Biostrength™: a new range of Modifiers for Bioplastics

Biostrength™700 is a melt strength improver for polylactic acid (PLA). Biostrength™700 substantially increases the melt strength and melt elasticity of PLA, while maintaining high optical clarity. Biostrength™700 improves the processing of PLA for extrusion, calendering, blow molding, thermoforming and foam applications, and is completely transparent in PLA at typical usage levels.

Additionally, adding Biostrength™700 melt strength improver to PLA enables converters to use higher levels of recycled PLA with improved retention of the physical properties.

Arkema has specifically developed Biostrength™130 and Biostrength™150 core-shell impact modifiers to increase the sturdiness of PLA. Biostrength™130 is designed for use in translucent applications, while Biostrength™150 is a higher efficiency modifier for use in opaque applications. Biostrength™130 and 150 retain their high impact properties at –20°C.

Arkema’s Biostrength™ product line is designed to increase productivity and improve product performance for the expanding biopolymer marketplace.
