Plasticizers

Plasticizers are organic chemical additives that improve the flexibility, softness, and processability of rubber and polymers.

Enhancing Flexibility & Performance

Plasticizers are organic chemical additives that improve the flexibility, softness, and processability of rubber and polymers. They are widely used in tires, conveyor belts, and footwear, offering improved performance across various environmental conditions.

How Plasticizers Work

  • Processing Aid – Reduces viscosity for easier mixing and molding
  • Flexibility Enhancer – Maintains elasticity at low temperatures
  • Adhesion Booster – Improves rubber’s ability to bond with surfaces
  • Performance Improver – Enhances durability across temperature extremes

Types of Plasticizers

Phthalates

A common plasticizer that improves flexibility and durability, but some can have negative health effects.

Adipates, Citrates & Phosphates

Safer alternatives to phthalates that are becoming more popular.

Diisononyl Phthalate (DINP)

A less volatile plasticizer that provides durability and flexibility at high and low temperatures.

Considerations when using plasticizers

Plasticizers optimize rubber’s flexibility, durability, and adhesion, making them crucial in industrial and consumer applications. But there are some facts to take into consideration before their use.

  • The amount and type of plasticizer used can affect the rubber's mechanical properties.
  • Plasticizers can sometimes migrate out of the rubber, causing stains.
  • The selection of plasticizer should be carefully considered for the specific application and desired properties of the final product.
