Product Description

 

Product Description

PVC is an acronym for polyvinyl chloride. A resin is a material often used in the production of plastics and rubbers. PVC resin is a white powder commonly used to produce thermoplastics.

 

Other members of the vinyl family can be used for similar applications, but PVC tends to be the most popular member of that family. It is believed to be superior to other options because it can be produced in numerous forms and used to create a wide array of items for many industries. Products made with PVC resin include blood bags, windows, and pipes.

 

Production of PVC resin generally relies heavily on the use of chlorine and crude oil. There are four manufacturing processes commonly used in its production. They are the suspension method, the mass method, the emulsion/dispersion method, and the solution method.

 

PVC resin alone is a raw material. It can be made into products with a wide range of properties from soft and flexible to light and rigid. The outcome is often determined by additives. Other ingredients must typically be added to convert this resin into a finished product. These can include heat stabilizers, lubricants, and fillers. One of the most common types of additives to be blended with PVC is plasticizers, such asbutyl glycolate, epoxy resins, and dialkyl azelates.

 

There are many benefits in plasticized PVC. Since it is a thermoplastic, meaning it can be melted down and reformed, PVC is often produced into sheets that will be reworked later. These are normally hard.

 

When plasticizers are added, the material tends to become much more flexible and pliable than it otherwise would be. The chemical resistance, stress resistance, and puncture resistance can also be increased. PVC in the plasticized form is extremely popular.

 

PVC resin generally has a high level of chemical resistance. This may not be seen, however, when the material is exposed to organic chemicals. PVC is also strong and resistant to water and abrasion. This material is very popular in the construction industry. It can be used to produce many items needed in the building process. Those items are often lightweight, long lasting and maintenance-free.

 

One weakness of PVC resin is ultraviolet exposure. The negative effects can often be reduced by additives such as plasticizers. In most cases, however, it is recommended to avoid this type of exposure.

Definition and Chemical Properties

PVC (polyvinyl chloride) is a linear polymer produced by free radical polymerization of vinyl chloride monomer. Its molecular chain contains short meso-homotetrameric structures, which give the material unique rigidity and chemical stability. According to the different content of plasticizers, PVC can be divided into three categories: rigid PVC (plasticizer ≤ 10%) is mainly used for structural components such as construction pipes; soft PVC (plasticizer > 40%) is known for its flexibility and is suitable for cable sheathing and inflatable products; semi-rigid PVC (plasticizer 10%-40%) has a balance of rigidity and toughness, and is commonly used in decorative materials and industrial labeling.

Core Physical and Chemical Properties
The physical properties of PVC are high strength, light weight (density 1.38-1.45 g/cm³) and excellent abrasion resistance, with tensile strengths up to 50-60 MPa, which makes it a good substitute for metal in construction pipe and reduces structural load-bearing pressures by up to 90%. Chemical stability is a significant advantage, the material can withstand strong acids (except concentrated sulfuric acid), strong alkalis and salt erosion, in the chemical pipeline and marine engineering life of more than 20 years. In addition, PVC has flame retardant and self-extinguishing characteristics (oxygen index ≥ 45, in line with Class B1 fire standards), combustion does not release hydrogen cyanide and other highly toxic gases, and has excellent electrical insulation (volume resistivity 10^12-15 Ω-cm), becoming the preferred material for cable sheathing.

Application Scenarios and Industry Coverage
In the construction field, PVC accounts for 60% of global consumption, and is widely used in water supply and drainage pipes, cable casings, imitation wood flooring and energy-saving door and window profiles, with its heat insulation performance increased by 50% compared with traditional materials. In the packaging industry, food-grade PVC film has become the core material for fresh packaging with an oxygen permeability of less than 0.5 cm³/m²-day. Artificial leather products have achieved 70% cost optimization in the shoe and bag sectors by imitating the texture of genuine leather. In the medical sector, PVC is certified as biocompatible and is used in medical devices such as blood bags and infusion tubes; and the automotive industry utilizes its lightweight advantages (40% weight reduction) to manufacture interior parts and seals. In industrial settings, PVC-lined chemical containers can withstand acid and alkali corrosion for more than 10 years, demonstrating their long-lasting reliability.

