Polyamide (PA)

Nylon (Polyamide) – The generic name for all long-chain fiber-forming polyamides with recurring amide groups. Polyamides (Nylon) comprise the largest family of engineering plastics with a very wide range of applications. Polyamides (Nylons) are often formed into fibers and are used for monofilaments and yarns. Characteristically polyamides (nylons) are very resistant to wear and abrasion, have good mechanical properties even at elevated temperatures, have low permeability to gases and have good chemical resistance.

Polyamide (Nylon) polymer was first commercially introduced by DuPont as a result of the significant research work of W. H. Carothers in the 1930s, who was conducting early extensive research efforts in polyesters and polyamides. The first important polyamide was Nylon 66 produced by the reaction of adipic acid (a 6-carbon dibasic acid) and hexamethylene diamine (a 6-carbon aliphatic diamine). Several structural modifications with differing temperature capabilities have become commercially available including Nylon 46, 610, 612, 6, 11, etc.

Polycarbonate (PC)

Polycarbonate (PC) – This material is formed by a condensation polymerization resulting in a carbon that is bonded to three oxygens. The most common system for this polymerization is formed by a reaction of bisphenol A and phosgene. Applications of polycarbonate are almost always those which take advantage of its uniquely high impact strength and its exceptional clarity. These unique properties have resulted in applications such as bulletproof windows, break resistant lenses, compact discs, etc. More recently however, additional interest has resulted because of the low flammability of polycarbonate.

Polycarbonates (PC) were first prepared by Einhorn in 1898 and extensively researched until 1930 where they were discarded. Research was then started in the mid 1950s by General Electric and in 1958 the Polycarbonate popularity expanded to a global community. Today, approximately 75% of the Polycarbonate market is held by SABIC Innovative Plastics and Covestro (formerly Bayer MaterialScience).

Polypropylene (PP)

Polypropylene (PP) – This polyolefin is readily formed by polymerizing propylene with suitable catalysts, generally aluminum alkyl and titanium tetrachloride. Polypropylene properties vary according to molecular weight, method of production, and the copolymers involved. Generally polypropylene has demonstrated certain advantages in improved strength, stiffness and higher temperature capability over polyethylene. Polypropylene has been very successfully applied to the forming of fibers due to its good specific strength which is why it is the single largest use of polypropylene. Polypropylene also happens to be one of the lightest plastics available with a density of 0.905 g/cm².

Polypropylene (PP) was discovered in 1954 and grew a strong popularity very quickly. Because of extensive research, five main variations of Polypropylene have emerged as: homopolymers, impact (block) copolymers, random copolymers, rubber modified blends, and specialty copolymers.

Polystyrene (PS)

Polystyrene (PS) – Polystyrene is an amorphous, glassy polymer that is generally rigid and relatively inexpensive. Unfilled polystyrene has a sparkle appearance and is often referred to as crystal PS or general purpose polystyrene (GPPS). High impact polystyrene grades (HIPS) are produced by adding rubber or butadiene copolymer which increases the toughness and impact strength of the polymer. Polystyrenes possess good flow properties at temperatures safely below degradation ranges, and can easily be extruded, injection molded, or compression molded. Considerable quantities of polystyrene are produced in the form of heat-expandable beads containing a suitable blowing agent which ultimately results in familiar foamed polystyrene articles.

Polystyrene (PS) has been known for well over one hundred years but its real molecular nature was not clarified until about 1920 when the work of Staudinger elucidated the materials molecular structure in the very early days of polymer science. About 1930 I.G. Farben, in Germany, first produced polystyrene, while at the same time the Dow Chemical Company commenced their ultimately successful development of the material.

Polyphenylene Ether (PPE)

Polyphenylene Ether (PPE) – A thermoplastic, linear, noncrystalline polyether obtained by the oxidative polycondensation of 2,6-dimethylphenol in the presence of a copper-amine-complex catalyst. Polyphenylene ether, also called polyphenylene oxide, is usually blended with polystyrene to improve its toughness and processability. Polyphenylene ether has excellent electrical properties, unusual resistance to acids and bases, and is processable on conventional extrusion and injection molding equipment. PPE is easily attacked by some hydrocarbons, although it resists many chemicals. Polyphenylene ether possesses excellent dimensional stability, low moisture absorption, and high mechanical and dielectric strength.

