PP is polypropylene. Polypropylene is a non-toxic, odorless, tasteless, milky white highly crystalline polymer with a density of only 0.90--"0.91g/cm3, which is one of the lightest varieties of all plastics.Polypropylene also includes copolymers of propylene and a small amount of ethylene. Usually translucent colorless solid, odorless and non-toxic.
Due to the regular structure and high crystallization, the melting point can be as high as 167 ° C. Heat resistance, corrosion resistance, products can be steam disinfection is its outstanding advantages. Low density, is the lightest general purpose plastic. The disadvantage is poor low temperature impact resistance and easy aging, but it can be overcome by modification respectively.
The chemical stability of polypropylene is very good, in addition to being eroded by concentrated sulfuric acid, other chemical agents are relatively stable, but low molecular weight aliphatic hydrocarbons, aromatic hydrocarbons and chlorinated hydrocarbons can make polypropylene soften and swell, while its chemical stability with the increase of crystallinity and improve, so polypropylene is suitable for making a variety of chemical pipes and accessories, anti-corrosion effect is good.
Main use
It is mainly used in the production of various long and short polypropylene fiber, used in the production of polypropylene woven bags, packaging bags, injection molding products, etc., used in the production of electrical appliances, telecommunications, lighting, lighting equipment and TV flame-retardant parts.

Everyone knows the devil is in the details. As for packaging, we prefer durable bags that can fully withstand shock, vibration and pressure changes during transportation. We will choose the corresponding packaging type according to the material,weight, size, shape and volume of the goods. Pay special attention to the packaging should be clean and dry without odor and oil, and there should be no prominent nails, hooks, thorns, etc.
We will choose packing materials such as wooden boxes, pallets, wooden frames, aviation cases, etc. At the same time, foam bubble film stretching film is used to fill or protect the inside and outside of the goods to prevent unnecessary losses caused by movement of the goods or collision with each other.
At the same time, it is necessary to ensure the waterproof and moisture-proof ability of the packaging, and consider the multi-directional customers to let customers buy peace of mind.
Factory delivery strength, arrange special personnel responsible for packaging and shipping, large annual output, loading equipment and transportation advanced convenient, high efficiency.
Sea, land and air transport modes to meet the ultimate needs of customers, is bound to bring superior purchasing experience for customers.
At the same time we constantly improve the quality of packaging, improve packaging methods, reasonable choice of means of transport and transport routes, the development of social transport system.
