Abstract
The invention relates to a fluoroelastomer heat-shrinkable tube and a manufacturing method thereof. In order to overcome the defects that a traditional heat-shrinkable tube has poorer performance on resisting temperature, oil and solvents and cannot adapt to high performance requirements on resisting the oil and the solvents in industries of automobiles, high-speed trains, war industry, aerospace and the like, the invention provides the fluoroelastomer heat-shrinkable tube which mainly comprises the materials of a fluoroelastomer, a fluorine resin acid acceptor, a reinforcing agent and a plasticizer. Meanwhile, the invention also provides a method for manufacturing the heat-shrinkable tube by using the materials. The fluoroelastomer heat-shrinkable tube provided by the invention can be applied to the industries of automobiles, high-speed trains, war industry, aerospace and the like which have higher requirements for resisting high and low temperature and the solvents.
