N85 Reinforcing Filler CAS 61790‑53‑2 is high‑purity natural siliceous earth processed by fine grinding and particle classification. Featuring porous particle structure, it provides reliable semi‑reinforcing effect in rubber and elastomer compound. It increases rubber hardness, tensile strength and wear resistance, reduces vulcanization shrinkage, optimizes calendering, extrusion and molding processing behavior. Compatible with NR, SBR, NBR, EPDM and TPE systems, it effectively cuts raw‑material

Product Detail

Overview

Our N85 Reinforcing Filler CAS 61790‑53‑2 is refined from high‑grade natural diatomite ore via impurity removal, ultra‑fine grinding and precise particle‑size screening. This cost‑effective semi‑reinforcing mineral filler is engineered for rubber compound and elastomer manufacturing. Oversized grit particles are strictly controlled to decrease surface defects of finished rubber parts. It can be compounded with carbon black, precipitated silica and talc to balance mechanical performance and production cost in various rubber formulations.

Key Features

Good semi‑reinforcing capability, enhance hardness, tensile strength and wear resistance of vulcanized rubber.
Reduce vulcanization shrinkage rate, greatly improve dimensional stability of molded and extruded rubber parts.
Optimize mixing performance, benefit calendering, extrusion and compression‑molding processing operations.
Controlled particle‑size distribution, minimize grit spot and surface blemish for rubber finished articles.
Wide compatibility with natural rubber and multiple synthetic elastomer matrices.
Inert chemical property, well‑matched with vulcanizing agents, accelerators and anti‑aging additives without disturbing vulcanization process.

Main Applications

General‑purpose rubber compound mixing formulations
Extruded rubber profiles, hoses, rubber rollers
Molded industrial rubber components, shock‑absorbing rubber pads
EPDM, NBR, NR, SBR rubber compound systems
TPE / TPR thermoplastic elastomer blending modification

Usage Recommendation

Typical dosage: 15‑40 phr, adjust according to target hardness and mechanical requirements.
Add together with other fillers inside internal mixer or open mill, ensure sufficient kneading for uniform dispersion.
Thoroughly dry raw material before feeding; moisture will cause bubble defects inside vulcanized rubber.
Incoming sieve inspection is advised to eliminate occasional coarse impurities.
Complete laboratory compounding and vulcanization performance test 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.
