What are the benefits of plasticizers?
This opens up a huge range of possibilities for new applications. One of the main benefits of plasticizers is the durability they confer onto PVC applications, which can ensure high performances for up to 50 years. Without plasticizers, PVC can only be rigid, such as the PVC used in wastewater pipes.
What are plasticizers & how do they work?
Plasticizers are colorless and odorless esters, mainly phthalates, that increase the elasticity of a material (e.g., polyvinylchloride (PVC)). Plasticizers soften the PVC to make it flexible and bendable. This opens up a huge range of possibilities for new applications.
Why are plasticisers used in polymers?
Plasticisers are commonly added to polymers to lower their glass transition temperature and increase their processability, mechanical flexibility, ductility and toughness. 1, 2, 3, 4, 5 They represent a class of usually low-to-medium-high molecular-weight compounds with different polarities that are relatively nonvolatile at ambient conditions.
What is the concentration of plasticizers used?
concentration of pl asticizers used. Among three t ested plastici zers concentrat ion, plasticizers at 2% showed the most effective in plasticiz ing the polymer chains. The addition of plasticizers also reduced the TS and the EM, while increased the EB value of the composite films.
Which plasticizer has the least effect on Op value?
Among these plasticizers used, Glycerol showed the least effect on the OP value compared to the control film. The obtained when combined with the HPMC/BW composite. Thus, HPMC/BW film containing Glycerol would with the least affect the OP of the or iginal film. Density Polyethylene (LDPE).
Does adding a plasticizer increase the free volume of polymer chains?
Adding a plasticizer, increases the free volume available by enabling increased motions in the polymer chains thus lowering the Tg.
