Samsung patents flame-retardant plastic mix for safer electronics

Patent drawing from the official filing.

Samsung has been granted a patent for a specific plastic recipe that resists catching fire. The material combines polypropylene resin with magnesium hydroxide, melamine-based resin, talc, rubber, and a coupling agent in precise amounts. This mixture is designed to maintain strong tensile and impact resistance while preventing flames.

Why it mattersThis filing details a standard industrial method for making plastics safer, which is a routine improvement for manufacturers looking to meet safety standards without sacrificing durability.

In the filing’s own words

A flame-retardant plastic material composition including polypropylene resin, magnesium hydroxide, melamine-based resin, talc, rubber, and coupling agent, where the flame-retardant plastic material composition includes 30 to 45 parts by weight (wt %) of the magnesium hydroxide and 8 to 20 parts by weight (wt %) of the talc based on 100 parts by weight (wt %) of flame-retardant plastic material composition, and a tensile strength is from 130 to 600 kgf/cm 2.

What exactly they claim (claim 1)

1. A flame-retardant plastic material composition, comprising: polypropylene resin, magnesium hydroxide, melamine-based resin, talc, rubber, and coupling agent, wherein the flame-retardant plastic material composition includes: 30 to 45 parts by weight (wt %) of the magnesium hydroxide, and 8 to 20 parts by weight (wt %) of the talc based on 100 parts by weight (wt %) of the flame-retardant plastic material composition, wherein a tensile strength of the flame-retardant plastic material composition is from 130 to 600 kgf/cm 2, and wherein an impact strength of the flame-retardant plastic material composition is from 6 to 50 kgf·cm/cm.
