Polypropylene PP pipe fittings are produced according to QB1929-93 specification. Standard DN15-800mm, nominal pressure 0.4-1.6MPa, the selection of copolymerization grade PP pipe fittings special material production. The products have the characteristics of corrosion resistance, high strength, leakage resistance, small internal resistance, tensile strength, bending resistance, low cost, long life, convenient equipment repair, etc., widely used in petroleum, chemical industry, electric power, textile, metallurgy, pharmaceutical, papermaking, food, mining, garbage treatment, construction and other operations, deeply trusted by users. The company can act as PP pipeline equipment construction and counseling, and can process all kinds of PP non-standard parts according to user drawings. Welcome new and old customers to call letters.

At present, PP bottles are mainly molded in one-step injection and pull-blowing (ISBM) and two-step heating and pull-blowing (SBM) forming machines, and PP bottles have the benefits of clear, strong and heat-resistant, and the price is lower than traditional materials.

1.PP bottle can be stored at 100℃ for hot filling, for example, assume that juice and jam products need to be packed at this temperature, and general precautions for pet preform injection molding filling temperature can not be higher than 76℃ glass transition. BOPP bottles are widely used in functional beverage packaging because they can withstand high temperatures above 100t2.

2. The insulation function of PP on moisture is about 5 times that of PET, and the price of PP preformed product production is lower than that of PET preformed product production.

3. Compared with PET, the price of PP is 10%-30% cheaper than PET, the density of 0.9g/cc is less than that of PET 1.35g/cc, and the weight of PP bottle is lighter than precautions for pet preform injection molding. The cycle time of PP bottle is longer than that of precautions for pet preform injection molding, so the production cost is lower.

4. The study shows that after mixing polyolefin prepared by 15% ethylene/metallocene catalyst in Tongming silicon-free copolymer polypropylene, the impact strength of PP bottle can travel from 4.7ft to 7.8ft.

PP bottle than precautions for pet preform injection molding processing speed is slow, the physical characteristics are relatively poor, so it is not widely used. But increasingly open machinery, bottle planning, improved resins and special additives allowed these problems to be overcome. With the success of the development of Tongming modification-nucleating agent, the high Tongming PP packaging bottle can be produced by adding 0.1%-0.4% sorbitol xylene (benzaldehyde) nucleating agent in general PP through blowing, blowing, injection, kneading and other methods. The product can be widely used as fresh juice, dairy drinks, beverage bottles and so on.

PP bottle has good temperature resistance function, sensitive bottle shape planning, excellent performance in safety, hygiene and the taste of the contents, and is cheaper than PET, PS, PE and other materials. The continuous opening of modified resins, anti-reflection agents and mechanical equipment technology makes PP containers can replace glass, PET and PVC containers, and has a broad market prospect.

Therefore, we can guess that PP bottles will become a strong competitor of PET blow molded bottles in beverage packaging, PP bottles produced by extrusion blow molding can be used to package mineral water and beverages, and PP bottles produced by stretch blow molding molds are mainly used for water, isobaric water and sports drink packaging. FIP manufacturers and related product manufacturers are defeating the shortcomings of PP, and the application of PP bottles in beverage packaging malls has gradually approached precautions for pet preform injection molding.
