Core Product Advantages
High Rigidity and Good Toughness Balance
The Chimei PA - 757K has a well - balanced high rigidity and good toughness. Its high rigidity enables it to withstand large external forces without significant deformation. For example, in home appliances such as refrigerator shells and washing machine components, it can maintain a stable structure during long - term use. The balanced toughness ensures that the product will not crack easily when subjected to impacts. In automotive interior parts like door handles, it can resist impacts from normal use and minor collisions, providing long - term reliability. The bending modulus of this material reaches 2.2 - 2.4GPa, which is a strong guarantee for its high - quality performance.
High Gloss Surface
It features a high - gloss surface without the need for additional spraying. This property is very suitable for products with high appearance requirements. In beauty packaging, such as cosmetic boxes and perfume bottle caps, the high - gloss surface can enhance the brand image and product value. In consumer electronics, like TV front shells and computer monitor casings, it can provide a sleek and modern look, meeting the aesthetic needs of consumers. The high - gloss surface also makes the product easier to clean and maintain, which is very important for products in daily use.
Excellent Processing Performance
Chimei PA - 757K has excellent processing performance. It can be processed by injection molding, and the processing parameters are relatively flexible. Before processing, it only needs to be dried at 80 - 85°C for 2 - 4 hours, and the parameters can be adjusted according to the actual humidity and the proportion of recycled materials. The injection machine barrel feed section temperature is recommended to be set at 180 - 220°C, the compression section and nozzle section at 190 - 230°C, and the mold temperature at 30 - 70°C. This wide range of processing parameters allows for easy adjustment during production to ensure the quality of the molded products. In addition, it supports secondary processing such as painting, coloring, surface metal spraying, electroplating, and welding, and can be blended with other resins such as PC, PVC, and PA, providing more possibilities for product customization and function expansion.
Environmental - friendly and Compliant with Standards
This product is made of environmentally friendly materials and complies with various international environmental protection standards, such as RoHS, REACH SVHC, and UL. It is harmless to the human body and the environment, making it an ideal choice for green manufacturing. In applications such as food and drinking water containers, it can ensure the safety of food contact. In the production process, it also meets environmental requirements, reducing the impact on the environment.
Main Application Fields
