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.
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 ...
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.

It slowly made its way around England. In 1764, François Fresnau discovered that turpentine was a rubber solvent.
Pressing the sheet removes the water by force. Once the water is forced from the sheet, a special kind of felt, which is not to be confused with the traditional one, is used to collect the water. When making paper by hand, a blotter sheet is used instead. Drying involves using air or heat to remove water from the paper sheets.

Rubber Technology is the subject dealing with the transformation of rubbers or elastomers into useful products, such as automobile tires, rubber mats and, exercise rubber stretching bands. The materials includes latex , natural rubber , synthetic rubber and other polymeric materials, such as thermoplastic elastomers .
