What are the raw materials for SPC flooring?

The composition of [SPC wall panels] relies on specific raw materials that provide their strength and functionality.

The primary raw materials for SPC wall panels include limestone powder, polyvinyl chloride (PVC), and stabilizers, which together create a rigid, durable, and waterproof product.

Dive Deeper into SPC Raw Materials

1. Limestone Powder

Limestone serves as the primary filler, providing rigidity and density to the panels. Its abundance makes it an eco-friendly and cost-effective choice.

2. Polyvinyl Chloride (PVC)

PVC² acts as the bonding agent, ensuring flexibility and resistance to water and chemicals.

3. Stabilizers and Additives

Stabilizers improve thermal stability and durability, while additives enhance specific properties such as UV resistance or fire retardance³.

How is SPC flooring manufactured?

The manufacturing of SPC wall panels⁴ involves a detailed and technologically advanced process.

SPC wall panels are produced through an extrusion process that combines raw materials into a single, high-performing composite panel.

Dive Deeper into the Manufacturing Process

1. Mixing

Raw materials like limestone powder, PVC, and stabilizers are mixed in precise proportions to form a homogeneous blend.

2. Extrusion

The mixture is fed into an extrusion machine where it is heated and molded into panels of desired thickness and dimensions.

3. Lamination

Decorative films or textures are laminated onto the surface to give the panels their aesthetic finish.

4. Cutting and Finishing

The panels are cut to size, and edges are polished for a smooth finish.

Quality Control

Each panel undergoes rigorous quality checks to ensure it meets international standards for strength, durability, and aesthetics.

What are the ingredients in SPC flooring?

The [ingredients used in SPC wall panels] play a critical role in their performance and sustainability.

SPC wall panels are made from a combination of limestone powder, PVC resin, stabilizers, plasticizers, and optional additives for enhanced properties.

Dive Deeper into SPC Ingredients

1. PVC Resin

A high-quality polymer that acts as the primary binder, ensuring flexibility and resistance to water and wear.

2. Plasticizers

Improve the flexibility and workability of the material during the manufacturing process.

3. UV and Fire Retardant Additives

Optional ingredients that enhance the wall panels’ resistance to UV³rays and fire, making them safer and more durable.

What are the materials in SPC flooring?

Understanding the materials in SPC wall panels⁵ reveals why they are so durable and versatile.

SPC wall panels consist of a rigid core layer made from limestone powder and PVC, a decorative film layer for aesthetics, and a protective wear layer to ensure longevity.

Dive Deeper into SPC Material Layers

1. Rigid Core Layer

This is the backbone of SPC panels, providing strength and dimensional stability.

2. Decorative Film Layer

Offers the visual appeal, mimicking natural materials like wood or stone with impressive realism.

3. Wear Layer

A transparent coating that protects the panel from scratches, stains, and daily wear and tear.

4. Optional Backing Layer

Some SPC wall panels include an additional backing layer for added soundproofing or insulation.

Conclusion

[SPC wall panels] are a marvel of modern engineering, combining raw materials like limestone powder and PVC with innovative manufacturing techniques. Their durability, aesthetic versatility, and environmental benefits make them a top choice for both residential and commercial applications.
