Light Stabilizer Solutions: Protecting Polymers from UV Damage

At Baozhuan New Material, we understand the challenges that polyolefins and TPO systems face under prolonged outdoor exposure. Ultraviolet (UV) radiation can degrade polymers, causing discoloration, loss of mechanical strength, and surface cracking. To address these issues, we developed our advanced light stabilizer, UV-PP4160, engineered to provide outstanding UV protection and extend the service life of polymer products.

Why Light Stabilizers Are Essential

Exposure to sunlight is one of the leading causes of polymer degradation. Over time, UV radiation can break down polymer chains, reducing flexibility, strength, and overall performance. Our light stabilizer is specially designed to prevent UV-induced damage, ensuring that polyolefin and TPO systems maintain their physical properties and appearance even under harsh environmental conditions.

By integrating UV-PP4160 into your formulations, manufacturers can meet polyolefin weathering requirements specified by major automobile OEMs and other high-standard industrial applications.

Applications Across Industries

Our light stabilizer is highly versatile, with proven performance in:

• Automotive components: Exterior trims, bumpers, and dashboard parts requiring long-term UV resistance

• Construction materials: Outdoor panels, piping, and roofing elements exposed to sunlight

• Consumer goods: Garden furniture, playground equipment, and other outdoor polyolefin products

The additive’s excellent compatibility with polyolefins ensures uniform dispersion and prevents blooming, maintaining a smooth surface finish and aesthetic quality.

Technological Advantages of UV-PP4160

UV-PP4160 leverages advanced dispersion technology and high-quality PP carrier masterbatch production to deliver consistent performance at low concentrations. Key advantages include:

• Improved UV stability and aging resistance in polyolefin and TPO systems

• No precipitation, no mold scale, low odor, and low VOC emissions

• Very good compatibility with polyolefins, preventing blooming phenomena

• Effective even at low concentrations (0.1–0.5%) for cost-efficient protection

Under SAE J2527 standard conditions, UV-PP4160 demonstrates exceptional resistance to xenon lamp and QUV UV aging tests, maintaining polymer integrity over thousands of hours of exposure.

Optimized Use and Storage

To achieve the best performance, UV-PP4160 should be evenly mixed with plastic particles and then processed through extrusion or injection molding. Recommended dosage ranges from 0.1% to 0.5%, depending on the desired level of UV protection and aging resistance.

Our stabilizer is also designed for long-term storage. When kept in its original sealed packaging, UV-PP4160 remains stable for at least one year, ensuring consistent quality for large-scale production.

Sustainability and Performance Trends

At Baozhuan, we recognize that modern manufacturers demand durable and environmentally responsible additives. UV-PP4160 allows manufacturers to extend product lifespan without increasing material usage, reducing waste and supporting sustainable polymer production.

Moreover, as polymers are increasingly used in outdoor and high-performance applications, the demand for advanced light stabilizers grows. Our research focuses on next-generation UV protection to ensure polymers not only meet current standards but exceed industry expectations, particularly in automotive and construction sectors.
