Neoprene is the commercial name of the company “DuPont” of Chloroprene gum also known as CR. Obtained from the polymerization of chlorine and butadiene, this polymer, introduced in the market in 1931, boasts the primacy of being the first synthetic rubber launched on the large scale market.
For its all-discrete features it is highly versatile, it is the generic gum that can be used in all areas where we are not under severe heat conditions, pressures, or forces applied.
It happens because of its strong compatibility with sea salts that make it very widespread in the marine sector.
If used pure is self-extinguishing. Depending on uses and needs, we propose different qualities of NBR, each designed to meet the different needs of the customer.
- NEOPRENE STANDARD
- NEOPRENE SUPER
- NEOPRENE EXTRA
- Good mechanical strength 20 – 25 MPa
- Good oil resistance at low temperatures and acceptable to tall.
- Good resistance to oxygen and aging.
- Excellent compatibility with sea salts
- Discrete Resistance to acids, bases (better than natural rubber and SBR)
- Flame resistance for the presence of halides (If used pure is self-extinguishing)
- Usage temperatures: -20 ° C to 100 ° C (already at 0 ° C starts to crystallize
- Excellent resistance to seawater with salts, bases and diluted acids
- Good mechanical properties
- Excellent resistance to abrasion, laceration and fatigue.
- Excellent resistance to UV radiation
- High gas impermeability
- Poor compatibility with concentrated acids
- Poor compatibility with aromatic hydrocarbons
- Poor compatibility with chlorinated polar solvents, ketones, esters and ethers, phenols, fluids of the HDF group.
- It is not possible to produce non-toxic items.
- Poor dielectric properties
Mechanical: Generic rubber that can be used in all areas where we are not subject to the heat conditions, pressures, or forces applied. In boating it is very much used for its strong resistance to sea salts. Over time it has been replaced by more powerful tires.
Food: There is no food version.
Electrical: the poor dielectric properties limit it in this field
Chemical: it has discrete compatibility with acids and is therefore often replaced with more powerful gums if the concentrations are high.
