Product introduction :
EPDM tube is a new type of heat shrinkable product made of EPDM and special resin.After heating, the inner diameter of the sleeve is rapidly shrunk to half and the electronic components to be protected are tightly wrapped in the sleeve without being affected by The impact of the external environment.Compared with the ordinary EPDM rubber tube, this product is cross-linked by electron accelerator radiation, the physical and mechanical properties better, higher voltage level resistance to wear good characteristics. Mainly used for electrical insulation, rust-proof solder joints, agricultural and household machinery protection, decoration and lighting and other electronic, automotive, consumer goods.
Product features :
● high temperature rating can be long-term use in the environment of 150 ℃, 180-200 ℃ in the
environment above or short-term or intermittent use
● The product is rubbery, soft and good elasticity, good installation feel
● contraction rate ≥ 50%
● Final temperature ≥120 ° C
● weather, UV, acid and chemical solvents good performance
