Technical details and manufacturing context for Elastomer Emulsion

Definition

Elastomer emulsion is a water-based colloidal system where elastomeric polymer particles (typically in the size range of 50-500 nm) are uniformly dispersed in an aqueous continuous phase. These emulsions are stabilized by surfactants or protective colloids to prevent particle aggregation and maintain long-term stability. They are characterized by their ability to form flexible, rubbery films upon drying while being processed and applied in water-based systems. This product type is used in the rubber and plastic product manufacturing industry as a material input. The emulsion typically contains synthetic elastomers such as styrene-butadiene rubber (SBR), nitrile rubber (NBR), or chloroprene rubber (CR), as well as natural rubber latex, water, and surfactants or emulsifiers. Key parameters include total solids content (50-60% by weight, ISO 1625), pH value (7.0-9.0, ISO 976), viscosity (100-500 mPa·s, ISO 2555), particle size (0.1-0.5 nm, ISO 13321), glass transition temperature (-20 to 10 °C, ISO 11357-2), density (0.95-1.05 g/cm³, ISO 2811-1), minimum film formation temperature (5-15 °C, ISO 2115), mechanical stability (≥300 s, ISO 2555), storage stability (6-12 months, ISO 1625), ionic charge (anionic), VOC content (≤50 g/L, ISO 11890-2), tensile strength (5-15 MPa, ISO 37), and elongation at break (300-600%, ISO 37). These values are reference ranges and must be verified for the specific product model or application with the legal manufacturer or supplier. The emulsion is designed for use in water-based systems where it forms a flexible film upon drying. It is important to avoid freezing and keep the container sealed to maintain stability. Compatibility with additives should be checked, and regulatory compliance regarding VOC content must be confirmed. This directory entry is for reference only and does not imply certification or compliance of any specific product.

Working Principle

Elastomer emulsions function through emulsion polymerization where monomers are polymerized in water using surfactants to form stable polymer particles. When applied to a substrate and dried, the water evaporates, causing the polymer particles to coalesce and form a continuous elastomeric film. The surfactants facilitate particle dispersion during storage and application, while the elastomeric nature of the polymer provides flexibility, elasticity, and resilience in the final film. The process requires careful control of parameters such as solids content, pH, and viscosity to ensure proper film formation and performance. The minimum film formation temperature indicates the lowest temperature at which a continuous film can form without cracking. Mechanical stability refers to the resistance to coagulation under shear, which is important during pumping and mixing. Storage stability indicates the shelf life under recommended conditions. The ionic charge (anionic) affects compatibility with other additives. The final film properties, such as tensile strength and elongation at break, depend on the polymer type and formulation. Verification of these parameters with the manufacturer is essential for specific applications.

Frequently Asked Questions

What is the typical particle size range for elastomer emulsions?

According to the reference data, the average particle size is typically in the range of 0.1 to 0.5 nm (as per ISO 13321). However, the source facts also mention a general size range of 50-500 nm for the polymer particles. These values should be verified with the manufacturer for the specific product.

How should elastomer emulsions be stored?

Storage stability is listed as 6-12 months under ISO 1625. It is recommended to avoid freezing and keep the container sealed to prevent evaporation and contamination. Always follow the manufacturer's storage instructions for the specific product.

What is the minimum film formation temperature (MFFT) and why is it important?

The MFFT is the lowest temperature at which the emulsion will form a continuous film upon drying without cracking. For this product type, the reference range is 5-15 °C (ISO 2115). It is important because applying the emulsion below this temperature can result in film defects. Verify the exact MFFT for your application with the supplier.

Are elastomer emulsions environmentally friendly?

Elastomer emulsions are water-based, which generally reduces VOC emissions compared to solvent-based systems. The VOC content is listed as ≤50 g/L (ISO 11890-2). However, regulatory compliance must be confirmed with the manufacturer, as specific formulations may vary.
