POLYFUL’s modified engineering plastics are modified materials built upon general-purpose plastics and engineering plastics by adding proper performance additives, thus improving their mechanical properties and flame retardant grade and other related performance indexes. The modified plastics has strength similar to steel, as well as the advantages of low density, high toughness, corrosion resistance, high impact resistance, wear and shock resistance, flame retardant, and ageing resistance, which can be widely used in many fields such as automobile manufacturing, household appliances, rail transportation, construction consumables, etc.
