Properties:
Antioxidant 1098 functions as a radical scavenger and a UV absorber. It captures and neutralizes free radicals generated during oxidative processes, thereby preventing oxidative degradation. Additionally, it absorbs UV radiation, preventing it from reaching and damaging the material.
Stabilization of Polyamide Molded Parts, Fibres, and Films:
Antioxidant 1098 emerges as a paramount solution for the stabilization of polyamide moulded parts, fibres, and films. At concentrations ranging from 0.05% to 0.5%, it exerts its protective influence, countering the degradation threats posed by thermal stress and oxidative processes. By integrating antioxidant 1098, these essential polyamide components gain an extended lease on life, maintaining structural integrity and functionality.
Polyamide Polymerization Enhancement:
Incorporating antioxidant 1098 during the polyamide polymerization phase, within the concentration range of 0.05% to 0.2%, bestows a transformative shield to the polymer’s colour properties. This initial layer of protection becomes particularly significant as the polymer progresses through subsequent fabrication, spinning, or finishing operations. With Antioxidant 1098 as a guardian, the inherent hues of the polymer remain vibrant and untarnished, fostering an enduring appeal in the final product.
Application:
Plastics: Antioxidant 1098 is widely used in the plastics industry, particularly in polyolefins (such as polyethylene and polypropylene) and other polymers. It provides long-term thermal and UV stabilization, enhancing the durability, color stability, and overall performance of plastic products exposed to outdoor environments.
Coatings and Adhesives: Antioxidant 1098 is also employed in coatings and adhesives to protect against degradation caused by UV radiation and oxidation. It helps maintain the appearance, mechanical properties, and integrity of coatings and adhesives subjected to outdoor exposure.
Nylon (polyamide) applications as a stabilizer against degradation caused by heat, light, and oxidative processes. Nylon is susceptible to degradation when exposed to elevated temperatures and UV radiation, which can lead to a loss of mechanical properties and color changes. Antioxidant 1098 helps mitigate these effects and extends the service life of nylon products.
When incorporated into nylon formulations, Antioxidant 1098 acts as a hindered amine antioxidant (HALS), providing protection against thermal degradation and UV-induced oxidation. It functions by capturing and neutralizing free radicals generated during these processes, thereby inhibiting degradation and maintaining the integrity and performance of nylon materials.
Storage Notes: Sealed stored in cold, dry, good ventilated place, avoid high temperature and moist.
