Polylactic acid (PLA) viscoelastic properties and their degradation compared with those of polyethylene
(2015-12)
Polyethylene (PE) films are widely used in packaging. PE is a thermoplastic manufactured from nonrenewable petroleum resources. Due to its non–biodegradability, its films have posed serious pollution problems e.g. visual ...
UV Absorption and dynamic mechanical analysis of polyethylene films
(2014-12)
Photooxidative processes that lead to chain scission and chain linking in polymers play an important role in polymer degradation. These processes are induced by both ultraviolet (UV) and visible light absorption. The ...
Determination Of The Density And The Damping Properties Of Polyethylene (Pe) And Polylactic (Pla) Films Using Dma
(2013-08)
Damping which is an effect that tends to reduce the amplitude of oscillations in an oscillatory system is significant in components under high dynamic loads especially in general mechanical engineering. In this study, ...
