Diatomaceous Earth CAS 61790‑53‑2 is purified natural amorphous silica mineral powder. Thanks to its special porous irregular particle morphology, it works as reinforcing and extending filler in rubber and sealant industry. It can enhance rubber hardness, tensile performance and wear resistance, reduce formulation cost, meanwhile improve thixotropy and anti‑sagging property of sealant, widely used in rubber parts, gaskets and construction sealant products.

Product Detail

Overview

Our diatomaceous earth CAS 61790‑53‑2 is processed from natural diatomite ore with impurity removal and particle‑size classification. It is designed as multi‑purpose functional filler for rubber reinforcement and sealant additive. Compared with traditional heavy‑duty fillers, it offers good reinforcing effect and excellent processing compatibility. It helps optimize physical indexes of finished rubber and sealant products while lowering overall production cost.

Key Features

Special porous particle structure provides partial reinforcing effect, improve rubber hardness, tensile strength and wear resistance.
Good dispersibility in rubber matrix and sealant base polymer, less agglomeration during kneading and mixing.
Improve thixotropy and anti‑sagging performance of sealant, avoid flowing during vertical construction.
Stable chemical property, compatible with natural rubber, synthetic rubber and various sealant resin systems.
Low oil absorption value, beneficial for controlling compound viscosity in mixing process.
Cost‑effective extending filler, replace partial carbon black, talcum powder to reduce raw material expense.

Main Applications

General rubber products, rubber gaskets, rubber hoses, rubber rollers
EPDM, NBR, SBR and other synthetic rubber formulations
Construction sealant, gap‑filling sealant, adhesive sealant
Waterproof sealant for building and industrial assembly
Other polymer composite requiring inorganic reinforcing filler

Usage Recommendation

Suggest dosage for rubber: 10‑40 phr, adjust according to target hardness and mechanical requirements.
Suggest dosage for sealant: 8‑25% by weight, cooperate with other reinforcing fillers.
Fully knead and mix with rubber compound or sealant base material to guarantee homogeneous dispersion.
Keep raw material dry before feeding; excessive moisture may cause bubbles inside finished products.

Storage & Package

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