Ingeo M700 lactide
The Ingeo lactide and biopolymer product line has been extended with the addition of a high-purity, polymer-grade lactide rich in the stereoisomer meso-lactide. Ingeo M700 lactide can be used as an intermediate for copolymers, amorphous oligomers and polymers, grafted substrates, resin additives and modifiers, adhesives, coatings, elastomers, surfactants, thermosets, and solvents. Ingeo M700 is said to be a lower-cost alternative to high-priced racemic lactides and L- and D-lactides for a host of industrial applications. Unlike racemic lactide’s melting point of nearly 130°C, and L- and D-lactide’s melting point of 97°C, Ingeo M700’s melting point is below 60°C, which simplifies processing requirements. In addition, because Ingeo M700 is essentially an anhydrous form of lactic acid, processors will not have to deal with water when using it.

Ingeo 6201D
Ingeo 6201D is a high-viscosity bioresin designed for the production of meltdown nonwovens, which are widely used in wipes and filters. It is made from renewable resources and has a lower carbon footprint than comparable existing petroleum-based products, offering an estimated 30–50% cost savings over conventional fiber-based nonwoven roll goods.
