Acetal - Chemical Name: PolyOxyMethylene (POM) - also known as Polyacetal and polyformaldehyde. This is used in parts that require good lubricity, wear resistance, dimensional stability, and high stiffness. It is produced as a Homopolymer or as a Copolymer. Wikipedia Link

Acrylic - Chemical Name: PolyMethylMethAcrylate (PMMA). This can be a Thermoplastic or a Thermoset resin. Acrylics have good clarity and stiffness, but can be brittle. They can be impact modified by adding rubber compounds. Impact modified parts, when bent, will turn white or "ghost" at the bending point. Wikipedia Link

Cellulosic Ester Resins - Chemical Names: Cellulose Acetate (CA), Cellulose Triacetate (CA), Cellulose Acetate Butyrate (CAB), Cellulose Acetate Priopionate (CAP). are produced from cellulose fibers derived from plant sources. They start clear and can be colored. These can be resins that are moldable on their own. They can also be formulated as modifiers and additives to impart properties into compounded resins. Typical uses are as binders and film formers in paints, inks, and other coloring and coating applications. Wikipedia Link

Elastomers are a family of flexible resins generically known as ThermoPlastic Elastomers (TPE), ThermoPlastic Rubbers (TPR), and ThermoPlastic Vulcanizates (TPV). There are many specific types and names of rubbers that have varying chemical makeups and functionality. Vulcanizates can be cured by different processes and have good strength and durability, but cannot be melted and molded again. TPE/TPR resins can be recycled, melted, and made into new products.

Fluoropolymers are a broad category of resins that all involve the element Fluorine being bonded to Carbon. These resins are highly resistant to attack from both acids and bases. They also display low coefficients of friction. Fluoropolymers are formulated as homopolymers or copolymers and can be thermoplastics or thermosets. Wikipedia Link

Liquid Crystal Polymers (LCP) are a class of resins that display crystalline properties in their liquid or melt phase. They can also be cross-linked, leading to sub-classes like Liquid Crystal Elastomers (LCE) and Liquid Crystal Networks (LCN). LCPs are unreactive, have good flexibility and perform well in high speed molding. Wikipedia Link

PolyAmides (PA) are a large group of resins that include three sub-classes. The primary sub-class is Nylon (an aliphatic polyamide) in varieties such as Nylon 6 (NY6 or PA6), Nylon 6/6 (NY66 or PA66), Nylon 6/10 (NY610 or PA610) and others. A second sub-class is PolyPhthalAmides (PPA) which are semi-aromatic aramides. Fully aromatic amides are a third subclass which can cross over into being Liquid Crystal Polymers. Wikipedia Link

A class of resins that can include PolyARylAmide (PARA) resins, Polyarylates, as well as PolyArylEtherKetone (PAEK) and other PolyEtherKeton compounds (PEK, PEEK, PEKK, PEEKK, and PEKEKK), which we categorize under PolyEthers. PolyAryls typically have high heat resistance and exhibit excellent properties in other categories, like dimensional stability and strength. Wikipedia Link

PolyButylenes (PB) are mainly used in piping. A sub-class, PolyButyleneTerephthalate (PBT) is common in injection molding. PBT is semi-crystalline and a type of polyester. PBT is often used in electronics, but can be applied in other applications as well. Wikipedia Links: Polybutylene and Polybutylene Terephthalate

Polycarbonates (PC) are thermoplastics formed with carbonate groups as a main component. They are strong, impact resistant plastics that can be optically clear. Certain varieties are useful in medical arenas involving radiation. PCs are versatile materials that find many uses. Wikipedia Link

Polyesters is a family of polymers which consist of ester groups at their core. The most common version is PolyEthylene Terephthalate (PET) which is used in water bottles, food packaging, and textiles among other applications. Wikipedia Link

Polyether resins use an ether compound (as opposed to an ester) as a base component. These can include resins from the Polyaryl class such as PolyEtherKetone (PEK), PolyEtherEtherKetone (PEEK), and other ether/ketone variants, which we include here. Wikipedia Link

Polyethylenes are typically a Commodity Resin, but there are variants that are classified as Engineering Resins. Example is Cyclic Olefin Polymers (COP) and Cyclic Olefin Copolymers (COC). These are amorphous materials that have high clarity and low post-molding shrink rates. Wikipedia Link

Polyphenylenes are a family of resins that exhibit good flame resistance. The main classes are PolyPhenylene Sufide (PPS), PolyPhenyleneSulfone (PPSU) [though this is typically classified as a polysufone] and PolyPhenylene Ether (PPO) [the "O" is for Olefin which covers a broader array of chemicals]. They are used in high performance and high tolerance applications. Wikipedia Links: Poly(P-Phenylene) and Polyphenylene Sulfide

Polysulfones are divided into three main sub-classes: Polysulfone (PSU), PolyEtherSulfone (PES or PESU), and PolyPhenyleneSulfone (PPSU). These are all high performance plastics that can resist heat, often used in electrical applications. Wikipedia Link

Polyurethanes (PU) or Thermoplastic Polyurethanes (TPU) can be rigid or flexible, very hard or quite soft. They exhibit good stiffness and abrasion resistance, often being used as bushing or coatings for casters and wheels. Rigid urethanes can also exhibit good clarity. Wikipedia Link

Polyvinyl resins are family of resins based upon the vinyl monomer. The Polyvinyl class has one main sub-class: Polyvinyl Chloride (PVC) which can be rigid (PVC-R) or flexible (PVC-F). PVC can be opaque or clear. It is inherently flame retardant. Both PVC-R and PVC-F are included in this inventory. Polyvinyl Acetate (PVA or PVAc) is a second sub-class which is wood glue or white glue and not a moldable compound [This is not in our inventory]. The polyvinyl monomer is the underpinning of many plastics including polyethylene, polypropylene, and styrene, which are classified separately here. Wikipedia Link

Styrenics are all based upon the styrene compound, which is part of several resin classes. High Impact Polystyrene (HIPS or STY-HI) is opaque and has good stiffness. General Purpose Polystyrene (GPPS or STY-GP) is very clear and can be referred to as crystal styrene. Butadiene rubber, Acrylonitrile, and Acrylate can be added to create resins such as: Acryolnitrile Butadiene Styrene (ABS), a common industrial/commercial material with good impact resistance; Acrylonitrile Styrene Acrylate (ASA); Styrene AcryloNitrile (SAN), Styrene Butadiene Styrene (SBS) rubber; and others.

This is a grouping of various products that don't have a good category to fit in. This could include sheet scrap and plastic materials that have non-molding uses.

This is a variant of Polypropylenes that is mostly Thermoplastic Polyolefins (TPO) which involve adding a rubber for flexibility and impact resistance. Wikipedia Link
