Z86 Type Reinforcing Filler CAS 61790‑53‑2 is high‑purity fine‑ground natural siliceous earth filler with narrow particle‑size distribution. Optimized particle size avoids coarse grit defects for thin‑wall rubber products. As semi‑reinforcing extender for rubber membrane and thin‑wall rubber parts, it upgrades tensile strength, tear resistance and puncture resistance, reduces vulcanization shrinkage, improves surface smoothness of thin rubber film, adapts to calendering, dipping and extrusion cr

Product Detail

Overview

Our Z86 Type Reinforcing Filler CAS 61790‑53‑2 is produced from premium diatomite ore via deep purification, ultra‑fine milling and multi‑stage precise classification. Oversized particles are strictly removed to prevent pinholes and surface blemishes on ultra‑thin rubber membrane. This grade is purpose‑developed for membrane and thin‑wall rubber parts. It can be combined with carbon black or precipitated silica to balance mechanical performance and production cost for thin elastomer goods.

Key Features

Strictly controlled fine particle size, minimize pinhole, grit and surface defect risks for thin‑wall rubber membrane.
Deliver semi‑reinforcing performance, improve tensile strength, tear strength and puncture‑resistant property of rubber film.
Lower vulcanization shrinkage rate, enhance dimensional stability of thin‑walled rubber components.
Good dispersion in NR, NBR, EPDM and other elastomer systems, uniform filler distribution inside thin rubber matrix.
Adapt to calendering, dipping and extrusion processes for thin‑film rubber production.
Low soluble impurity content, good compatibility with vulcanizing agents, accelerators and other rubber auxiliaries.

Main Applications

Industrial rubber membrane and diaphragm parts
Thin‑wall calendered rubber film
Dipping‑formed thin rubber protective sleeves and covers
Light‑duty thin‑wall sealing rubber components
Delicate elastomer articles requiring smooth surface and good mechanical performance

Usage Recommendation

Typical dosage: 10‑35 phr, adjust according to target mechanical index and membrane thickness requirement.
Add in internal mixer or open mill, ensure sufficient kneading to realize homogeneous dispersion.
Incoming sieve inspection is strongly recommended to eliminate occasional coarse impurities.
Raw material must be fully dried; excessive moisture will generate bubble defects inside thin rubber membrane.
Carry out lab compounding and small‑scale vulcanization test before mass manufacturing.

Storage & Package

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