Compounders choose Denka™ Neoprene G types for applications where building tack is important in fabricating the final product and when the end-use involves severe flexing or other dynamic stresses, and minimum compression set is not required.
Neoprene G types are used when a compound requires high loadings with a minimum of plasticizer. Because G types break down of soften under shear during mixing, workable viscosities can be achieved.
When to Use W Types
Neoprene W types are chosen where service conditions call for polychloroprene with the best heat aging and compression set resistance. Neoprene W types frequently are used because of their combination of excellent storage stability, uniform processability, broad compounding latitude, and all-around good vulcanizate properties.
When to Use T Types
Neoprene T types typically are used in calendaring and extrusion applications. They frequently are used in the production of extruded profiles requiring low die swell, little distortion, and high green strength.
Neoprene is a multipurpose elastomer that has a balanced combination of properties. All types of Neoprene have these inherent characteristics:
- Resist degradation from sun, ozone, and weather,
- Perform well in contact with oils and many chemicals,
- Remain useful over a wide temperature range,
- Display outstanding physical toughness, and
- Are more resistant to burning than exclusively hydrocarbon rubbers.
Neoprene G, W, and T types are available in a number of grades. The table below can be used to evaluate qualitatively physical properties of Neoprene grades, including raw polymer, uncured compound, and vulcanizate properties.
