BASF Melapur200 70 Halogen-Free Flame Retardant – Frequently Asked Questions (FAQ)

Q1: What types of polymers is Melapur200 70 compatible with?

A: Melapur200 70 is primarily designed for use in polyolefins such as polypropylene (PP) and polyethylene (PE), including both homopolymers and copolymers. It may also be incorporated into certain engineering thermoplastics where halogen-free flame retardancy is required, though compatibility and dispersion should be verified during formulation development.

Q2: How does Melapur200 70 achieve flame retardancy without halogens?

A: Melapur200 70 functions through an intumescent mechanism — upon exposure to heat, it promotes the formation of a protective, carbon-rich char layer on the polymer surface. This char insulates the underlying material, slows down heat transfer, and reduces the release of flammable volatiles, thereby suppressing flame propagation.

Q3: Does Melapur200 70 affect the mechanical properties or processability of the final compound?

A: When properly dispersed and compounded, Melapur200 70 typically delivers good balance between flame performance and mechanical integrity. It generally maintains acceptable tensile strength and impact resistance in PP-based systems. However, dosage and processing conditions — especially shear history and melt temperature — can influence viscosity and final part properties, so optimization is recommended for each application.

Q4: Is Melapur200 70 suitable for applications requiring regulatory compliance for food contact or low-smoke emissions?

A: Melapur200 70 is formulated to be halogen-free and produces significantly lower smoke and corrosive gases compared to halogenated alternatives. While it is not inherently approved for food-contact applications, its composition supports evaluation against relevant regional requirements when used in appropriate matrices and concentrations. Regulatory suitability must be confirmed case by case, considering full formulation and intended use conditions.
