High-Purity Insulating Siliceous Earth CAS 61790-53-2 Wire Cable Electronic Plastic Filler (Sillitin V85 Equivalent)
High‑Purity Insulating Siliceous Earth is purified siliceous mineral filler as direct replacement for Sillitin V85. When compounded into wire‑cable and electronic‑grade plastic systems, the mineral powder improves electrical insulation performance. It also reinforces mechanical strength and dimensional stability of cable sheathing and electronic plastic components, satisfying strict requirements for electrical polymer formulations.
Product Overview High‑Purity Insulating Siliceous Earth (CAS 61790‑53‑2, Sillitin V85 Equivalent) is high‑purity refined siliceous earth mineral filler designed for electrical polymer applications. The carefully processed fine powder features low conductive impurity content. After homogeneous dispersion within plastic or elastomer matrix, it boosts electrical insulation performance of the composite material. Meanwhile, this mineral filler enhances rigidity, improves heat‑resistant property and restricts thermal deformation of molded cable and electronic plastic parts. It is widely used for insulating compounds in cable extrusion and technical electronic plastic component manufacturing.
Key Features ‑ Low conductive‑impurity grade delivers reliable electrical insulation for polymer composites ‑ Reinforces mechanical rigidity and improves heat‑deformation resistance of plastic parts ‑ Good thermal stability under cable extrusion processing temperature ‑ Satisfactory dispersion within thermoplastic and elastomer cable formulations ‑ Direct functional equivalent grade for Sillitin V85 insulating mineral filler
Typical Technical Properties ‑ Chemical Type: Purified natural siliceous earth mineral ‑ Appearance: Off‑white fine free‑flowing powder ‑ Particle Size: Refer to TDS ‑ Bulk Density: Refer to TDS ‑ Dielectric Property: Refer to TDS
Applications ‑ Wire‑cable compounding: Insulating filler for cable jacket and insulation layer formulations ‑ Electronic plastic: Functional mineral filler for injection‑molded electronic insulating components ‑ Elastomer insulation: Reinforcing filler for technical insulating rubber parts ‑ Polymer compounding plant: Raw mineral filler for electrical‑grade modified plastic granules
Processing Recommendation Add the siliceous earth filler during high‑speed mixing before extrusion or injection. Adjust feeding proportion based on targeted insulation and mechanical specifications. Ensure adequate homogenizing mixing. Complete lab compounding testing before mass extrusion production of cable materials.
Storage & Handling Store in cool, dry warehouse and strictly protect against moisture. Reseal packaging immediately after opening. Wear dust‑proof mask and protective gloves during handling fine mineral powder.
