Chain Extender is a high-performance polymer additive designed to improve molecular weight, mechanical strength, and processability in thermoplastics. It enhances durability, melt strength, and compatibility, making it ideal for recycled plastics, biodegradable polymers, and industrial applications.
Product Overview
Chain Extender is an additive specifically designed for biodegradable materials, which effectively increases the molecular chain length, thereby enhancing the material's tensile strength. As both a chain extender and nucleating agent, it accelerates the cooling and molding process of materials while improving the viscosity of polyester-based materials. This results in significantly increased tensile strength and puncture resistance for films and sheets. The use of the chain extender improves the mechanical performance and extends the service life of the product.
Key Features
- Enhanced Mechanical Performance: Increases molecular chain length, improving tensile strength and puncture resistance.
- Accelerates Molding Process: Speeds up cooling, reducing production cycle time.
- Increases Viscosity: Enhances the viscosity of polyester materials, improving processing performance.
Applications
- Biodegradable Polyester Materials: Used for chain extension and nucleation in polyester-based materials.
- Films and Sheets: Increases the tensile strength of films and sheets, suitable for packaging materials.
- Plastic Molding: Accelerates molding speed, improving the performance and quality of plastic products.
