It can be hard like fiberglass, squishy like upholstery foam, protective like varnish, bouncy like rubber or sticky like glue. Since its invention during the 1940s, polyurethane has been used in a wide range of items, from baby toys to airplane wings, and it continues to be adapted for ...
The melting point of polypropylene is very high compared to many other plastics, at 320°F (160°C), which means that the hot water used when washing dishes will not cause dishware made from this plastic to warp. This contrasts withpolyethylene, another popular plastic for containers, which ...
It has the advantages of polyester such as good elasticity, high modulus, and crisp texture, as well as polyethylene's low melting point, good fluidity, and easy bonding. Therefore, as a better bonding fiber, it can be used in the non-glue cotton industry. Its products are widely used ...

and oil seepage. Lian Zhengzheng and others studied the formula of the Pullulan soft capsule glue. They found that when the Pullulan and Huangyuan glue24.03: 1 was reproduced. At the same time The amount of water is 7.56 times that of the complex glue, and the glue has a maximum dissolvi...
Molecules of plastics, for example, can be made of hundreds or even thousands of individual atoms joined together in incredibly long chains called polymers. Polythene (also called polyethene or polyethylene) is a very simple example of this. It's a polymer made by repeating a basic unit ...
This is a sealant based on non-viscous polymer after solvent evaporation. This type of sealant mainly includes butyl rubber, high molecular weight polyisobutylene, acrylate with a certain degree of polymerization, chlorosulfonated polyethylene and neoprene rubber sealants....
Polyethylene terephthalate (PET): You’ll find this type of plastic is popular for water bottles, food containers, body care containers, and more. It just so happens to be a great alternative for acrylic and polycarbonate, especially if transparency isn’t a huge priority. Polyvinyl chloride ...
