Comprehensive Investigation of Acrylonitrile-Butadiene-Styrene (ABS) Polymer for Weathering With the Combination of Different Blends of UV Stabilizers, HALS and Antioxidant 2019-26-0169

Plastics (polymers) are nowadays clearly a material of choice in all the application sectors including in Automobile sector. Automotive manufacturer have relied on new technology for vehicular accessories which are all made-up of different polymers. Although these components offer an impressive range of attractive properties, the effect of climatic conditions on the durability and performance of these materials is not fully understood. The degradation/ variation of the mechanical properties of the specimen treated at different environmental/ atmospheric conditions are a primary concern when recommending such a composite for particular use. Generally when these components are subjected to weathering effects, they are prone to underperform. Therefore to improve their properties over time, different kinds of UV stabilizers, Hindered amine light stabilizer (HALS) and Antioxidant are used. However there is a need to study which UV stabilizers is to be used for the automobile applications polymers and what are its percentages? In this context, it is proposed to carry out a comprehensive investigation on degradation due to weathering of ABS polymer with the combination of different percentages of UV stabilizers, HALS and antioxidant. This paper briefly examines the effects of the weathering on the performance and properties of ABS polymer which is most commonly used materials in automobile sector. The use of accelerated weathering techniques to assist in assessing the durability of these product materials is also briefly discussed. The results after weathering and mechanical tests were discussed and optimized the percentage of blends as per the application.
