Transparent Siliceous Earth Filler is high‑purity refined mineral filler as direct replacement for Minspar 7. Incorporated into silicone elastomer and transparent plastic systems, this mineral powder provides lightweight hardening and reinforcing effect. It improves the hardness and mechanical strength of cured compounds, and retains acceptable transparency for silicone and transparent plastic finished parts.

Product Detail

Product Overview Transparent Siliceous Earth Filler (CAS 61790‑53‑2, Minspar 7 Equivalent) is specially purified siliceous earth mineral filler developed for silicone elastomer and transparent plastic applications. Careful mineral processing reduces coloured impurities. When evenly dispersed within silicone or transparent plastic matrix, the filler offers lightweight reinforcing function, raising shore hardness and tensile strength of cured polymer. It avoids severe loss of light transmission for finished articles. This mineral filler is suitable for high‑performance silicone rubber, transparent technical plastic and soft elastomer compounding.

Key Features ‑ Low‑impurity mineral grade to preserve acceptable transparency of elastomer and plastic parts ‑ Provides lightweight hardening and reinforcing effect for silicone and transparent polymer systems ‑ Improves shore hardness, tensile strength and dimensional stability of cured compounds ‑ Good thermal stability during polymer kneading and moulding processing ‑ Direct functional equivalent grade for Minspar 7 transparent siliceous earth filler

Typical Technical Properties ‑ Chemical Type: Purified natural transparent siliceous earth ‑ Appearance: Off‑white fine free‑flowing powder ‑ Particle Size: Refer to TDS ‑ Bulk Density: Refer to TDS ‑ Refractive Index: Refer to TDS

Applications ‑ Silicone elastomer compounding: Lightweight hardening filler for technical silicone rubber parts ‑ Transparent plastic modification: Reinforcing mineral filler for transparent thermoplastic formulations ‑ Soft elastomer production: Functional mineral filler for non‑opaque elastic components ‑ Polymer compounding plant: Raw transparent mineral filler for custom silicone and plastic compounds

Processing Recommendation Add transparent siliceous earth filler during kneading or high‑speed mixing stage. Adjust filler loading carefully to balance hardness requirement and finished‑part transparency. Ensure sufficient homogenizing mixing. Conduct lab compounding trials before large‑scale polymer production.

Storage & Handling Store in cool, dry warehouse and strictly avoid contamination and moisture. Reseal packaging after opening. Wear dust‑proof mask and protective gloves while handling fine mineral powder.
