Frequently Asked Questions
Q
What is DILAURYL HYDROGEN PHOSPHITE (CAS 21302-09-0)?
DILAURYL HYDROGEN PHOSPHITE (CAS 21302-09-0), marketed as YIHOO AO12, is a phenol-free phosphite antioxidant in the form of a colorless transparent liquid. It is widely used as a thermal stabilizer and antioxidant in polymer processing and lubricant formulations.
Q
What are the main applications of YIHOO AO12?
YIHOO AO12 is primarily used in polyolefin and PVC materials to preserve color and transparency. In PVC systems, it enhances anti-precipitation performance and initial whiteness. It is also used in lubricating oil formulations as both an antioxidant and an extreme pressure additive.
Q
Is YIHOO AO12 an eco-friendly product?
Yes. YIHOO AO12 is a phenol-free phosphite antioxidant, making it an eco-friendly alternative to conventional phenolic antioxidants. Its formulation is designed to meet modern environmental requirements while delivering excellent thermal stability and processing performance.
Q
What are the key technical specifications of DILAURYL HYDROGEN PHOSPHITE?
The key specifications include: Phosphorus content of 7.4%, refractive index (25℃) between 1.4400–1.4550, specific gravity (25℃) in the range of 0.880–0.920, and an acid value of ≤8.0 mg KOH/g. These parameters ensure consistent quality and performance in end applications.
Q
How does YIHOO AO12 benefit PVC processing?
In PVC systems, YIHOO AO12 significantly improves anti-precipitation performance and initial whiteness of the material. Its excellent thermal stability helps maintain the integrity of PVC products during high-temperature processing, resulting in better color retention and overall product quality.
Q
Can YIHOO AO12 be used in lubricating oil formulations?
Yes. YIHOO AO12 serves a dual function in lubricating oil formulations — it acts as both an antioxidant and an extreme pressure (EP) additive. This dual role helps protect lubricants from oxidative degradation and extends the service life of oil products under high-pressure operating conditions.
