Why is our PVC material more environmentally friendly? Unveiling the safety commitment behind raw material traceability.
PVC (polyvinyl chloride) is a widely used polymer material in wire and cable, building materials, medical supplies, and even everyday household applications. For a long time, PVC has been misunderstood as "unfriendly" or "toxic," particularly due to its potential release of hydrogen chloride gas and dioxins when burned, sparking public concern. However, the truth is: PVC itself is neutral; its environmental performance depends crucially on its formulation and raw material sourcing.
We firmly believe that true environmental protection begins at the source. For this reason, in the research and development and production of PVC materials, we adhere to the principles of green formulas and full traceability, ensuring that every grain of PVC is "clearly sourced and safe to use."
1. Control at the Source: We Only Use "Fresh and Pure" Raw Materials
Ordinary PVC products often pose environmental risks due to the use of recycled and regenerated materials. These recycled materials, derived from complex sources, may contain heavy metals, impurities, and even harmful additives. This not only affects performance but can also release harmful substances during processing or use. Our PVC materials are designed to never use scrap or recycled materials. All resin raw materials are sourced directly from major domestic petrochemical companies, such as Sinopec and PetroChina, ensuring that every batch of PVC resin is brand new, virgin, and high-quality, complying with the GB/T 5761 standard.
We establish long-term strategic partnerships with our suppliers to ensure traceability of our raw materials. Each batch of resin has a unique batch number, documenting its production date, process parameters, and test reports, ensuring transparency and control at every stage from the oilfield to the factory.

2. Green Formula: Lead-free, Low-smoke, and Free of Banned Plasticizers
Traditional PVC materials often incorporate lead salt stabilizers or phthalate plasticizers (such as DEHP and DBP) to enhance flexibility and processing performance. These substances are listed as hazardous substances under EU regulations such as RoHS and REACH, and long-term exposure may affect human health.

We have completely eliminated these harmful additives and adopted more advanced environmentally friendly solutions:
- Stabilizer: We use a calcium-zinc composite stabilizer, replacing lead and cadmium with harmless metals such as calcium and zinc, achieving non-toxic stability. - Plasticizers: We use environmentally friendly, non-phthalate plasticizers such as citrate esters and DOTP. These plasticizers not only offer excellent flexibility but have also passed third-party testing such as SGS and CTI, complying with multiple international environmental standards, including RoHS, REACH, and PAHs.
- Flame Retardancy and Smoke Suppression: Halogen-free flame retardants such as aluminum hydroxide and magnesium hydroxide absorb heat and decompose during combustion, releasing water vapor, effectively reducing smoke density and toxicity, achieving low-smoke, halogen-free, or low-smoke, low-toxicity properties.
This means that our PVC materials minimize their impact on the environment and human health during production, use, and disposal.

III. Full Traceability: One Material, One Code, Responsibility at the Source
Environmental protection is not just a slogan; it's a verifiable commitment. We have established a full-process traceability system for PVC materials:

1. Raw Material Incoming: Upon receipt of each batch of resin and additives, a QR code is scanned to record information such as supplier, batch number, and test report.

2. Production Process: Process parameters are recorded throughout the mixing, extrusion, and pelletizing stages to ensure formulation consistency. 3. Finished Product Shipment: Each package of PVC material comes with a unique traceability code. Customers can scan the code on their mobile phones to view the batch's:
- Resin source
- Additive list
- Test report (e.g., heavy metal, phthalate, and halogen content)
- Environmental certification
This transparent management not only ensures our product integrity but also provides customers with peace of mind.

IV. Closed-Loop Management: Promoting Green Circulation While Adhering to the "Food Grade" Bottom Line

We support resource recycling but firmly oppose blind recycling. For industrial waste PVC, such as cable sheathing and construction scraps, we partner with professional environmental protection companies to sort and recycle it for energy, avoiding landfill contamination.

However, for products that come into direct contact with the human body or are used in high-security applications (such as wire insulation and medical catheter materials), we insist on using virgin material and never add any recycled ingredients, ensuring stable performance and long-term safety.

Conclusion: Environmental protection is a long-term journey from source to end.

The environmental friendliness of our PVC material stems not from promotional packaging but from rigorous raw material selection, continuous formulation optimization, and a strong investment in traceability systems. We believe that only by implementing environmental protection into every detail can we truly earn our customers' trust and leave a cleaner environment for future generations.
Choosing our PVC materials is more than just choosing a product; it's choosing a visible responsibility and peace of mind.
