卡槽式木门密封条
常用材质特性(The features of Materials):
一、优质PVC密封条(high qualityPolyviny ChloridePVC):
PVC价格较低,缺点是硬度随温度变化较大,随着时间的延长会变硬变脆,失去弹性。但是经改性后的优质PVC在耐低温性能方面有较大的提升,使用寿命延长。
The price of PVC is cheaper.the hardness is easy to be changed with the temperaturewill become hard and brittle with the extension of time and lose elasticity.But the material we used is modified high quality PVCthere is a great improvement in Itemperature resistance
二、TPE密封条(ThermoplasticElastomerTPE):
俗称热塑性弹性体,价格适中。密度小。硬度随温度变化小,回弹性好,在热空气老化性能(70℃ x24h)的条件下,位伸强度变化率为7.59%,拉断伸长变率变化率为21.7%。耐老化性能,耐温性能优于PVC胶条。
The price of TPE is a bit expensive than PVC.Low density,Hardness will not easy to be changed with temperature good resilience and aging resistance,better than PVC strips.
三、硅橡胶密封条(SiliconeRubber):
成本较高,有突出的耐高温、低温特性,耐臭氧及耐候性能,可适用于高温、寒冷、紫外线照射强烈地区以及中高层建筑。耐老化性能,耐温性能,回弹性能皆优于PVC和TPE密封条。
The price is expensive than PVC and TPE,Excellent temperature resistanceozone and weathering resistance, Well used for high or low temperature areas,stron
