Transparent Plastic Tables

Transparent plastic is lightweight, durable polymer materials with high light transmission, widely used in packaging, optics, and displays. Common types include PMMA (acrylic), PC (polycarbonate), and PET, offering clarity, impact resistance, and versatility. They replace glass in many applications due to their shatterproof nature, cost-effectiveness, and ease of molding.

Transparent Plastic Tables

Type Chemical Name Properties Common Applications Advantages Disadvantages
PMMA Polymethyl Methacrylate (Acrylic) High transparency (92% light transmission), good weather resistance, easy to process, moderate impact resistance Signage, car windows, optical lenses, display stands High clarity, UV-resistant, easy to mold Prone to scratching, low heat resistance (~80℃)
PC Polycarbonate High strength, heat-resistant (~120℃), excellent impact resistance, slightly lower transparency than PMMA (88-90%) Bulletproof glass, eyewear lenses, medical devices, helmet visors High heat/impact resistance Expensive, prone to stress cracking
PS Polystyrene High transparency (regular PS is brittle), low cost, easy to process Food packaging, disposable utensils, CD cases Low cost, easy to injection mold Brittle, poor chemical resistance
PET Polyethylene Terephthalate High transparency (can crystallize in fibrous form), good chemical resistance, mechanical strength Beverage bottles, food containers, films Recyclable, chemical corrosion-resistant Deforms at high temps (~70℃)
PVC Polyvinyl Chloride (Rigid) Adjustable transparency (requires additives), flame-retardant, chemical-resistant Packaging films, credit cards, pipes Low cost, flame-resistant May contain non-eco-friendly plasticizers
SAN Styrene-Acrylonitrile Copolymer High transparency, better chemical resistance than PS, high hardness Kitchenware, cosmetic bottles, instrument housings Good chemical/mechanical resistance Moderate weather resistance
COC Cyclic Olefin Copolymer Extremely high transparency (92%), low birefringence, high rigidity Optical components, medical packaging, display films Excellent optical properties, low moisture absorption Expensive

Additional Notes:

  • Eco-Friendliness: PET is the most recyclable; PVC may contain chlorine additives and requires careful handling.

  • Heat Resistance: PC > PMMA > PET > PS; PC is preferred for high-temperature environments.

  • Cost: PS/PET are the cheapest; COC/PMMA are more expensive; PC is mid-range.
