Light Stabilizer FAQ Section
Question: What is the typical shelf life of Light Stabilizers?
Answer: Our Light Stabilizers typically have a shelf life of 24 months when stored in their original, unopened containers at temperatures below 30°C (86°F) and protected from direct sunlight and moisture. For opened containers, we recommend using the product within 12 months for optimal performance.
Question: Can Light Stabilizers be used in food-contact applications?
Answer: Yes, we offer specific grades of Light Stabilizers that comply with FDA and EU food-contact regulations. These specialized formulations are designed for applications such as food packaging and kitchenware. Please check the product specifications or consult our technical team for appropriate grade selection.
Question: How do I determine the optimal dosage of Light Stabilizer for my application?
Answer: The ideal dosage depends on several factors including polymer type, thickness of the material, expected service life, and environmental conditions. As a general guideline, most applications require 0.1-1.0% by weight of Light Stabilizer. We recommend conducting small-scale trials to determine the exact amount needed for your specific requirements.
