BI DIRECTIONAL FILAMENT TAPE

Egret so-called bi directional tape aka cross filament tape is used a lot for refrigerators & packing industries. It is transparent color. Normally is coated with synthetic rubber resin glue. Plus, it has no liner. The base material is BOPP or PET, laminated fiber glass, which is cross weaved. The material has very high tensile strength and low elongation, not stretchable, and hard to tear. Because of this feature, it is suitable for temporarily holding the plastic or metal parts without moving. In the meantime, after you remove the tape, it has no glue residue on the surface. Silicon coating on the back side is easy for you to release.

Features of Bi Directional Filament Tape

Use transparent BOPP as backing, reinforced by strip or mesh glass fiber

 

It is cross filament instead of mono filament

 

Coated with pressure sensitive adhesive

 

Backing material has very good tensile strength

 

Good electrical insulation features

 

Can be removed with no glue residue & no de-lamination

 

Excellent resistance to abrasion, moisture

 

Can easily conform to many irregular surfaces

 

Process of Bi Directional Filament Tape Production

NO.1

First, we will choose 28 mic to 36 mic thickness polyester film or biaxially polypropylene film.

 

NO.2

Second, we reinforce and laminate the cross-weaved strip fiberglass on the plastic film

 

NO.3

Third, we coat silicon on the back side of the plastic film, to ensure its easy release or unwind.

 

NO.4

Forth, we coat with very high bond synthetic rubber resin adhesives.

 

NO.5

Finally, we use our lathe slitting machines to cut the jumbo rolls to different standard or nonstandard width and length of small rolls. The jumbo size is 1020mmx1000m. In the meantime, we can also rewind to small logs.

FSK TAPE

图片
  FSK TAPE FSK tape is short name for foil scrim kraft tape. It is fire resistant, moisture barrier, very popular in thermal insulation industries. It is combination of aluminum foil, brown kraft paper, fiberglass scrims. It can used for wrapping the air ducts and laminating the glass wool or rock wool thermal insulation, duct board joints applications. It is a cheaper solution compared to other reinforced aluminum foil tape . Notably, it attaches well to rigid & flexible air ducts. Also, it is perfect vapor sealing for fiberglass facing joints. In addition, we have 2 way and 3 way directional scrims foil. As a result, it can meet with your variable requirements.   Features of FSK   A luminium T ape 4.8 mil (120 micron) 3 directional foil scrim kraft backing   Coated with aggressive synthetic rubber resin adhesive   Strong adhesion fit for sealing joints/seams of foil/scrim facing   Good at moisture or air penetration resistance   Good aging resist...

PET TAPE

图片
  Egret PET tape uses polyester film as the base material, the back of the base material is coated with release agent, and the front is coated with high viscosity rubber pressure sensitive adhesive. The main colors of products are white and blue. Pet is obtained by transesterification of dimethyl terephthalate with ethylene glycol or esterification of terephthalate with ethylene glycol to synthesize dihydroxyethyl terephthalate, and then polycondensation reaction. PET adhesive tape has good physical and mechanical properties in the temperature tolerance range, and the long-term temperature can reach 120°. Short-term temperature can reach -20°. The PET industrial adhesive tape has the characteristics of fatigue resistance, friction resistance and dimensional stability. Crystalline saturated polyester, milky white or light yellow, highly crystalline polymer, smooth and shiny surface, is a common resin in life.   Types of PET Tape There are 4 main PET tapes, including PET blue ho...

PO HOT MELT ADHESIVE FILM

图片
  The main component of Po hotmelt film  is PO, which is called polyolefin in Chinese. It is known to include polyethylene and polypropylene. Polyethylene is tasteless, non-toxic, has low-temperature resistant, and good chemical resistance. It can be polarized by graft copolymerization with other acids, thus changing the bonding properties. Polypropylene is divided into isotactic polypropylene C, interacted polypropylene, and random polypropylene, and used for hot melt adhesive base material for random polypropylene.   The po film belongs to the medium melting point of hot melt film, melting point is about 110℃. PO hot melt film has high transparency, all models of products under it are relatively good low-temperature resistance, and high-temperature resistance is general.   Features of PO Hot Melt Adhesive Film Material: PO film   PO backing with high tensile strength   By heating & blow molding, formulate adhesive film   Excellent elongation ...
