Introduction

SCIENCE MAJOR INVESTIGATION Which type of 19mm sticky tape is the best? By: Kelvin Tan 10S3 Mr. Tob For the major Science Investigation this year I have decided to test a very commonly used household and office tool. The sticky tape or pressure-sensitive tape. In this specific investigation the different types of sticky tape being tested and investigated are all 18-19mm in length. There is the Scotch 600 clear and transparent tape which is expensive, then an 18mm wide, black electrical tape. A yellowish coloured masking tape, a brown cellophane tape which is 19mm wide and then cheap Officeworks sticky tape which was only 78c which 18mm wide. These tapes all are used for different purposes around the house and some may even have industrial uses. I will test in which conditions and situations is each type of tape performs best and does its job of adhering to the surfaces. The sticky tape is really called adhesive tape , it is used to bond two different surfaces or items. The household sticky tape is mainly made of cellophane on the non-sticky side and can also used to try and repair cracks and keep together splits in various surfaces of different item. The Scotch and Officeworks tape is mainly used for office use such as on paper, or manila folders. The other tapes are used for various purposes around the house and the masking tape is fairly an all-purpose tape. This investigation will test which type of sticky tape is good for whichever situation and environment. ...read more.

A pressure sensitive tape consists of a relatively thin, flexible backing or carrier, coated with an adhesive, which is permanently sticky at room temperature. The tapes can be manufactured with the adhesive coating on one side (single-sided) or both sides (double-sided) of the carrier. Single sided tape Double-sided tape Adhesive tapes are made up of two components: a carrier which is usually paper, plastic, cloth or rubber and an adhesive which is either water or solvent based. Many modern adhesive tapes use pressure sensitive adhesives. The adhesive is coated on the backing and bonds to the target, when you apply pressure to the tape with your finger, a strong adhesive bond is formed. One or both of the sides of the backing is specially treated to provide controlled release or adhesion. Pressure-sensitive adhesives include a variety of natural and synthetic materials, including natural rubber, synthetic rubber, block copolymers, acrylics, silicones, etc., modified in various ways through molecular weight selection, resin additions, oils, fillers, cross-linking agents, stabilizers, pigments and other additives. The majority of today's pressure-sensitive adhesive tapes consist of plastic film backing coated with natural rubber, synthetic rubber or acrylic pressure-sensitive adhesive. Polypropylene, polyester and polyvinyl chloride constitute most of the films currently used. These films are normally formed by extrusion and do not require the use of solvents in forming the film. Other common materials include films (which are typically made from regenerated cellulose, polypropylene or PVC), paper tissues, cloth or even metal foils and can be clear, coloured or printed. ...read more.

Conclusion

The Hot Melt method To make sure the pressure-sensitive tape does not stick to itself , the back of carrier is coated with a release coating, this release coating is needed to make all tapes function properly. The finished products The earliest reference to sticky tape being used can be found in Thomas Mace's "Music's Monument" published in 1676 where lute makers used 'little pieces of Paper, so big as pence or two pences, wet with Glew' to hold the thin strips of sycamore in place during construction of their musical instruments. The first use of "pressure sensitive" tape was in 1845 when a US patent was taken out by Shecut and Day where they used rubber, pressure sensitive adhesive was used in the making of sticky plasters which are put onto sticky bandages to be used during the American Civil War. Major progress in pressure-sensitive adhesive tapes was achieved in the 1920s, when Henry Ford introduced industrial uses of tapes. Masking tapes were used in the spray-painting process, where different coloured cars were assembled. In the 1930s the first cellophane plastic were produced which had a rubber-cement based adhesive. Cellophane Cellophane is the common name for flexible, transparent film made of regenerated cellulose and used principally as a wrapping material. Cellophane is produced by dissolving wood pulp or other cellulose material in an alkali with carbon disulfide, neutralising the alkaline solvent with an acid, extruding the precipitate into a sheet, infusing it with glycerine, and then drying and cutting the sheets to the desired size. Cellophane was invented about 1910 by the Swiss chemist Jacques Brandenberger. ...read more.
