Study on the Effect of Rare Earth Compounds Additives on the Properties of Natural Latex Films

—Rubber is a material with significant influence worldwide, widely used in various fields. The main challenge for this industry is improving the existing drawbacks of natural rubber and creating diverse, high-performance products. This study aims to incorporate the rare earth compound strontium aluminate with natural rubber latex in the hope of producing products that can enhance some properties of rubber and exploit the phosphorescent capabilities of strontium aluminate for potential applications in research and the production of new products. Through measurements of 100% modulus (M100) and tensile strength at 500% elongation (M500), the results consistently demonstrate improved tensile strength. Simultaneously, aging and swelling tests show that incorporating strontium aluminate into natural rubber latex enhances the thermal and chemical resistance of the products. Additionally, the observation of products using scanning electron microscopy (SEM) and thermal gravimetric analysis (TGA) of the NR/strontium aluminate sample yields promising results in demonstrating the positive effects of combining strontium aluminate and natural rubber latex
