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.
