Unfortunately, no plasticizer is perfect, so let's not just focus on the shortcomings of plasticizers.For example, DBP has an excellent plasticizing effect, but the flash point is low, and it is very easy to appear smoke during processing. Perhaps the following solutions can be considered: First, reduce the mold temperature, or add a little DOP to increase the flash point.For example, the use of DBP for shoe materials is to take a f···...
View detailsDOP vs. DOTP: Key Differences for PVC PlasticizersDiscover the essential differences between DOP (Dioctyl Phthalate) and DOTP (Dioctyl Terephthalate), two popular plasticizers used in PVC plastics. Both are colorless, oily liquids with similar molecular structures and weights, but their unique properties set them apart:1. Plasticizing Efficiency: DOP offers slightly higher plasticizing efficiency, providing broader applicability across ···...
SG-8 and SG-5 resin production process is basically the same, the production device is exactly the same. The main difference lies in the additive formulation, polymerization reaction temperature, reaction pressure and so on. The reaction temperature and reaction pressure of SG-8 resin have basically reached the working pressure limit of polymerization kettle, and the reaction requirements are more stringent, and the requirements for ope···...
Cold-resisting plasticizer DOA and DOS are common. Main difference is cold-resisting level.DOA use into PVC soft products,cold-resisting level from 0 to -25 degree.DOS use into PVC soft products,cold-resisting level from -26 to -39 degree.PVC products cold-resisting limit is - 39 degrees Celsius. Need to do modification if lower.Because of poor compatibility with PVC, two products use general between 5-20 total oil. Easy to run oil if u···...
