High-Purity Electronic-Grade Methyltrichlorosilane

Siwin-M1E

Electronic-grade Methyltrichlorosilane

Description

Siwin-M1E is an electronic-grade methyltrichlorosilane produced through dedicated distillation and purification. It combines stable M1 purity with ultra-low trace-element levels and is intended for high-purity organosilicon and semiconductor-related silicon chemical applications where boron and metallic impurities must be closely controlled.

Properties

Siwin-A110 used as a surface modifier in fillers and pigments. it can improve the dispersibility of the filler and the mechanical properties – such as flexural strength, tensile strength and modulus - of the composites. The silane also reduces the filler's sedimentation tendency in the uncured polymer. It can also greatly increase water (vapor) and corrosion resistance.

Applications

Recommended as a high-purity silicon chemical intermediate for semiconductor-related materials, electronic-grade organosilicon intermediates, high-purity methylalkoxysilanes, specialty silicone resins and other processes sensitive to boron or metallic contamination.

Package

Available in T14 ISO tanks. Typical net weight is approximately 22,000 kg per tank, subject to tank payload, filling ratio, loading conditions and applicable transport regulations. Other packaging is subject to technical and safety evaluation.
