Scorch prevention

NOFMER® MSD

NOFMER® MSD is a suitable Chain Transfer Agent (CTA) for polymers containing styrene such as PS, AS polymers or SB latexes. In addition, NOFMER®MSD can be used as an addition agent with functions of a crosslinking co-agent and a retarder for LDPE crosslinking.

Because of these features, NOFMER®MSD is used in the production of coating materials, high–voltage electric cables and others.

Feature of NOFMER®MSD

It works as a chain transfer agent (CTA) for PS, ASpolymers or SB latexes, etc.

It works as a crosslinking co-agent and a retarder for LDPEcrosslinking (XLPE)

It has less odor compared tomercaptans or other retarders (BHT etc).

Application

NOFMER® MSD is used in the production of coating materials as a CTA or covering of high–voltage electric cables as a crosslinking co-agent and a retarder.

Technical Data

NOFMER® MSD can prevent scorch effectively as a retarder at kneading temperature (145˚C). NOFMER® MSD has well balanced results in both torque value and scorch time.
