Abstract “Plastics solutions for practical problems” gathers some suggestions that could contribute to solve a series of burning issues thanks to thermoplastic resins. To be successful and to save money, weight, and cost, the use of plastics must take into account complete solution systems including the plastic and its formulation, the unique design freedom, the outstanding combination of mechanical performances and collateral properties, the environmental facets, the broad choice of processing methods including 3D printing, and the recycling opportunities. More than 30 cases are examined to help to think according to this innovative way: metal or glass replacement, structural solutions, esthetic parts, long-lasting parts, transparent parts, fire retardant plastics, high-heat or low-temperature polymers, conductive polymers, antifriction polymers, superabsorbent polymers, thermally conductive plastics, magnetic plastics, heavy compounds, super-soft polymers, antimicrobial solutions, antifogging solutions, chemical-resistant plastics, adhesion issues, semimanufactured products, foams, WPC, phthalate-free solutions, restriction of hazardous substance solutions, and low volatile organic compound; 97 tables display numerous examples of properties, performance, additive producers, compounders, etc.
