Explore the key distinctions between flexible and rigid engineering plastics, focusing on their mechanical properties, molecular structures, and typical applications across various industries.
Glass fibers and carbon fibers both reinforce plastics by embedding stiff, high-modulus filaments into the polymer matrix, greatly increasing the material's resistance to bending and stretching. Carbon fibers typically yield a much higher stiffness improvement than glass fibers at a given volume fraction, while also being lighter, though glass fibers offer a more cost-effective stiffness boost.
White PTFE balls are commonly used in valves due to their excellent chemical resistance, low friction, high temperature tolerance, and self-lubricating properties, making them ideal for harsh industrial environments.
