Softening Masterbatch

Softening masterbatches are additives used in polymer processing to improve the flexibility, pliability, and overall “softness” of a plastic material. They achieve this by reducing the polymer’s glass transition temperature (Tg) or by introducing internal plasticization.

Description

Olefinic Softening Masterbatches (for Polyolefins like PE, PP)
- Ethylene Vinyl Acetate (EVA) Masterbatches
  This is one of the most common and versatile types. EVA copolymers are inherently flexible and act as internal plasticizers for polyolefins.

Ester-Based Softening Masterbatches (for PVC and other polar polymers)
- Phthalate Ester Masterbatches
  Historically, these were very common. However, due to health and environmental concerns, their use is now restricted in many regions.
Silicone-Based Softening Masterbatches
- Silicone Oil/Elastomer Masterbatches
  Silicones are known for their unique tactile properties and lubrication.
- How it works? Silicone oils can migrate to the surface, providing a smooth, soft feel. Silicone elastomers can be incorporated to improve flexibility and impact strength.
Other Specialty Softening Masterbatches
- Mineral Oil/Paraffin Oil Masterbatches
  Used in certain applications, particularly in rubber compounding or for specific aesthetic effects.
