Ammonia-free rubber & latex
Natural rubber latex (NRL) is an essential material used in various industries for its unique properties. However, NRL faces significant challenges in preservation and stabilization, primarily due to microbial degradation and coagulation. Traditional methods of addressing these problems are often based on harmful chemicals, posing risks to human health and the environment. Several researchers are investigating environmentally safe methods to preserve and stabilize NRL to address these challenges. As a result, AFLatex Technologies has emerged as a promising solution.

NRL, derived from rubber tree sap, is known for its exceptional elasticity, tensile strength, and abrasion resistance. It is extensively used in the medical industry, the automotive sector, and for consumer goods. Nevertheless, preserving and stabilizing NRL is challenging due to microbial degradation, leading to spoilage and material loss. Premature coagulation during storage complicates matters, making it unusable. Traditional methods use chemicals like ammonia and thiurams, which are effective but risky due to toxicity and pollution potential.
AFLatex technologies represent a significant advancement in the preservation and stabilization of NRL through environmentally friendly approaches. These technologies aim to reduce reliance on harmful chemicals while maintaining the quality and usability of NRL.
Researchers at AFLATEX Technologies developed two novel liquid latex preservation methods without ammonia or harmful chemicals. One method uses dodecyl benzene sulfonic acid for stabilization and preservation. The other employs ethoxylated tridecyl alcohol for stabilization and hydrofluoric acid for preservation. Both formulations enhance rubber’s mechanical properties, ensuring worker safety and environmental friendliness.
In practical applications, AFLatex offers eco-friendly adhesives with varying rubber content for domestic (35%) and industrial (60%) use. Their latex formulation with high dry rubber content has also transformed glove manufacturing, ensured superior performance, and reduced allergenic protein content to 45%.
