Z86 Type Natural Silica Filler CAS 61790‑53‑2 is high‑purity processed natural siliceous earth mineral filler. With special irregular porous particle morphology and fine particle gradation, it acts as reinforcing extender for rubber and elastomer systems. It enhances rubber hardness, tensile strength and wear resistance, reduces compound shrinkage during curing, improves processing performance, and helps lower raw‑material cost for rubber products.

Product Detail

Overview

Our Z86 Type Natural Silica Filler CAS 61790‑53‑2 is produced from high‑grade natural diatomite ore via crushing, multi‑stage fine grinding, purification and strict particle‑size classification. This mineral filler is specially engineered for rubber and elastomer reinforcement. It can be partially compounded together with carbon black, silica and talcum powder, optimizing mechanical indexes and extrusion‑processing behavior of finished rubber goods.

Key Features

Unique irregular porous particle structure, provides semi‑reinforcing effect for rubber matrix.
Improve rubber hardness, tensile strength, tear resistance and surface wear performance.
Reduce shrinkage rate during vulcanization, enhance dimensional stability of rubber parts.
Good dispersion in natural rubber, SBR, NBR, EPDM and other synthetic elastomers.
Moderate oil absorption value, benefit mixing and calendering processing performance.
Low harmful impurity content, good compatibility with vulcanizing agent, accelerator and other rubber auxiliaries.

Main Applications

General‑purpose industrial rubber goods, rubber gaskets and seals
EPDM, NBR, SBR, NR rubber compound formulations
Extruded rubber profiles, rubber hoses and rubber rollers
Thermoplastic elastomer TPE / TPR blending system
Various elastomer products requiring cost‑effective reinforcing extender

Usage Recommendation

Typical dosage range: 15‑45 phr, adjust according to target mechanical property and hardness requirement.
Add together with other fillers in internal mixer or open mill, ensure sufficient kneading for homogeneous dispersion.
Keep raw material dry before feeding; excessive moisture may cause bubbles inside vulcanized rubber.
Carry out small‑batch lab formula trial to verify vulcanization curve and finished‑product performance before mass production.

Storage & Package

Store in dry and ventilated warehouse, keep bags tightly sealed to prevent moisture absorption.
Standard package: 25kg woven bag with inner PE liner.
