Now black PC film appeared in social opportunities is more and more, and also in the market can see all kinds of PC film, so in the market for PC film is also very attention, can't say all in the market of PC film is good in quality, and to choose appropriate when choose in their own industry PC film, so, let below small make up to you to understand black PC membrane and the application of PC piece good performance:
First, light is stable, but not uv light, good weather resistance to oil, acid, alkali, oxidation acid and amine, ketone, soluble in chlorinated hydrocarbons and aromatic solvents, for a long time in the water is easy to cause hydrolysis and cracking, the defect is due to poor fatigue strength, simple stress cracking, poor solvent resistance, poor wear resistance.
Second, it has excellent physical and mechanical properties.
Third, Excellent impact resistance, high tensile strength, bending strength, compression strength, small creep, stable size.
Fourth, has excellent heat resistant up to 125 degrees below zero and low temperature resistance, 45 degrees in a wide temperature range have secure mechanics function, scale of safe sex, power function, and the flame retardancy, can use for a long time under the 60 ~ 120 ℃; No significant melting point, melting conditions in 220-230 ℃, because the molecular chain rigidity, resin melt viscosity.
Fifth, the water absorption rate is small, the shortening rate is small, the scale accuracy is high, the scale stability is good, the thin film permeability is small, belongs to the self-extinguishing data.
