Silicone Masterbatch: Enhancing Scratch Resistance and Processing Performance in Polyolefins

At Baozhuan New Material, innovation drives everything we do. With decades of experience in polymer additives, our R&D team continuously develops solutions that enhance both the performance and processability of modern plastics. One of our most trusted and widely used solutions is the silicone masterbatch, particularly our flagship grade — BZPP303.

What Makes Our Silicone Masterbatch Unique

Our silicone masterbatch is an organic group-modified ultra-high molecular weight polysiloxane using polypropylene (PP) as a carrier. This unique structure gives it exceptional compatibility with polyolefin systems, resulting in superior dispersion, scratch resistance, and surface finish compared to ordinary silicone-based additives.

With an effective content of 50%, BZPP303 improves melt flow, enhances mold release, and reduces surface defects — all without affecting the appearance or mechanical integrity of the finished part.

In practical terms, this means smoother processing, cleaner molds, and products that retain their gloss and scratch resistance even after prolonged use.

Applications Across Industries

Our silicone masterbatch finds extensive use in automotive, home appliance, and consumer goods industries — where both appearance and durability matter.

In automotive interiors, such as door panels, dashboards, and center consoles, BZPP303 helps maintain a smooth, clean look even after years of contact and wear. The additive forms a micro-smooth surface layer that resists scratches from fingernails, rings, or keys — a common challenge for polypropylene-based components.

For home appliances and daily-use plastics, it enhances scratch resistance and mold release while maintaining low odor and no precipitation, ensuring long-term stability and quality.

Key Advantages of Baozhuan’s BZPP303 Silicone Masterbatch

Our BZPP303 offers a comprehensive set of benefits that extend far beyond surface appearance:

• Excellent scratch resistance with long-lasting effect

• Low odor and no precipitation for cleaner production

• Little to no impact on stress whitening of molded parts

• Improved flow properties, ensuring consistent processing

• Stable performance even after heat treatment

Through internal testing, we’ve observed significant improvements when adding just 2% silicone masterbatch to a PP + EPDM + Talc (T20) formula. The treated material showed far better scratch resistance, smoother finish, and enhanced durability — results that compounders and OEMs immediately recognize in both aesthetic and functional value.

The Science Behind Better Performance

At Baozhuan, we understand that not all silicone-based additives behave the same. Many traditional products tend to migrate to the surface, leading to precipitation, uneven gloss, or loss of performance over time.

Our ultra-high molecular weight silicone ensures the additive remains well-dispersed within the polymer matrix, providing consistent protection throughout the part’s lifetime. The PP carrier resin also ensures easy blending with other polyolefins during compounding, eliminating compatibility issues common with lower-quality products.

Committed to Innovation and Quality

Every additive we develop reflects our philosophy of integrity, innovation, pragmatism, and efficiency. By partnering with top universities like Sichuan University, we ensure our products are backed by scientific validation and real-world performance data.

Our commitment extends beyond performance — we also help manufacturers reduce processing costs, improve production stability, and achieve smoother workflow through customized solutions tailored to their specific polymer systems.
