Performance of foam sealing strip for imitative Vito cabinet:

1、低密度高填充性

1. Low density and high filling

机柜发泡密封条的密度是较低的一种橡胶，其密度为0.87。加之可大量充油和加入填充剂，因而可降低橡胶制品的成本，弥补了机柜发泡密封条生胶高的缺点，并且对高门尼值的机柜发泡密封条来说，高填充后物理机械能降低幅度不大。

The density of cabinet foam sealing strip is a kind of lower rubber, and its density is 0.87. In addition, a large amount of oil can be filled and fillers can be added, so the cost of rubber products can be reduced, and the disadvantage of high raw rubber price of cabinet foam sealing strip can be made up. Moreover, for cabinet foam sealing strip with high Mooney value, the physical and mechanical energy after high filling is not greatly reduced.

2、耐老化性

2. Aging resistance

机柜发泡密封条有优异的耐天候、耐臭氧、耐热、耐酸碱、耐水蒸汽、颜色稳定性、电性能、充油性及常温流动性。机柜发泡密封条制品在120℃下可长期使用，在150- 200℃下可短暂或间歇使用。加入适宜防老剂可提高其使用温度。以过氧化物交联的机柜发泡密封条可在苛刻的条件下使用。机柜发泡密封条在臭氧浓度 50pphm、拉伸30%的条件下，可达150h以上不龟裂。

Cabinet foam sealing strip has excellent weather resistance, ozone resistance, heat resistance, acid and alkali resistance, water vapor resistance, color stability, electrical performance, oil filling and room temperature fluidity. Cabinet foam sealing strip products can be used for a long time at 120 ℃, and can be used temporarily or intermittently at 150-200 ℃. Adding appropriate antioxidant can increase the use temperature. The cabinet foam sealing strip crosslinked with peroxide can be used under harsh conditions. Under the condition of 50 PPHM ozone concentration and 30% tensile strength, the foam sealing strip of cabinet can reach 150 h without cracking.
                         

3、耐腐蚀性

3. Corrosion resistance

由于机柜发泡密封条缺乏极性，不饱和度低，因而对各种极性化学品如醇、酸、碱、氧化剂、制冷剂、洗涤剂、动植物油、酮和脂等均有较好的抗耐性;但在脂属和芳属溶剂(如汽油、苯等)及矿物油中稳定性较差。在浓酸长期作用下性能也要下降。在ISO/TO 7620中汇集了近400种具有腐蚀性的气态和液态化学品对各种橡胶性能作用的资料，并规定了1-4级表示其作用程度,腐蚀性化学品对橡胶性能的影响。

Due to the lack of polarity and low unsaturation of cabinet foam sealing strip, it has good resistance to various polar chemicals such as alcohol, acid, alkali, oxidant, refrigerant, detergent, animal and vegetable oil, ketone and grease, but poor stability in aliphatic and aromatic solvents (such as gasoline, benzene, etc.) and mineral oil. Under the action of concentrated acid for a long time, the performance will also decline. In ISO / to 7620, the data of the effects of nearly 400 corrosive gaseous and liquid chemicals on the properties of various rubbers are collected, and grades 1-4 are specified to indicate the degree of action and the effect of corrosive chemicals on the properties of rubbers.
