Our Quality Assurance
Quality is at the core of everything we do at Xinkailin. It influences not only the performance and durability of our floors but also the safety and comfort of the indoor environments where they are installed.
Guided by our vision to be a global leader in sustainable flooring materials, we deliver products that our partners can trust. By maintaining stable formulations, precise production controls, and environmentally responsible materials, our PVC flooring consistently performs to the highest standards and stands the test of time.

Verified Raw Materials for Safety and Sustainability

100% Virgin PVC Resin
Our flooring products are made exclusively from premium brand-new PVC resin. This is a high-purity plastic directly derived from petrochemical feedstocks, non-toxic, environmentally friendly, and recyclable. Unlike recycled or blended materials, it offers higher strength, stable quality, and complies with EU REACH, RoHS, and other international safety standards.

Phthalate-Free Plasticizers
We use SGS and EU-certified DOTP (Dioctyl Terephthalate), a phthalate-free plasticizer, to make rigid PVC flexible and durable. Its safety level meets the requirements for children's toys and infant care products, offering a safer, more eco-friendly alternative to traditional phthalates like DEHP/DOP.

Natural Mineral Filler
These inert inorganic materials are primarily ground calcium carbonate, sourced from limestone, chalk, or marble. They feature high brightness, low cost, and low wear characteristics. When added to the PVC formulation, they act as void fillers and reinforcement agents, increasing the overall density, durability, and heat resistance of the flooring material.

Eco-Friendly UV Coating
It's a specialized transparent surface treatment that cures instantly under UV light to form a tough polyurethane protective layer. It enhances the floor's wear resistance, prevents scratches and stains, and reduces fading from sunlight. The coating is considered safe and environmentally friendly, containing low or zero volatile organic compounds (VOC).

Raw Material Verification
Every batch of incoming PVC, mineral fillers, and additives is carefully sampled and tested. Only materials meeting strict standards for color stability, mechanical strength, and preliminary fire-resistance checks are approved. Traceability is maintained for every component, ensuring full documentation from supplier to production line.

Pre-Production Sample Testing
Before each production batch, the scheduled flooring model is pressed on a dedicated test machine to produce sample sheets. These samples are inspected for color accuracy, gloss, pattern alignment, and material performance to prevent differences from previous batches. This step allows our team to address potential discrepancies before full-scale production begins.
In-Process Monitoring
During production, eight dedicated quality inspectors work alongside skilled operators across four production lines. They monitor the floor sheet thickness, width, surface finish, and color uniformity in real time. During the first winding stage, multiple color comparisons are performed to maintain consistency within each roll.
Post-Production Stabilization
Once production is complete, the rolls are left to rest for several hours so the material can settle and maintain its shape. Each roll is then inspected by hand for color match, surface finish, and overall consistency. This final check helps ensure the flooring performs as expected before it is packed and shipped.
Final Certification
Before shipment, each roll goes through a final round of performance checks covering dimensional accuracy, wear resistance, flexibility, mechanical strength, and fire performance (B1 classification). The floor rolls that pass all checks move forward to packaging.
Quality Certificates
Certified to CE, REACH, FDA, SGS, and ISO standards, our products meet requirements in key markets including Europe, the US, Southeast Asia, and the Middle East.
