The Top 10 Plastic Injection Molding Materials
1. Acrylic (PMMA)
Acrylic is a strong, clear thermoplastic that provides a lightweight, shatter-resistant alternative to glass. This injection-molded material also offers excellent optical clarity so that a high percentage of light passes through. Acrylic resists ultraviolet (UV) light and weather, and is also known as PMMA, or by its full chemical name: poly (methyl methacrylate).
Properties
Unlike some plastics, acrylic can withstand exposure to water and hold tight tolerances. PMMA won’t absorb odors, but it cannot resist solvents and is easily stained by greases and oils. Although injection-molded acrylic has high tensile strength, it’s prone to stress cracking under heavy loads.
Applications
Applications for acrylic injection molding include windows, greenhouses, solar panels, bathroom enclosures, and other transparent components for architectural, lighting, and outdoor applications.
Grades and Brands
General-purpose and specialty grades of PMMA plastics are available, including:
Common brand names for acrylic plastics include Trinseo PLEXIGLAS®, which is available with high heat resistance, and DuPont LUCITE®, which has excellent optical clarity and transparency.
2. Acrylonitrile Butadiene Styrene (ABS)
ABS has a relatively low melting point that makes it easy to mold. This opaque polymer supports the use of colorants as well as various textures and surface finishes. Its butadiene content delivers exceptional toughness, even at low temperatures, and its styrene content imparts a shiny, attractive finish to plastic injection molded parts.
Properties
ABS is known for its strength and impact resistance, but it lacks strong resistance to sunlight (UV), water, and weather. Compared to acrylic, injection-molded ABS is not a good choice for outdoor applications. ABS also generates significant smoke when burned and, unlike nylon, provides poor resistance to high friction.
Applications
ABS injection molding is used to produce many types of plastic parts, including:
Grades and Brands
Well-known brands of ABS include Samsung Starex, Toray Toyolac, BASF Terluran, and Ineos Lustran.
3. Nylon Polyamide (PA)
Nylon is a synthetic polyamide (PA) that combines toughness and high heat resistance with high abrasion resistance, good fatigue resistance, and noise-dampening properties. Nylon isn’t inherently flame-resistant, but flame-retardant versions are available. Similarly, although nylon can be degraded by sunlight, a UV stabilizer can be added to improve outdoor performance.
Properties
Compared to other plastics, nylon provides poor resistance to strong acids and bases. Nylon is not as strong as polypropylene and can’t match polycarbonate for impact resistance. Injection molding nylon is challenging because it’s prone to shrinkage and is subject to inadequate mold filling.
Applications
Applications for nylon injection molding include:
With its low coefficient of friction, nylon is also well-suited for applications with high-friction and wear.
Grades and Brands
Nylon comes in four main grades, and each has slightly different mechanical properties:
4. Polycarbonate (PC)
Polycarbonate is strong, lightweight, and naturally transparent. This plastic injection molding material has excellent optical properties to support light transmission, but maintains its color and retains its strength when pigmented. Although it isn’t scratch-resistant, polycarbonate is significantly stronger than glass and is extremely durable.
Properties
Injection-molded polycarbonate is sometimes used instead of acrylic because PC maintains its physical properties over a wider temperature range. PC requires high processing temperatures, however, which can make it more expensive to mold. With its predictable and uniform shrinkage, however, polycarbonate offers precise dimensional control for tighter tolerances.
Applications
Applications for polycarbonate injection molding include:
Because it contains the chemical bisphenol A (BPA), polycarbonate is not recommended for food preparation or storage.
Grades and Brands
Polycarbonate plastic can be filled with glass and is available in grades that contain a relatively small percentage of stainless steel fiber. Popular brands include SABIC Lexan®, which is available in flame-resistant versions, and Covestro Makrolon®, which has glass-like transparency.
5. Polyethylene (PE)
Polyethylene is the most commonly used plastic in the world and is a commercial polymer that can be selected according to its density. High-density polyethylene (HDPE) and low-density polyethylene (LDPE) both provide chemical resistance, but they differ in terms of their hardness, flexibility, melting point, and optical transparency.
