Spectabio LB30MB Bamboo Fiber Blend

biopolymer compound

injection molding

general description

Spectabio LB30MB is a modified PLA-blend. The grade is significantly enhanced with a blend of natural fibers (bamboo, rice or coffee husk, wheat straw, wood powder or any suitable 2nd/3rd generation biomass). Spectabio LB30MB is suitable for a post-process annealing.

Spectabio LB30MB is compostable/biodegradable (microbial and enzymatic degradation) in the targeted disposal environment; the grade is designed to be biodegradable in controlled (e.g. industrial compost facilities). Spectabio LB grades offer a significant reduction in carbon footprint compared to traditional fossil-based plastics.

The grades exhibit good strength and stiffness properties as well as a medium flow combined with improved elongation values. An increased rate of crystallization allows an annealing to a heat-stable temperature of up to 80 °C (HDT-B).

Part wall-thickness shall be greater than 2.5 mm.
