Product Overview
HCPE is a type of Chlorinated Polymer which contains chlorine at 65-69%. It is transparent, hard and brittle thermoplastic resins. It has high chemical stability, good salt water resistance and good ultraviolet resistance. It is readily soluble in organic solvents such as toluene, xylene and esters, forming a colorless to pale yellow, transparent solution. When this solution is applied to the surface of metal, concrete, paper etc., the solvent readily vaporizes at room temperature to leave a transparent, hard and lustrous glass-like film. This film resists the permeation of moisture and oxygen gas, and shows high resistance to various chemicals such as acids and alkalis. It protects the substrates from corrosion, and also serves as a top coating for decorative purposes.

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).
Packaging & Shipping
After Sales Service
1. Globalized spare parts supply network
Relying on the core characteristics of PVC material, such as corrosion resistance and aging resistance (with a service life of more than 50 years4), FTDC can set up a global warehousing system to provide more than 10 years of spare parts supply for products such as pipes and cable jackets. For example, PVC pipe joints and other wearing parts can be realized within 72 hours of localized delivery, reducing the risk of customer downtime.
2. Technical response and customized services
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%.
