the cradle-to-gate analysis include a GWP (kg CO2 equivalent) of -0.39 for Santicizer Platinum G-2000
and -0.55 for Santicizer Platinum G-2030. According to Amanda Freshwater, Technical Service Manager Polymer Modifiers at Valtris, the new products can be used as a replacement for general-purpose plasticisers. Both grades are epoxy soyate esters with performance said to be comparable to other non-phthalate general purpose plasticisers. “They offer good processing performance,

Volatility determined as weight decrease (DIN EN ISO 176 Method B, 3 days 120°C) for a formulation comprising 100 phr PVC K70, 50 phr plasticiser, 3 phr ESBO and 2 phr stabiliser. Source: Evonik
excellent low temperature properties, and out- standing heat stability, she says. Formulators can also combine Santicizer Platinum G-2000 or G-2030 with one of Valtris’s Santicizer non-phtha- late plasticisers, to create optimised solutions for their specific processing needs.
