EPDM raw material is used as main raw material for self-adhesive sealing strip of electric cabinet door

Jan 12, 2019

       The self-adhesive sealing strip of electric cabinet door is made of EPDM rubber foaming and compacting with good elasticity and compression resistance, aging resistance, ozone, chemical action, wide use temperature range (-40 ~120 ~C). It contains unique metal fixture and tongue-shaped fastener, and is durable. It plays a key role.

  The skeleton seal strip is extruded by compact rubber, foamed rubber and steel wire/steel sheet. Ethylene propylene trioxide sealing strip (EPDM) - suitable for the special environment of - 40 (-+160 (?) C, has excellent ozone resistance, ultraviolet light resistance, chemical solvent resistance, and various physical and chemical performance indicators far exceed those of the same kind of products.

  It is widely used in the field of box sealing and building sealing. The cold-resistant, heat-resistant, foaming, solid and special properties of different application fields developed and designed by our company can meet the application requirements. Installation method of mosaic wood door sealing strip: because each manufacturer uses saw blade or slotting knife when grooving. Width is not the same, usually 4 mm, 3 mm, 2.5 mm, 2.0 mm several kinds, the use of 3mm is the majority, use in the selection of sealing strips must be good.

  It's better to install the sealing strip directly into the slot which has been opened in advance of the door gear line. It must grow out about 15mm, so as to prevent the tape from shortening. Electrical distribution cabinet waterproof sealing strip is mainly used for filling, sealing and bonding the edge joints of doors and windows, expansion joints of components and holes. It is a kind of polyurethane elastic sealing foam material solidified by moisture. It can be divided into two types: gun type and tube type. The gun type needs special polyurethane foaming gun to use. The tube type is equipped with rubber hose. It is a one-component, moisture-cured, multi-purpose polyurethane foam filled elastic sealing material. Electrical cabinet sealing strip for installation of foam rubber strip is a special polyurethane product which is filled in pressure-resistant aerosol tank with polyurethane prepolymer, foaming agent, catalyst and other components.

  When the material is ejected from the aerosol tank, the foamed polyurethane material expands rapidly and solidified with the moisture in the air or the contact matrix to form a foam. The cured foam foam has many kinds of effects, such as sealing, sealing, sealing, heat insulation and sound absorption. It is a kind of building material with environmental protection, energy saving and convenient use. It can be used for sealing, plugging, filling, sewing, fixing, bonding, thermal insulation and sound insulation. It is especially suitable for sealing, sealing and waterproofing of plastic steel or aluminum alloy doors and windows and walls.
