Frequently Asked Questions
▶Irganox 1010 vs 1076 — which should I choose?
Choose 1010 for maximum long-term thermal stability; choose 1076 when lower volatility and better compatibility with semi-transparent or thin-section applications matter.
Irganox 1010 vs 1076 — which should I choose?

▶Why is the phenolic : phosphite ratio typically 1:2?
The 1:2 ratio matches the stoichiometry of the two mechanisms: one phenolic radical-trap consumes roughly twice as many peroxide species as a phosphite decomposer, so doubling the phosphite component gives optimal synergy.

▶Which antioxidants are FDA food-contact compliant?
BHT (21 CFR 178.2010), Irganox 1076 (21 CFR 178.2010), and Irgafos 168 (21 CFR 178.2010) are all FDA-listed for food-contact polymers at specified use levels.

▶What is the difference between DSTDP and DLTDP?
DSTDP (distearyl thiodipropionate, C18 alkyl) has higher MW and better long-term stability at elevated temperatures, while DLTDP (dilauryl thiodipropionate, C12 alkyl) is lower-cost and suited for moderate-temperature applications.

▶How do I validate antioxidant performance in long-term thermal aging tests?
The standard approach is oven aging per ISO 188 or ASTM D573 (rubber) or ISO 4577/EN 1296 (plastics), tracking tensile retention, elongation at break, and color (ΔE) at defined time/temperature intervals.

▶What antioxidant grades are commonly specified in the Indian market?
Irganox 1010, 1076, and Irgafos 168 dominate Indian polyolefin compounding; Songwon equivalents (Songnox 1010, Songnox 1076, Songxtend 168) are widely used as cost-competitive alternatives.

▶What is the maximum permitted level of BHT in food-grade applications?
