STUDY ON THE CLARIFYING ADDITIVES FOR HIGH DENSITY POLYETHYLENE
Keywords:polyethylene, bis-3, 4-dimethyldibenzylidene sorbitol, bis-p-methylbenzylidene sorbitol.
AbstractBis-3,4- dimethyldibenzylidene sorbitol (DMDBS); bis-p-methylbenzylidene sorbitol (MDBS) and the mixture of DMDBS/MDBS (50/50) were studied through optical, thermal, mechanical properties and surface morphology. With the same amount of additive (DMDBS/MDBS mixture and DMDBS) in the material, the results are similar. On the other hand, using an additive mix reduces the cost of production due to MDBS. Furthermore, the additive mixture is used without producing odours. Therefore, the mixture of DMDBS/MDBS (50/50) is chosen.
