Polyurethane
Polyurethane (PUR) – Polyurethanes are a large family of polymers with widely ranging properties and uses all based on the reaction product of an organic isocyanate with compounds containing a hydroxyl group. Polyurethanes may be thermosetting or thermoplastic, rigid and hard or flexible and soft, solid or cellular with great property variances. Principal applications are in coatings, elastomers and oams. Polyurethane has excellent abrasion resistance but high hysteresis. Rigid polyurethane foams have become widely used as insulation materials because of their combination of low heat transfer and good cost effectiveness. Use as insulation and other applications are restricted by an upper temperature capability of about 250°F. Polyurethanes do not survive well in direct sunlight or in contact with most organic solvents. Two types of polyurethane are common: polyester based and polyether based, with these backbone structures actually comprising a significant part of a so-called polyurethane resin.
Polyurethanes (PUR) offer Hydrolysis Resistant, Good Flexibility, Low Viscosity, Good Abrasion Resistance, Medium Hardness, Good Adhesion, Low Temperature Flexibility, Good Toughness, High Hardness

Polysulfone
Polysulfone – A family of sulfur-containing thermoplastics, closely related to polyethersulfone (PES). The structure of the polysulfones is aromatic groups, generally with more than one benzene ring, joined by a sulfone group. Generally, polysulfone is a high cost, rigid, amorphous material with low moisture absorption. Reinforcement improves toughness and further enhances dimensional stability, but turns materials opaque. In addition, polysulfones are characterized by high strength, very high surface-temperature limits, low creep, good electrical characteristics, transparency, self-extinguishing ability, and resistance to greases, many solvents, and chemicals. Polysulfones may be processed by extrusion, injection molding, and blow molding. Polysulfone (PSU), introduced by Union Carbide in 1965, was among the first thermoplastics developed for long term service beyond 300°F. Polysulfone offers High Heat, Resistance, Good Chemical Resistance, Flame Retardant, Good Dimensional Stability, Lubricated, Good Toughness, Hydrolysis Resistant, Acid Resistant, Good Creep Resistance, Good Thermal Stability

TPE’s provide excellent weather resistance, shock absorption, outstanding ozone resistance, can be co-extruded, and are available in a range of durometers from very soft to hard. TPE’s provide simplified processing over thermoset rubber since there is no mixing or vulcanization involved. TPE’s offer lower part cost through lower density and thinner wall sections. TPE’s are colorable and can be recycled.
