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.
But the performance of the materials will become degradation or loss like yellowing and the decrease of the relative molecular mass, cracking on surface and loss of luster, due to its feature of structure and the physical state, as well as the exposure to heat, light and heat, oxygen, ozone, water, acid, alkali, bacteria and enzymes and other external factors. What's worse, the degradation would appear in the impact strength, tensile strength, elongation and other mechanical properties, which affects the normal use of polymer materials.
Therefore, the anti-aging of polymer materials has become a problem that the polymer industry has to solve. At present, there are many ways to improve the anti-aging performance of polymer materials, among which the more effective way and the common method is to add anti-aging additives, which is widely used because of the low cost and no need to change the existing production process.

❓ Frequently Asked Questions
Q
What are polymer anti-aging additives and why are they important?
Polymer anti-aging additives are chemical compounds added to plastic materials to protect them from degradation caused by UV light, heat, oxygen, ozone, moisture, and other environmental factors. They are important because they significantly extend the service life of polymer products, prevent yellowing, surface cracking, and loss of mechanical properties such as impact strength and tensile strength.
Q
What is the difference between UV absorbers and light stabilizers?
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 substrate. Light stabilizers (such as YIHOO LS770, LS119), also known as HALS (Hindered Amine Light Stabilizers), work by scavenging free radicals generated during photo-oxidation, providing a complementary and often more durable protection mechanism.
Q
Which types of plastics are compatible with your UV absorbers and light stabilizers?
Our UV absorbers and light stabilizers are compatible with most common engineering plastics and polymers, including PP (polypropylene), PE (polyethylene), PVC (polyvinyl chloride), PC (polycarbonate), PU (polyurethane), and many more. Please contact us to confirm compatibility with your specific application requirements.
Q
Do I need to change my existing production process to use these additives?
No. One of the key advantages of using anti-aging additives is that they can be incorporated into existing production processes without requiring significant modifications. This makes them a cost-effective solution for improving the anti-aging performance of polymer materials with minimal disruption to your current manufacturing workflow.
Q
What specific application product series does your company offer beyond general plastics additives?
Beyond general plastics additives, we offer specialized product series for PA polymerization & modification, PU foaming, PVC polymerization & modification, PC applications, TPU elastomer, low VOC automotive trim, textile finishing agents, coating additives, cosmetics additives, API, and other chemical products including zeolite. We are continuously expanding our portfolio to meet diverse industry needs.
Q
Are your products equivalent to well-known brands like TINUVIN and CYASORB?
Yes. Our YIHOO product line is designed as high-quality equivalents to leading industry brands such as TINUVIN (by BASF) and CYASORB (by Cytec/Solvay). For example, YIHOO UV326 corresponds to TINUVIN 326, YIHOO LS770 to TINUVIN 770, and YIHOO UV3638 to CYASORB UV3638. Our products offer comparable performance at competitive pricing. Please feel free to contact us for technical data sheets and samples.
