IMERSHIELD P2100 was specially developed for polymer flame retardant applications. It is a Synergists for intumescent flame retardants, Intumescent flame retardants (FR) are commonly used in many engineered thermoplastics applications. It can improve FR classifications (e.g. to achieve UL94-V0 rating at 0.4 mm thickness), while synergistically enhancing the efficacy and reducing loading levels of flame retardant(s). ImerShield P2100 significantly improves the reinforcement of plastics by increasing/maintaining stiffness, strength, and impact properties. Furthermore, it allows for reducing flame retardant additive loading, improving production processing, increasing security of supply, and cost reduction. It can apply to applications such as cell phones, computers, electric vehicles, and household appliances.
