How OMNISTAB additives redefine PC Material Limits？

Polycarbonate is a colorless, transparent amorphous thermoplastic material whose name derives from its internal carbonate group. PC exhibits outstanding impact resistance, excellent dimensional stability, high temperature resistance, non-toxicity, and superior dielectric properties. It is the most widely used transparent material among the major engineering plastics.

Ø What are the advantages and applied values of PC material?

High strength and elasticity: PC possesses high mechanical strength and elastic modulus, enabling it to provide superior structural support and impact resistance in various applications.

High Transparency: PC exhibits excellent light transmission, making it suitable for manufacturing medical devices, automotive headlights, and architectural sunshades requiring transparent materials.

High Dimensional Stability: PC features low molding shrinkage and good dimensional stability, making it ideal for producing precision parts with stringent dimensional requirements.

Superior Insulation Properties: PC possesses excellent electrical insulation, making it suitable for manufacturing electronic and electrical components. It maintains stable electrical properties in humid and high-temperature environments.

Ø What are the applications of PC material?

Packaging Industry

The high transparency and impact resistance make it an ideal packaging material. It is commonly used to manufacture food storage containers, bottles, etc..

Electrical and Electronic Equipment

The excellent insulation properties make PC suitable for manufacturing electronic and electrical components such as sockets, switches, connectors...

Automotive Industry

The high strength, heat resistance, and impact resistance of PC enable its extensive use in the automotive sector. It is commonly used in manufacturing headlight lenses, windows, dashboards, and other components.

Construction Materials

PC is also suitable for both indoor and outdoor building applications. It is frequently used in producing translucent roofing, architectural sunshades.

Ø How to obtain High-Performance PC Materials?

During production, storage, use, and even transportation, polycarbonate constantly faces challenges from external factors such as heat, light, air, moisture, and mechanical stress. These factors induce complex chemical and physical changes in PC, including oxidation, hydrolysis, degradation, and cross-linking, which subsequently alter its molecular composition and structural state. These changes not only compromise the physical and mechanical properties of polycarbonate but also diminish its utility and aesthetic appeal, accompanied by problems such as yellowing and reduced light transmission.

By adding effective weathering additives, aging and yellowing caused by environmental factors like UV radiation and thermal oxidation can be effectively resisted, enhancing the quality of PC materials and extending its service life.

Below OMNISTAB high-performance weathering additives are specifically suited for high-performance PC materials.
