Rubber Antioxidant FAQ Section
Q: What is the recommended dosage of Rubber Antioxidant in rubber compounds?
A: The typical dosage ranges from 0.5% to 3% of the total rubber compound weight. The exact amount depends on the specific rubber type, application requirements, and environmental conditions. For best results, we recommend conducting small-scale trials before full production.
Q: How does Rubber Antioxidant protect rubber products?
A: Rubber Antioxidant works by interrupting the oxidation chain reaction that causes rubber degradation. It donates hydrogen atoms to stabilize free radicals and decomposes peroxides that form during oxidation. This dual action mechanism significantly slows down the aging process, maintaining rubber's elasticity and mechanical properties for longer periods.
Q: Can Rubber Antioxidant be used in food-contact rubber products?
A: Yes, we offer special food-grade Rubber Antioxidant formulations that comply with FDA and EU food contact regulations. These versions are free from harmful substances and have been tested for migration and extraction safety. Always check the certification documents for specific product approvals.

Additional Rubber Antioxidant FAQ
Q: What's the shelf life of Rubber Antioxidant products?
A: When stored properly in original packaging at temperatures below 30°C and relative humidity below 70%, our Rubber Antioxidant maintains its effectiveness for 24 months from production date. Always check the batch code for exact manufacturing date.
Q: How does your Rubber Antioxidant perform in outdoor applications?
A: Our specially formulated Rubber Antioxidant provides excellent protection against both thermal oxidation and weathering effects like UV radiation and ozone exposure. For outdoor applications, we recommend combining it with appropriate UV stabilizers for maximum protection.
Q: Can Rubber Antioxidant be used with other rubber additives?
A: Yes, our Rubber Antioxidant is compatible with most rubber processing aids, accelerators, and other additives. However, we recommend consulting our technical team when using with certain specialty additives to ensure optimal performance and avoid any potential interactions.
