Several Rubber Cots On The Characteristics And Applications Of

① Neoprene: applied soft printing rollers, gravure printing rollers, etc. Roller molding molding, film roll forming, winding or compression molding method. Due to poor storage stability of compounds, in the manufacturing process, therefore, should be taken to avoid parked in direct sunlight. While controlled docking of rubber compound temperature conditions.

② NBR: used in the manufacture of printing rubber rollers, food industry rubber rollers, textile printing and dyeing rollers, exposure to solvent-free rollers. Bad ozone resistance of nitrile rubber, therefore processing operations under conditions of high ozone concentration should be avoided. Nitrile rubber and PVC and can beobtained with good resistance to ozone and weather resistance rubber compound.

③ Polyurethane rubber: has outstanding tensile strength, abrasion resistance andcrack resistance characteristics of polyester polyurethane rubbers have good resistance to solvents. In addition, the plastic material in the heat and humidity of the environment, will also have a negative impact on performance. Used for high speed, high pressure polyurethane rollers, focusing on improved dynamic roll removalproblems and crack.

④ Silicone: heat resistance up to 200-250, good resistance to chemical attack, the main drawback is the low tensile strength. Silicone rubber roll typical use heat set the fabric, plastic, heat embossing, calendering, copier fuser. Silicone rollers film roll shape, due to the low intensity, action must be careful.

⑤ Chlorosulfonated polyethylene; high toughness and flexibility. Wear resistance, heat resistance up to 150 degrees, well on a variety of chemicals, oil resistant, has excellent insulating properties. Various methods available other than casting, plasticmaterial to avoid sun exposure in the production process.

⑥ EPDM: in 150-degree heat under the conditions of use, has excellent chemical resistance properties, solvent-resistant, but not resistant to hydrocarbon solvents and oils can be used to create squeeze roller, conveyor rollers, exposure to acetone and solvents inks for printing rollers. Roller wrap molding and extrusion moldingprocess operation note avoid contact with oils and hydrocarbon solvents.
