CPCIA stated that in October, the output value of China's oil and chemical industries increased 9.9% year-on-year to RMB 612.17 billion. From January to October this year, the output value of China's petrochemical industry fell 6% year-on-year to RMB 529 billion.
According to an official from CPCIA, “The petrochemical industry is currently facing some challenges, including a continuing weak market, overcapacity, falling investment, and export difficulties.â€
It has excellent physical and mechanical properties, especially excellent impact resistance, high tensile strength, bending strength, and compression strength; good heat resistance and low temperature resistance, stable mechanical properties in a wide temperature range, and size Stability, electrical properties and flame retardancy, can be used for a long time at -60~120℃; no obvious melting point, in a molten state at 220-230℃; high rigidity, high resin melt viscosity; low water absorption, low shrinkage , Small creep, high dimensional accuracy, good dimensional stability, low permeability of the film; self-extinguishing material; stable to light, but not resistant to ultraviolet light, good weather resistance; oil and acid resistance.
Disadvantage
The fatigue strength is poor, stress cracking easily occurs, and the wear resistance is poor. Poor resistance to solvents, not resistant to strong alkalis, oxidizing acids, amines and ketones, soluble in chlorinated hydrocarbons and aromatic solvents, and prone to hydrolysis and cracking in water for a long time.
pc film classification
PC films are divided into: halogen-free flame-retardant PC, black flame-retardant PC, transparent flame-retardant PC, frosted PC, transparent PC, hardened PC, scratch-resistant PC, scratch-resistant PC, printing-grade PC, optical-grade PC
pc film use
1. Flame-retardant pc film is used for power system insulation, disk drive insulation, keyboard insulation, TV/display insulation, and computer motherboard insulation. It is widely used in electronic components, electrical enclosures, switch panels, junction boxes and charger enclosures, automotive instrumentation and panel printing with flame-retardant requirements.
2. Printing grade frosted pc film is suitable for special printing, helmets, signs, nameplates, protective covers, etc.
3. Anti-scratch pc film Uses: window lenses for mobile phones, MP3, MP4, DVD, backlight and other electronic products
In October, the output value of China's petrochemical industry increased by 9.9% year-on-year
According to data released by the China Petroleum and Chemical Industry Association (CPCIA) on Thursday, the output value of China's oil and chemical industries continued to grow steadily in October, buoyed by the recovery in demand.
