Benefits of technology

This patented new type of elastomeric composition called CBR (Curable Rubber Composite) uses both synthetic rubbers like NR or PE resin together with special chemical agents such as ammonium salts and alkoxides. These compositions have improved properties compared to existing materials due to their combined use of different types of components. They also maintain better stability over long periods under severe conditions without losing its original quality. Overall these technical improvements make them suitable for various applications where high durability against ozone damage and UV light exposure needs.

Problems solved by technology

The technical problem addressed by this patented technology relates to improving the performance of cable made from synthetic material that has good oxygen barrier properties when exposed to air at high temperatures over time without losing its effectiveness due to ageing issues such as degradation caused by exposure to various substances like water vapor present within an enclosed space containing electronic equipment (such as sensors) inside it's housing).
