What Is The Distinguishing Feature Of Chemical Woven Bag Cylinder Cloth
Posted by roylakosyang on March 3rd, 2016
Woven bag cylinder cloth is used for packing, and its raw material is usually polyethylene, polypropylene and other chemical plastic raw materials. And we mainly introduce chemical woven bags with polypropylene as the main raw material.
Woven bag cylinder cloth is made by extrusion, stretching into flat wire, then through weaving, the following to introduce the material characteristics of woven bag cylinder cloth.
Mainly for the pp woven bag cylinder cloth production. Polypropylene is a thermoplastic by polymerization of vinyl resin, industrial products and rules as the main component. Polypropylene also includes copolymer of propylene and a small amount of ethylene. Usually a transparent colorless solid, odorless drug-free. Because of its neat and high crystallization structure, so the melting point can be as high as 167 ℃. Heat resistance, corrosion resistance, products available steam sterilization is its outstanding advantages. Density is small, it is the lightest of general plastics. Drawback is the low temperature impact resistance is poor, easy ageing, but can be respectively by modified to be overcome.
Polypropylene PP, PP material with low thermal deformation temperature (100 ℃), low transparency and gloss, low rigidity, but have stronger impact strength, impact strength of PP increased with the increase of ethylene content increased. PP vicat softening temperature is 150 ℃. Due to the high crystallinity, the surface of the material stiffness and resistance to scratch characteristics very well. PP environmental stress cracking problems.
