There are several types and grades of rubber crepe, mainly distinguished by the grade and pre-processing of the latex used in their manufacture. [2] Pale latex crepe (PLC) is a premium grade, made from raw field latex. Estate brown crepe (EBC) is made from "cup lump" (raw, naturally coagulated rubber from the collection cup) and other coagula.
This has been referred to as the first scientific paper on rubber. [15] In England, Joseph Priestley, in 1770, observed that a piece of the material was extremely good for rubbing off pencil marks on paper, hence the name "rubber". It slowly made its way around England. In 1764, François Fresnau discovered that turpentine was a rubber solvent.
Crêpe paper is popular for streamers and other party decorations. Props and costume accessories can be made of crêpe paper. It can be soaked in a small amount of water to create a dye for Easter eggs, white cardstock, and other materials. Crêpe paper can also be used to make paper flowers, appliqué, and paper sculpture.
Paper chemicals designate a group of chemicals that are used for paper manufacturing, or modify the properties of paper. These chemicals can be used to alter the paper in many ways, including changing its color and brightness, or by increasing its strength and resistance to water. [1] The chemicals can be defined on basis of their usage in the ...
A bottle of rubber cement, showing a brush built into its cap and a photo about to be cemented to graph paper. Rubber cement (cow gum in British English) is an adhesive made from elastic polymers (typically latex) mixed in a solvent such as acetone, hexane, heptane or toluene to keep it fluid enough to be used.
Tissue paper sheet. Tissue paper, or simply tissue, is a lightweight paper or light crêpe paper.Tissue can be made from recycled paper pulp on a paper machine.. Tissue paper is very versatile, and different kinds are made to best serve these purposes, which are hygienic tissue paper, facial tissues, paper towels, as packing material, among other (sometimes creative) uses.
Unlike the normal papermaking process, air-laid paper does not use water as the carrying medium for the fibre. Fibres are carried and formed to the structure of paper by air. The air-laid structure is isotropic. The raw material is long fibered softwood fluff pulp in roll form. The pulp are defibrized in a hammermill. Defibration is the process ...
