1. PE board: polyethylene board. PE sheet is a highly crystalline, non-polar thermoplastic resin. The original HDPE is milky white in appearance and is translucent to a certain extent in the thin cross-section. PVC board: Polyvinyl chloride (PVC) plastic is a polymer made from free radical polymerization of vinyl chloride monomers. The English name is polyvinyl chloride, or PVC for short. PVC board is a board made of PVC with a honeycomb mesh structure in cross-section.
2. It is widely used as structural polymer materials and is widely used as special engineering plastics after filling and modification.
3. The biggest difference between nylon board and PE board is that in high temperature environments, nylon's high temperature resistance is about 110, while PE's high temperature resistance is about 90. However, in room temperature environments, PE's wear resistance is higher than nylon. 3-5 times.
What is the difference between PP,PVC,PC,PS,ABS plastic raw materials?
Polyethylene (PE): PE is divided into low pressure polyethylene (HDPE) and high pressure polyethylene (LDPE). HDPE has better thermal, electrical and mechanical properties, while LDPE and LLDPE (linear low pressure polyethylene) are more flexible and have good impact properties and film forming properties. LDPE and LLDPE are mainly used for packaging films, agricultural films and plastic modification, while HDPE is widely used in films, pipes and injection daily necessities.
In addition, for example, PE and PP have dripping, while PVC, etc., have no dripping, but have self-extinguishing. Optical method: mainly examines the transparency of raw materials. Generally used transparent raw materials are: PS, PC, PMMA, AS; translucent raw materials are: PE, random copolymer PP, homopolyPP, soft PVC, transparent ABS, etc., other raw materials are basically opaque.
Among plastic toy materials such as ABS, PVC, PP, PC, and PE, ABS and PP are better and relatively safe, while PVC and PC materials may be harmful under certain conditions. ABS material: ABS is a composite of three substances: acrylonitrile, butadiene, and styrene. It has the characteristics of high hardness and toughness, good size stability, high temperature resistance, low temperature resistance, drop resistance, and non-toxicity.
PP==== Baifold glue, polypropylene, light and tough, easy to process, good heat resistance,. High impact strength at room temperature, high tensile strength, good rigidity, corrosion, difficulty in painting, folding resistance up to millions of times, excellent electrical properties, and large shrinkage.
Burning characteristics of ABS plastic raw materials: Yellow flame, black smoke and water droplets are produced during combustion. Accompanied by sour taste and rubber burning smell, the flame spreads slowly. Physical properties: Opaque hard material, specific gravity 04 (slightly heavier than water), prone to stress cracking (when exposed to acid or organic solvents). Solubility: Easily soluble in acetone, dichloroethane, tribromomethane. Typical uses: Toy shells, non-stress parts for daily necessities.
Plastics are classified in various ways, mainly based on the molecular structure, application scope and synthetic resin identification code (recycling mark). Common types such as ABS, PA, PP, and PET are distinguished as follows: Classification of thermoplastics by molecular structure: Repeated heating still has plasticity. Common raw materials include PE, PP, PVC, PS, ABS, PMMA, POM, PC, PA, etc.
What are the common choices for organ board materials?
1. Common materials for organ boards include PVC, polypropylene (PP), aluminum alloy, polycarbonate (PC) and glass fiber reinforced plastic (FRP). PVC material is low in cost, light in weight and waterproof. It is suitable for temporary partitions or humid environments. However, it has poor weather resistance and is prone to aging and discoloring in long-term sun exposure. Polypropylene (PP) is more resistant to high temperatures (80-100℃) than PVC and has strong chemical corrosion resistance. It is common in laboratories or industrial workshops, but may become brittle in low temperatures.
2. Materials commonly used to make organ boards include metal, plastic, wood and composite materials, and the specific choice depends on the application scenario and performance requirements. Metal materials Aluminum plates and steel plates are the most common metal organ plate materials. Aluminum is light and corrosion-resistant, making it suitable for outdoor buildings and transportation; steel plates have high strength and are mostly used for industrial equipment protection. Stainless steel is commonly used in food processing or humid environments due to its rust-proof properties.
3. Organ boards are usually made of plastic materials such as polypropylene (PP), polyvinyl chloride (PVC), and polyethylene (PE). Some high-end products use aluminum alloys or composite materials. The plastic material polypropylene (PP) is the most common choice. It has the advantages of corrosion resistance, light weight and low cost. It is suitable for outdoor billboards, temporary partitions and other scenes. Polyvinyl chloride (PVC) is harder and is commonly used in industrial protective covers or building expansion joint covers.
4. Common material type polypropylene (PP): light, corrosion resistant, low cost, suitable for ordinary organ protective covers. Polyethylene (PE): It has good flexibility and is mostly used for occasions that require frequent folding. Polyvinyl chloride (PVC): Wear resistant and flame retardant, commonly found in industrial-grade organ rail covers.
5. The material characteristics and requirements of organ boards mainly focus on three aspects: durability, flexibility and environmental adaptability. Durability organ boards need to withstand frequent folding and unfolding, so the material must have high fatigue resistance and wear resistance. Common durable materials include polypropylene (PP), polyvinyl chloride (PVC) and glass fiber reinforced plastic (FRP), which effectively resist tearing and wear caused by long-term use.
