Neoprene type W is a specific grade of polychloroprene that has been vulcanized using metallic oxides, specifically magnesium oxide (MgO) and zinc oxide (ZnO), instead of sulfur. This formulation was originally developed by DuPont and is now produced by Denka. It is widely recognized for its versatility and is the most commonly used grade of neoprene for various industrial applications, including gaskets, seals, profiles, and extruded components. One of the key attributes of Neoprene type W is its moderate crystallization properties when exposed to low temperatures, making it suitable for environments where temperature fluctuations occur. This characteristic ensures that the material maintains its flexibility and functional integrity even in challenging conditions.
The hardness of Neoprene type W can be adjusted to meet specific application requirements, with achievable Shore A hardness values ranging from 30 to 90. This wide hardness range allows manufacturers to tailor the material properties for various uses, from soft and flexible applications to more rigid and durable components. As a base formulation, Neoprene type W serves as the foundational element for many neoprene compound formulations used in the industrial sector, allowing for further customization with additives to enhance properties such as oil resistance, flame retardance, and UV stability.
In practical applications, Neoprene type W is favored in the automotive, aerospace, and consumer goods industries due to its excellent mechanical properties, chemical resistance, and durability. It can be found in a broad range of products, including automotive seals, insulation materials, and waterproofing membranes. As manufacturers continue to innovate and adapt this material for new applications, Neoprene type W remains a crucial component in the design of reliable and effective industrial solutions.
