Molding process: the mold cost is relatively high, the advantage is that it can accurately ensure the thickness and size of composite materials, and has two components with smooth surface. The components commonly used in...
PMI foam is made by heating methacrylic acid and methacrylonitrile copolymer board and foaming. In the process of foaming the copolymer board, the copolymer is transformed into polymethacrylimide. The foaming temperature...
1. The main application of PET polyethylene terephthalate: the most common is to be used as a beverage bottle, screen protection film and other transparent protection films. PET can also be spun, which is what we often c...
(1) Polystyrene material Polystyrene foam board is compounded with a layer of hips on both sides, and a composite material with higher rigidity is obtained. For different resins, different densities, and types of rohacel...
1 Building materials Due to its light weight per unit volume, soundproof, vibration-proof, fire-resistant, non-combustible, heat-preserving and other properties, aluminum foam can be used to construct non-load-bearing in...
The current frequency of the Qi standard for wireless charging is between 100-200k. At this frequency, the permeability of nanocrystalline is very close to that of cobalt-based amorphous, which is significantly higher th...