Environmental upgrading and technological innovation
With the increased demand for sustainable development, the PVC industry is undergoing a deep transformation towards environmental protection. The application of lead-free stabilizers (e.g. calcium-zinc system) reduces the toxicity of materials by 90%, and bio-based PVC shrinks its carbon footprint by 30% through vegetable oils and fats raw materials. In terms of technological innovation, nano-modification technology (e.g. TiO2 reinforcement) has increased tensile strength by 50%, and smart-responsive PVC has been applied to temperature-controlled building skins; high-frequency, low-loss substrates developed in the field of 5G communications can support millimeter-wave transmissions, and medical-grade antimicrobial PVC achieves an anti-bacterial rate of 99% through silver ion coating. The recycling system is becoming more and more perfect, with the physical recycling rate exceeding 80%, forming a closed-loop industrial chain from raw materials to recycling.

PVC is like an "all-rounder" in the material world - it can be transformed into a tough man with steel reinforcement, holding up the drainage spine of skyscrapers; it can also be transformed into a flexible "liquid armor", guarding the trickle of life in medical catheters. Medical catheters to guard the trickle of life. Its skeleton is made of chlorine atoms, giving it corrosion resistance comparable to that of a bulletproof vest: even if it is immersed in the acid and alkali ocean for ten years, it is still as solid as a reef; in the face of flames, it will not burn in a mess but calmly extinguish the flames (Oxygen Index ≥ 45), as if it is a miniature firefighter.

In the eyes of engineers, PVC is a "lightweight revolution" of the vanguard - less than one-fifth of the density of steel, but can carry 50 MPa tensile strength, so that the weight of the building pipeline straight down 90%, as if to the high-rise buildings wearing carbon fiber running shoes. In the electrical field, it is the silent "insulator", with up to 10 /15Ω-cm resistivity to build a current firewall, the danger is firmly sealed in the cable sheath. Even better, this chemical magician can also play with shape-shifting: by increasing or decreasing the proportion of plasticizers, it can freely switch between hard ceramic window frames and soft satin cling film, and can even be as thin as a cicada's wing (0.1mm level) but airtight, so that oxygen is in a hurry to get around outside the food packaging (oxygen permeability of <0.5cm³/m²-day).

Using the flexibility of PVC processing (supporting 12 kinds of processes such as extrusion/injection/blow molding35 ), the after-sales team can provide formula adjustment services: according to the climate characteristics of the customer's region (such as high humidity in the tropics or low temperature in the frigid zone), we can adjust the formula according to the customer's location. or low temperature in the cold zone), adjust the proportion of plasticizers for pipes or the thickness of wear-resistant layer for flooring (0.1-0.5mm precision regulation7) to achieve dynamic optimization of product performance.

3. Environmental compliance support system
For EU REACH and other regulations, based on food-grade PVC certification (FDA 21 CFR 177.260015) and heavy metal-free stabilizer technology 46, we provide a full set of test reports and certification renewal services. For example, we assist customers to pass SGS testing to ensure that the heavy metal precipitation of the drainage pipe is less than 0.01mg/L.

4. Installation and Maintenance Efficiency Improvement Program
Combining the light weight of PVC (density 1.38g/cm³) with the ease of construction (connection speed is 3 times faster than metal pipes46), we provide multi-language VR installation tutorials and intelligent diagnostic tools. By scanning the QR code on the surface of the pipe, customers can access real-time pressure test data and maintenance reminders.

5. Value-added services for circular economy
Relying on PVC's 80% physical recycling rate1, we have established cross-border recycling channels. For example, end-of-life flooring is recovered from the European market and recycled into municipal manhole covers (with a compressive strength of 50 MPa3) in Chinese factories, creating carbon credit revenue for customers. This model has enabled a German customer to reduce annual costs by 12%.
