Product Overview

Nano Bentonite Clay CAS 1318-93-0 is organically modified layered silicate nanofiller derived from natural bentonite via cation exchange modification.

Unmodified bentonite is hydrophilic and hard to disperse in rubber. After organic surface treatment, the material becomes organophilic and possesses excellent compatibility with various rubber formulations. In the rubber kneading process, stacked silicate layers can be exfoliated into nanosheets and uniformly distributed within rubber matrix. The interleaved lamellar structure forms tortuous diffusion paths to block gas penetration, greatly enhancing air tightness and air retention capacity of rubber compounds. Besides outstanding gas barrier performance, this product also upgrades tensile strength, thermal stability and dimensional stability. It is a dedicated functional barrier filler for tire inner liner rubber materials.

Product Properties

This product is fine off-white powder with intact layered crystal structure. It exhibits good compatibility with butyl rubber, halogenated butyl rubber and other rubber raw materials for tire inner liner. Nanoscale exfoliation can be realized under proper mixing process parameters. Low impurity content avoids defects such as bubbles and surface cracks of finished rubber products. It features favorable heat resistance and adapts to conventional rubber vulcanization temperature range. Barrier effect remains stable under long-term alternating temperature service conditions.

Core Advantages

Organophilic modification technology. Effectively solve agglomeration and poor compatibility problems of raw bentonite in rubber systems.

Superior gas barrier performance. Remarkably reduce air permeability and improve air holding performance of tire inner liner.

Nanoscale uniform dispersion. Form continuous lamellar barrier network inside rubber matrix.

Comprehensive performance reinforcement. Improve rubber mechanical strength, heat resistance and creep resistance simultaneously.

Excellent processing property. Adapt to conventional rubber internal mixing, open mixing and calendering production processes.

Cost-effective formulation solution. Reach target air tightness indicators with low addition dosage.

Main Applications

Nano Bentonite Clay serves as professional barrier filler for rubber tire inner liner materials. Typical applications: halobutyl tire inner liner rubber, airtight rubber layers for passenger car tires, truck & engineering tire inner liner compounds, air barrier rubber hoses, sealed air storage rubber products and other high airtight rubber components.

Usage Guidance

Add nano bentonite clay together with rubber raw materials in the early stage of internal mixing.

Recommended dosage: 2wt% – 5wt%, adjust proportion according to target air tightness requirements.

Optimize rotor speed, mixing temperature and mixing time to ensure sufficient shearing for lamellar exfoliation.

Pre-drying treatment is recommended to prevent moisture from causing bubbles during vulcanization.

Carry out small batch mixing trial and air permeability testing before large-scale production.

Packing & Storage

Standard package: 25kg kraft paper bag with inner PE waterproof liner. Test samples can be provided upon request.

Keep packaging tightly sealed after opening. Store in cool, dry and ventilated warehouse. Protect from moisture and direct sunlight. Avoid heavy extrusion during transportation to prevent powder caking.
