The new trend of a new generation of engineering plastics to replace metals The performance of engineering plastics continues to improve, and the use of plastics to replace metals is becoming more common. The new generation of fiber-reinforced plastics, such as Solvay's IXEF, has mechanical properties comparable to those of some metals.

The surface after injection is very smooth and beautiful, and it can also be used for structural appearance parts. Another example is Solvay's AmodelPPA. Some models have a heat distortion temperature up to 310°C and are resistant to hydrolysis, which can be used in high temperature and humid environments. Among fiber-reinforced plastics, long-fiber thermoplastics have also gained popularity at home and abroad in recent years. After molding, the fibers can still maintain a considerable length and entangle each other, so that the finished product has high rigidity and good toughness; With the advantages of stability, light weight and corrosion resistance, long-fiber materials have been widely used in automobiles, aerospace, medical, transportation, sporting goods, household appliances and electronic products. Plastic parts in the current car design already account for 16% of the car's weight. The First Cornerstone (Hong Kong) Co., Ltd. estimates that this percentage will continue to increase to about 25% within five years. This trend makes the new generation of cars more fuel-efficient, less carbon-emitting and more comfortable.

Do you know what an omnidirectional conductive sponge is?

The omnidirectional conductive sponge is a conductive metal plating process based on the sponge. The back of the conductive sponge uses a conductive cloth as the substrate to combine the conductive adhesive with the sponge material, thereby achieving an omnidirectional conductive effect. It uses electroplating on the surface of the sponge to ensure good electrical conductivity, and the outermost nickel layer also increases the corrosion resistance of the material.

Do you know the relationship between conductive cloth tape and conductive cloth?

Conductive cloth adhesive tape is also a kind of adhesive tape made of conductive cloth. Its characteristics are the addition of "glue" characteristics to the conductive cloth, and its important characteristics can be referred to the term "conductive cloth". The "glue" that is commonly desired in the industry is conductive glue, which has a "nickel" component, in order to provide a magnetic shielding effect. However, there are also ordinary acrylic or hot melt adhesives that do not require conductive adhesive, in order to make the conductive cloth have good adhesion.

Where are conductive sponges widely used?

Conductive sponge is a material that mainly uses flame retardant sponge as the base material during the production process; An electronic material made by wrapping a layer of conductive cloth on the surface of the sponge and using a special process.

Are plastic products safe? Can they be heated and used?

Plastic products can be seen everywhere in daily life, but like Ms. Wang, many citizens know very little about the basic knowledge of plastic products. The author interviewed 20 citizens in a number of supermarkets and residential communities and found that 80% of the citizens often use plastic products in their lives, but they do not know how to use plastic materials and how to be safe.

The U.S. plastics processing industry is in a good situation with more optimism

Troy Nix, executive director of MAPP, said that the plastics manufacturing industry has officially recovered from the recession and is moving steadily towards exceeding the pre-recession sales level.
