CEREPLAS™ OTM STI (Stabilised)

Product information

Product Name
CEREPLAS™ OTM STI (Stabilised)
Description

CEREPLAS™ OTM STI is produced by the controlled esterification of trimellitic anhydride and 2-ethylhexanol. It is a clear, virtually colorless and almost odorless liquid, miscible with inert organic solvents but immiscible with water.

CEREPLAS™ OTM STI is a stabilized version of CEREPLAS™ OTM. Stabilizer is added to prevent the oxidative degradation of rubber and plastics that causes a loss of strength and flexibility in these materials.

CEREPLAS™ OTM STI is designed for use in flexible PVC applications where low volatility and resistance to high temperature environments is required, typically in high temperature cables. The low rates of migration of CEREPLAS™ OTM STI from PVC ensures long service life and is strongly recommended for low “fogging” applications such as automotive internal trim.


Benefits

• Enhanced oxidation resistance compared to OTM

• High thermal resistance

• Low migration rate

• Low fogging

• Good replacement to phthalates
