Protective film characteristics

- Oct 18, 2017 -

Protective film characteristics:
The protective film is milky white or yellow in front of the highly crystalline polymer, the surface smooth and shiny. Resistant  to creep, fatigue resistance, good resistance to friction and  dimensional stability, low wear and high hardness, with the greatest  toughness in thermoplastic; electrical insulation performance, by the  temperature of small, but poor resistance to corona. Non-toxic,  weather resistance, good chemical stability, low water absorption,  resistance to weak acid and organic solvents, but not resistant to hot  water immersion, alkali.
 1. The  thermal deformation temperature of the protective film and the long-term  use temperature are the highest among the thermoplastic general  engineering plastics;
 2. Because  of the high heat resistance, the protective film is immersed in the  solder bath at 250 ℃ for 10s, and it is not deformed and does not change  color. It is especially suitable for the preparation of soldering  electronic and electrical parts.
3. Bending  strength of 200MPa, elastic modulus of 4000MPa, creep resistance and  fatigue is also very good, high surface hardness, mechanical properties  and thermosetting plastic similar;
4. Protective film is the lowest price of engineering plastics, with a high price.
