KET-410A
BENQI
white granule
Epoxy functional group chain extender compound
| Quantity: | |
|---|---|
KET-410A is a high-performance, epoxy-functional chain extension agent specifically engineered for the supercritical foaming of PET, PETG, and their recycled counterparts. It is designed to overcome the inherent challenges of processing PET into foam, such as low melt strength and poor viscoelasticity. By effectively extending polymer chains, KET-410A creates the ideal rheological properties for producing uniform, closed-cell microcellular foams using environmentally friendly physical foaming agents like Nitrogen (N₂), Carbon Dioxide (CO₂), and alkane gases.
This advanced additive is your key to manufacturing next-generation, sustainable, and high-value foam products that are lighter, stronger, and more efficient.
Key Features & Advantages
Dramatically Enhanced Melt Strength: Significantly increases the viscosity and elasticity of the PET melt, preventing cell collapse and ensuring the formation of a consistent, fine-celled foam structure during the supercritical foaming process.
Superior Foam Mechanical Properties: Empowers your final foam products with exceptional rigidity, compressive strength, and dimensional stability, outperforming standard foams.
Extended Production Efficiency: Our formula helps prevent mold scaling and deposit buildup. This results in fewer production stoppages for cleaning, a longer continuous production cycle, reduced downtime, and lower operational costs.
Excellent Compatibility: Works seamlessly with virgin PET, PETG, and, crucially, with post-consumer and post-industrial recycled materials (rPET, rPETG), supporting your sustainability goals without compromising performance.
Optimized for Physical Foaming Agents: Perfectly suited for modern, eco-friendly supercritical foaming technologies utilizing N₂ and CO₂, enabling the production of non-toxic, high-purity foams.
Application Fields
KET-410A opens doors to innovation across a wide range of industries
Transportation & Automotive: Ideal for manufacturing lightweight interior parts like door panels, headliners, parcel shelves, and seat bases. Reduces vehicle weight for improved fuel efficiency and lower emissions.
Sustainable Packaging: Creates superior cushioning and insulating packaging solutions. Used for protective foam inserts, lightweight insulated containers for food delivery, and sustainable alternatives to EPS (expanded polystyrene).
Sports & Leisure: The key to producing high-performance, lightweight shoe midsoles (similar to "boost" technology), sports helmets, yoga mats, and floating boards for water sports.
Building & Construction: Serves as an excellent core material for sandwich panels, providing superior thermal insulation for walls and roofs, and as lightweight, rigid boards for various applications.
Industrial Applications: Used for buoyancy modules in marine and offshore industries, as well as for acoustic insulation panels due to its sound-dampening properties.
