Raw material preparation:
According to the conditions those required by the customer, arrange for internal production of TPE / TPS and set up schedules. Using the material specified by the customer with a specific ratio of SEBS + SBS or a single type of SEBS to produce TPE-S particles.
Put SEBS + SBS into the open type drum and stir evenly. Generally, the polymer will be softened owing to heat generation itself during heating and mixing, so it can be easily mixed with fillers and processing oils and passed through a twin screw extruder for kneading then the crystals will be filtered and granulated from water into TPE / TPS particles.
Water must be removed and dried up for TPE-S particles, and then screened by visual appearance and QC inspection for physical property then pack it up for stock.
