Is LaTeX a rubber or a plastic?

LaTeX can refer to natural latex which is rubber, not plastic, or LaTeX software which is neither rubber nor plastic. Natural latex from rubber tree Hevea brasiliensis is natural rubber, which is elastomer, a type of rubber, not plastic, though both rubber and plastic are polymers. Natural rubber latex is milky sap containing rubber particles that are vulcanized to make solid rubber products like gloves, balloons, condoms, mattresses, which are elastic and stretchy, characteristic of rubber, not hard plastic. Synthetic latex like styrene butadiene rubber is also rubber, synthetic rubber made from petroleum, used in paints and adhesives, still classified as rubber, not plastic, though it is synthetic polymer. So natural latex is rubber, not plastic. LaTeX typesetting software is document preparation system for academic writing, not a material, so not rubber or plastic. So if you mean latex material, it is rubber, natural rubber, not plastic, though some call synthetic latex a type of plastic emulsion, but technically it is synthetic rubber. Natural latex is elastic rubber, plastic is less elastic and more rigid.
