用于热塑性塑料的聚合物助剂

聚合物助剂 可提高橡胶混炼胶涂料 和热塑性塑料的性能,为终端客户提供关键特性,如在加工过程中提供更好的挤出性,优异的阻燃性,更好的流变性、动态疲劳保护以及更一致的纤维和卤素分散性,可用于各种应用。 

SIDISTAR™ 产品在热塑性混炼胶中具有有趣的特性。由于其形态,它可以改善阻燃性和加工性能。由于 SIDISTAR™ 产品具有协效阻燃特性,广泛应用于多种终端应用,例如电缆护套、屋面卷材和洗烘一体机冷凝器。由于其改进加工的特性,还可用于木塑复合材料、发泡产品和纱线纺纱中。

成核效应

由于我们的产品 SIDISTAR™ 可分散至初级粒子,因此该材料具有成核效应。它可以产生更均匀的泡沫(封闭的泡孔),具有更小的 " 气泡 ",从而可以提高强度、显著改善表面。例如,即使添加少量的 SIDISTAR™产品,硬质化学发泡 PVC 也会变得更加均匀。当发泡 PVC 从挤出机中流出并冷却时,所有充气泡孔都会收缩,在表面形成微小的凹坑。  作为成核剂,SIDISTAR™ 可确保多个位置同时发泡。在整个材料中形成尺寸更均匀的小泡孔,可以降低最终产品的比重。


提高阻燃性

SIDISTAR™ 产品是一种阻燃协效剂,可形成更坚固、更致密的碳化层。在 UL94 测试中,我们的 SIDISTAR™产品可减少烟雾和滴液。事实证明,与其他阻燃剂(ATO、ATH、MDH、APP、磷酸盐和亚磷酸盐)配合使用时,具有更强的协同作用, 提高其阻燃效率。与其他纳米材料相比,我们的产品 SIDISTAR™可以很容易地通过常规设备(如双螺杆挤出机或其他捏合机)分散成初级颗粒。

The effect of SIDISTAR with Mg(OH)2

In halogen free compounds, the flame retardants of choice are mostly minerals such as ATH and/or MDH, polymer base (especially for cable) would usually be EVA and Polyolefins. Here the challenge can be two-fold, very high loadings of minerals could cause extrusion problems, as well as a tendency for running or dripping during burning.

SIDISTAR polymer additive will be your ideal solution to improve the char formation (strength and structure) because of its spherical shape. Due to this morphology, our product SIDISTAR also will improve the extrudability of highly filled compounds.

Halogenated FR systems

Driving costs down

Our product SIDISTAR™ offers the possibility to reduce costs with good FR performance by substituting 50% of the Antimony Trioxide by SIDISTAR™ polymer additive, considered a non-hazardous material.

Halogenated compounds have been around for quite some time in flame retardant applications. Compounds are often based on PVC as polymer (for cable it will be plasticized PVC, where the plasticizer, if not phosphoric, adds to the flammability).

When using polyolefins, either halogenated, or with a halogenated flame-retardant additive (usually containing fluorine, chlorine or bromine, often in combination with ATO). SIDISTAR™ product will strengthen the char and increase the efficiency of the FR additives. In case one already has good FR performance, it can help to reduce the halogenated materials / ATO and thereby reduce smoke, toxic content and in many cases, reduce the costs of the compound, attaining the same performance or better. ATO reduction/replacement up to 50 % is possible.

改进流变性 / 加工性

SIDISTAR TM 产品的微小完美球体使其能在填充混炼胶中发挥 " 滚珠轴承 "的作用。当施加剪切力时,SIDISTAR TM 颗粒将最大程度地减少固体颗粒的接触面积,由于球体未附着在基体上,能够在接触时滚动。  这种现象可以通过降低的挤出背压和混炼能耗来观察。在低用量下,我们的产品 SIDISTAR TM 可减少挤出机 " 口模流涎 " 或 " 积垢 " 。由于 SIDISTAR TM 球体可减少挤出料与口模的摩擦,挤出料会在模芯和外层模腔之间流动得更均匀,这确保了挤出料在接触区域的快速通过,从而避免了材料停滞和过热的风险。由于积垢减少,停机时间和废料减少,产品表面更细腻、更光滑。
