The technical distinction between SPC and WPC is found in their base layer composition. SPC's core is composed of limestone powder, polyvinyl chloride, and stabilizers. This dense mixture provides a high degree of dimensional stability, meaning it remains rigid even in extreme temperature changes, making it ideal for sun-drenched rooms. WPC utilizes wood flour and foaming agents in the core; this air-infused structure creates a lighter, warmer feel underfoot with natural sound-dampening qualities. While both are waterproof, SPC is generally preferred for its hardness and resistance to heavy rolling loads, whereas WPC is favored for general residential comfort.

What technical properties distinguish SPC rigid-core from WPC luxury vinyl construction?
SPC (Stone Plastic Composite) is distinguished by a rigid limestone and polymer core that offers extreme indentation resistance. WPC (Wood Plastic Composite) uses a wood fiber and foaming agent core, providing more cushioning and acoustic dampening properties for indoor comfort.