In 1965 polyphenylene ether was introduced as polyphenylene oxide (PPO) by the General Electric Co. in the U.S. and by AKU in Holland. Unfortunately for polyphenylene oxide its price is too high to justify extensive use which led to the introduction of the related and cheaper Noryl (PPE+PS) materials by General Electric Co. in 1966.

PVC

Polyvinyl Chloride (PVC) – A polymer made by the catalytic polymerization of vinyl chloride. PVC also includes copolymers that contain at least 50% vinyl chloride. The neat homopolymer is hard, brittle and difficult to process, but it becomes flexible when plasticized. Polyvinyl chloride molding compounds can be extruded, injection molded, compression molded, calendered, and blow molded to form a huge variety of products, either rigid or flexible depending on the amount and type of plasticizers used. There are more compounding recipes for PVC than for any other polymer. Rigid PVC is strong, difficult to burn, has excellent resistance to strong acids and bases, to most other chemicals, and to many organic solvents. Additionally, polyvinyl chloride is one of the least expensive plastics.

Polyvinyl chloride (PVC) was first produced commercially in the USA in 1933 and had an important use as cable insulation during the second World War. Polyvinyl chloride then became used for many more applications soon after.

PEI

Polyether Imide (PEI) – PEI is considered an advanced thermoplastic which has both ether links and imide groups in its polymer chain. Polyether imide has gained rapid acceptance as a high temperature engineering thermoplastic material competitive with the polysulfones, polyphenylene sulfides, and polyketones. Polyether imide exhibits high tensile strength without the use of reinforcement, flame resistance, very low smoke emission, and excellent hydrolytic stability. Because of PEIs high stability, its range of processing is wider than many other thermoplastics.

In 1982 General Electric introduced the first polyetherimide (PEI) under the trade name Ultem. They discovered that the presence of the ether linkages was sufficient to allow the material to be melt processible, while retaining many of the key characteristics of polyimides.

PEEK

PEEK is a semicrystalline thermoplastic with excellent mechanical and chemical resistance properties that are retained to high temperatures. The processing conditions used to mold PEEK can influence the crystallinity and hence the mechanical properties. Its Young’s modulus is 3.6 GPa and its tensile strength is 90 to 100 MPa. PEEK has a glass transition temperature of around 143 °C (289 °F) and melts around 343 °C (662 °F). Some grades have a useful operating temperature of up to 250 °C (482 °F). The thermal conductivity increases nearly linearly with temperature between room temperature and solidus temperature. It is highly resistant to thermal degradation, as well as to attack by both organic and aqueous environments. It is attacked by halogens and strong Brønsted and Lewis acids, as well as some halogenated compounds and aliphatic hydrocarbons at high temperatures. It is soluble in concentrated sulfuric acid at room temperature, although dissolution can take a very long time unless the polymer is in a form with a high surface-area-to-volume ratio, such as a fine powder or thin film. It has high resistance to biodegradation.

Post Consumer & Post Industrial Recycled Items

PCR

Post-consumer recycled content is material made from the plastic items consumers recycle every day. These materials are typically collected by local recycling programs and shipped to recycling facilities to be sorted. These materials are then purchased, repelletized, and molded into new items.

PIR

Post-industrial recycled content (also known as pre-consumer waste), refers to waste generated from the manufacturing process that leads to the creation of the source material. For example, when plastic is processed the scrap left behind can then be utilized as PIR, which can be saved, repelletized, and molded into new items.

FEATURES

PCR and PIR can often provide the same physical property characteristics as virgin resins at 100% or a certain percentage mixed with virgin pellets. In some cases, it can also provide a cost savings based on current market conditions/pricing of virgin pellets.

USES

In most instances, PCR and PIR can be used in the same applications that current virgin resins are being used in. However, applications that have regulatory requirements may be a challenge (i.e., flame retardancy requirements and the need for a UL Flammability Rating, FDA Certification, Medical Regulatory Requirements, etc.).
