Hydex® 4101L is a very stable chemical compound that can withstand high impact without deterioration. Hydex® 4101L uses a proprietary lubricating system that meets or exceeds Delrin AF. Unlike Delrin AF, Hydex® 4101L is approved for direct contact with food by the FDA and is ideal for machined parts in food processing equipment. Hydex® 4101L has excellent resistance to typical cleaning chemicals such as chlorine and caustic solutions and has a very low moisture absorption rate, as much as 15 times less than nylon.
