Epoxy Resin
Epoxy resin is one of the more common terms you’ll come across when searching for laminated tubes online. This is a durable type of resin that manufacturers add to the outside of each tube. The resin serves as a protective coating that can increase the life of that tube. Some epoxies are waterproof or water resistant. Waterproof means that the epoxy will keep water out of the inside of the tube, but water resistant may mean that constant exposure to water can eventually penetrate the tube. Manufacturers will often let you know what grade epoxy the companies used on the tubes.
Melamine Resin
Laminated tubes manufacturers may use a melamine resin in place of an epoxy resin. Melamine is a type of substance that is similar to plastic. It is so strong that some manufacturers use the material to make plates and dishes that are resistant to shattering and breaking. Laminate tubes coated in a melamine resin are usually more durable and can withstand exposure to some of the harshest chemicals. Knowing more about these resins can help you find laminate tubes that are perfect for your next job.
