  • Details

PP plastic woven bag is a plastic woven bag manufacturer's packaging product made of polypropylene plastic. Polypropylene plastic is a thermoplastic resin made from the polymerization of propylene. It can be used as a flame retardant for various electrical appliances and polypropylene bags. PP plastic woven bag has some common characteristics of PP and its own characteristics, including light weight, good electrical insulation, good corrosion resistance, easy processing and molding, etc. The specific performance is as follows:

1. Lightweight

PP is usually lighter, and the density of PP woven bags is about 0.9-0.98 g/cm3. The plastic woven fabric commonly used by plastic woven bag manufacturers, if no filler is added, is equal to the density of the plastic. Plastic weaving application Plastic density is 0.9-0.91g/cm3, lighter than water.

2. High breaking strength

PP plastic woven bag is a flexible and high-breaking material used in the production of plastic products. It is related to its molecular structure, crystallinity, drawing orientation, etc. and the type of additives. If the specific strength (strength/specific gravity) is used to measure the plastic braid, it is higher or closer to the metal material.

3. Good chemical resistance

PP plastic woven bags have good corrosion resistance to inorganics and organics, below 110 degrees Celsius, and have no effect on them for a long time. It has strong chemical stability to solvents, grease, etc. When the temperature increases, carbon tetrachloride, xylene, turpentine, etc. will swell. Strong oxides such as fuming nitric acid, fuming sulfuric acid, and halogen will oxidize it. It has good corrosion resistance to strong alkali and general acid.

4. Good wear resistance

The friction coefficient between pp plastic woven bags is small, only about 0.12, which is similar to nylon. To a certain extent, the friction between the plastic woven fabric and other items has a lubricating effect.

5. Good electrical insulation

PP plastic woven bag is an excellent electrical insulator. Because it does not absorb moisture, is not affected by moisture in the air, and has a high breakdown voltage, its dielectric constant is 2.2-2.6, its volume resistance is very high, and the insulation of the plastic braid is good, it does not mean that it is used to Used as insulation material.

6. Environmental resistance

At room temperature, the plastic woven bag is practically free from water erosion. The water absorption within 24 hours is less than 0.01%, and the water vapor permeability is also very low. At low temperatures, it becomes brittle and easily brittle. PP plastic woven bags will not easily mold.
