Material System
   Chemical / Polymer System Type       
   Your choices are...         
   Fluoroelastomer       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.  
   Isoprene       Natural rubber is based on the polyisoprene or isoprene chemical system. Synthetic or man-made versions of isoprene are also available. 
   PET / PBT       The polyethylene terphthalate (PET) and polybutylene terphthalate (PBT) polymer systems are based on a thermoplastic polyester or terphthalate system. 
   Polybutadiene       Polybutadiene is a commonly-used polymer system with dielectric potting compounds and coatings. It can be combined with other rubber polymers to form flexible sealants. Polybutadiene remains flexible even at low temperatures. 
   Polyether Block Amide (PEBA)       Polyether block amide (PEBA) resins are a type of polyamide with thermoplastic elastomer characteristics. PEBA can be molded to form flexible components such as hydraulic hose, pneumatic tube, boots, and other parts. 
   Polyethylene (PE)       Polymers or resins are based on the polyethylene chemical system. Low density polyethylene polymers are used to form a variety of common or commodity-plastic components. High density (HDPE) and ultra-high molecular weight polyethylene (UHMW PE) have good friction and mechanical properties. They are used in medical devices, wear parts, and engineered components. 
   Polypropylene (PP)       Polypropylene (PP) is commonly used in hot-melt adhesive systems. PP is a polymer based on polypropylene chemical bonds. 
   Polysulphide (PPS)       Polymer resins or compounds are based on polysulfide or polyphenylene sulfide (PPS) chemical systems.  
   Polyurethane (PU)       Polyurethane (PUR) resins provide excellent flexibility, impact resistance, and durability. Polyurethanes are formed through the reaction of an isocyanate component with polyols or other active hydroxyl group compounds. Polyurethanes require a catalyst, heat, or air evaporation to initiate and complete curing.  
   Silicone       Plastic compounds, elastomer resins, or polymers are based on the silicone chemical system. Silicones are produced through the hydrolysis and polymerization of silanes and siloxanes. 
   Vinyl       Polymers are based on the vinyl chemical system. Examples include polyvinyl chloride (PVC), polyvinylidene chloride (PVDF), polyvinyl vinyl acetate (PVA), and polyvinyl alcohol (PVOH).  
   Specialty / Other       Other specialty, proprietary or unlisted resins, chemical systems or compounds or polymer types. 
   Acrylic       Acrylic polymers are formed by polymerizing acrylic acids through a reaction with a suitable catalyst. Acrylics provide excellent environmental resistance and have faster-setting times than other resin systems. 
   Butyl Rubber       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 commonly-used term for the isobutylene isoprene elastomer. It is known for its 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. Butyl's suggested operating temperature is -75° to 250° F.
