HYDEX® 4101 PBT

About
HYDEX® 4101 & 4101L (lubricated) is a very stable chemical compound that can withstand high impact without deterioration. It is approved for direct contact with food by the FDA and is ideal for machined parts in food processing equipment. HYDEX™ 4101 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. HYDEX® 4101 & 4101L (lubricated) exhibits a broad range of outstanding properties for a variety of applications, especially in the food processing industry. It is ideal for applications such as cams, bearings, gears, food pistons, wear strips, scraper blades, valve bodies and conveyor components. Good chemical resistance properties High impact strength A wear factor up to 50% better then PET-P Very low moisture absorption rate Excellent machining qualities No center line porosity&&
