Description
| SKF silica gel (lips sealed Code: S) for high / low temperature and low friction applications. Silicone seals in the -100 �� to 325 �� F (-73 �� to 163 ��) temperature range. The high oil absorption of silicone rubber to minimize friction and wear. But no matter what, with the oxidation of oils, extreme pressure additives, and wear some of the compatibility of dirt poor. Should not be used without lubrication silicone. Long Life Long Life (FKM) (seal lip Code: V) for the maximum temperature range and resistance to chemicals in the workplace and quality seal lip material. LongLife material can be -40 �� to 400 �� F (-40 �� to 204 ��) in the temperature range, and resistance to most special lubricants and chemicals, and these special lubricants and chemicals will destroy nitrile, Polyacrylate rubber or silicone rubber. This high-quality wear-resistant material has excellent high temperature performance and abrasion resistance. LongLife compound can be used without lubrication, but only intermittent work. It should be noted that, although fluoride polymer (such as FKM, and PTFE) are high temperature materials, but in extreme temperatures will be thermal decomposition, and produce containing hydrogen fluoride (HF) of the harmful smoke. The bear and temperature: ? Fluoroelastomer (FKM) - 600 �� F/316 �� ? polytetrafluoroethylene (PTFE) - 700 �� F/371 �� In the possible case of such a high temperature, should be referred to the cooling component parts, namely, wear PVC gloves with lime (calcium hydroxide) for dipping, until the PH value is recognized as neutral, and then discarded. PTFE (seal lip Code: T) at -100 �� to 500 �� F (-73 �� to 260 ��) temperature range, compared with ordinary rubber, PTFE dielectric with a wider range of resistance. If you add the appropriate packing, PTFE can have excellent mechanical properties, low friction and good wear resistance. Ethylene propylene (sealed lips Code: M) This is an under natural conditions, water, corrosive substances and steam used in the special plastic material. It has very good resistance to natural aging and anti-ozone properties. Proposed -40 �� F to 300 �� F (-40 to 149 ��) temperatures used. This type of compound often associated with phosphate (fire) water-based lubricants and hydraulic fluids used together, can be anti-polar solvents such as methyl ethyl ketone and acetone, but also anti-silicone oil and grease, acid and alkaline solution and alcohol and brake fluid. Deformation has a good, cold bending, abrasion resistance and tensile strength. No contact with mineral oils, petroleum solvents or aromatic fuels. |
