Trends in manufacturing such as evolving technology and intensifying competition pose challenges to cost, quality and efficiency. Maintenance cycles may be longer, and efforts to avoid unplanned shutdowns should be made. Meeting demand for cleaner, more sustainable operations worldwide is also crucial. That means lower emissions and reduced waste.
Meeting these big challenges often comes down to the smallest components. Gaskets, linings, seals and other critical parts in manufacturing machinery need to resist the effects of chemicals, corrosion and extreme temperatures. They should also help control permeation, reduce leakage and enhance product purity. 3M can help. A broad range of fluoroplastics, elastomers, technical ceramics and advanced fiber materials can help you keep your plants operating at peak capacity.
3M™ Fluoropolymers and 3M Technical Ceramic Parts can help you eliminate product contamination, especially in chemicals produced using metals. They can help decrease sudden leakages associated with enamel while helping you enhance your plant safety.
