Advantages of non woven bags
Environmental non-woven bag is a green product, tough, durable, beautiful appearance, good air permeability, reusable, washable, silk-printed advertising, marking, long service life, suitable for any company, any industry as advertising, gifts. Consumers get a beautiful non-woven bag at the same time of shopping, and the merchants get invisible advertisement, so the non-woven fabric is more and more popular in the market.
Higher parts, it is difficult to meet the requirements, good surface gloss products.
Mechanical properties of
Polypropylene has high crystallinity and regular structure, so it has excellent mechanical properties.
The absolute value of mechanical properties of polypropylene is higher than that of polyethylene, but it is still a relatively low variety in plastic materials, and its tensile strength can only reach 30 MPa or slightly higher level.
Polypropylene with a large isotropic index has a high tensile strength, but with the increase of isotropic index, the impact strength of the material decreases, but does not drop to a certain value
Temperature and loading rate have great influence on the toughness of polypropylene.
When the temperature is higher than the vitrification temperature, the impact failure shows ductile fracture, and the impact strength value decreases significantly.
The transition temperature from ductile fracture to brittle fracture can be increased by increasing the loading rate.
Polypropylene has excellent resistance to bending fatigue, and its products can be bent 106 times at room temperature without damage.
But at room temperature and low temperature, due to its own molecular structure of high regularity, so the impact strength is poor.
The most outstanding performance of polypropylene is the resistance to bending fatigue, commonly known as plastic.
Polypropylene has good heat resistance, products can be in above 100 ℃ temperature disinfection sterilization, under the condition of not affected by external forces, 150 ℃ and deformation.
Brittle temperature - 35 ℃, 35 ℃ below - will happen embrittlement, cold tolerance than polyethylene.
Reported values for polypropylene glass transition temperature of a 18 qc, 0 qc, 5 ℃, it is also because people with different samples, containing crystalline and amorphous facies proportion is different, make the molecular chains in the amorphous part of different chain length.
Than polyethylene polypropylene melt temperature around 40 a 50%, about 164 an 170 ℃, 100% degree of isotactic polypropylene melting point is 176 ℃.
Polypropylene has a good chemical stability, 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.
It has high dielectric coefficient and can be used to make electrical insulation products heated with the increase of temperature.
Its breakdown voltage is also very high, suitable for electrical accessories.
Good resistance to voltage and arc, but high static electricity, easy aging in contact with copper.
Polypropylene is very sensitive to ultraviolet light, adding zinc oxide, dilauryl thiodipropionate, carbon black or similar opal filler can improve its aging resistance.
Hydrophobic parameter calculation reference (XlogP) : 3.32, the number of hydrogen bonding donor: 03, hydrogen bond receptor number: 34, the number of rotating chemical bonds: 15, tautomer quantity: 6, topological molecular polar surface area (TPSA) : 29.5 to avoid strong oxidizer, chloride, potassium permanganate sealed, a cool and dry place preserve, ensure good ventilation.
