Dow ELVALOY HP661 terpolymer
Dow ELVALOY HP661 is an ethylene-n-butyl acrylate-carbonyl terpolymer with high polarity and low-temperature toughness. It has good compatibility with PVC and is used as a PVC macromolecular plasticizer to reduce the migration of small molecule plasticizers and improve the long-term anti-aging ability and low-temperature toughness of PVC.
Dow ELVALOY HP661 parameters:
Fabrication Method: Compounding
Product Series: ELVALOY
Comonomers: CO, butyl acrylate
Density (ASTM D792): 0.960 g/cm³
Melting Point (°C/°F): 62 (143.6) (ASTM D3418)
Melt Index (g/10 min @ 190°C/21.6 kg): 12
Product Advantages:
High molecular weight provides migration resistance
Can be used as a plasticizer for PVC
Excellent low-temperature toughness
Hardness around 69A
Applications:
In soft PVC, it can be used as a permanent plasticizer and will not leach or migrate to the surface of the product during use.
In rigid PVC, it can be used as an impact modifier, improving plasticizing properties, widening the processing temperature window, facilitating filler dispersion, and enhancing surface color.
It significantly enhances the low-temperature performance, polarity, and chemical resistance of the blend.
It complies with European regulations for food contact use.
Storage: Store in accordance with good manufacturing practices. Store indoors in a cool, dry environment. Avoid direct sunlight or UV light.
