Spectadur PB30MB Bamboo Fiber Blend

durable bio-compound

injection molding

 general description

Spectadur PB30MB grades are advanced compounds that deliver improved impact properties combined with enhanced strength and stiffness values. The material is UV/AO stabilized.

Standard grades are built on 30 w.-% mechanically extracted (no chemicals used) 2nd/3rd generation biomass that replaces 30% of virgin PP. Plants absorb atmospheric carbon dioxide (CO2) as they grow. Using biomass to create products turn these constitutes into an effective CO2 storage resulting into a more permanent removal of CO2 from the atmosphere.

Spectadur PB30MB can be blended with bamboo fiber (here), coconut fiber, coffee husk,, rice husk, straw, wooden saw powder or with custom biomass like any agricultural waste.

Part wall-thickness shall be greater than 1.75 mm.

All Spectadur grades are delivered in natural color; they can be delivered according to customer color specifications or can be blended with any traditional color masterbatch during part manufacturing.
