There is a wide range of plastic materials used in industrial manufacturing these days. At American Micro Industries, we take great pride in our ability to work with the most popular types of plastics to meet the demands of our customers in industries such as aerospace, automotive, medical and electronics. We’re your best source for expertly machined plastic components that meet your exact specifications.
Whether your material of choice is acetal, acrylics, PVDF, Teflon® or just about any other plastic type, you can count on getting a high-quality product that will exceed your expectations.

Acetal (POM)

Acetal is a polyoxymethylene (POM) compound resin. Delrin® is a noted trade name for this material. Delrin® is a crystalline engineering thermoplastic material that is often used in high-load mechanical applications such as safety restraints, gears, conveyor belts and various types of healthcare delivery systems. Acetal is a light weight, low friction and wear resistant plastic capable of withstanding working temperatures of 200°F (90°C). Delrin® is resistant to liquids, self lubricating and has low coefficient of friction characteristics that makes it well suited for bushing and bearing replacements, particularly in corrosive environments. Delrin® is also FDA approved for use in the food industry. Delrin® machining provides an effective means of manufacturing custom acetal products.

Acrylics (PMMA)

Acrylics glass is a polymethyl methacrylate (PMMA) synthetic polymer. This thermoplastic is commonly known as Plexiglas® and Lucite®. It has a high impact strength and will not shatter; but is more susceptible to cracking than polycarbonate. Acrylics are softer and more easily scratched than glass . Acrylics have a higher transmittability of visible light than glass; however UV light is not blocked or filter unlike glass. It allows infrared (IR) light up to 2,800 n-m wavelength to pass freely and essentially blocks IR up to 25,000 n-m. While producing machined acrylics is possible, machining does present several challenges. For example, the abrasive nature of the glass filler can cause the cutting tools to wear out faster. Also, the material is more susceptible to delamination while machining.

Noryl® (PPO)

Noryl® is a modified polyphenylene oxide (PPO) resin. Noryl® combines the benefits of an amorphous PPO resin with valuable attributes, such as superior dimensional stability, low specific gravity and the ability to be processed with ease. It also provides good creep resistance, even at elevated temperatures. This resin has great mechanical stability, impact resistance, high strength, thermal stability properties and low water absorption rates. However, it has poor chemical resistance and color stability. Noryl® is capable of withstanding working temperatures of 220°F (104°C).

PVC

PVC is a thermoplastic polyvinyl chloride (PVC) polymer. PVC is a rigid polymer with excellent resistance to strong acids and alkyds. It has a working temperature of 176°F (80°C). PVC has a good fire resistance rating; it is difficult to ignite and is typically self extinguishing. PVC-300®, VINTEC I® & NELS-TEK 600® are noted trade names.

CPVC is a thermoplastic produced by chlorination of polyvinyl chloride (PVC) polymer. CPVC shares most of the properties of traditional PVC with some enhancements. It can withstand higher temperatures of corrosive water than PVC. CPVC has a working temperature of 200°F (90°C). It is more ductile than PVC, thus exhibiting greater flexural and crush strength. It has similar fire resistance to that of PVC.

PVDF

PVDF is a polyvinylidene fluoride polymer. Kynar® & Solef® are noted trade names for this material. It is strong and tough as reflected by its tensile properties and impact strength. It is resistant to creep under mechanical loading. It is stable when exposed to UV and sun light. PVDF has high abrasion resistance, thermal stability and high dielectric properties. PVDF is especially well-suited for applications requiring high purity and superior resistance to acids, bases and solvents. PVDF can be used as insulation for electrical wiring because of its flexibility, light weight, low thermal conductivity and excellent corrosion and heat resistance. PVDF machining is also achievable.

Polycarbonate (PC)

Polycarbonate is a group of thermoplastic polyesters. Lexan® & Mackrolon® are noted trade names for this material. It has a high temperature resistance, outstanding impact resistance and outstanding optical properties that make this resin so unique. However, it is susceptible to degradation effects of ultraviolet (UV) light. Lexan® has a working temperature range of -211° to 239°F (-135° to 115°C). Polycarbonate has numerous industrial applications. Its strong insulation capabilities and inherent safety features makes it suitable for use in electrical components. The automotive and aerospace industries use polycarbonate plastic for the sputter and evaporation deposition of aluminum.

Polypropylene (PP)

Polypropylene (PP) is a thermoplastic polymer. It is readily resistant to chemical solvents, acids and alkyds. Polypropylene has very good fatigue resistance. Thin sheets are used as dielectric insulators within certain high performance pulse and low loss RF capacitors. It is used in medical products due to its ability to withstand the heat of autoclaving.
A more recent polypropylene application is its use as building construction material. Various types of custom parts and components can be produced via polypropylene machining.

Teflon® (PTFE)

Teflon® is perhaps the most widely recognized plastic material. Accidentally discovered by a DuPont chemist nearly 80 years ago, Teflon® was originally used as a protective coating for pipe valves and seals.
Teflon® is a polytetrafluroethylene (PTFE) synthetic flouropolymer. It has a working temperature limit of 460°F (237°C). Teflon® has the lowest coefficient of friction of any solid material known. It is commonly used in bushing and bearing applications. Teflon® has excellent dielectric properties, especially at high radio frequencies. It is subject to creep, also known as "cold flow" and "compression set", which can compromise seal integrity. Available in Food grade and Virgin Electrical grade.

UHMW (UHMWPE)

UHMW is a ultra high molecular weight polyethylene (UHMWPE) thermoplastic. It is a very tough material with the highest impact strength of any thermoplastic. It is highly resistant to corrosive chemicals, except for oxidizing acids. UHMW has extremely low moisture absorption, very low coefficient of friction and is self lubricating. It is comparable to the properties of Teflon®, except it is more abrasion resistant.
UHMW manufacturing applications include the production of hydraulic seals and bearings. It also serves as a biomaterial used in knee, hip and spine implant devices by the medical industry.
