Anti-Oxidant

Overview
Anti-oxidants are chemical additives that prevent or slow down the degradation of materials caused by oxidation. They protect polymers, rubbers, fuels, lubricants, and food packaging materials from thermal and oxidative damage, extending product lifetime and maintaining performance.

Key Properties

• Inhibit oxidation reactions caused by heat, oxygen, and light

• Prevent polymer degradation, discoloration, and brittleness

• Enhance thermal stability and mechanical durability

• Extend shelf life and long-term performance of products

• Available in primary (radical scavengers) and secondary (peroxide decomposers) forms

Examples of the Item

• Phenolic Anti-oxidants — hindered phenols, widely used in plastics and rubbers

• Phosphite Anti-oxidants — protect during processing, act as peroxide decomposers

• Thioester Anti-oxidants — provide synergistic long-term stability with phenolics

• Aminic Anti-oxidants — effective at high temperatures, used in lubricants and fuels

Applications

• Plastics & Polymers — prevent thermal aging in PE, PP, PVC, and engineering plastics

• Rubber & Elastomers — extend durability in tires, seals, and hoses

• Adhesives & Coatings — improve stability and resistance to yellowing

• Lubricants & Fuels — protect against oxidation and sludge formation

• Food Packaging — maintain integrity of films and prevent spoilage (food-grade antioxidants)

Supply Options

• Grades: Industrial, High-purity, Food-grade (depending on application)

• Forms: Powder, Granules, Liquid concentrates

• Compliance: FDA, EU, RoHS, REACH (depending on type and region)

Note: The selection of antioxidants should consider polymer type, processing temperature, and end-use requirements.
