Advanced Natural Fiber Thermoplastics Filler Technologies

WyoComp's polymer fillers have been successfully used in most plastic processes, products and applications.  The range includes extrusion, compression molding and injection molding.  Customer's have the option to purchase the AgriFi™ directly in the raw biomass form or they can elect to have WyoComp compound and pelletize the materials (PolyFi™) based on their specific requirements.  Don't hesitate to contact us to learn more about our advanced natural fiber polymer filler technologies, the performance benefits, cost reductions, green marketing and sustainability benefits including reductions in carbon footprint and more.  We offer 20 years of experience to back our technologies and have a history of success through spearheading new innovation and bringing new technologies to market. 

Natural fibers, whether derived from wood or agricultural biomasses, make ideal fillers for thermoplastics used in extrusion, injection molding and compression molding processes. They are renewable, cost effective, thus lowering manufacturer's production costs, provide physical property benefits and more such as "green" marketing advantages and code compliance.

However, without the proper pretreatments, natural fibers contain moisture, starches, sugars, lignin and other extractives that create "off-gassing" and other issues under high heat and pressure conditions in polymer processes, thus making them infeasible to use in many cases.  AgriFi™ product lines offer solutions to these issues and others with its differing process treatments to agri biomasses which is further supported by our technical assistance.

AgriFi™ Description:
Our thermal mechanical treatment process technologies address all the off-gassing and moisture issues associated with natural fiber polymer fillers by removing the extractives without compromising the integrity of the cellulose and hemicelluose structures of the remaining fibers.  AgriFi™, a hydrophobic fiber, provides a number of physical property benefits to products and lowers costs.  It's less than carbon neutral, half the density of mineral fillers and allows for exact control of properties.   

Production Loading Info:
AgriFi™ technologies can be successfully used as polymer fillers with loading levels as high as 80% by weight depending upon the polymer, process and finished product specs/tolerances.  The polymer filler can be dry mixed, compounded into pellets or directly fed into machines depending upon the process and products being manufactured.
