Sustainable unsaturated polyester resin composite tiles were prepared using snail shell powder by open mould technique. The snail shell powder filler was obtained from snail shell, a domestic waste. The filler characterized for pH (7.61), bulk density (1.33), specific gravity (1.80 g/cm3), refractive index (1.45), oil absorption (5.0 g/100 g), and moisture content (14.01%) was incorporated into the polymer matrix at 0 to 30 wt. % filler content. The tensile, and compressive strength of the tile samples decreased with filler content whereas the impact, hardness, and specific gravity increased with filler content, and were generally greater than those of cured unsaturated polyester resin at any filler content considered. The tile samples containing 15, and 25 wt. % snail shell powder were vitreous while the samples containing 10, 20, and 30 wt.% snail shell powder were semi – vitreous. The low water absorption property of the tile samples makes them suitable for household utilizations in areas such as kitchen walls, floors, backlashes, and shower walls, and should justify the use of low - cost snail shell powder in the composite industry. This will lead to a cost - effective handling and management of snail shell waste thereby, providing a clean environment.

Call for Submissions

We welcome submissions for the coming issue that will be officially published in March 2022. We are committed to providing results of reviewing within two weeks, and publishing the paper within one month from the submission date (subjected to responses by authors). This means accepted papers will be available online even before the issue is published officially.

Publons Partners

Journal of Polymer Science and Technology (JPST) is now one of Publons Partners. This means biodata of reviewers in Publons will be automatically updated once reviewing on articles submitted to JPST is completed (subjected to terms and conditions).

How to promote journal articles

Promoting your journal article is imperative to maximise the exposure, enhance the discoverability and increase engagement with readers and other academics. Together with the publisher, as an author, you can help to promote your newly published articles via the following:
