Thermoplastics are commonly combined today to form various composites and used in three-dimensional fabricators.  All thermoplastics are essentially plastics except they have the unique quality that allows them to be repeatedly softened when heated and hardened when cooled.  Also due to their ties with plastics, thermoplastics are recyclable.  To learn about the actual plastic recycling process, please visit our section Current Recycling Processes – Plastics.  To learn about the recycling process of composites made up by multiple thermoplastics, please visit our section Current Recycling Processes – Composite. This section provides a list of today’s recyclable thermoplastic materials. The following information was extracted from Engineering Fundamentals.

***Thermoplastics, due to their ties with plastics, are recyclable. ***The following are the thermoplastics that are generally combined to generate composite materials that are commonly used in Fabber machines such as FDM, SLS, CNC. Acrylonitrile-Butadiene-Styrene (ABS) ABS is tough, hard, and rigid.  Good chemical resistance and dimensional stability; creep resistance, electroplatable, moderate strength, inexpensive.  It has the tendency to stress crack. • ABS, extrusion grade. • ABS, flame-retardant grades, molding and extrusion . • ABS, ABS / PVC, flame-retardant grades, molding and extrusion . • ABS, ABS / PC, flame-retardant grades, molding and extrusion . • ABS, ABS / Nylon . • ABS, ABS / PC, injection molding and extrusion . • ABS, Injection Molding Grade(IMG), heat resistant . • ABS, IMG, medium impact . • ABS, IMG, high impact . • ABS, IMG, platable . • ABS, transparent, injection molding grade . • ABS, 20% & 30% glass fiber reinforced, IMG . • ABS, 20% & 40% long glass fiber reinforced, IMG . • ABS, 6% & 7% & 10% stainless steel fiber, EMI shielding (conductive) . • ABS, 20% PAN carbon fiber, EMI shielding (conductive) . • ABS, 20% graphite fiber, EMI shielding (conductive) . • ABS, 40% aluminum flake, EMI shielding (conductive) . • ABS, rubber modified, injection molding and extrusion grades. Cellulosic It is a thermoplastic modified natural polymer substance and used in molding and extrusion compounds. • Cellulosic, ethyl cellulose, molding compound and sheet . • Cellulosic, cellulose acetate, sheet . • Cellulosic, cellulose acetate, molding and extrusion compound . • Cellulosic, cellulose acetate butyrate, molding and extrusion compound . • Cellulosic, cellulose acetate propioniate, molding and extrusion compound . • Cellulosic, cellulose nitrate . Liquid Crystal Polymer (LCP) It has excellent strength yet is expensive.  Good high temperature properties, can be used in thin walls (as thin as 0.2 mm).  Parts can withstand vapor phase reflow and autoclaving temperatures of 135 ΊC. High chemical resistance and flame retardancy.  Very low coefficient of thermal expansion. • Liquid Crystal Polymer, 45% glass fiber reinforced, HDT. • Liquid Crystal Polymer, 40% glass fiber reinforced. • Liquid Crystal Polymer, 30% mineral filled. • Liquid Crystal Polymer, glass fiber reinforced, used for SMT. • Liquid Crystal Polymer, unfilled, medium melting point. • Liquid Crystal Polymer, 30% carbon fiber reinforced. • Liquid Crystal Polymer, 50% mineral filled. • Liquid Crystal Polymer, 30% glass fiber reinforced. • Liquid Crystal Polymer, 30% glass fiber reinforced, high HDT. • Liquid Crystal Polymer, unfilled, platable grade. • Liquid Crystal Polymer, PTFE filled. • Liquid Crystal Polymer, 15% glass fiber reinforced. • Liquid Crystal Polymer, glass / mineral filled. Polyacetal (Acetal) It is lubricious, strong, and has good dimensional stability.  Resistance to creep and fatigue, high abrasion and chemical resistance.  It is commonly used in quality toy parts, handles and knobs, and bearing parts • Acetal, homopolymer. • Acetal, copolymer. • Acetal, homopolymer, impact modified. • Acetal, copolymer, impact modified. • Acetal, copolymer, mineral filled. • Acetal, terpolymer, extrusion and blow molding grade. • Acetal, copolymer, 2% silicone, low wear. • Acetal, copolymer, UV stabilized. • Acetal, homopolymer, 20% glass reinforced.
