Selecting Plasticizers for Adhesives and Sealants
Plasticizers are used in all types of adhesive and sealant formulations. They are used primarily to the final bond and to provide improved low-temperature properties. However, plasticizers can also supply additional benefits that are important to both the formulator and end-user.

KURARAY LIQUID RUBBER - Elastomer Division | Specialty Chemicals
The high-viscosity synthetic rubbers are colorless, transparent, almost completely odorless and have low VOC values. The polymers of butadiene, isoprene and styrene have a low molecular weight, which is designed between solid rubber and plasticizer. KURARAY LIQUID RUBBER grades are co-vulcanizable with the base rubber to prevent migration.
Plasticizer
A plasticizer ( UK: plasticiser) is a substance that is added to a material to make it softer and more flexible, to increase its plasticity, to decrease its viscosity, and/or to decrease friction during its handling in manufacture. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the
- What is the value of the rubber additives market?
- The global rubber additives market was valued at USD 7.90 billion in 2021 and is expected to grow at a CAGR of 3.6% during the forecast period. They are added to rubber compounds to acquire superior properties.
- How can plasticizers be used to make polymers soft and flexible?
- By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature. Plasticizers are classified according to their molecular structure into monomeric or polymeric types.
- How are plasticizers classified?
- Plasticizers are classified according to their molecular structure into monomeric or polymeric types. The choice of the plasticizer is dependent on the requirements that have to be met for the final product and the conditions around that product’s use.
- How do plasticizers affect polymers?
- Plasticizers are substances which, by virtue of their polar or polarizable structure, weaken the secondary valence forces of polymers. By adding plasticizers to compatible polymers, the materials can be modified in such a way that they become soft and flexible by decreasing their glass transition temperature.
- How to choose a plasticizer?
- The choice of the plasticizer is dependent on the requirements that have to be met for the final product and the conditions around that product’s use. This may include low volatility, high permanence, low temperature flexibility, flame retardancy, high thermal stability and saponification resistance.
