Spectabio TR45MB

biopolymer compound

injection molding

 general description

Spectabio TR45MB are biopolymer compounds. Spectabio TR45MB Rice Husk Blend is directly filled with 45 w.-% of mainly rice husk and other biomass. The material can also be filled with bamboo powder, rice or coffee husk, wheat straw, wood powder or any suitable 2nd/3rd generation biomass under Mottainai 5.0.

Spectabio TR45MB is designed to be completely biodegradable & compostable (microbial and enzymatic degradation) in the targeted disposal environment; it is biodegradable both in controlled (e.g. industrial compost factilities) and in non-controlled (e.g., soil, home-compost, landfill) conditions. The grade offers a significant reduction in carbon footprint compared to traditional fossil-based plastics.

The material exhibits good impact and elongation properties.

Part wall-thickness shall be greater than 1.75 mm.
