Features and uses of pp sheet production line

PP board product name: Copolymer PP material has lower heat distortion temperature (100 ℃), low transparency, low gloss, low rigidity, but has stronger impact strength. Strength of PP

It increases as the ethylene content increases. The Vicat softening temperature of PP is 150 ° C. Due to its high crystallinity, this material has good surface stiffness and scratch resistance. PP does not suffer from environmental stress cracking. Generally, PP is modified by adding glass fibers, metal additives or thermoplastic rubber. The flow rate MFR of PP ranges from 1 to 40. Low MFR PP materials have better impact resistance but lower ductility. For materials of the same MFR, the copolymer type is stronger than the homopolymer type. Due to crystallization, the shrinkage of PP is quite high, generally 1.8 ~ 2.5%. And the directional uniformity of shrinkage is much better than materials such as PE-HD. Adding 30% glass additives can reduce the shrinkage to 0.7%. Both homopolymer and copolymer PP materials have excellent moisture absorption resistance, acid and alkali corrosion resistance, and solvent resistance. However, it is not resistant to aromatic hydrocarbons (such as benzene) solvents, chlorinated hydrocarbons (carbon tetrachloride) solvents, and the like. PP is not as resistant to oxidation at high temperatures as PE.

Features and uses of pp sheet production line

The screw of the PP sheet production line is designed with special mixing function and high plasticizing capacity. The hanger plate die of the PP sheet production line uses a special double-throttle design to make the thickness adjustment of the sheet more accurate. Temperature control can accurately control the plasticizing process and sheet Thickness, flatness.The uses and characteristics of the PP sheet production line are:

1 The screw is designed with special mixing function and high plasticizing ability.

2 The hanger-type mold uses a special double-throttle design to make the thickness adjustment of the plate more accurate.

3 Temperature control can precisely control the plasticizing process and the thickness and flatness of the plate.

4 Three-roller calender adopts horizontal, vertical or 45-degree tilt.
