Elastomer Polymer Particles: Particle Size 0.1-1 μm, Solids Content 40-60%

Component Specifications

Definition

Elastomer polymer particles are the dispersed phase in an elastomer emulsion. They are typically made from monomers such as butadiene and styrene by emulsion polymerisation, with particle sizes between 0.1 and 1 μm, and they give the finished product its elasticity, abrasion resistance and tear strength.

Working Principle

In emulsion polymerisation the monomers are dispersed in water; under the action of a surfactant and an initiator they form stable polymer particles, which coalesce into an elastomer once dried.

Materials

Monomers such as butadiene, styrene and acrylonitrile; a surfactant (e.g. sodium dodecyl sulfate); an initiator (e.g. potassium persulfate); and water.

Frequently Asked Questions

How does particle size affect the performance of elastomer polymer particles?

A smaller particle size increases the specific surface area, which raises crosslink density and strength, but can reduce flow during processing.

How should elastomer polymer particles be stored?

Store them in a cool, dry place out of direct sunlight, below 30 °C and below 60 % relative humidity.
