To save costs and reduce weight, a company is exploring graphene as a filler for thermoplastic resins. Work to date has shown that graphene dispersion is generally poor in thermoplastics, leading to less than optimal reinforcement properties and darker color. The manufacturer is specifically interested in the reinforcement properties of graphene in polyethylene and polypropylene. Potential solution proposals must include the source of the material, the matrix they are dispersing into, the level of transparency and color, and some measure of mechanical reinforcement.
