Phillips catalyst
The Phillips catalyst is a special material used in the production of polyethylene, a common plastic. It consists mainly of a metal called chromium supported on silica (sand-like material). When exposed to specific conditions—like certain temperatures and pressures—this catalyst helps convert ethylene gas into solid polyethylene. The Phillips catalyst is valued for producing high-density polyethylene with strong, durable properties. Its development revolutionized plastic manufacturing by enabling efficient, large-scale production of a versatile material used in packaging, containers, and pipes.
