A roll of PSA office tape in a dispenser Adhesive tape refers to any one of a variety of combinations of a backing materials coated with an adhesive. Different backing materials and adhesives can be used depending on the intended use. History Pressure-sensitive adhesive, a key component of some adhesive tapes, was first developed in 1845 by Dr. Horace Day, a surgeon. In 1901, the German Oscar Troplowitz invented an adhesive patch called Leukoplast for the German company Beiersdorf AG.
Types Pressure-sensitive tape Main articles: Pressure-sensitive tape and Chemistry of adhesive tapes Dennison Mending Tape from the second half of the 20th century. From the Museo del Objeto del Objeto collection. Gaffer tape Pressure-sensitive tape, PSA tape, self-stick tape or sticky tape consists of a pressure-sensitive adhesive coated onto a backing material such as paper, plastic film, cloth, or metal foil.
It is sticky (tacky) without any heat or solvent for activation and adheres with light pressure. These tapes usually require a release agent on their backing or a release liner to cover the adhesive. Sometimes, the term "adhesive tape" is used for these tapes. Many pressure-sensitive adhesive tapes exhibit triboluminescence, observable in a dark room, when peeled off a dispenser roll or other surface.
 Water activated tape Water activated tape, gummed paper tape or gummed tape is starch- or sometimes animal glue-based adhesive on a kraft paper backing which becomes sticky when moistened. A specific type of gummed tape is called reinforced gummed tape (RGT). The backing of this reinforced tape consists of two layers of paper with a cross-pattern of fiberglass filaments laminated between. The laminating adhesive had previously been asphalt but now is more commonly a hot-melt atactic polypropylene.
Gummed tapes are described in ASTM D5749-01(2006) Standard Specification for Reinforced and Plain gummed Tape for Sealing and Securing. Water-activated tape is used for closing and sealing boxes. Before closing corrugated fiberboard boxes, the tape is wetted or remoistened, activated by water. The tape is mostly 3 inches (7.5 cm) wide. Heat sensitive tape Heat activated tape is usually tack-free until it is activated by a heat source.
It is sometimes used in packaging, for example, a tear strip tape for cigarette packs. Conversely, thermal release tape, such as REVALPHA by Nitto Denko, loses its tack and fully releases when heated to a certain temperature. This type of tape is used often in the semiconductor industry. Drywall tape Drywall tape is paper, cloth, or mesh, sometimes with a gummed or pressure-sensitive adhesive. It is used to make the joints between sheets of drywall materials.

Rapid typing on your own laptop computer is a very helpful ability that could are available handy afterward for the duration of your vocation. It is actually not having said that a simple ability to get most personal computer users typing at mediocre speeds and even following quite a while of owning these types of a machine they nevertheless have remained for the identical typing velocity they had every time they to start with purchased the device.See Also: Free Pregnancy Test El Paso
No-one can prevent using the pc for the reason that laptop or computer has become a software currently. Much as people today may possibly pleasure them selves on their own very good typing, but sadly not all of these are born typists. Additionally they have skilled the very long typing method from becoming typing novices to specialist typists in addition. Not surprisingly, it really is a wise choice to select a great typing tutor once they start to figure out how to kind. Especially for you, for a newbie, opt for a very good typing tutor is intending to pick out a good instructor.
BOPP Packing Tape Adhesive Duct Tape Super Clear Tape Colored Packing Tape Adhesive Foam Tape BOPP Jumbo Rolls Stationery Tape Printed Packing Tape Double Sided Adhesive Tape Invisible Adhesive Tape Marking Tape Rainbow Tape PVC Warning Tape Low Noise Adhesive Tape Cloth Adhesive Tape Masking Tape Kraft Paper Tape PVC Electrical Tape Aluminum Foil Tape Washi Tape Adhesive tapes essentially consist of a material cut into narrow strips and coated on either one side or both with adhesive.
There are numerous types of materials used, such as plastics, textiles, different types of papers, or metal sheets, such as aluminum. Also, adhesive tapes are available in various shapes and sizes, suited for any application. Numerous types of adhesives are also used, such as temporary glues, high durability glues or hardening glues. The main component of an adhesive tape is the glue, which needs to be pressure sensitive to allow sticking on different surfaces easily.
This type of glue was invented by Dr. Horace Day, an American surgeon, in 1845, while trying to find an effective surgery bonding glue. Oscar Troplowitz, a German inventor working for Beiersdorf AG, invented a textile patch which had a gluey surface on one side, named Leukoplast. The first tape dispenser, an ingenious tool which can ease the use of adhesive tapes, was invented only in 1932, by John A Borden, an engineer working for 3M, a major chemical company.
Scotch tape, the first translucent tape, was developed in 1930, while the first masking tape was launched in 1925. Most adhesive tapes work by applying light pressure on a surface and many tapes exhibit triboluminescence, easily observable in dark rooms. Essentially, light is generated when the tape is dispensed and applied on the surface. This phenomenon is not fully understood and it is believed that it is created by small electrical discharges when peeling off the tape.
Here is a list of some of the most common types of adhesive tapes Pressure sensitive tapesAbbreviated as PSA, this type of adhesive tape consists of a sticky tape, one sided or double sided, which is applied by light pressure. The materials used for the tape range from paper, plastics, films, textiles or cloths, metal sheets or composite materials. The tape is sticky as it is, meaning that it works without thermal application or any other related chemicals, such as solvents or acids.
A release liner or other release agents are used on the backing of the tape to prevent sticking before the peeling process. Water activated adhesive tapesKnown also as gum paper tape or gum tape, this type of tape consists of sheets of Kraft paper with and added starch glue or animal glue. The tape becomes sticky and adheres to surfaces only after applying water. Tapes are available in simple layers, double layers or reinforced with fiberglass filaments.
The adhesives used can be asphalt or hot melted polypropylene. Water activated adhesive tape can be used for closing boxes, envelopes or other receptacles. Heat activated tapesThis type of adhesive tapes is activated when a heat source is applied. They are extensively used when sealing boxes and packaging, such as cigarettes packaging. Other types of thermal tapes can be released when heated. These are used mainly in the semiconductor industry, where special care must be given to small delicate components.
