Red Phosphorus Flame Retardant Master Batch

  • Microencapsulated Red Phosphorus
  • Red Phosphorus Flame Retardant Master Batch

Red phosphorus is an outstanding flame retardant, featuring an excellent heat stability and a high fire retardation efficiency. Because traditional red phosphorous easily absorbs moisture and has a poor compatibility with a high polymer material, Yinsu utilizes microencapsulated red phosphorous flame retardant powder. By encapsulating it in an organic resin, the compatibility between the red phosphorus and organic resin is improved, and the thermal stability, moisture absorption and resistance to migration of the flame retardant are greatly improved. The microencapsulated red phosphorus features a higher fineness, uniform grain size and excellent dispersion. When used in plastic products, their physical performance won't be influenced. The microencapsulated red phosphorus flame retardant is provided with dust free particles, allowing for higher safety during transportation, storage and application.

Backed by more than 20 years of experience in the development of red phosphorous flame retardant, we will change the formula according to customer requirements. For more information, please do not hesitate to contact us, as we guarantee we will do everything possible to meet each of your requirements for flame retardant materials.

Our products of this series include FRP-950, FRP-750, FRP-301, P850, and PET-501.

Features
High efficiency

Due to the high content of red phosphorus, high flame retardancy can be achieved by adding a small amount.

Good mechanical property

Due to the low dosage needed to achieve UL-94 V0 class (approx.5.6-7.2% by weight as pure red phosphorus), they show low impact on mechanical properties.

Small grain size

The red phosphorus grain size of theFRP-950 series flame retardant is over 1000 mesh, while the grain size of red phosphorus in the market is normally 100-200 mesh.

Halogen free and environmentally friendly

The microencapsulated red phosphorus flame retardant passes SGS tests and meets RoHS requirements.

Good stability

Compared to a normal red phosphorus fire retardant, the microencapsulated red phosphorus fire retardant features a superior chemical stability.

Superior electrical property

The Fe in the raw material for red phosphorus is effectively removed during production, ensuring the CTI value (comparative tracking index) is effectively increased. Thus, microencapsulated red phosphorus fire retardant is useful for electronic industries.

Package storage and transportation
