The functions of several materials in the LED lampshade

1. The functions of several materials in the LED lampshade are as follows. Polycarbonate (PC): LED lampshades made of PC have good light transmittance and strong drop resistance ability. They can effectively protect LED lights. They have good plasticity, low cost and easy manufacture. Polyethylene (PE): LED lampshades made of PE have good corrosion resistance and long service life, but poor light transmission.

2. There are two main materials for LED lampshades: plastic and glass. The following is the breadth of plastic materials of these two materials: Plastic LED lampshades are widely used in various lamps due to their low manufacturing costs, light weight and ease of processing. Category: Plastic lampshades are mostly made of PC material because they have high light transmittance, impact resistance and heat resistance.

3. There are mainly the following materials for LED lampshades: Glass lampshades are widely used in LED lamps. Glass material has good light transmission, heat resistance and chemical stability. It can effectively protect LED chips while allowing light to be evenly distributed. In addition, glass lampshades are easy to clean, resistant to high temperatures and have a long service life. Acrylic material Acrylic is a plastic material, and the LED lampshades made of it are also widely used.

The difference between pe lampshade and pc lampshade

1. Production materials: PE lampshade is made of polyethylene (PE) as the main raw material, while PC lampshade is made of polycarbonate (PC) material. The physical and chemical properties of these two materials are different, resulting in different performance and performance of the lampshade. Transparency: The transparency of PC materials is very high, allowing the PC lampshade to provide higher light transmittance and make the light brighter.

2. First of all, PE lampshades and PC lampshades are different in quality. PC lampshades use polycarbonate, which is widely regarded as a high-quality material because it is very strong and durable and can withstand high temperatures. In contrast, PE lampshades are made of polyethylene, which is relatively fragile and difficult to withstand high temperatures and high pressures. Secondly, PE lampshades and PC lampshades are also different in transparency.

3. Different production materials and different environmental properties of materials. Different materials: PC lampshades are made of PC (polycarbonate). The pe lampshade is made of silica gel as the main raw material. The environmental properties of materials are different: PC lampshades are just ordinary plastic. PE lampshades are environmentally friendly plastic.

4. The functions of several materials in the LED lampshade are as follows. Polycarbonate (PC): LED lampshades made of PC have good light transmittance and strong drop resistance ability. They can effectively protect LED lights. They have good plasticity, low cost and easy manufacture. Polyethylene (PE): LED lampshades made of PE have good corrosion resistance and long service life, but poor light transmission.

Rankings of the best plastic raw materials

1. Universal plastic raw material polyethylene (PE): divided into LDPE, HDPE, and LLDPE. It is resistant to chemical corrosion and has good electrical insulation properties. It is suitable for packaging films, agricultural films, and pipes; polypropylene (PP) has low density and high temperature resistance and is used for plastic containers, automobile parts; polyvinyl chloride (PVC) hard version is suitable for water pipes/profiles, and soft version is used for plastic sheets/floor mats; Polystyrene (PS) has high transparency and is mostly used for food packaging boxes and toy shells.

2. The plastic raw materials currently selling well on the market mainly include the following: ABS: ABS is a thermoplastic with good comprehensive properties. It has the characteristics of excellent processing properties, good surface gloss, easy coloring, etc., and is widely used in automobiles, electronic appliances, building materials and other fields. PC: PC has the characteristics of high strength, high transparency, and high impact resistance. It is an ideal material for manufacturing optical discs, eyeglass lenses, water bottles, bulletproof glass and other products.

3. Covestro is a leading global manufacturer of polymer materials. Its plastic materials are widely used in many fields such as construction, automobiles, furniture and consumer electronics. The brand's plastic materials are known for their excellent performance and reliability. BASF BASF is one of the world's largest chemical companies, and its plastics business covers a variety of materials, including engineering plastics, polyurethane and plastic additives.

4. Universal plastic polypropylene (PP): It is one of the basic raw materials for the largest injection molding of luggage. It has a density of about 0.9 g/cm, has good toughness, strong bending fatigue resistance, short forming cycle, low processing energy consumption, and the cost is only About 60% of ABS. It is mostly used to produce structural parts such as boxes, tie rod bases, and lining support plates for mass-priced travel cases. The disadvantage is that it has poor ultraviolet aging resistance and is prone to embrittlement and yellowing due to long-term outdoor exposure.

5. Price comparison and industry status The most expensive candidate: Kevlar/Nomex fiber: Due to the complex fiber production process and irreplaceable performance, the price per unit weight may be higher than that of other plastics. PEEK/PEKK: Medical-grade brands can be more than 10 times that of ordinary engineering plastics due to their high certification cost. PAI: The performance is close to that of metals, and the price often competes with high-end alloys.

Plastic material competition

1. Chemical resistance: PTFE, PP and PVDF perform excellent in chemical corrosion resistance. Low cost: PE, PP and PVC are lower-cost plastic materials. Transparency: If transparent materials are needed, PC, PMMA and PS are good choices. Wear resistance: POM, PA66 and UHMW-PE are outstanding in terms of wear resistance. To sum up, different plastic materials each have their own unique advantages and disadvantages, as well as typical applications that are suitable. When selecting, the above factors need to be comprehensively considered according to the specific use environment and requirements to find the most suitable plastic material.

2. Material characteristics: TPO is a blend of rubber and polyolefin with certain durability.

3. From a safety perspective, PCTG and PPSU bottles do not contain harmful substances such as bisphenol A and phthalates, and both meet safety standards. However, PPSU meets medical grade standards and is safe under long-term use and high temperature disinfection scenarios. More prominent.

4. The materials of plastic bottles are mainly PP (polypropylene), PPSU (polyphenylsulfone) and PES (polyethersulfone resin), and there are also a small amount of PA (polyamide) material transparency and wear resistance: PPSU and PA are the best High temperature resistance Performance: Both can withstand high temperatures above 100 ° C (PP bottles generally withstand high temperatures of 120 ° C, PPSU bottles can withstand high temperatures of 180 ° C, PES bottles can also withstand high temperatures of 180 ° C, and PA bottles can withstand high temperatures of 220 ° C.
