Polymers have become a necessity in virtually every aspect of modern life, and recent advances in their production and processing have further broadened the use of plastics, and in some applications, polymers have even replaced other materials such as glass, metal, paper and wood.
⚠️
The performance of polymer materials can become degraded over time — including yellowing, decrease of relative molecular mass, surface cracking, and loss of luster — due to their structural features and exposure to heat, light, oxygen, ozone, water, acid, alkali, bacteria, enzymes and other external factors. These degradations also affect impact strength, tensile strength, elongation and other mechanical properties, which impacts the normal use of polymer materials.
✅
The anti-aging of polymer materials has become a critical challenge for the polymer industry. Among the various methods to improve anti-aging performance, the most effective and widely adopted approach is adding anti-aging additives — preferred for their low cost and compatibility with existing production processes without requiring any changes.

Frequently Asked Questions
Q
What are polymer anti-aging additives and why are they important?
A
Polymer anti-aging additives are chemical compounds added to plastic materials to prevent or slow down degradation caused by heat, light, oxygen, and other environmental factors. They are important because they help maintain the mechanical properties, appearance, and structural integrity of polymer products, significantly extending their service life.
Q
What is the difference between UV absorbers and light stabilizers?
A
UV absorbers (such as YIHOO UV326, UVP, UV531) work by absorbing harmful ultraviolet radiation and converting it into harmless heat energy, preventing UV damage to the polymer matrix. Light stabilizers (such as YIHOO LS770, LS119), often HALS-type, work by scavenging free radicals generated during photo-oxidation, interrupting the degradation chain reaction. Both are often used together for maximum protection.
Q
Which types of plastics are compatible with YIHOO UV and light stabilizer products?
A
YIHOO UV absorbers and light stabilizers are compatible with most common engineering plastics, including PP (polypropylene), PE (polyethylene), PVC (polyvinyl chloride), PC (polycarbonate), PU (polyurethane), and many others. Please contact us for specific compatibility recommendations for your application.
Q
Do I need to modify my existing production process to incorporate these additives?
A
No. One of the key advantages of anti-aging additives is that they can be incorporated into your existing production process without any significant changes. They are designed to be easily blended into polymer formulations during standard compounding or processing steps, making them a cost-effective and convenient solution.
Q
What specialized polymer additive series does the company offer?
A
Beyond general plastics additives, the company offers specialized product series for PA polymerization & modification, PU foaming, PVC polymerization & modification, PC additives, TPU elastomer, low VOC automotive trim, textile finishing agents, coating additives, cosmetics additives, API, and other chemical products such as zeolite.
