PC JH-9330, a special cold-resistant siloxane PC torch polycarbonate instead of SABIC EXL9330 photovoltaic connector, has excellent low-temperature impact resistance, chemical resistance and environmental stress resistance, as well as good mechanical properties, heat resistance, weather resistance, fluidity and flame retardancy. In general mechanical properties, PCT test and F1 test, the performance of the products can be equal to or even better than that of similar products abroad. Because of the excellent performance of PC JH-9330BK1A068, it can be used in photovoltaic connectors, new energy vehicle charging case and other demanding products.
PC plastics, the scientific name is polycarbonate, is a high molecular polymer containing carbonate group in the molecular chain. According to the structure of ester group, it can be divided into aliphatic, aromatic, aliphatic-aromatic and other types. The application of aliphatic and aliphatic-aromatic polycarbonates in engineering plastics is limited because of their low mechanical properties. At present, only aromatic polycarbonate has been industrialized. Due to the structural particularity of polycarbonate, it has become a general engineering plastics with rapid growth among the five engineering plastics.
Application of PC in automobile
Polycarbonate can meet the high performance requirements of material toughness, strength and heat resistance of automobile interior parts. The application of these materials in automotive interior decorations has the irreplaceable advantages of the following other materials:
1) excellent impact resistance and impact strength in thermoplastic plastics.
2) good finishing and adhesion to the covering film.
3) high dimensional stability;
4) integrate parts installation into one.
5) design and processing are highly flexible applications.
6) the coefficient of linear expansion is low and the coefficient of thermal expansion is small.
