Investigation of the Effect of Titanium Dioxide on Optical Aspects and Physical and Mechanical Characteristics of ABS Polymer

Abstract

Acrylonitryl-butadiene-styrene (ABS) is an engineering polymer with intrinsic yellowness and translucency due to blue wavelength absorption and partial light transmission, respectively. Generally, using titanium dioxide pigment helps to whiten ABS polymer and reduce its intrinsic yellowness. Also, it can impart opacity to polymeric parts. However, it must be considered that this pigment may cause some unfavorable effects in ABS parts. In this article, effects of surface treatment type and content of TiO 2 pigment on optical aspects of a general purpose ABS have been investigated. In addition, physical and mechanical characteristics including tensile strength, izod impact strength and Rockwell hardness of the polymer have been studied. By adding titanium dioxide pigment opacity and whitening index increased and yellowness index decreased. It is important to note that surface treatment type of titanium dioxide pigment had no considerable effect on optical properties of titanium dioxide pigmented ABS polymer. The results showed that arising content of organic and inorganic surface treated TiO 2 pigments up to 0.5% and 1.5%, respectively, causes to increase impact strength and decrease yield stress and maximum strain of Downloaded from pigmented ABS samples. Above these percentages, impact strength decreased due to agglomeration and decreasing inter-particle spacing. Also hardness of all the ABS samples reduced in the presence of inorganic and organic treated titanium dioxide pigments.

Investigation of the rheological behavior of titanium dioxide pigmented acrylonitrile–butadiene–styrene polymer

“…Remarkably, the aforementioned results agreed with the results of a previous author's research 1. The increases in the content of organic and inorganic surface‐treated TiO 2 pigments up to 0.5 and 1.5%, respectively, caused an increase in the impact strength and a decrease in the yield stress of the pigmented ABS samples because of the good dispersion of the pigments and suitable interparticle spacing.…”

“…We investigated the effects of the surface treatment type and content of TiO 2 pigment on the optical aspects and physical and mechanical characteristics, including the tensile strength, Izod impact strength, and Rockwell hardness of a general‐purpose ABS polymer 1. Treating the surface of the TiO 2 pigments improved their weather resistance and dispersability.…”

Evaluation of commercial Mg(OH)2, Al(OH)3 and TiO2 as antimicrobial additives in thermoplastic elastomers

“…However, the technology applied to synthesise additives for use as antimicrobial agents can be expensive. Chemical elements that are already widely used in industrial processing, such as fire retardants magnesium hydroxide (Mg(OH) 2 ), aluminium hydroxide (Al(OH) 3 ) [8][9][10][11], and titanium dioxide (TiO 2 ), used as a whitener [12], have great potential to be applied to polymers for the production of antimicrobial materials [13][14][15][16][17][18]. So, it is worth testing the nontoxic, low-cost, and available additives in antimicrobial polymer manufacturing.…”

Thermal, optical, interfacial and mechanical properties of titanium dioxide/shape memory polyurethane nanocomposites

“…This suggests that the microphase separation of soft and hard segments in SMPU is affected by addition of TiO 2 nanoparticles, and the ordered structures in SMPU are decreased, forming more disordered structures in SMPU. The reasons for this are the interface interaction between TiO 2 and SMPU and steric-hinerance effects affect the aggregation of hard phase in SMPU[30].Furthermore, more intermediate phase is formed between TiO 2 nanoparticles and SMPU matrix, leading to the decrease in miscrophase separation of SMPU. This is because TiO 2 nanoparticles have a huge specific surface area and high surface energy although its content is small.…”
