Muffler Bush Universal Four~Hole Exhaust Hanging Racing Modified Car Strengthened Material Thickness 25mm

Application: General purpose (dedicated for exhaust installation, sturdy and ble, and shockproof, protective hook)Exhaust hanging 1: Reduce the height of the exhaust and the body and the contact surface2: Effectively reduce the sound of exhaust shaking and shaking3: Effectively reduce the sound produced byping into the car body or the ion its4: If the enclosure is changed, it will hit the exhaust .These are all people who have changed the exhaust without hardening the rubber.problemExhaust suspension material descrtionproduct manualMaterial is polyurethane (PU elastomer for short) two-liquid typePU elastomer characteristicsWhen the hardne is above JIS hardne of 60 degrees, the PU elastomer has much more mechanical strength than other general rubbers.In the range of high hardne, PU elastomer has better elasticity and elasticity than all other rubbers. It can be called the material between rubber and plastic.(1) Elasticity: tensile or compreive stre.(2) Heat resistance: heat generated by internal friction of PU elastomer during continuous compreion.(3) Excellent mechanical strength (when JIS hardne is 60 or more)The molear network structure of PU elastomers is very regular and tidy, while the general rubber is irregular due to the network structure. When it is stretched, it is easy to break due to stre concention. The PU elastomer has a neat network structure and no stre concention, but is uniformly dispersed throughout, so the mechanical strength is extremely rior.(4) It has a high elastic modulus, and it also has sufficient resilience and elongation at high hardne.(5) Has excellent oil resistance, soent resistance and heat resistance.PU elastomer has rior oil resistance, soent resistance, heat resistance, resistance, weather resistance, and ozone resistance than other general rubbers. At the same time, it is fully resistant to non-polar oils and soents, and quite resistant to tic carbohydrates.PU elastomers, like ordinary rubbers, have a reduced strength when they swell in a soent, but when the soent eates, the PU rubber can restore its strength.(6) When d at high temperatures, it is not suitable for .The PU elastomer has a secry bonding, so the temperature has a considerable influence on it. At a temperature of 160 ° C to 180 ° C, the PU elastomer is liable to thermal decomposition. However, under 80 ° C, the PU adhesive still maintains high strength characteristics, and at 120 ° C, there is still no thermal degradation. When it comes into contact with high-temperature working elements, or due to the high-speed load rotation, the PU elastomer will ca internal heating due to compreion, which requires full attention. (Generally, PU elastomers generate very little heat due to exercise).PU elastomers are generally d below 110 ° C.(7) Water resistance, resistance, and alkresistanceIn a 15% alkaline solution, ar boiling for 12 hours or in high temperature ic water, there is little expansion in this case, so the physical properties are only slightly reduced. Ar drying, it can restore the physical properties, that is, it has a reversible phenomenon.
