Key Differences
Polyurethane stands out for its exceptional durability and resistance to abrasion, chemicals, and oil, making it ideal for industrial and automotive applications. Its versatility allows it to be tailored into various forms, from rigid foams to elastic coatings. Neoprene, on the other hand, is celebrated for its excellent waterproofing, insulation, and weather-resistant properties. This synthetic rubber is commonly used in wetsuits, gaskets, and hoses, benefiting from its flexibility and moderate resistance to oils and chemicals.
Polyurethane is often preferred for applications requiring high wear resistance and strength, such as in wheels, industrial floors, and varnishes, neoprene finds its niche in environments demanding insulation against temperature and moisture. Neoprene’s ability to maintain flexibility over a wide temperature range makes it suitable for outdoor gear and protective coverings.
Polyurethane's chemical structure provides a broader range of hardness, which can be adjusted from soft and flexible to hard and rigid. This adaptability makes it useful in both soft applications like sponges and hard ones like electronic instrument cases. Neoprene, with its inherent flexibility and cushioning effect, is favored for products requiring a good seal and vibration dampening, such as in automotive door and window seals.
The environmental resistance of polyurethane varies with its formulation, offering options that are highly resistant to UV light and ozone, critical for outdoor applications. Neoprene, inherently resistant to sunlight, ozone, and weathering, is a go-to material for outdoor applications without the need for special additives or treatments.
Neoprene's uniformity and consistency in physical properties across its types make it a reliable choice for standardized products. Polyurethane’s versatility, however, means its properties can be extensively customized, leading to a wider range of potential applications but requiring more precise selection to meet specific needs.

Polyurethane
Polyurethane (often abbreviated PUR and PU) is a polymer composed of organic units joined by carbamate (urethane) links. In contrast to other common polymers such as polyethylene and polystyrene, polyurethane is produced from a wide range of starting materials (monomers) and is therefore a class of polymers, rather than a distinct compound.
Neoprene
Neoprene (also polychloroprene) is a family of synthetic rubbers that are produced by polymerization of chloroprene. Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range.
Polyurethane
A synthetic resin in which the polymer units are linked by urethane groups, used chiefly as constituents of paints, varnishes, adhesives, and foams
