A confetti criss cross typically contains about 12 to 15 rubber bands, arranged in a crisscross pattern. This design can vary based on specific sizes and styles, but that range is common for standard confetti criss cross items. If you're looking for a precise count, it's best to check the manufacturer's specifications.

What makes vulcanised rubber different to an ordinary rubber?

Vulcanised rubber is created through a chemical process that involves heating natural rubber with sulfur, which forms cross-links between polymer chains. This process enhances the rubber's durability, heat resistance, and elasticity, making it more suitable for a variety of applications. In contrast, ordinary rubber lacks these cross-links, resulting in a material that is more prone to degradation, deformation, and lower performance under stress. Overall, vulcanised rubber offers improved mechanical properties and longevity compared to non-vulcanised rubber.


What did vulcanization do?

vulcanisation- when sulfur atoms form cross-links between rubber molecules. vulcanised rubber is used to make car tyres and conveyor belts. :)


What is the ultimate tensile stress of a rubber band?

You must hang weights from a rubberband until it snaps;then divide the total weight by twice the cross-sectional area of the rubber band. ThisÊwill be the Êtensile load of the rubber band.


What rubber is made of?

Nowadays rubber is more commonly made from petroleum but it's also possible to make rubber from the latex extracted from trees (latex is pretty much just sap).Rubber is just a combination of polymers of isoprene units and other natural substances and impurities. It is a build up of the isoprene unit molecules and is not normally made up of other synthetic materials (although sometimes these materials are used to sythesise rubber). Natural rubber comes from the sap of the rubber tree. Today's rubber is mostly a synthetic, formed from substances like latex. jb real rubber comes from the sap of the rubber tree. synthetic rubber does not come from latex, but is made from oilRubber is naturally made from the sap of rubber trees.These grow in tropical climates such as Malaysia. We can also make synthetic rubbers, starting with substances from crude oil. Natural rubber has few uses in its untreated state, being a very soft substance. Examples include insulation and adhesives. Most rubber is hardened by the process of vulcanisation which cross links the molecules to make the substance harder. It then has many applications such as vehicle tyres, air hoses and rainwear.


Is rubber strong?

rubber is not strong on its own but when it is vulcanised,i.e.,heated with sulphur to a definite temperaturefor a known period of time,it becomes strong because sulphur atoms act as bridges between rubber molecules, initiate cross-linking and convert the soft sticky rubber into a hard, elastic mass which can be put to extensive uses such as use in tyres,etc Because it is elastic.
