Applications

MCCPs, used as flame retardants and plasticizers in flexible plastics, rubbers, and other polymers, have a wide range of applications. Most MCCPs are adopted in the production of PVC products while the remaining are used to produce rubber or other polymer products. In electrical and electronic products, MCCPs are mainly used to produce PVC insulated cables or wires, flexible plastics, or rubber parts, including polyurethane, vulcanized rubber, acrylic acid, and butyl sealant.

TBBP-A is mainly used as the predictor for the production of brominated epoxy resins, and in the production of FR4 type printed wired boards (FR4 PWB) functioning as the reactive flame retardant. It can also be used in epoxy sealants, adhesives, and packaging. Moreover, TBBP-A is used as the additive flame retardant in thermoplastic electrical and electronic components. For example, the housings of the ABS plastic.

Restrictions

The regulated limit is suggested as 0.1% (mass fraction).
