SPRY (also known as 6PPD and N-1,3-dimethylbutyl-N'-phenyl-p-phenylenediamine) is a chemical used in the rubber industry as an antioxidant and antiozonant. It is commonly used to protect rubber from cracking and fading caused by UV radiation, ozone, and other environmental factors.
When exposed to SPRY, rubber can suffer from swelling, cracking, and loss of elasticity. The chemical can also reduce the rubber's temperature resistance, making it more vulnerable to damage from heat. Additionally, SPRY can seep into the rubber, leading to a decrease in the rubber's overall durability.