Properties
PE plastics include polyethylene terephthalate (PET, PETE), a material that is not defined by its density. Like LDPE, PET can be as clear as glass; however, designers can also select grades of PET or PETE with different levels of optical clarity. HDPE, LDPE, and PET all resist moisture and chemicals, but LDPE is softer and more flexible than HDPE, which is an opaque material.
Applications
Applications for polyethylene injection molding may be limited to indoor applications because of their poor UV resistance. Because they are unable to withstand high service temperatures, these plastic materials may not be suitable for some processing applications. Often, injection molded polyethylene is used in products such as housewares, toys, food containers, and automotive parts.
Grades and Brands
PE plastics come in numbered grades where higher numbers generally indicate higher densities. For example, HDPE 500 has a higher density than HDPE 300. Both grades have a higher density than LDPE, which also uses a numbering system for grades. BASF and DuPont are two of the leading suppliers of PE for engineering (as opposed to general-purpose) applications.
6 . Polyoxymethylene (POM)
Polyoxymethylene (POM) is an engineering plastic that is also known as acetal. It combines excellent rigidity with thermal stability and has a low coefficient of friction. This plastic material has low water absorption and good chemical resistance. In terms of appearance, POM plastics are naturally opaque and white in color.
Properties
In its pure form, acetals have low impact strength and a very high rate of thermal expansion. Yet, POM can be reinforced with fiberglass or minerals for improved strength and stiffness. Compounds that are reinforced with both provide an excellent balance of mechanical properties. Because injected molded POM lacks resistance to sunlight, its outdoor applications are limited.
Applications
With its low coefficient of friction, injection-molded POM is used in bearings, gears, conveyor belts, and pulley wheels. Additional applications include fasteners, eyeglass frames, parts for knives and firearms, lock systems, and high-performance engineering components.
Grades and Brands
There are two main types of acetal plastics: homopolymers, which provide higher hardness and tensile strength, and POM copolymers. Neither type of material can be fire-rated to a standard such as UL 94, and both experience relatively high shrinkage during injection molding. Popular brand names for POM plastics include DuPont Delrin® and Ensinger TECAFORM®.
7 .Polypropylene (PP)
Polypropylene is the second most commonly used plastic in the world. It provides good chemical resistance, retains its shape after torsion or bending, has a high melting point, and won’t degrade when exposed to moisture or water. Injected molded polypro, as PP is sometimes called, is also recyclable.
Properties
Despite its comparative advantages, polypropylene degrades with UV light and is extremely flammable. At temperatures above 100° C (212° F), this injection-molded plastic dissolves into aromatic hydrocarbons, such as benzene and toluene, which are harmful to humans. Polypropylene plastic is also difficult to bond and paint.
Applications
Applications for polypropylene injection molding include
Grades and Brands
Pure polypropylene is a commodity plastic with the lowest density, but high crystalline polypropylene (HcPP) is filled with glass fibers for rigidity. Semitron® from Mitsubishi Chemical Advanced Materials is a leading brand.
8 . Polystyrene (PS)
Polystyrene plastics are lightweight, relatively inexpensive, and resistant to moisture and bacterial growth. These commodity plastics also provide good chemical resistance to diluted acids and bases and have excellent resistance to gamma radiation, which is used to sterilize medical devices.
Properties
There are two main types of polystyrene: general-purpose polystyrene (GPPS) and high-impact polystyrene (HIPS). GPPS is brittle and has less dimensional stability than HIPS, which is compounded with butadiene rubber to enhance its material properties. GPPS also has a glass-like clarity whereas HIPS is opaque.
Applications
Applications for polystyrene injection molding include medical, optical, electrical, and electronic applications. With its higher impact strength, HIPS is often used with appliances and equipment, while injection-molded GPPS is used in plastic toys, cases, containers, and trays.
