Specialized in synthetic resin and synthetic rubber,which has features of wide range and full varieties.Dawn Chemical has established a good ,stable ,long term cooperative relationship with more than 20 large-scale petrochemical companies both in China and abroad,such as SINOPEC,CNPC,Reliance,ExxonMobil,KPIC,KEP ,Sabic and so on.
Relying on its broad mind,honest attitude, steady pace, hard working and pioneering spirits,Dawn Chemical has sold variety of plastic raw materials about 3.5 million Tons in 2021.
| Description |
PP plastic properties:
1, Physical properties: non-toxic, odorless, tasteless, milky white high crystalline density is only 0.9-0.91g/cm3, good stability to water.
2,tThermal performance: has good heat resistance, its products can be disinfected and sterilized at the temperature above 100℃, in the condition of no external force, 150℃ is not deformed. Embrittlement temperature is -35℃, below -35℃ will occur embrittlement, cold resistance is not as good as polyethylene.
3, Chemical stability: Chemical stability is good, besides can be concentrated sulfuric acid, nitric acid erosion, for other kinds of chemical reagents are stable, but the low molecular weight fatty hydrocarbon, aromatic hydrocarbon and chlorinated hydrocarbon can make polypropylene softening and swelling, such as its chemical stability at the same time there is some increase with the increase of the crystallinity, chemical pipe and fittings for the production, so the polypropylene anti-corrosion effect is good.
4, Electrical properties: a high dielectric coefficient, and with the rise of temperature, can be used to make heated electrical insulation products. Its breakdown voltage is also very high, suitable for electrical accessories, etc. Voltage resistance, arc resistance is good, but the electrostatic degree is high, and copper contact is easy to aging.
