   Your choices are...         
   Composite Material       Composite material is filled with a strengthening phase, reinforcement fibers, toughening phase, or other specialty fillers that provide unique properties. 
   Elastomer / Rubber       Elastomers and rubber materials are characterized by their high degree of flexibility and elasticity (high reversible elongation). They are based on a variety of different systems, including silicone, polyurethane, chloroprene, butyl, polybutadiene, neoprene, natural rubber or isoprene, and other synthetic rubber or compounds. 
   Thermoplastic       Thermoplastics can be repeatedly softened by heat and then hardened or set by cooling, which allows parts to be injection molded or thermoformed and scrap to be reprocessed. 
   Thermoset       Thermoset plastics and thermoset resins are cross-linked polymeric resins that are cured using heat or heat and pressure. Cured thermoset resins generally have higher resistance to heat than thermoplastics, but melting cannot reprocess them.

Material System
   Chemical / Polymer System Type       
   Your choices are...         
   Acetal       Acetal is a polyacetal or polyoxymethylene (POM) that provides higher strength than polyethylene-type polymers. Polyacetal materials are susceptible to oxidation at elevated temperatures. DuPont’s Delrin® is a common polyacetal engineering resin that is also used to mold plastic parts. 
   Acrylic       Acrylic polymers are formed by polymerizing acrylic acids through a reaction with a suitable catalyst. Acrylics are known for excellent environmental resistance and fast setting times compared to other resin systems. 
   Butyl / Polyisobutylene       Elastomeric materials are based upon or use a butyl, polybutene, or polyisobutylene chemical system. Chlorinated isobutylene or chlorobutyl can be used alone or in blends with other polymers to achieve special properties.  Butyl is a common term used for the isobutylene isoprene elastomer. It provides resistance to water, steam, alkalis, and oxygenated solvents. Butyl has low gas permeation and is capable of providing high-energy absorption (dampening) and good hot tear strength. The suggested operating temperature for butyl is -75° to 250° F. 
   Epoxy       Epoxy resins exhibit high strength and low shrinkage during curing. Epoxies are used for their toughness and resistance to chemical and environmental damage. Most epoxies are two-part resins cured at room temperature. Some thermally-cured or thermoset one-part epoxies are also available. Depending on the formulation, epoxy resins are used as casting resins, potting agents, resin binders, or laminating resins in fiberglass or composite construction. They are also used to encapsulate electrical conductors in microelectronic packaging, and adhesives in structural bonding applications. 
   Ethylene Copolymer       Ethylene copolymers include (poly)ethylene acrylate acid (EAA), (poly)ethylene methyl acrylate (EMAC), (poly)ethylene ethyl acrylate (EEA), (poly)ethylene vinyl acetate (EVA), (poly)ethylene butyl acrylate (EBAC), (poly)ethylene vinyl acetate (EVA or EVAC), (poly)ethylene vinyl alcohol (EVAL or EVOH), and (poly)ethylene propylene terpolymer (EPM). 
   Fluoropolymer (PTFE / PVDF)       Polymers are based on fluoropolymer chemical systems, such as polytetrafluoroethylene (PTFE) or polyvinylidene fluoride (PVDF). Fluoropolymers are used in applications requiring superior chemical resistance. PTFE is used in applications requiring superior chemical resistance or low friction.

   Phenolics (Melamine, Furan)       Phenolic and formaldehyde resins are thermosetting molding compounds and adhesives that have strong bonds and provide good resistance to high temperatures. Phenolic or phenol formaldehyde, urea formaldehyde, furan, and melamine resins fit into this category. Phenolic resin adhesives made from chemicals of the phenol group and formaldehyde are generally the most durable. Phenolic resins are available in liquid, powder, and film form. Special phenolic resins that harden at moderate temperatures when mixed with suitable accelerators are also available. Phenol-formaldehyde, resorcinol-formaldehyde, resol, and novalac resins are types of phenolic resins. Urea resin adhesives are made from urea, formaldehyde, and catalysts or hardeners. Urea formaldehyde resins can harden rapidly at moderate temperatures, but generally do not have the properties of phenolic resins. Melamine resins are made through a reaction of dicyandiamide with formaldehyde. Most of the resins in this group have excellent dielectric properties. Furan formaldehyde (FF) resins are made by the polymerization or poly-condensation of furfural, furfural alcohol, or other compounds containing a furan ring, or by the reaction of these furan compounds with other compounds (not over 50%). Fire-retardant furans are used in hand lay-up, spray-up, and filament winding operations. Furans are commonly used in foundry binders, grinding wheels, refractories, and other high temperature applications. Furan resins and chemicals are also used in fiberglass composites, hybrid resins combined with epoxy or phenolics, and in corrosion-resistant cements. 
   Polyamide / Nylon       Polyamide is a commonly-used system for molding high-strength engineered components. Polyamides are also used to produce strong hot-melt adhesives. Polyamides provide higher strength than polyethylene or other commodity-type polymers.  Nylon is a well-known example of a polyamide engineering resin that is also used to mold plastic parts.
