When Plastic Meets Minerals
The combination of PVC (polyvinyl chloride) and gypsum is like giving plastic a mineral armor:
Basic Properties: PVC provides flexibility and water resistance, while gypsum imparts hardness and fire resistance.
Mixing Ratio: Typically, PVC accounts for 30%-50%, with gypsum serving as a filler and reinforcing material.
Molding Characteristics: Can be cast or pressed; curing time is 40% shorter than pure gypsum.
This composite material holds many surprises:
Enhanced Moisture Resistance: 80% lower water absorption than pure gypsum, suitable for humid environments.
Weight Reduction: Density is higher than... Pure gypsum products are 25% lighter, facilitating transportation and installation.
Process-friendly: Can be cut with ordinary woodworking tools and won't break when nailed.
Cost control: Raw material costs are 30%-50% lower than pure PVC products.
Clever applications in daily life: You may have already seen them:
Decorative moldings: Ceiling moldings with a wood grain effect, crack-resistant and deformation-resistant.
Temporary partitions: Removable walls for exhibitions, fireproof and lightweight.
Creative ornaments: Sculpting bases for handmade projects, easy to shape and sturdy.
Industrial molds: Disposable mold shells for casting, with high detail reproduction.
