In modern society, we often use PC film, its application field is very large, to our life has brought great convenience. Before use, we want to understand the performance of PC film, you can read the instructions, the content of which is more detailed, more convenient to use. Today xiaobian with you to learn about the knowledge of PC film, respectively as follows:
According to the information learned by the small make up, PC membrane has good heat resistance and low temperature resistance, in relatively wide temperature range has the stable force performance, dimensional stability, electrical properties and flame retardancy, can use for a long time under the 60 ~ 120 ℃; No obvious melting point, in 220-230 ℃ in the molten state; Because the molecular chain rigidity is large, the resin melt viscosity is large; Small water absorption rate, small shortening rate, high scale accuracy, good scale stability, small film permeability; Self-extinguishing data; Stable to light, but not uv light, good weather resistance; Oil resistance, acid resistance, strong alkali resistance, oxidative acid and amine, ketone, soluble in chlorinated hydrocarbons and aromatic solvents, easy to cause hydrolysis and cracking in water for a long time, the disadvantage is due to poor fatigue strength, simple stress cracking, poor solvent resistance, poor wear resistance.
