Additional Information
Neoprene, also known as polychloroprene (CR), is a versatile elastomer known for its exceptional oil and flame resistance. It exhibits good flexibility and weatherability, making it suitable for demanding applications across various industries. Neoprene offers superior resistance to oils, fuels, and many chemicals, outperforming natural rubber in this regard. Additionally, its self-extinguishing properties contribute to its use in applications requiring flame resistance.
Neoprene comes in various grades with differing properties, offering options for specific needs. For instance, chlorosulfonated polyethylene (CSM) is a modified version of neoprene with enhanced heat resistance and chemical resistance. However, neoprene can be more expensive than some other elastomers and susceptible to degradation by sunlight and ozone. To overcome this, manufacturers incorporate specific additives to improve its UV and ozone resistance for outdoor applications.
Temperature range: Standard neoprene typically functions well within -50°C to +80°C. High-temperature grades can withstand higher temperatures.
Processing: Neoprene can be processed through various methods like injection molding and extrusion.
Sustainability: While not readily biodegradable, there are ongoing efforts to develop more sustainable versions of neoprene.
