SK Functional EVA Evatane 28-420
SK Functional EVA Evatane 28-420 (formerly Arkema) is a premium, ultra-viscous ethylene-vinyl acetate (EVA) copolymer engineered for demanding injection molding, high-filler masterbatches, HFFR compounds, sound-damping, and specialty automotive applications. Manufactured via high-pressure radical polymerization, it delivers exceptional load-bearing capability, superior filler compatibility, and reliable mechanical strength for ultra-precise injection molded parts. With 28% vinyl acetate, MFI 420 (400–440), antioxidant stabilization, and strict contaminant control, it ensures batch-to-batch consistency, excellent filler retention, and mechanical reliability—ideal for Indian injection molding and compound manufacturers seeking high-filler, specialty, and performance-driven solutions.
Functional & Technical Features
- Ultra-Viscous Injection Molding: MFI 420 enables extremely low flow, supporting 50%+ filler loading and precise mold control.
- High Filler Compatibility: Excellent interaction with ATH, MDH, talc, mica, and colorants, maintaining mechanical strength even at high filler concentrations.
- Antioxidant Stabilization: Built-in antioxidant package protects against oxidative degradation during high-temperature processing and compounding.
- Mechanical Strength: Delivers 12 MPa tensile strength and 700% elongation at break, ensuring durability for high-filler and specialty molded products.
- Uniformity & Purity: Strict contaminant control and uniform VA/MI content guarantee predictable, consistent performance in every batch.
- Thermal & Low-Temperature Flexibility: Melting point 65°C, Vicat 40°C—ideal for temperature-variable injection molding and specialty applications.
- Processing Versatility: Compatible with standard injection molding and twin-screw extrusion equipment for masterbatch and compound production.
Applications
Evatane 28-420 is the material of choice for:
- Ultra-Viscous Injection Molding: Used in caps, liners, flexible parts, toys, accessories, and custom industrial components where low-flow and high precision are critical.
- HFFR & High-Filler Compounds: Provides a robust matrix for halogen-free flame-retardant (HFFR) cable insulation, sheathing, and high-filler masterbatches (color, additive, functional) with 50%+ mineral loading.
- Sound-Damping & Specialty Automotive: Enables advanced vibration/sound-damping compounds and specialty automotive parts (seals, gaskets, protective components) requiring consistent mechanical properties and filler compatibility.
- Industrial Mechanical Parts: Delivers mechanical reliability and processing control for demanding engineering and industrial applications.
Key Application Benefits:
- Maintains dimensional accuracy and mechanical strength at high filler loads.
- Prevents filler segregation and ensures uniform compound properties.
- Reduces equipment wear via controlled melt flow, improving production efficiency.
