6-Amino-1,3-dimethyluracil is a high-performance, eco-friendly additive primarily utilized as a critical raw material for PVC heat stabilizers. Engineered to replace toxic heavy metal stabilizers such as lead and cadmium, this non-toxic and green chemical solution ensures superior stability and safety in plastic processing. Its unique chemical structure allows it to absorb ultraviolet rays, providing significantly better weather resistance and aging prevention compared to traditional organic tin or standard calcium zinc stabilizers.
Beyond its role in the plastics industry, 6-Amino-1,3-dimethyluracil serves as a versatile pharmaceutical intermediate for synthesizing drugs with specific biological activities and acts as a toughening agent in synthetic materials. By preventing the thermal degradation of PVC at temperatures exceeding 90°C, it maintains the structural integrity and performance of both hard and soft PVC products, making it an indispensable component for manufacturers seeking sustainable, high-efficiency chemical additives.

It is considered green because it is completely free of hazardous heavy metals like lead and cadmium, reducing environmental impact and meeting strict international health and safety standards.
Due to its chemical structure, it can absorb ultraviolet (UV) rays, which prevents the polymer chain from breaking down under sunlight, thus extending the lifespan of outdoor PVC products.
Yes. While the amount of plasticizer differs between hard (e.g., doors/windows) and soft (e.g., films/leather) PVC, this stabilizer works effectively in both to prevent heat degradation.
It neutralizes HCl released during heating, passivates metal ion impurities, and replaces unstable substituents to prevent the PVC from discoloring or decomposing at high temperatures.
Absolutely. Beyond plastics, it is a key pharmaceutical intermediate used to synthesize drugs with specific biological activities due to its unique structural characteristics.
