Silopren LSR1640是一种用于注塑工艺的双组分液体硅橡胶。LSR 1640与LSR 1640相比,生产效率更高,透明度更高,黄变更少,挥发性含量更低。使用这种低粘度LSR,可以通过缩短注入时间和总循环时间来提高生产率。同时,模具的型腔设计也比较复杂,易于注入。此外,更高的透明度和更少的挥发性成分使其最适合消费品。由LSR 1640组成的硫化液的主要特点和优点有以下特点:高流动性、低粘度和短注入时间。低挥发物含量快速固化优异的脱模性能优异的热稳定性好的橡胶类性能优异的压缩永久性优异的弹性高的耐臭氧和紫外线性能优异的耐老化性不易燃烧,不熔化或滴落易着色用LSR色浆满足要求。对于KTW潜在的应用,由于其优异的性能,LSR 1640特别适用于以下弹性制品:密封元件、O型环、塞子、隔膜、键盘、波纹管、减震器、通风口挡板、开关盖、压力锅零件、电缆接头S.O. Silopren LSR®1640 is a two-component liquid silicone rubber for injection molding processes.LSR 1640 shows in comparison to LSR 1640 a higher productivity, higher transparency, less yellowing and low volatile contents. With this low viscosity LSR, it would be possible to increase productivity by reduce injection time and total cycle time. Also, it is easier to inject into the cavity of the mold which is more complicated designed. In addition, higher transparency and less volatile content make it most suitable for consumer products. Key Features and Benefits Vulcanisates consisting of LSR 1640 are distinguished by the following properties: High flowability, low viscosity and short injection time. Low volatiles content Fast cure Excellent mold release Excellent Thermal stability Good rubber-like properties Excellent compression set Excellent resilience High stability to ozone and ultraviolet light Outstanding resistance to ageing Not readily combustible, does not melt or drip Easy-pigmentable with LSR Colour Pastes fulfill the requirement of KTW Potential Applications Because of the outstanding properties,LSR 1640 is particularly suitable for the following elastomeric articles: sealing elements, O-rings, stoppers, diaphragms, keypads, bellows, vibration dampers, air vent flaps, switch covers, pressure cookers parts, cable connectors s.o. |
