What is High Impact Polystyrene? HIPS, a form of polystyrene plastic, is combined with polybutadiene to increase its strength and versatility. In its original form, PS is a homopolymer, which results in a more brittle material. As high impact polystyrene, it is a copolymer which offers more ...
Water-soluble polyester resin is a commonly used type of polyester resin. It is an adhesive that can be dissolved in water, making it easy to use and suitable for bonding various materials. This type of resin is often utilized in crafts, DIY projects, and household repairs. It can also be...
2. 选项分析: * A. 它们生产成本太高 - 这与负面环境影响无关。 * B. 它们不能保温 - 这与负面环境影响无关。 * C. 它们需要大约 500 年才能分解 - 这是一个重要的负面环境影响,因为这会导致垃圾填埋场的垃圾增多和环境污染。 * D. 它们难以回收 - 这是一个重要的负面环境影响,因为这会导致垃圾...
What is the difference between PEEK and PEKK? Both are semi-crystalline thermoplastics, but their degree of crystallinity highly depends on the way they are processed.
Polystyrene (PS): Toys, foam Polytetrafluoroethylene (PTFE, Teflon): Non-stick pans, electrical insulation Poly(methyl methacrylate) (PMMA, Lucite, Plexiglas): Face shields, skylights Poly(vinyl acetate) (PVAc): Paints, adhesives Polychloroprene (Neoprene): Wet suits...

With the low dielectric loss, high insulation resistance, but large temperature coefficient, the polystyrene film capacitor can be used in high-frequency circuits. Applications of Polypropylene capacitor CBB capacitors are generally used in: high-frequency pulse occasions, AC occasions, high stability ...
Also there is a kind of polymer material called plastic. It is in ourwater bottles, cell phone cases, glasses,and many other things.And the most ordinaryplastics arepolyethylene,Polypropylene, andPolystyrene; for example,at the bottom of our bottles, we can see the raw material,most of water...
is not generally recycled. Polypropylene is coded as number 5 and is a hard plastic used for long-term food storage containers. It is also used to make pipes for plumbing. The last type of plastic is number 6, polystyrene. This foam-type material is used in egg cartons and disposable ...
