Synthetic Resins Technology Handbook

Various thermoplastic thermosetting polymers, including elastomers, have been incorporated to modify the properties for the cured epoxy resin products. Elastomers provide greater elongation and impact strength. Polysulfides, the most commonly used elastomer to flexibilise epoxy resins.

Plastics, a class of polymer materials synthesized from monomers, are widely used in industries, agriculture, healthcare, and daily life due to their lightweight, durability, and malleability. with technological advancements and societal evolution, demands for higher performance of plastic products have escalated. Traditional, unmodified plastics can no longer meet the diverse needs of modern applications. Consequently, research on plastic modification has become critical to enhancing their properties.

Plastic modification refers to altering the fundamental properties of plastics through physical or chemical methods to suit specific usage environments and requirements. Common modification techniques include filler modification, blend modification, graft modification, toughness modification, and reinforcement modification. Each method has unique advantages and can be selected based on practical application needs.

Filler Modification involves incorporating inorganic or organic fillers—such as glass fibers, carbon fibers, mica powder, or talc powder—into the plastic matrix to improve mechanical strength and heat resistance. For example, adding glass fibers significantly enhances tensile and flexural strength, while mica powder reduces the coefficient of thermal expansion, improving heat resistance.

Blend Modification combines two or more plastics through molecular interactions to optimize mechanical properties, heat resistance, chemical resistance, and processability. A notable example is blending polyamide (PA) with polycarbonate (PC) to create poly(amide-imide), an engineering plastic with exceptional comprehensive performance.

Graft Modification chemically bonds functional monomers onto plastic polymer chains, imparting new properties. For instance, grafting maleic anhydride onto polyethylene produces a copolymer with enhanced toughness and UV resistance.

Toughness Modification introduces elastomers or rubber particles to increase plastic flexibility, preventing brittle fracture under stress. Adding natural rubber particles to polypropylene (PP) yields modified PP with high impact strength and improved toughness.

Reinforcement Modification enhances plastic strength and rigidity through physical or chemical means. Incorporating nano-scale fillers like nano-calcium carbonate or nano-silica produces high-strength, high-rigidity composites.

The application prospects of plastic modification are vast. Advances in material science have introduced novel modifiers, such as functionalized fillers, bio-based fillers, and eco-friendly additives, expanding modification possibilities. Frontier technologies like nanotechnology, surface treatment, and green chemistry further support innovation in plastic modification.

challenges remain. Achieving low-cost, high-efficiency modification is urgent. Ensuring stable performance and environmental friendliness of modified plastics is key to sustainable development. Additionally, improving safety and eco-compatibility during modification processes demands attention.

modifying synthetic resins is vital to advancing plastic performance. By leveraging various modification techniques, high-performance plastics tailored to industrial and everyday needs can be developed. Looking ahead, ongoing technological and societal progress will drive continuous innovation in plastic modification, contributing significantly to human development.
