Organo Modified Montmorillonite Nanoclay CAS 1318-93-0 Improve Barrier Property for Polymer Composite
Organo Modified Montmorillonite Nanoclay CAS 1318-93-0 is organophilic layered silicate nanofiller modified by organic cation exchange.
Surface organic modification changes hydrophilic natural montmorillonite into organophilic nanoclay, enabling uniform exfoliation and dispersion in various polymer substrates. The staggered lamellar structure forms tortuous diffusion channels, which effectively slow down the penetration of gas and water vapor. It significantly improves barrier property, thermal

Product Overview
Organo Modified Montmorillonite Nanoclay CAS 1318-93-0 is organophilic layered silicate nanofiller manufactured via organic cation exchange modification of natural montmorillonite.Raw sodium montmorillonite is hydrophilic and poorly compatible with organic polymers. After surface organic modification, the nanoclay turns organophilic and can be exfoliated into ultra-thin single or few-layer nanosheets inside polymer matrix. The dispersed lamellae build tortuous penetration paths to block gas and water vapor transmission. Besides outstanding barrier performance, this product also elevates tensile strength, heat distortion temperature and dimensional stability. It serves as a cost-effective functional nanofiller for diversified polymer composite systems.
Product Properties
The product is fine off-white powder with layered nanostructure. Good lipophilicity ensures favorable compatibility with thermoplastics, thermosets, rubber and solvent-based resins. It can achieve nanoscale exfoliation under proper shearing conditions. Low heavy metal and impurity content meets general industrial composite requirements. Excellent thermal resistance adapts to conventional polymer processing temperature range. The lamellar structure maintains stable barrier effect after molding.
Core Advantages
Organophilic surface treatment. Solve incompatibility issue between raw clay and organic polymer.Remarkable barrier improvement. Reduce permeability of oxygen, carbon dioxide and water vapor effectively.Nanoscale exfoliation. Form staggered lamellar network without large agglomerates.Multi-performance enhancement. Boost mechanical strength, thermal stability and anti-creep property simultaneously.Wide formulation adaptability. Suitable for extrusion, injection, coating and calendering processes.Economical dosage. Reach target barrier indicators with low addition amount to control production costs.
Main Applications
Organo Modified Montmorillonite Nanoclay is widely applied as functional filler for polymer composites. Typical applications: food & industrial packaging barrier films, PA/PP barrier plastic containers, anti-corrosion barrier coatings, rubber sealing materials, epoxy composites, biodegradable plastic products and flame retardant polymer materials.
Usage Guidance
Carry out sufficient high-speed shearing or twin-screw melt compounding to realize lamellar exfoliation.Adjust adding dosage ranging from 1wt% to 5wt% according to required barrier level.Match suitable compatibilizer for non-polar polymer to promote uniform dispersion.Complete small-scale formulation trial and barrier performance testing before mass production.Prevent moisture absorption during storage; dry processing is recommended for high-barrier requirements.
Packing & Storage
Standard package: 25kg kraft paper bag with inner PE liner. Samples are available upon request.Seal packaging tightly after use. Store in cool, dry and ventilated warehouse. Keep away from moisture and direct sunlight. Avoid heavy extrusion during transportation to prevent powder agglomeration.
