Hydrolysis-Resistant Light Stabilizer
Overview
Hydrolysis-Resistant Light Stabilizer is a critical additive for polymers exposed to harsh environmental conditions. It combines UV stabilization with hydrolysis resistance, making it ideal for applications where materials face prolonged sunlight and moisture exposure. This stabilizer is widely used in industries requiring long-term durability, such as automotive, construction, and agriculture. Its ability to prevent polymer degradation extends the lifespan of products, reducing replacement costs and environmental impact.
Physical and Chemical Properties
The stabilizer typically appears as a white to light yellow powder or granules, with a density of 1.1-1.3 g/cm³. It is soluble in organic solvents like acetone and toluene but has low water solubility, ensuring minimal leaching in wet environments. Its thermal stability allows it to perform under high temperatures, while its molecular structure effectively absorbs UV radiation and neutralizes free radicals. These properties make it a versatile solution for diverse polymer matrices.
Main Applications
Hydrolysis-Resistant Light Stabilizer is primarily used in automotive coatings, outdoor plastics, and agricultural films. In automotive applications, it protects exterior parts from UV-induced fading and cracking. For agricultural films, it ensures longevity despite constant exposure to sunlight and moisture. Industrial plastics, such as those used in construction, also benefit from its dual protection, maintaining structural integrity over time.
Safety and Storage
Handling this stabilizer requires basic safety precautions, including gloves and goggles to avoid skin or eye contact. Inhalation of dust should be minimized by working in well-ventilated areas. Storage conditions are straightforward: keep the product in a cool, dry place, away from direct sunlight and moisture. Proper storage prevents clumping and maintains efficacy over long periods.
B2B Procurement Guide
When procuring Hydrolysis-Resistant Light Stabilizer, prioritize suppliers with certifications like ISO or REACH compliance. Verify the product's purity and compatibility with your specific polymer formulations. Request samples for testing before bulk purchases. Pricing varies by quantity and supplier, but expect a range of $20-$50/kg. Long-term contracts may offer cost savings for large-volume buyers.
