Modified Plastics

Modified plastics refer to a series of plastic materials whose certain properties are purpose‑improved through physical or chemical methods based on general‑purpose plastics and engineering plastics. The core idea is to make up for shortcomings and enhance advantages of ordinary plastics by adding additives or blending with other materials, so as to meet strict requirements from various industries.

Main Categories of Modified Plastics

Ⅰ. Reinforced Modified Plastics By incorporating high‑strength materials such as glass fiber and carbon fiber into resin matrices (e.g. PP, PA, PC), their mechanical strength, rigidity and heat resistance are significantly improved. Typical applications include automotive inner door panels and engine peripheral parts, which replace metals for lightweight purposes with high strength and rigidity; aerospace components such as aircraft fuselage and propellers pursuing superior specific strength and specific modulus; as well as high‑load mechanical parts including bearings, gears and pump impellers.

Ⅱ. Filled & Toughened Modified Plastics Filling modification adds mineral fillers such as calcium carbonate and talcum powder into plastics, mainly for higher hardness, optimized shrinkage performance and cost reduction. Toughening modification improves impact toughness, especially low‑temperature toughness, by adding toughening agents. They are widely adopted for home‑appliance bases and housings such as refrigerator door panels to balance performance and cost, as well as consumer goods including toy shells and plastic luggage.

Ⅲ. Flame‑Retardant Modified Plastics Flame‑retardants are blended into resins to make originally combustible plastics (e.g. PP, ABS) self‑extinguishing upon fire removal and meet safety standards such as V‑0 rating. They are widely used in fire‑safety‑critical fields: switches, sockets, circuit breakers, charger housings and TV‑set casings in electrical & electronics industry; battery‑module housings, charging‑pile and charging‑gun housings for new‑energy vehicles as the first line of electrical‑safety protection; and automotive interior parts such as instrument panels to reduce fire hazards.

Ⅳ. Plastic Alloys New materials with complementary or synergistic properties are produced by physically blending or chemically grafting two or more incompatible polymers. The most typical example is PC/ABS alloy, which combines heat resistance and mechanical performance of PC with processing flowability of ABS. It is extensively used for automotive instrument panels, interior trims and housings of electronic devices such as laptops and mobile phones.

Ⅴ. Functional Modified Plastics Besides the above categories, modified plastics are developed for special demands: weather‑resistant modification (e.g. PET for photovoltaic backsheets resisting UV radiation and acid rain), antibacterial modification (for medical‑device housings and disposable syringes), degradable modification (additives blended into bioplastics such as PLA for express‑delivery packaging and agricultural films balancing environmental‑friendliness and practicality), and antistatic / conductive modification (for precision instruments and electronic equipment).
