PVC Modified Polymers ABS and Polyesters

- January 01, 2016 -

Dow™ Elvaloy® PVC modified polymers are highly miscible in PVC, offering opportunities for PVC-based manufacturers to differentiate product performance and increase productivity through compounding efficiency and formulating advances.

Dow™ Elvaloy® modified polymers serve as permanent PVC plasticizers or as impact modifiers and process aids; they address needs for longer PVC product life, improved impact performance, or reduced material or operating costs.

Typical benefits include:

• Performance under conditions in which a liquid plasticizer would migrate, such as outdoor exposure to weather or contact with chemicals
• Increased melt strength for thinner parts, better foam cell structure or wider thermoforming window
• Reduced scrap and higher yields through improved flow and fusion characteristics, which allow for lower processing temperatures and a wider processing window in rigid PVC
• Reduced cost by enabling higher filler levels while meeting impact properties
• Impact strength that meets or exceeds industry standards.

Elvaloy® resins are also used for ABS and polyester toughening. For more information about these applications, refer to:
