Identification of PVC Conveyor Belts and PU Timing belt  
  Most people would like synthetic leather than leather: PVC, PU leather collectively referred to as artificial leather or imitation leather conveyor belting. Chinese called PVC PVC PVC main components, PU Timing belt polyurethane referred to the Chinese called polyurethane. Is a kind of plastic, but two products of the manufacturing process is different.
PVC leather in the manufacturing process must first melt the plastic particles mixed into a paste, evenly coating thickness required in the T / C knitted fabric substrate, and then the foam into the foam furnace, it has to adapt to production of different products and Rubber timing belts different requirements of flexibility, while the baked surface treatment (dyeing, embossed, polished, extinction, grinding raising, the automotive timing belt main product in accordance with specific requirements for a industrial timing belt).

PU leather in the manufacturing process more complicated than the PVC leather, PU at the end of the tensile strength of cloth is a good canvas PU material, which can be coated on Rubber V-belts top of the base fabric, but also can be included in the middle of the bottom cloth, so that the outside fabric is not in the end there. Than the physical properties of PU leather PVC leather, anti twists and turns, good flexibility, tensile strength Wrapped V-belt, with the permeability (PVC-free). PVC leather tread pattern rolls through the hot steel made; PU leather with a pattern paper pattern is affixed to first heat, pressure in the semi-finished leather surface, waiting for the paper to cool before the separation of leather, so the surface treatment. PU leather PVC leather prices than more than Variable Speed V-belt twice as high in some special requirements of PU leather PVC leather than the price of 2-3 times higher. PU leather needed for the general pattern of 4-5 times will come only with paper scrapping; endless conveyor belts pattern roll long life cycle, thus cost more than PVC leather PU leather ones. It is closer to the cortex of fabric, not the nature of plasticizers to achieve soft, so it will not harden, become brittle, while rich colors, patterns range of benefits, the price cheaper off than leather fabric. We all know the old luxury brand bags LV fabric flowers, old flowers is actually a part of the conveyor belt for general purpose fabric special pearl paint brush on the canvas, then special treatment is made, this prescription is said to remain confidential, the Japanese intent to buy, but wish for . Taiwanese people have worked out a formula and process that will ultimately prove to be a virtual sub-Ukraine. LV fabric is very resistant, and cold resistant conveyor belt even this LV bag is a breakdown of users, with the skin has rotted, and even some of the old flowers as good as new, makes no excuses for the package, but having said that, bought the package LV and, usually, if not need an excuse for the package.
PU, PVC's way easier to distinguish abrasion resistant conveyor belts, from the bottom corner to see PU thick PVC fabric than many (Figure 1-2), also has different feel, PU's soft number; PVC hard some of the feel; also use of fire to burn, PU PVC smell than the taste of a lot to light.
