizing system: • Low capital expenditure • Low space requirements • Low energy costs • Low tooling costs • Fully automatic and redundant design • Low sound pressure level < 80 db(A) |
