Each of these monomers imparts specific properties and provides ABS terpolymer with a robust combination of features. ABS offers high strength, toughness, and resistance to impact and temperature. It is easily molded and gives a high-quality glossy surface finish. This plastic polymer does not have a specific melting point.#2 Polycarbonate (PC)A polycarbonate is a group of thermoplastic polymers containing carbonate groups in their chemical structures. Polycarbonate has a high degree of stiffness and thermal resistance due to its molecular structure and a reasonably high viscosity when processed. Even so, polycarbonates can be molded and thermoformed with great ease, making them a popular choice for a wide range of products.#3 Polyoxymethylene (POM)Polyoxymethylene also known as polyacetal/acetal/polyformaldehyde/Delrin, is an engineering thermoplastic used in precision parts requiring high stiffness, low friction, and excellent dimensional stability. As with many other synthetic polymers, it is produced by different chemical firms with slightly different formulas. POM is characterized by its high strength, hardness, and rigidity to − 40°C.#4 Polypropylene (PP)Polypropylene also known as polypropene, is a thermoplastic polymer used in a wide variety of applications. It is produced via chain-growth polymerization from the monomer propylene. Polypropylene belongs to the group of polyolefins and is partially crystalline and non-polar. PP is inexpensive and easy to access, and due to flexible consistency, PP is widely used for manufacturing storage containers, such as bottles and plastic boxes. Polypropylene has a strong resistance to fatigue and chemical corrosion, making it useful for most types of plastic storage containers, kitchenware, water bottles, and even insulation and piping systems.#5 Nylon Plastic (PA)Nylon plastic (PA) is a synthetic thermoplastic polymer commonly used in injection molding applications. It's a versatile, durable, flexible material often used as a more affordable alternative to other materials like silk, rubber, and latex.#6 Acrylic (PMMA)Acrylics are a group of polymers prepared from acrylate monomers. These plastics are noted for their transparency, resistance to breakage, and elasticity. They are also commonly known as acrylate polymers or polyacrylates. Acrylate polymer is commonly used in cosmetics, such as nail polish, as an adhesive. The most common acrylic plastic is polymethyl methacrylate (PMMA).#7 Polyethylene (PE)Polyethylene thermoplastic materials are generally divided into multiple groups, based on density. These include low-density polyethylene (or LDPE), medium density polyethylene (MDPE), high-density polyethylene (HDPE), and ultra-high molecular weight polyethylene (UHMWPE or UHMW). In general, the higher the density, the higher the tensile and flexural strength, chemical and abrasion resistance, and surface hardness.#8 High Impact Polystyrene (HIPS)This cost-efficient material offers excellent machinability, dimensional stability, impact resistance, and aesthetic properties. It is highly customizable and can be glued, printed, bonded, and decorated with ease.
