4 KPEL (TPC-ET) KPEL is first national TPEE produced by KLN PLASTICS. Thermoplastic Polyester elastomer, which is a TPE based engineering plastic, has rubber-like properties with greater properties, thermal stability, chemical resistance and UV stability. KPEL Thermoplastic Polyester Elastomer KPEL consists of hard segmented and soft segmented block copolymer. Hard segment is crystalline polymer Polybutylene terephthalate (PBT), and soft segment is amorphous polyether. Due to these structures, KPEL has the same properties and stability of engineering plastic, along with rubber-like flexibility. (CH2CH2CH2CH2)X m n [ KPEL Molecular Formula ] 7

In addition, KPEL for airbag cover features the aesthetic surface quality, providing the highest sensitivity quality for passengers to drive in comfort TPU: 4D - KPEL : 4D KPEL blow molded products are used in applications such as CVJ boots or bellows, which are used under harsh environments due to their high melt viscosity and excellent durability. Superior bending resistance and hinge fatigue properties show excellent material retention even when the blow molded moldings are deformed by torsion. It is also excellent in heat resistance and chemical resistance, so it can be used even when used with various types of grease and oils.

10 INJECTIN CNDITINS & HANDLING PRECAUTINS KPEL is an engineering elastomer, which has similar performance to rubber, while the processing conditions for product molding are similar to those of ordinary crystalline thermoplastic resins, making it easy to process with the usual injection molding aids used for molding crystalline resins. CNDITINS F INJECTIN MLDING PRECAUTINS IN MLDING PRCESS Injection speed can vary greatly depending on the form of the product, but KPEL has a relatively high rubber property even in the molten state compared to the polycrystalline resin. When the injection speed is set high, the melt absorbs the injection pressure It is advantageous to set it lower than other resins because the state of the melt is excited and can act as a disadvantage to the product design and condition setting. In addition, in case of thin product, the cooling rate in CAVITY The injection speed should be relatively fast. In case of a thick product, if the injection speed is fast, surface defects such as flow marks and jetting may cause the product to be a critical defect. When using a screen filter for mixing or other purposes in a barrel during extrusion, 6 or 12 mesh is suitable.

Usually, after about 2 hours from the opening of the bag, the moisture content becomes more than.1wt% After drying for 2~4 hours at 11 C, you can get good quality products. KPEL has a very low melting point compared to other thermoplastic resins, which can cause defects on the product surface when mixed with other resins. In order to prevent this, we need clean management of the expectation, prework FEEDER and BARREL, and occasionally screen washing. Also, using SCREEN FILTER between DIE and BARREL is effective for eliminating unmelted material and impurities. PLYMER MELT It is also advantageous in terms of flow uniformity. However, in this case, care must be taken to avoid excessive pressure build-up within BARREL
