PP polypropylene resin

a. Production method: high purity propylene as monomer, titanium trichloride as main catalyst, diethylaluminum chloride as cocatalyst, gasoline as solvent, hydrogen as molecular weight regulator, temperature 55-70 ° C, pressure 0.1 The continuous polymerization is carried out in a polymerization vessel under MPa, and the polymer is a suspension, which is washed, separated, dried or extruded by methanol esterification to obtain a granular or powdery homopolymer or a finished copolymer.
b. Product performance: odorless, odorless, non-toxic milky white granular product or powdery product, relative density of 0.90 ~ 0.91. The temperature of 164 ~ 167 ° C. It has excellent mechanical properties, heat resistance, electrical insulation properties, chemical stability, and does not interact with most chemicals. However, the light resistance is poor, easy to age, the impact strength is poor at low temperature, the dyeability is poor, and it needs to be improved by adding additives, blending, copolymerization and the like. Do not dissolve in water, do not absorb water, can be boiled in water, disinfected at 130 ° C, easy to process.
c. Uses: It can be used as electric fan motor cover and electrical insulation materials, household appliances such as TV sets, radio casings, anti-corrosion pipes, plates, storage tanks and equipment linings, building materials, special grades can be used to make washing machine barrels, infusion bottles, etc. It can also be used to make woven bags, packaging films, tying materials and various types of containers, as well as for the production of fibers.
d. Packing, storage and transportation: It is lined with plastic film and woven bag, and the net weight of each bag is 25kg. It should be stored in a dry, cool, ventilated warehouse to prevent direct sunlight. It should not be stored in the open air. Fire-fighting facilities should be available in the warehouse. When transporting, it must not be mixed with sand, cement, coal, metal and other sundries. It should not be mixed with flammable and explosive materials, and should be protected from sunlight and rain during storage and transportation.
